2019 Audi A4

The volume 45 TFSI quattro's EA888 2.0-liter turbo four makes 248 hp for 2019 — four down on the 252 hp the same car carried in 2018, and a competitive figure inside the compact luxury class but an ordinary one against a sedan band that reaches 520 hp.

273 lb-ft arriving from 1,600 rpm is the more flattering half of this powertrain's spec sheet — the flat turbo torque plateau is why the A4 feels quicker in traffic than its horsepower number suggests.

Audi's own 5.6-second claim is conservative — instrumented testing has beaten it by four tenths on quattro's launch traction. Genuinely quick for a mainstream compact luxury sedan without stepping up to the S4.

The 2.0T is quiet and unusually smooth for a turbo four, with strong midrange pull — but reviewers of this pre-facelift B9 consistently flag a beat of hesitation pulling away from rest, a mix of turbo spool, stop-start restart and dual-clutch takeup. 2019 carries no mild-hybrid assist in the US to smooth the restart, so it stays out of the top band.

The seven-speed S tronic dual-clutch shifts quickly and essentially invisibly once moving and never hunts the way a many-ratio torque-converter automatic can; its weakness remains the classic dual-clutch one at creep speeds. 2019 is the year the six-speed manual disappeared, so the S tronic is now the only gearbox in the range — that removes a choice but does not change how the automatic behaves, which is what this item grades.

quattro all-wheel drive is standard on every 248-hp 45 TFSI car and on the allroad and S4 — effectively the whole meaningful range — with front drive confined to the 188-hp 40 TFSI trim walk. It is a road-biased torque-distributing system with no low range or terrain modes, so it stops short of the top band.

Two tunes of one 2.0-liter turbo four — 188 hp FWD 40 TFSI and 248 hp 45 TFSI quattro — are the entire 2019 A4 sedan lineup, with the S4's 3.0T V6 above it as a separate model. No hybrid, plug-in or electric variant exists anywhere in the range, and with the manual gone for 2019 even the transmission choice has closed.

27 MPG combined for the volume quattro sedan is unremarkable for a 2.0-liter compact sedan — stop-start is standard but there is no electric assist in the 2019 US car, and all-wheel drive costs it three MPG against the front-drive 40 TFSI.

23 MPG in town is the weakest of the three EPA figures and the one a commuter actually feels — a MPG down on the 2018 quattro. Stop-start is standard, but with no hybrid hardware nothing recovers energy in traffic.

34 MPG highway is the A4's strongest EPA figure and holds level with the 2018 car — tall S tronic top gears, a slippery body and quattro ultra's ability to decouple the rear axle all pay off at a steady cruise. Notably the front-drive car gains nothing here, so the AWD penalty is confined to city driving.

413 miles between fills is below par for a compact sedan, and it is the small tank rather than the engine that binds — the same drivetrain would clear 460 miles on a segment-average fill.

$2,800 a year at EPA assumptions sits near the expensive end of the compact-sedan band. Mid-pack MPG is only half of it — the mandatory premium grade is what turns an ordinary economy figure into a genuinely costly one to run.

Every 2019 A4 drivetrain takes premium unleaded, with no regular-grade, diesel, flex-fuel or plug-in alternative in the US range — a standing surcharge of roughly 60–80 cents a gallon over regular. The engine will physically run on 87 AKI, but Audi's own manual states 91 AKI is needed to make the rated output, so the requirement is real. Normal for the compact luxury class, but this item grades the requirement itself rather than the peer group.

NHTSA did not crash-test the 2019 A4 — the agency's file for both the FWD and quattro body styles returns "Not Rated" across every test. The item asks for the latest tested year of the generation, and the structurally identical B9 A4 took 5 stars overall in 2018 and again in 2020, with the 4-star frontal result as the only soft spot both times.

A clean crashworthiness sheet — Good in all six IIHS evaluations, including both driver- and passenger-side small overlap — earning Top Safety Pick. It stops short of TSP+ because no 2019 headlight configuration rates better than Acceptable, and the award is explicitly restricted to cars fitted with the Prestige lights.

Sparse for a $38k luxury sedan. The volume Premium's standard driver-assistance list is Audi pre sense city (low-speed AEB with pedestrian detection), forward collision warning and a rearview camera — nothing else. Blind-spot monitoring and rear cross-traffic assist require the Convenience package, lane departure warning and adaptive cruise require the Driver Assistance package on Premium Plus or the step to Prestige, and NHTSA records both FCW and LDW as not fitted on the tested configuration.

