2023 Audi A4

2023 is a carry-over year within the B9 generation (Wikipedia records the fifth-generation B9 from 2017 with no 2023 powertrain change; the year's revisions were equipment-level — standard LED headlights, B&O 3D audio on Premium Plus, adaptive cruise added to the Convenience package, an expanded Black Optic Plus package on 45 models). The volume US configuration remains the Premium 40 TFSI quattro: a 2.0L turbo four with a 12V mild-hybrid system rated at 201 hp. Modest for a compact luxury sedan and behind the base engines of the BMW 330i and Mercedes C 300.

236 lb-ft from the 40 TFSI's 2.0L turbo, on a broad low-rpm plateau that makes the car feel stronger in traffic than its horsepower figure implies. Mid-pack for the compact luxury class.

Audi's own 2023 claim for the volume 40 TFSI quattro is 6.3 seconds — squarely mid-pack for the segment and behind a BMW 330i. The optional 45 TFSI is a full second quicker, claimed at 5.2 s and instrumented by Edmunds at 5.3 s.

The 2.0T with 12V mild hybrid is quiet and smooth in ordinary driving — reviewers of the 2023 car describe it going about its business smoothly and quietly, with the stop-start restart barely felt — but throttle and drivetrain responses are noted as occasionally delayed off idle, and the four gets coarse near its redline. Good rather than class-leading against the BMW B48 and Mercedes M254 fours.

The seven-speed S tronic dual-clutch — standard on every 2023 A4 — shifts quickly and cleanly once rolling, with good shift timing and rev-matched paddle downshifts, but low-speed manners are its weak point: delayed take-up and abrupt engagement when creeping or parking, the known wet-clutch DCT trait. That leaves it behind the 3 Series' ZF torque-converter eight-speed.

quattro all-wheel drive is standard on every 2023 US A4 — there is no front-drive variant — with the part-time-decoupling quattro ultra system on the 40 TFSI and a mechanical center differential with torque vectoring on the 45 TFSI. Sophisticated for on-road use; short of the top band only because there is no low range or terrain hardware, which nothing in this segment offers.

Two states of tune of one engine — the 2.0L turbo four as 40 TFSI (201 hp) or 45 TFSI (261 hp), both with a 12V mild hybrid and the same seven-speed DCT and quattro. No hybrid, plug-in or electric A4 sedan for 2023; the S4's 3.0T V6 and the e-tron cars are separate nameplates, and the diesel and Avant variants are not sold in the US.

The volume 40 TFSI quattro rates 28 MPG combined for 2023 — one point below the same drivetrain in 2022 (29) and two below 2024 (30). The dip is real and year-specific, not a carry-over error: EPA's certification family for this entry is unchanged apart from the model-year prefix (NVGAJ02.0A7E → PVGAJ02.0A7E → RVGAJ02.0A7E), so 2023 is a re-certification result on the same hardware rather than a mechanical change, and it lands the car mid-pack among gas sedans.

24 MPG city is where the 2023 car gives up most ground — the same drivetrain was rated 26 in both 2022 and 2024, and the unadjusted city figure fell from 33.3 to 31.0 MPG. Acceptable for standard quattro AWD with a 12V mild hybrid doing stop-start and coasting duty, but well short of a full hybrid rival and, unusually, no better than the more powerful 45 TFSI.

33 MPG highway remains the A4's strongest efficiency figure — the seven-speed DCT's tall top gear and quattro ultra's ability to decouple the rear axle pay off at a steady cruise, and the highway cycle barely moved year over year (unadjusted 49.0 in 2022 to 48.3 for 2023) even as the city rating fell.

EPA total range of 428 miles from the 15.3-gallon tank — below mid-pack for a compact sedan, and it is the small tank rather than the engine that caps it: the same drivetrain would clear 500 miles on a segment-average fill. The 2023 rating dip costs roughly 16 miles against the 2022 car and 31 against the 2024.

$2,700 a year at EPA assumptions — $100 more than the 2022 car and $150 more than the 2024, tracking the softer 2023 ratings. The economy figures themselves are middling rather than bad; it is the mandatory premium grade that pushes running cost well clear of a mainstream sedan's, and EPA flags $2,500 in extra fuel spend over five years versus the average new vehicle.

Premium unleaded is specified for every 2023 A4 drivetrain, with no lower-grade, flex-fuel or plug-in alternative — a fixed surcharge of roughly 60–80 cents a gallon over regular that puts this in the item's bottom band. Standard practice for the compact luxury segment, but the item grades the requirement itself rather than the peer group.

NHTSA tested the 2023 A4 4-door AWD directly and awarded 5 stars overall. Frontal remains the weak leg at 4 stars for both driver and passenger, while side barrier, side pole and rollover all earned 5 — the same result pattern as the 2022 and 2024 cars.

The 2023 A4 is the strongest IIHS year of the B9 generation: a full Top Safety Pick+ with no headlight restriction, where the 2022 car managed only a restricted Top Safety Pick and the 2024 car earned nothing. The upgrade is not a crash-structure change — every crashworthiness result is the same Good — but the new standard LED headlights lifted the Premium trim out of Marginal, and TSP+ requires acceptable-or-better lighting on every trim. It stops short of the top band because the award is granted under the 2022 criteria; the A4 was never run through the updated side or updated moderate overlap tests the 2023 criteria demand, and is absent from the 2023 award list.

The volume 40 TFSI Premium still ships thin for a $41k luxury sedan — pre sense city AEB with pedestrian detection, forward collision alert, lane departure warning, high-beam assist and a rearview camera, with nothing that steers or holds a gap. What changed for 2023 is that adaptive cruise was added to the Convenience package, so a Premium buyer can finally option ACC at all; it was unavailable at any price in 2022. Everything else that matters — side assist, rear cross-traffic, parking sensors — still costs $2,500 as a bundle, and Audi active lane assist remains a Premium Plus item until 2024.

Pre sense city takes Superior in both IIHS front crash prevention evaluations run on this car — vehicle-to-vehicle and daytime pedestrian — and the pedestrian sheet is spotless, avoiding the collision outright in every crossing-child and crossing-adult run. It is held out of the top band only because IIHS never ran a nighttime pedestrian or updated vehicle-to-vehicle test on the B9 A4.

Audi side assist is alert-only — a mirror-mounted LED with no steering or braking intervention — and on the volume Premium it remains bundled rather than standalone, now inside the $2,500 Convenience package. It does bring pre sense rear (rear automatic braking) with it and is standard from Premium Plus up, so every trim can have it; it simply isn't fitted to the car most buyers order.

The volume Premium gets lane departure warning only — it beeps, nothing steers. Audi active lane assist and the Traffic Jam Assist centering that rides with adaptive cruise still require the step up to Premium Plus, one model year before Audi made active lane assist standard across the A4 line, and reviewers rate the tuning mid-pack even where it is fitted.

2023 is the year the volume trim stopped being locked out: adaptive cruise moved into the Convenience package, so a Premium buyer can order the full-speed-range stop-and-go system with Traffic Jam Assist instead of having to move up a trim, as 2022 required. The system itself reviews well — smooth gap-keeping with lane-centering support layered on. It sits mid-upper band rather than higher because ACC is still a $2,500 option on the car most people buy, a year before Audi made it standard.

No hands-free highway driving is offered on the 2023 A4 at any trim — there is no Audi analogue to GM Super Cruise, Ford BlueCruise or Tesla FSD Supervised in the US lineup. Traffic Jam Assist is explicitly a hands-on system requiring the driver to keep hold of the wheel.

This is the 2023 A4's real safety story: new standard LED headlights with the DRL signature pulled the volume Premium up from the Marginal rating it carried in 2020-22 to Acceptable, which is what unlocked the unrestricted Top Safety Pick+. It is still not a good result in absolute terms — the Premium and Premium Plus share LED projector low beams with cheaper LED reflector high beams that go inadequate on the left side of the straightaway, and Good lighting remains a Prestige exclusive — but automatic high-beam assist is standard across the range and no trim is left in the Marginal band.

The B9 body gives typical compact-luxury sightlines — low cowl and reasonably slim A-pillars ahead, a rising beltline and thick C-pillars that pinch the over-shoulder view behind. Camera and sensor compensation on the volume trim is still thin: the Premium ships with only a rearview camera, since front and rear parking sensors sit inside the optional $2,500 Convenience package and the top-view 360-degree system requires Premium Plus.