The strongest part of the standard safety kit. Audi pre sense city takes Superior in both IIHS front crash prevention tests published for this car — vehicle-to-vehicle and daytime pedestrian — and 2019 is the first A4 model year covered by the pedestrian evaluation. It misses the top band only because IIHS never ran a nighttime pedestrian test on the B9 A4.

Audi side assist is alert-only — a mirror-mounted LED with no steering or braking intervention in the blind-spot function — and on the volume Premium it arrives only inside the Convenience package, bundled with keyless entry, memory seats and an alarm rather than sold as a standalone safety choice. It does bring rear cross traffic assist and pre sense rear (rear automatic braking) with it, and is standard from Premium Plus upward, so the hardware is available across the range.

The weakest ADAS result for 2019. The volume Premium has no lane assistance at all — even warning-only lane departure is unavailable on it, which is why NHTSA's file records LDW as not present. Audi active lane assist and the Traffic Jam Assist centering that rides with it need the Driver Assistance package on Premium Plus or the Prestige, and where fitted reviewers describe the tuning as imprecise rather than class-leading.

Good hardware, badly gated. Where fitted it is a full-speed-range stop-and-go system with Traffic Jam Assist layering low-speed lane centering on top — competitive for 2019 — but the volume Premium cannot be ordered with it at any price, Premium Plus needs the extra-cost Driver Assistance package, and only the $47,195 Prestige has it from the factory.

No hands-free highway driving is offered on the 2019 A4 in any trim or package, and Audi had no US answer to GM Super Cruise in this model year. Traffic Jam Assist, the top of the assistance stack, is an explicitly hands-on system that monitors steering-wheel contact.

The car's worst safety result, and 2019 is a low point even within the B9 run: no configuration earns Good. The volume Premium's HID projectors rate Marginal, and so do the Premium Plus's LED projectors without high-beam assist; only the Prestige's LED projectors with high-beam assist reach Acceptable. That single Acceptable is what the headlight-restricted Top Safety Pick hangs on and why the A4 misses TSP+.

Typical compact-luxury sightlines: a low cowl and reasonably slim A-pillars ahead, a rising beltline and thick C-pillars that pinch the over-the-shoulder view, with reviewers generally rating the B9's glass area better than average for a modern sedan. Camera and sensor compensation barely reaches the volume trim — the Premium ships with a rearview camera alone, since the front/rear parking sensors and the top-view 360-degree system both require Premium Plus or above.

The hardware is easy to live with — IIHS rates LATCH ease of use Good, with lower anchors that sit under simple covers and clearly marked tether anchors. What caps the score is packaging, not hardware: only the two outboard seats carry complete LATCH, the center position gets a tether anchor alone, and a compact sedan's rear legroom makes a rear-facing infant seat tight behind a tall front occupant.

The B9 A4 sedan is a conventional five-seater across Premium, Titanium Premium, Premium Plus and Prestige, with a three-place rear bench and no reduced-seat variant anywhere in the 2019 US range.

38.9 in is the published without-sunroof figure this item asks for and is unchanged from 2018 — 2019 is a carry-over year for B9 packaging, with only bumpers and trim structure altered. Almost no buyer saw the full figure: a sunroof is standard equipment on all trims and costs about two inches of it.

41.3 in sits low in the 40–44 in sedan band — the A4's front cabin is well shaped and easy to get comfortable in rather than notably long-legged, and the figure is constant across the whole B9 run including the 2019 facelift-lite.

37.4 in of second-row headroom is genuinely good for a compact sedan and lands above the middle of the 35–39 in band, helped by the B9's relatively upright rear roofline. Reviewers of the 2019 car specifically note adults sit comfortably on head- and legroom in back.

35.7 in remains the A4's clearest packaging weakness against a 32–42 in band that reaches into mid-size sedan territory, and 2019 changes nothing about it. Reviewers split on the result — some call the rear seat adult-usable, others call it tight.

13.0 cu ft is modest in absolute terms and sits low in the 10–20 cu ft sedan band. The 40/20/40 split-fold seatback with pass-through — standard on every 2019 trim including the base Premium — recovers real flexibility for long items but not bulky ones.

Conventional volumes with one genuine 2019 improvement: the Audi phone box wireless charging pad became standard content on the volume Premium Plus rather than an upper-trim option, so the car finally has a designed-in phone home instead of a bin and a cable, and two rear USB charge ports joined it. Bin, door-pocket and console volumes themselves are unremarkable and there is still no standout storage idea.