The hardware is genuinely easy to live with — IIHS rates LATCH ease of use Good, with visible lower anchors needing zero pounds of attachment force and clearly labelled tether anchors. What caps the score is space rather than hardware: only the two outboard positions carry complete LATCH, the centre is tether-only, and a compact sedan's rear legroom makes a rear-facing infant seat behind a tall front occupant tight.

Conventional five-seat compact luxury sedan layout across all six 2023 A4 sedan configurations (Premium, S line Premium, Premium Plus, S line Premium Plus, Prestige, S line Prestige) — no four-seat variant is offered. 2023 is a carry-over year inside the B9 generation (US 2017–2025, facelifted for 2020), so the body and seating layout are unchanged.

38.9 inches is the published no-sunroof B9 figure, which is what this item asks for, and it is unchanged for 2023 — no sheetmetal or roof change from 2022. Worth knowing that no US A4 is actually sold without a sunroof, so the practical figure aggregators list is about 37 in.

41.3 inches is the B9 sedan figure carried unchanged into 2023 — adequate but not generous, and a reminder that the A4 is a genuinely compact car whose front footwell trails larger-in-class rivals.

37.4 inches of second-row headroom is mid-pack for a compact luxury sedan and is the one rear dimension that is not a weakness — the fastback-ish roofline still clears most adults' heads, which is more than the legroom figure manages.

35.7 inches is the A4's defining space compromise and is unchanged for 2023 — Edmunds reports there is not a lot of head or leg room in back for anyone six feet or taller, and two adults are the realistic rear capacity rather than three.

12.0 cubic feet is near the bottom of the compact luxury sedan class and unchanged for 2023. Edmunds notes the A4 partly compensates with a generous trunk opening and useful cutouts, but the raw figure is what this item measures.

Everyday storage is tidy but tight and offers nothing inventive — a shallow, awkwardly square tray ahead of the shifter that holds a phone poorly, a shallow bin under the center armrest, and usable but small door pockets. 2023 is a step up from 2022 because the Audi phone box wireless charging cradle is standard on Premium Plus and semiconductor-driven deletions had largely eased by the 2023 build year, though scattered 2023 cars were still delivered without it. No underfloor tray, no fold-flat surfaces, no onboard AC power.

Front seats are a genuine strength — leather upholstery with heated, power-adjustable front seats is standard on every 2023 trim including the base Premium, and Edmunds describes them as firm in the German manner yet plenty comfortable on long road trips. The rear bench is the limiter: nicely finished but short on legroom with a shallow thigh cushion for taller passengers.

The standard suspension on the volume 40 TFSI Premium is unusually well judged for an Audi — reviewers describe a supple ride that controls body motions well over broken pavement without ever turning harsh, and the car feels tight-as-a-drum solid underneath it. The S line trims' sport suspension and larger wheels (the 45 TFSI moved to standard 19-inch wheels on summer tires for 2023) give up some of that compliance.

One of the 2023 A4's most-praised traits — reviewers repeatedly call the cabin very quiet and credit the hush with masking long-distance miles. It stops short of the top band because at least one review found more wind and tire noise than expected for the class, and the dual-pane acoustic front side glass that fixes it is a Prestige item.

Standard content is decent — tri-zone automatic climate control with rear vents, leather upholstery and heated power front seats on every trim, plus app-based remote start through Audi connect. But 2023 still sits one model year before Audi made the heated steering wheel standard across the A4 line: here it rides inside the Convenience package on the base Premium (standard from Premium Plus up), and ventilated front seats remain an extra-cost item even at the top of the range. Key comfort kit costing extra is squarely the middle band.

The entry 2023 A4 is the 201-hp 40 TFSI Premium at $40,300, about $400 above the 2022 car, and quattro AWD plus the 7-speed dual-clutch remain standard on every A4 — so this is an all-wheel-drive price where a 2023 BMW 330i and Mercedes C 300 still start rear-drive. Mid-band for the sedan normalization range.

Premium Plus is the volume A4 trim and for 2023 it is the one worth buying — Bang & Olufsen 3D audio became standard equipment on Premium Plus this year, on top of Virtual Cockpit Plus and the top-view camera. Splitting between the 40 TFSI and the 261-hp 45 TFSI S line and adding metallic paint or the Convenience package (which is where adaptive cruise lives for 2023) puts real orders near $47,600, about $700 above the equivalent 2022 car.