Front seats are a consistent strength — leather upholstery and heated power front seats are standard even on the base Premium, memory settings arrive with the Convenience package that is standard on Premium Plus, and testers rate both the standard and optional sport seats as good for hours of touring. The rear bench is the limiter: well shaped and unusually good on headroom, but 35.7 in of legroom stops this short of the band that requires praise front and rear.

Well judged rather than plush: reviewers of the 2019 car call ride compliance very good with a hint of buoyancy that stops short of float, and the standard suspension is firm in the German idiom but free of impact harshness. The 2019-standard S line package brings larger wheels and lower-profile rubber to every car, which works against outright compliance, and the optional adaptive dampers offer only a modest range of firmness.

One of the car's quieter virtues and slightly better regarded than the 2018 result: Consumer Reports found wind and road noise impressively hushed in a cabin it called tight-as-a-drum solid, and the 2.0T is quieter under load than most turbo fours. The audible intrusion is tire roar at highway speed, worse on cars fitted with the optional summer rubber.

Unusually generous core equipment for the era: tri-zone automatic climate with rear vents and rear temperature control, heated power front seats, leather and a sunroof are all standard on the base Premium, and the Cold Weather package adds heated rear seats and a heated steering wheel. The ceiling is the deduction — no 2019 A4 trim at any price offered ventilated front seats.

For 2019 the entry A4 is the 188-hp 40 TFSI Premium, and — as in 2018 and 2020 but unlike the 2022–2026 cars — it is front-wheel drive, so quattro and the 248-hp 45 TFSI engine are a $4,600 step up rather than standard. The base price is up $1,420 delivered on the 2018 car and sits $2,850 under a 2019 BMW 330i.

The volume 2019 A4 is the 248-hp 45 TFSI quattro in Premium Plus trim — US luxury-compact buyers overwhelmingly take AWD, and Premium Plus is where the 8.3-inch MMI with navigation, Virtual Cockpit, LED headlights, parking sensors, wireless charging and Bang & Olufsen audio live. Notably this is the most expensive volume trim of any B9 A4 in the catalog: 2019 folded the old Navigation & Telematics/Convenience content into Premium Plus, pushing it to $47,500 MSRP — $3,800 above the 2018 car and $3,500 above the 2020 facelift car, which unbundled some of it again.

Nothing is complimentary on a 2019 A4 — the owner pays from the first 10,000-mile service — and year 5 falls outside the 4 yr/50,000 mi warranty, exactly when a 2.0T with quattro hardware and a seven-speed S tronic dual-clutch starts generating bills. RepairPal rates the 2019 A4 quattro worse than either neighbouring year (3.0/5.0 and 21st of 31 luxury midsize cars, versus 3.5 and 14th for 2018 and 2020) at $925/yr, which compounds to roughly $4,600 in repairs alone before scheduled service, tires or brakes.

The 2019 A4's five-year mark landed in 2024 — after the 2021–23 used-market spike that flattered the 2018 car (51% retained) but before that support had fully unwound for the 2020 car (47%), so it slots between them. Real 2019 cars now trade around 37% of their delivered MSRP at seven years, which back-casts consistently to the high 40s at year five, and the A4 still depreciates slightly faster than the luxury-compact class average.

Audi's 4 yr/50,000 mi bumper-to-bumper matched BMW and Mercedes for 2019 and beats the 3 yr/36,000 mi mainstream standard, but trails Genesis and Jaguar at 5 yr/60,000 mi. Mid-band for the segment, and unchanged across the whole B9 run.

Audi publishes no standalone powertrain warranty, so the 2.0T TFSI, seven-speed S tronic and quattro hardware on a 2019 A4 are covered for exactly as long as the trim panels. That falls below the floor of the 5–10 year band this item normalizes against and is a fraction of the 10 yr/100,000 mi powertrain coverage Hyundai, Kia and Genesis offered in 2019.

No complimentary scheduled maintenance at all on a 2019 A4 — Audi Care is a prepaid plan bought on top of the car, and Audi Signature Care (3 yr/30,000 mi included service) did not arrive until MY2026. What is included is 4 years of Audi 24-Hour Roadside Assistance running alongside the warranty plus short Audi connect trials, so the owner pays from the first 10,000-mile service. That trailed the included-maintenance programs Volvo, Jaguar, Genesis and BMW (Ultimate Care, 3 yr/36,000 mi) all offered in 2019.

$49,200 volume-trim price minus its estimated resale value after 5 years (49% retained, or about $24,108) leaves about $25,092 in depreciation. Add the projected $7,500 in 5-year maintenance and repairs, and owning this vehicle for 5 years costs about $32,592 in total.

2019 is the strongest year of the B9 run on the owner record, and the two major predictors agree for once. Consumer Reports states the 2019 A4 is MORE reliable than other cars from the same model year — a direct reversal of its verdict on the 2018 car, which it called less reliable — and the reported trouble spots are thin and mechanical rather than systemic: water pump leaks, a turbo hose attachment, battery/'check electrical system' warnings, door rattles, one camshaft noise fixed under warranty. J.D. Power rates predicted reliability 3.5/5 (slightly above average) and RepairPal 3.5/5.0 with 0.4 unscheduled shop visits a year against a 0.6 luxury-midsize average. What keeps it out of the top band is that neither predictor is emphatic and the sample is small — CarComplaints logs only 7 complaints for the year — so the good reading rests on a thin base rather than on a Lexus-grade track record.

The car outperforms its badge here. J.D. Power's 2022 Vehicle Dependability Study is the cohort-exact read — it surveyed three-year-old vehicles, i.e. this 2019 model year — and the premium brands as a group came in worse than the mass market (204 PP100 vs 190, industry average 192), with no premium German brand among the five named leaders (Genesis 155, Lexus 159, Porsche 162, Cadillac 168, Lincoln 180). Audi's own figure for that study is not published in the public summaries, so it is not claimed here; the multi-year picture around it is clearly below average, with the 2025 VDS putting Audi at 273 PP100 against a 202 industry average — the worst of the German three, behind BMW at 189 and Mercedes-Benz at 243. Consumer Reports is kinder, placing Audi upper-middle among brands (around 13th), ahead of Mercedes and Land Rover but behind BMW, Lexus and Toyota. Mid-pack at best, trending down.

A genuinely clean year, and cleaner than the model years on either side. NHTSA lists exactly one recall for the 2019 A4 — the Passenger Occupant Detection System seat-heater cable contact fault that can disable the front passenger airbag — where the 2018 car carries four campaigns and the 2020 refresh brought its own infotainment trouble. Nothing touches powertrain, fire or brakes, and complaint volume is close to the floor: 7 reports at CarComplaints and roughly 8 at NHTSA, too few to establish a pattern. Held just short of the top band because the single recall is a safety-system defect rather than a trim item, and because it is Audi's second attempt at the same PODS circuit after the 2019 oxidation campaign on earlier B9 cars — plus 2019 shares the B9's routine service-bulletin items around the water pump and thermostat module.

The 2019 volume configuration is the 248 hp 2.0T EA888 Gen 3B with the seven-speed S tronic dual-clutch and quattro; the 188 hp front-drive 40 TFSI is the other engine, and the six-speed manual was dropped for 2019, so every US A4 that year runs the DCT. EA888 Gen 3 is among the highest-volume engine families in the world and had already put the Gen 1/2 chain-tensioner and oil-consumption faults behind it, which is what gives it a documented high-mileage record. It falls short of the top band on wear items rather than design risk, and the 2019 owner record names them directly — water pump leak and a turbo hose attachment issue, alongside the family's habitual composite thermostat module, PCV valve and direct-injection carbon buildup. The S tronic is mature and draws no complaint cluster for this year, but its mechatronics unit and clutch packs remain an expensive out-of-warranty exposure that a torque-converter automatic does not carry.

The B9 A4 set the material benchmark for the compact luxury sedan class and reviewers said so without hedging — Edmunds credits Audi with "setting new quality benchmarks for cabin materials and construction" and gives the A4 an explicit advantage over the Mercedes C-Class on how it is built. Every 2019 trim gets real leather where several rivals in the class fit simulated hide, with wood or aluminum inlays, satin metal accents and switchgear that operates with precise, damped action. It sits a couple of points below the facelifted car only on display hardware: the US 2019 A4 is still the pre-refresh car running MIB2 with the fixed non-touch screen and rotary MMI controller, and the 10.1-inch haptic touchscreen and higher-resolution Virtual Cockpit arrive with the 2020 model year.