Nothing is included on a 2023 A4 — the first paid service lands at 10,000 miles — and years 4–5 fall outside the 4 yr/50,000 mi warranty, exactly when a turbocharged four with quattro hardware starts presenting bills. RepairPal's $925/yr average for the 2023 A4 quattro alone compounds to roughly $4,600 in repairs before scheduled maintenance, tires or brakes.

Real 2023 cars are three years old now and appraise around $23,300 private party — about 56% of the $41,395 delivered base and roughly 49% of the $47,600 volume-trim price — which points to the mid-to-high 40s at the five-year mark. The 2023 car got less of the inflated-used-market support that propped up MY2022 residuals, and the A4 depreciates faster than its own class average.

Audi's 4 yr/50,000 mi bumper-to-bumper matches BMW and Mercedes for 2023 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.

Audi dropped its separate, longer powertrain warranty from MY2020, so the 2.0T and S tronic in a 2023 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-year powertrain coverage from Hyundai, Kia and Genesis.

No complimentary scheduled maintenance whatsoever on a 2023 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 unlimited-mileage Audi 24-Hour Roadside Assistance running alongside the warranty plus short Audi connect trials, which leaves the owner paying from the first 10,000-mile service and trails the included-maintenance programs at Genesis, Volvo, Jaguar and BMW's then-current Ultimate Care.

$47,600 volume-trim price minus its estimated resale value after 5 years (47% retained, or about $22,372) leaves about $25,228 in depreciation. Add the projected $7,900 in 5-year maintenance and repairs, and owning this vehicle for 5 years costs about $33,128 in total.

The model-level record is the best of any recent A4 and the brand-level record is still poor, so the score sits above the segment median without reaching the top band. Consumer Reports rates the 2023 A4 "much more reliable than other cars from the same model year" — a step up from the wording on the 2022 car — and NHTSA lists zero recalls and only seven owner complaints against the 2023 sedan after three-plus years on the road. Pulling the other way, the 2023 model year is exactly the cohort surveyed by the J.D. Power 2026 VDS at three years old, where Audi posted 244 PP100 against a 204 industry average, and CR's own trouble-spot breakdown still flags minor transmission (gear selector, shift software), body hardware (rattles) and in-car electronics.

Audi's dependability standing over this period is below average and the on-point study is the unflattering one: the 2026 VDS measures precisely this car's model year at three years old and put Audi at 244 PP100 against a 204 industry average — fifth from the bottom of the brand table, behind Mercedes-Benz (235) and well behind BMW, and a long way from Lexus at 151. Initial quality is no better: Audi finished dead last of all brands in the 2025 IQS at 269 PP100, and in the 2023 IQS only Volkswagen, Chrysler and Volvo ranked below it against a 192 PP100 industry average. Consumer Reports is the dissenting voice, placing Audi in the upper-middle of its brand rankings ahead of Mercedes-Benz and Land Rover, which is what keeps this out of the bottom band.

The 2023 A4 sedan carries no NHTSA safety recalls at all — three-plus model years on the road with a clean sheet, against three campaigns on the otherwise-identical 2022 car (including an ECU that could stall the engine and an infotainment unit replacement) and three on the 2023 BMW 330i. Complaint volume is correspondingly thin at seven filings, the substantive ones being two stall/electrical-shutdown reports and two false Audi Pre Sense braking activations. It stops short of a perfect record because service activity exists below the recall line: owners report a transmission-software campaign (37P3) and CR's survey flags gear-selector and shift-quality complaints, and the OEM Continental ProContact GX tire fitted to some MY21+ A4/A5s was itself recalled by Continental under 24T-009 — a tire-maker campaign, not an Audi defect, but one that reaches these cars.