Assembly is a real strength of this car: Ingolstadt-built, consistent panel gaps, a quiet structure, and reviewers calling interior fit and finish excellent and the cabin well put together throughout. The complaint record backs that up — 7 total complaints for the year, none of them assembly-related. Two things keep it in the upper-70s rather than the 80s. Consumer Reports' own 2019 trouble spots include door rattles traced to loose interior panel retaining clips, which is precisely a fit defect; and Audi's standing in J.D. Power's Initial Quality Study has been weak throughout this period, driven by electronics and infotainment faults rather than by how the car is screwed together — and 2019's electrical trouble spots (parking-sensor wiring harness, intermittent airbag lamp, battery warnings) are exactly what lands in an initial-quality survey.

Adequate coverage and a service reputation that was slipping in exactly this car's warranty years. Audi ran roughly 304 US dealerships in 2019 — good metro and suburban density but a long drive for rural and small-market owners, which matters for a car whose documented faults (the PODS airbag recall, parking-sensor harness, electrical accessories) are all dealer-only diagnostic work. On satisfaction, Audi had led every nameplate in J.D. Power's 2016 Customer Service Index at 874 and sat second and joint-third in 2017 and 2018, but it is absent from the 2019 study's named luxury top five (Porsche 893, Lexus 881, Cadillac 880, Infiniti 878, Mercedes-Benz 870) — good, not the standout it had been.

Expensive against the market as a whole and merely average against luxury peers. RepairPal puts A4 annual repair and maintenance at $739 versus $652 for all vehicles — level with the luxury-midsize average, so the premium is the segment's, not this model's — with a 13% chance any given repair is a severe one against a 12% norm. The 4-year/50,000-mile factory warranty on a 2019 car lapsed by 2023, so every fault on this year's record is now an owner-paid bill, and the ones actually reported are not cheap: a water pump/thermostat module job and a pinched parking-sensor harness are both labor-heavy. The EA888 has deep independent-specialist and aftermarket support, which genuinely helps, but the B9 is a longitudinal MLB Evo car rather than an MQB one and shares far less hardware with high-volume Volkswagens than an A3 does — quattro driveline, LED lighting assemblies and the MMI head unit are all dealer-priced.

2019 is the year MMI Navigation plus and its 8.3 in display moved from a $3,000 package into standard Premium Plus content, so the volume trim's screen grows from 7.0 to 8.3 in. Even so it sits near the floor of the 7–15.5 in sedan band, and the pre-facelift B9's display is not literally a touchscreen — the 10.1 in touch panel arrives with the 2020 facelift, not here.

The B9's MMI was widely rated among the best interfaces of its generation — function buttons cut from four to two, a rotary controller that nudges like a joystick to reach menus without looking away, and hard climate controls below the screen — and 2019 puts the better 8.3 in version with handwriting input on the volume trim as standard. Hardware age is what keeps it out of the top band: an 8.3 in 1024×480 non-touch panel with graphics the 2020 MIB3 car makes look dated.

Textbook middle band and unchanged for 2019: Audi smartphone interface carries both Apple CarPlay and Android Auto on every trim including the base Premium — genuinely ahead of BMW, which still charged for CarPlay — but both are wired-only through the front USB port. No B9 A4 supports wireless projection from the factory in any model year.

The single biggest 2019 gain in this category. Where the 2018 volume car had no native maps unless the buyer paid for the $3,000 Navigation & Telematics package, MMI Navigation plus — Google Earth mapping, destination voice entry, connected traffic over the embedded LTE modem — is standard on the 2019 Premium Plus. The base Premium still ships with no built-in navigation at all, which is what holds this out of the top band.

The strongest item in the category, because the flagship system is trim content rather than a line-item option: the Bang & Olufsen 3D Sound setup — 19 speakers, 16 channels, 755 watts — is standard on the volume Premium Plus. The base Premium's ten-speaker Audi sound system is clean but unremarkable, which is what keeps this from the very top of the band.

Audi virtual cockpit is one of the best digital clusters of its era — a crisp, configurable 12.3 in panel with full-screen Google Earth mapping — and 2019 is the year it became standard equipment on the volume Premium Plus rather than package content. Only the base Premium's analogue dials with a colour driver-information display keep this short of the top of the band.

No over-the-air vehicle software updating exists on the pre-facelift B9 in any year, and control-module software remains a dealer job. 2019 improves only the partial case: the embedded 4G LTE modem that Audi connect needs is now standard on the volume Premium Plus rather than package content, so a typical 2019 car at least pulls connected map, traffic and content data over the air.

myAudi with Audi connect covers the core set and, for 2019, covers it on the car people actually bought — vehicle status, remote lock/unlock, stolen-vehicle locator, send-to-car destinations, emergency call and a Wi-Fi hotspot, all standard on Premium Plus. The ceiling is remote start: the pre-facelift US A4 offers no remote engine start at any price, which is the function American owners most expect from a phone app, and there is no digital key.

Materially better than 2018 but still dated hardware. The volume Premium Plus adds two rear USB charge ports and a standard Audi phone box wireless charging pad to the two front USB-A/AMI ports, SD slots and 12-volt socket — genuine second-row provision where last year had none. There is still no USB-C anywhere, no household outlet, and the base Premium keeps the two front ports only.

Strong on the volume trim: the Convenience package is standard content on the 2019 Premium Plus, so Audi advanced key proximity entry with push-button start comes with the car, and Prestige adds a hands-free power trunk lid. It stays out of the top band because the base Premium has push-button ignition but still needs the Convenience package for proximity entry, and no 2019 A4 offers phone-as-key or remote start.

The strongest parking provision of the B9's pre-facelift years and ahead of the 2020 car, where sensors retreated into an option package. A rearview camera is standard on every 2019 A4; the volume Premium Plus carries front and rear parking sensors as standard; and Prestige moves up to a four-camera top-view surround system. Image quality is era-typical rather than high-resolution, and the automation is guidance rather than true self-parking.

A full-colour head-up display exists on the 2019 A4 but only as Prestige content — a Premium or Premium Plus buyer has no path to it at any price. That is the definition of the middle band's upper edge: good hardware, locked to the trim almost nobody buys, at roughly a $4,500 step above the volume Premium Plus.

The hardware is easy to live with and the space is not. IIHS rates the A4's LATCH ease of use Good, with anchors under removable covers rather than buried in the seat bight, and the rear door openings are square — but 35.7 in of rear legroom makes a rear-facing seat a real negotiation with the front passenger, and 13 cu ft of trunk behind a fixed bulkhead swallows one stroller and little else.

Good crash credentials with the useful equipment a trim step up from the entry price. The B9 A4 is a 5-star NHTSA structure and a 2019 IIHS Top Safety Pick with Good in all six crashworthiness tests and Superior front crash prevention, and Audi side assist with pre sense rear is standard on the volume Premium Plus — but no 2019 headlight configuration rates better than Acceptable, so it misses Top Safety Pick+, the base Premium ships only low-speed pre sense city AEB with no lane assistance at any price, and adaptive cruise stays extra-cost even on Premium Plus. There is no rear-occupant alert.

Better equipped for the back seat than most compact luxury sedans of its year, and 2019 closes the charging gap: tri-zone automatic climate with rear vents and rear temperature control is standard on every trim, rear headroom genuinely fits adults, the Cold Weather package adds heated rear seats, and the volume Premium Plus now carries two rear USB ports as standard. What holds it in the middle band is legroom and luggage — 35.7 in with a front seat set for an adult, and 13 cu ft for four people's bags.

A compact, easy-sightline sedan with a smooth engine, imperceptible shifts once moving and light, precisely damped controls — most of what a commute asks for. Two things keep it mid-band: the seven-speed S tronic dual-clutch hesitates pulling away from rest, which reviewers and owners of this pre-facelift car single out in stop-and-go traffic, and the 2019-standard S line package's larger wheels leave the ride firm enough over patched city pavement to register.

An expensive car to commute in, and marginally worse than 2018. The volume 45 TFSI quattro returns 27 MPG combined on 23 in the city — the figure a commuter actually feels, a MPG down on last year — and every 2019 A4 drivetrain requires premium unleaded, which the EPA prices at $2,800 a year. There is no hybrid, plug-in or regular-grade alternative anywhere in the range; the FWD 40 TFSI at 30 MPG combined is the only cheaper option and it gives up quattro.

Genuinely urban-friendly and better helped than the facelifted car: a 186-inch compact sedan with a low cowl, slim pillars and large glass, and the volume Premium Plus ships front and rear parking sensors plus a rearview camera as standard. The 38.1 ft curb-to-curb turning circle is the one demerit — quattro's front driveline costs steering lock, so tight three-point turns need an extra shuffle.

Not a work vehicle in any meaningful sense. The A4 sedan carries no US tow rating, has no bed or flat load floor, and offers 13 cu ft of trunk behind a fixed rear bulkhead. The split-fold seatback and centre pass-through are the only concession to awkward loads, and 248 hp under load means nothing without a hitch to put it through.