Mechanically the 2023 A4 is a straight carry-over — both outputs, the 40 TFSI at 201 hp and the 45 TFSI at 261 hp, are the EA888 evo4 2.0T with 12-volt mild-hybrid assist, driving a seven-speed S tronic and quattro as standard. The engine half is the strong half: a fourth-generation refinement of a family in continuous production since 2008, with the early oil-consumption and chain-tensioner faults engineered out, and B9 examples routinely passing 125,000 miles without major powertrain work — specialists call B9 the most reliable A4 generation to date. What holds it to the middle band is maintenance-sensitive hardware that surfaces on cars this age: the plastic water-pump/thermostat housing that commonly fails around 60,000 miles at $1,100–$1,700, intake-valve carbon buildup inherent to direct injection at 70,000–90,000 miles, and the DL382 wet-clutch DCT, far better than VW's dry DQ200 but prone to shudder and mechatronic faults when its "lifetime-fill" fluid is never changed.

The B9.5 cabin is a segment benchmark and 2023 is squarely inside it, with the basic cabin design carrying over untouched from 2022: soft leather upholstery and heated power front seats standard, a soft-touch dash top and door panels, Virtual Cockpit and MMI, and reviewers consistently naming the cabin the reason to pick an A4 over a 3 Series or C-Class. It falls short of the top band only for the cost-downs reviewers single out at this price — a hard glovebox door and hard console sides.

Physical assembly on the Ingolstadt/Neckarsulm-built A4 is a genuine strength — reviewers describe interior fit and finish as excellent, with tight panel gaps and solid, well-damped switch action. The 2023 car also escapes the electronic black mark that pulled the 2022 down: there is no infotainment head-unit recall on this model year, where the 2022 needed a fleet-wide MMI unit replacement. It stays out of the 80s because the survey data still finds squeaks and screens — Consumer Reports lists body hardware (rattles, door/window issues) and in-car electronics among the 2023 A4's trouble spots, one owner needing several attempts to chase down an interior rattle, and infotainment remains Audi's worst initial-quality category.

Roughly 300–315 franchised US Audi dealers cover all 50 states and reach metro and suburban buyers comfortably, but the footprint is visibly thinner than BMW's or Mercedes-Benz's and rural owners can face long drives to a certified shop. Service satisfaction is measurably below par for a luxury brand rather than merely unremarkable: in the J.D. Power 2023 Customer Service Index Audi scored 848 against a 864 premium-segment average, ninth among premium brands, with Lexus on 900. Competent and well-equipped, but not a reason to buy the car.

Parts flow reliably through VW Group's US supply chain and the EA888 has broad enthusiast aftermarket support, but this is an expensive car to keep and a 2023 is now at or past the end of its 4-year/50,000-mile warranty, so the bills land on the owner. RepairPal rates the A4 Quattro — which is what every 2023 A4 is, quattro being standard across the range — 3.0 out of 5.0, 21st of 31 luxury midsize cars, at $925 average annual repair cost against a $652 all-vehicle average, with repair frequency above normal though severity average. Headline jobs are dealer-priced: the common water-pump housing alone runs $1,100–$1,700.

Every 2023 A4 gets the same 10.1-inch MMI touch display, so there is no trim penalty — but there is also no upgrade path, and 10.1 inches is small against 2023 rivals fitting 12-inch-plus screens. The screen carried over unchanged from 2022.

MMI touch response on the MIB3 hardware is quick, logically laid out and high-resolution, with haptic click confirmation that cuts false inputs — and critically, Audi kept a separate physical climate panel below the screen rather than burying temperature in menus. Held out of the top band by the small display and by the deletion of the old rotary controller, which made inputs on the move easier than reaching for glass.

Phone projection is standard on every 2023 A4, but only half of it is wireless: Apple CarPlay connects over the air while Android Auto is still wired across the entire range. That asymmetry is exactly this item's middle band, and it is a real limitation of the aging B9 head unit rather than a trim-level gap.

Audi's natural-language voice assistant handles destination, phone, media and climate requests conversationally and was better than the segment average in 2023, but factory navigation is not on the volume car — MMI Navigation plus arrives via the extra-cost Navigation package on Premium and Premium Plus and is standard only on Prestige. Most 2023 A4 buyers navigate through CarPlay, which is exactly what this band describes.

This is the 2023 A4's single biggest technology gain: the 19-speaker Bang & Olufsen 3D sound system, an option on 2022's Premium Plus, became standard equipment on Premium Plus for 2023 — so the volume trim now ships with one of the better premium systems in the compact luxury class. The standard 10-speaker unit on the base Premium is clean if unremarkable.

The volume Premium Plus and up get the 12.3-inch Audi virtual cockpit plus as standard — still one of the sharpest and most configurable clusters on sale, with essentially no lag — but the base Premium makes do with a small colour driver information display between conventional analog gauges. Full digital on upper trims only, at the top of that band because the cluster itself is excellent once you have it.

The B9's MIB3 head unit pulls navigation map and connected-services data over the air through Audi connect, but there is no whole-vehicle OTA on this platform — control-module and feature updates still require a dealer visit, and Audi shipped no feature-adding software drops to 2023 A4 owners. Infotainment-data-only capability, low in that band because the map updates themselves depend on an Audi connect subscription once the trial lapses.

myAudi with Audi connect CARE covers the core set — remote lock/unlock, remote engine start, vehicle status, stolen-vehicle locator and emergency call — and CARE runs complimentary rather than being subscription-gated from day one. It sits mid-band because there is no phone-as-key on the A4 at any trim, Audi offers no key-fob remote start (app only), and the app carries a long-standing owner reputation for slow refreshes and login trouble.

USB-C data/charge ports cover both rows and the Audi phone box — wireless charging with a signal booster — is standard equipment on Premium Plus and up for 2023, a real improvement on 2022 when semiconductor deletions meant many cars that nominally had it were built without. The base Premium still goes without wireless charging unless the Convenience package is ordered, and there is no household AC outlet anywhere in the car.

Push-button start is standard on every 2023 A4 and Audi Advanced Key proximity entry with hands-free trunk release is standard from Premium Plus up, riding inside the Convenience package on the base Premium — so the entry car still needs the fob in hand unless the buyer pays. Remote start is app-only through myAudi, and there is no digital or phone key on this platform at any trim.

A rearview camera is standard on every 2023 A4, and Premium Plus adds both front/rear acoustic parking sensors and the top-view 360-degree camera system as standard — a genuinely strong provision on the trim most buyers order. The base Premium is thinner, needing the Convenience package for the sensors, and Park Assist automated parking stays a Prestige feature.

A head-up display exists on the 2023 A4 but only as standard equipment on the top Prestige trim — it cannot be added to the Premium or Premium Plus at any price, so the buyer of the car most people order has no path to it. Textbook "HUD limited to top trims" placement.

The hardware is easy — IIHS rates the 2023 A4's LATCH ease of use Good, with two rear positions carrying complete attachment hardware and a third with a tether anchor — but the packaging fights it. With 35.7 inches of rear legroom a rear-facing seat pushes the front seatback forward, and the 12 cu ft trunk struggles with a full-size stroller plus a week's gear. Workable for one child, not for full family logistics.

The crash credentials are strong — NHTSA 5 stars overall and IIHS Good in every crashworthiness evaluation, with Audi pre sense city rated Superior for both vehicle-to-vehicle and daytime pedestrian front crash prevention. What holds it back is what the trims families actually buy carry: 2023 is one model year before Audi made adaptive cruise and active lane assist standard on the A4, so on the volume Premium those and blind-spot monitoring live inside the extra-cost Convenience package, headlights rate only Acceptable on Premium and Premium Plus (Good on Prestige alone), and the A4 sedan did not make IIHS's 2023 Top Safety Pick list at all.

Four adults travel in genuinely quiet, well-damped comfort, with tri-zone climate reaching the second row on every trim and a supple ride that keeps fatigue at bay. Capacity and rear amenities are what cap it: 35.7 inches of rear legroom, no rear entertainment of any kind, and a 12 cu ft trunk that cannot hold four people's luggage without folding a seatback.

Most of the commuter case is strong — quiet cabin, compliant ride, light and precise controls, standard quattro for bad weather and excellent forward ergonomics — and 2023 fixes 2022's worst commuter gap by making adaptive cruise with traffic jam assist orderable on the base Premium through the Convenience package (it is standard on Premium Plus). It stops short of the upper band because the seven-speed S tronic's low-speed take-up is still jerky exactly where a commuter spends its time, and ACC is content the volume buyer still has to pay for on the entry trim.