A leather-lined luxury sedan on the 2019-standard S line's larger wheels and lower-profile tires, serviced at dealer rates, is the opposite of a wear-friendly work tool — and the 4 yr/50,000 mi warranty with no separate powertrain term and no complimentary maintenance sharpens the point. The EA888 2.0T and quattro driveline are proven in high volume across the VW Group, which is what lifts this above the floor, but nothing about the car's interior, ground clearance or running costs survives abuse.

Essentially no work-oriented provisions: no onboard AC power, no household outlet, no bed or tie-down system beyond trunk hooks, no factory hitch or roof-rail attachment on the sedan body, and no upfit ecosystem. Four USB ports, two SD slots and a 12-volt socket are the entire power story, and every interior surface is a soft one.

Strong fundamentals for a tourer — Consumer Reports calls the cabin remarkably quiet and the seats good for hours of touring, the ride is compliant, and 34 MPG on the highway is competitive — but three limits keep it a good rather than superb mile-eater: a 15.3-gallon tank holds combined range to roughly 413 miles, premium fuel makes every stop dearer, and the fatigue-reducing adaptive cruise with stop-and-go and active lane assist remain extra-cost items the volume Premium Plus frequently left the lot without.

quattro all-wheel drive on the volume 45 TFSI is a real asset on a snowy or gravel access road and is what lifts this off the pavement-bound floor. Everything else works against it: sedan ground clearance, no factory roof rails or hitch on this body style, no onboard power, no flat-folding load floor and no terrain modes or low range. Audi's answer for this buyer in 2019 was the A4 allroad, which is a different vehicle.

More flexible than the segment norm at the seatback and hard-limited behind it. The 40/20/40 split-folding rear seatback with a centre pass-through — standard on every 2019 trim including the base Premium — takes skis or long boxes, but 13 cu ft is still a sedan aperture into a fixed trunk, with no roof rails, no hitch-mounted option and no underfloor storage beyond the spare well.

Composed and unusually grippy rather than playful. Instrumented testing of the 45 TFSI quattro recorded 0.97 g on the skidpad — a figure that would flatter a sports sedan — and reviewers credit sharp handling with very good ride compliance and no float. What keeps it below the segment's best is character: quattro's security and the S line chassis deliver cornering ability without the rear-drive adjustability a 3 Series or G70 gives back to the driver.

The A4's clearest dynamic weakness and the reason it does not rank with the class's driver's cars. The rack is accurate and consistently weighted, so the car goes where it is pointed, but Edmunds calls it numb regardless of which of the three Audi drive select settings is chosen — precise enough, and mute.

The strongest dynamic result. 149 ft from 70 mph is a genuinely short stop for a 3,700-lb luxury sedan on all-season-capable rubber, the pedal is firm and progressive rather than grabby, and reviewers single the brakes out by name. No regen blending to complicate the tune on this pure-gas drivetrain.

Smooth and strong once rolling — the 248-hp EA888 is quiet and vibration-free with a flat torque plateau from 1,600 rpm, and the seven-speed S tronic shifts essentially invisibly. The deduction is the classic dual-clutch fault at creep speeds: a beat of hesitation pulling away from rest, compounded by the standard stop-start restart, which reviewers and owners of the pre-facelift B9 flag consistently. 2019 carries the calibration over unchanged.

Near the top of what a turbo four can manage. The 2.0T is quieter and smoother under load than most rivals' four-cylinders, with no coarseness through the wheel or pedals, and Consumer Reports found the whole car tight-as-a-drum solid. It falls short of the top band only because the engine note itself is characterless — muted and synthetic rather than pleasant.

38.1 ft sits in the wide half of the 34–40 ft sedan band and is a real annoyance in parking garages on a car this compact — quattro's front driveline costs steering lock, so a tight three-point turn frequently becomes a five-point one. Unchanged across the B9 run.

One of the car's genuine strengths. Power front seats with a wide adjustment range and a tilt/telescoping wheel suit a broad range of drivers, the low cowl and slim A-pillars give a clear forward view, controls are logically placed with hard climate switches below the screen, and ingress and egress are easy for a low sedan. Thick C-pillars pinch the over-the-shoulder view, which is what keeps it out of the very top band.

Quick, grippy and satisfying to cover ground in, but not a car enthusiasts recommend for its own sake. 5.3 seconds to 60 and 0.97 g of grip are real, and the 2019-standard S line package at least gives it the visual intent — yet numb steering, a muted engine note and quattro's unflappable neutrality add up to a fast tool rather than a playful one. Buyers who want the segment's entertainment go to the 3 Series, the G70, or up to the S4.