28 MPG combined is respectable for a compact luxury sedan with standard all-wheel drive and a 12V mild hybrid, but every 2023 A4 requires premium unleaded, which is what does the damage — EPA puts the annual fuel bill at $2,700 for the volume 40 TFSI quattro and $2,800 for the 45 TFSI. Add Audi dealer service rates with no complimentary scheduled maintenance and the per-mile commuting cost lands well above class-average.

A compact 188-inch footprint is easy to place and the volume Premium Plus now carries both front/rear acoustic sensors and the top-view 360 camera as standard, which makes tight city work genuinely easy. Two things keep it out of the upper band: the 38.1-foot turning circle is wide for the size — a consequence of the longitudinal engine pushing the front axle rearward — and the base Premium still ships with a rearview camera alone unless the Convenience package is ordered.

Audi publishes no US tow rating for the A4 sedan at any 2023 trim, there is no bed or open load floor, and the 12 cu ft trunk behind a sedan aperture is the extent of its load capability. It is not a work vehicle in any meaningful sense.

The EA888 2.0T and the B9 chassis are well-proven after seven model years, but everything wrapped around them is luxury-oriented and expensive to abuse: leather upholstery with no wear-friendly alternative offered, low-profile tires (19-inch summer rubber is now standard on the 45 TFSI), roughly five inches of ground clearance and Audi-level repair costs. There is no fleet or commercial version of the A4 and no work-spec interior.

Effectively nothing to work with: no onboard AC power or inverter, no bed or open cargo area, no tie-down system beyond trunk hooks, no factory roof rails on the sedan, and an accessories catalog limited to cargo nets, liners and a base carrier. There is no upfitter ecosystem for a compact luxury sedan, and the carpeted trunk and leather cabin are the opposite of washable.

This remains the A4's best use case — the cabin is hushed, the ride is supple enough to mask long-distance miles, the firm front seats hold up over a full day, and roughly 500 highway miles from 15.3 gallons at 33 MPG is a long stint between stops. What keeps 2023 out of the upper band is the driver-assist half: adaptive cruise with traffic jam assist is standard only from Premium Plus and is a paid package on the base Premium, and even at its best it is hands-on lane centering with no hands-free mode.

Standard quattro all-wheel drive is a real asset on gravel, snow-covered forest roads and boat ramps, and it comes on every 2023 A4 rather than as an upcharge — a genuine advantage over rear-drive rivals. Everything else is against it: roughly five inches of ground clearance, low-profile tires, no factory roof rails on the sedan, no 120V outlet, and no published tow rating, so a bike or ski rack has to work off a trunk-lid or aftermarket solution.

The 40/20/40 split-folding rear seatback with a center ski pass-through handles skis and long boxes better than 12.0 cu ft implies, and Edmunds credits the trunk with a generous opening and practical cutouts. But the raw figure is near the bottom of the class, there is no underfloor storage, no factory hitch and no roof rails on the sedan — so once the trunk is full, bulky gear has nowhere to go.

Standard quattro and a well-sorted B9 chassis give the A4 secure, composed cornering with genuinely good body control — 2023 reviews describe handling as nimble and precise with a firm-yet-supple ride and a tight-as-a-drum structure. It stops short of the class benchmark because the consensus is competent rather than involving: the nose-heavy longitudinal layout and safety-first tuning keep it behind a 3 Series or G70 for a driver who wants to be part of it.

Precision is not in dispute — the rack is accurate and tracks faithfully, and owners describe it as fluid yet accurate. Feedback is the problem: Edmunds singles the steering out as a letdown because it tells the driver nothing about the surface or how much grip is left. Accurate but numb is the definition of the middle band, and it remains the A4's clearest dynamic weakness in 2023.

Brakes are a strong point: a firm, progressive pedal that reviewers call responsive, with no regen-blending awkwardness since the 12V mild-hybrid system does not alter pedal feel. Instrumented stops for the B9 A4 land in the low-110-foot range from 60 mph, comfortably inside class norms; fade resistance is untested at length on the volume 40 TFSI's smaller rotors.

Once rolling, the 201-hp 2.0T with its 12V mild hybrid is smooth and hushed and the stop-start restart is barely felt; the 261-hp 45 TFSI adds enough low-rpm boost to mask most off-idle softness. Against that, reviewers and owners of 2023 cars still report delayed throttle and transmission responses off idle and abrupt engagement while creeping — the known wet-clutch DCT trait — which is what keeps this out of the 80s.