The base 2019 Premium is well stocked on the things buyers touch — leather upholstery, a power sunroof, tri-zone automatic climate, LED ambient lighting, ten speakers, and Apple CarPlay and Android Auto as standard when BMW still charged for CarPlay and put leatherette in the base 330i. What holds it below the 2018 and 2020 cars is the screen and the driver aids: the pre-facelift 2019 A4 still ships a 7-inch non-touch MMI display run by a rotary controller — where the 2020 facelift made a 10.1-inch touchscreen standard on every trim, and the all-new 2019 BMW 3 Series arrived with a standard 8.8-inch display — while headlights are xenon and Virtual Cockpit, navigation, blind-spot monitoring and rear cross-traffic assist all sit behind the Premium Plus step. The base car is also front-wheel drive.

2019 is the weakest value point in the B9 run despite a still-competitive entry price. The 40 TFSI Premium at $38,395 delivered undercuts a 2019 BMW 330i by about $2,850 with standard leather and CarPlay both German rivals charged for, but the volume 45 TFSI quattro Premium Plus lands at $48,495 delivered — $3,800 above the 2018 equivalent and $3,500 above the 2020 facelift car — while still running a 7-inch base screen and xenon headlights. The all-new G20 3 Series arriving mid-2019 reset the class benchmark for tech-per-dollar and driver engagement at essentially the same money.

Seven sedan configurations for 2019 — Premium, Titanium Premium, Premium Plus and Prestige on the 188-hp front-drive 40 TFSI, plus Premium, Premium Plus and Prestige on the 248-hp 45 TFSI quattro — span $38,395 to $51,795 delivered, with the 349-hp S4 above and the A4 allroad wagon alongside, and S line and Black Optic appearance packages layering on top. The new-for-2019 Titanium Premium replaced the old ultra Premium/Premium Plus grades and adds a distinct sub-$40,000 entry point. Two gaps keep it just below the 2018 car: AWD is bundled to the more expensive engine rather than orderable on the base car, and the six-speed manual quattro that made 2018 unique was dropped for 2019.

26,072 US deliveries kept the A4 a mid-pack seller with more volume than any later B9 model year, but the trajectory was clearly negative — down 24% from 2018's 34,220 and the middle of a slide that would take it under 6,000 by 2024. The A4 sat third of the German three behind the C-Class and 3 Series in a segment being drained by compact luxury SUVs, and it lost ground in a year when Audi's own full-size sedans grew sharply.

2019 is peak Audi in the US by volume: 224,111 deliveries, a record and a tenth consecutive year of growth, with the four rings carrying real design-led aspirational pull and quattro functioning as a genuine engineering differentiator rather than a marketing word. The A4's cabin was still widely called the best in the compact luxury class. It sits a step behind BMW and Mercedes on outright prestige and on resale support, which is why this is a strong rather than a top score.

Scored on buyer benefit, 2019 was a good year to buy an A4: a pre-chip-shortage market, a declining sedan segment and a nameplate down 24% year-on-year meant real discounting plus stacked rebates, and documented 2019 transactions show roughly 5% off sticker before $4,750 in incentives — about 14% off MSRP all in — on top of an Audi loyalty offer. It is the opposite of the 2022 car, which sold at or over sticker with essentially no incentive cash. What holds it just short of the 2018 score is that Audi's lease programs were consistently less aggressive than its rivals' rather than best-in-class.

2019 is the third US model year of the B9 and the last before the facelift, which is the weakest freshness position in the generation. The car gains the RS 4-inspired S line front and rear bumpers and the 45 TFSI power/mild-hybrid update, but keeps the pre-facelift lighting and the rotary-controller MMI, and the refreshed 2020 car with its 10.1-inch touch display and revised lighting was already public by spring 2019. Meanwhile the all-new G20 BMW 3 Series landed mid-2019 on a fresh platform, making the A4 visibly the older design in the class. Mid-cycle rather than aging outright, since a full redesign was not near — the B9 ran through 2025.

The 2019 A4 remained well reviewed but stopped being the class pick. U.S. News scores it 8.5/10 and ranks it #4 in Luxury Small Cars — behind the #1 placings the 2018 and 2020 cars hold — the Car Connection gives it 7.0/10, and it carries an IIHS Top Safety Pick with Good ratings in all six crash tests. Against that, it took no major award for 2019, it is absent from Car and Driver's 2019 10Best list, and the newly launched G20 3 Series and the Genesis G70 (a 10Best winner that year) took the segment's comparison-test honours.