The 2.0T stays distant and inoffensive at a cruise and is well isolated through the controls, contributing directly to the 2023 A4's reputation for a very quiet cabin. It loses points for character rather than volume: the four turns coarse and thrashy near redline, and there is nothing to enjoy in the sound when you use the revs.

38.1 feet is wide for a 188-inch sedan — a direct consequence of the longitudinal engine layout pushing the front axle rearward and limiting steering lock. Unchanged for 2023, and the one everyday-drivability figure that works against the A4's otherwise compact footprint.

A genuine strength — a wide range of seat and tilt/telescoping wheel adjustment with standard power front seats, a low cowl with clear forward sightlines, and logically grouped controls let most drivers get well situated. Crucially for 2023, Audi kept a separate physical tri-zone climate panel below the display rather than burying temperature in the touchscreen. Ingress and egress are easy for a low sedan.

In volume 40 TFSI form the A4 is polished and satisfying without being something enthusiasts seek out: 201 hp and a low-six-second 0–60 give it no urgency, the steering withholds feedback, and the character is quiet competence rather than appetite. Buyers who want the entertaining version of this chassis step to the 261-hp 45 TFSI — which for 2023 gained standard 19-inch wheels on summer tires — or to the S4.

The base 40 TFSI Premium is well stocked for the class — quattro AWD and the 7-speed dual-clutch standard on every A4, a 10.1-inch MMI touchscreen with wireless Apple CarPlay and Android Auto, power sunroof, tri-zone climate, leather seating and heated front seats — and 2023 adds LED headlights with the DRL signature as standard across the A4 40, 45 and allroad, with Bang & Olufsen 3D audio becoming standard on Premium Plus. It sits above the chip-deleted 2022 car but below the 2024 A4, because adaptive cruise and lane-keeping were still options inside the Convenience package for 2023 rather than base equipment.

At $41,395 delivered with quattro standard, the 2023 A4 undercuts a rear-drive 330i and a 4MATIC C 300 by a meaningful margin for comparable content, and the 261-hp 45 TFSI S line at $42,400 before destination remains one of the segment's better power-per-dollar plays. The value case is real but not a bargain — the ladder escalates fast to a $52k S line Prestige, and Genesis G70 and Cadillac CT4 still hand over more equipment per dollar.

Six sedan configurations for 2023 — Premium, Premium Plus and Prestige each offered with the 201-hp 40 TFSI or the 261-hp 45 TFSI S line — spanning roughly $41k to $53k delivered, with the 349-hp S4 above them and the A4 allroad wagon alongside on the same platform. Wide and well-spaced; the real gaps are that quattro is mandatory (no cheaper front-drive entry) and the US A4 was gas-only, with no hybrid or plug-in the way BMW's 3 Series family offered.

2023 is where the A4's decline became unmistakable: about 13,550 US deliveries, down 11% from 2022, in a year when Audi's own US volume jumped 22% to 228,550 — so the sedan shrank while the brand around it grew. It finished well behind the Mercedes C-Class's 32,698 and further behind the 3 Series, and by then the A5 (23,777) was outselling it inside Audi's own showroom. A fading mid-pack seller, though not yet the 2024 collapse.

The four rings carry genuine aspirational pull in the US — design-led, tech-forward, with quattro as a real brand asset rather than a marketing word — and 2023 was a strong year for the brand, up 22% on the back of the Q5 and an expanding EV lineup. Audi still sits a step behind BMW and Mercedes on outright luxury cachet and on resale support in this segment, which is why this is a strong score rather than a top one.

2023 is the year the chip-shortage seller's market broke and the A4 buyer finally got something back: Audi Financial Services ran roughly $1,000 in lease bonus cash on 2023 A4 trims with subvented money factors and residuals in the low 60s, and inventory recovered enough that cars negotiated off sticker instead of at it. Modest and occasional rather than generous — well ahead of the $750-on-the-whole-line 2022 program, but a long way short of the ~$2,000 lease cash and cash-back events that came with the run-out 2024–25 cars.

2023 is the seventh model year of the B9 generation launched for 2017 and three years past its 2020 facelift — a late-mid-cycle car on a platform and MMI architecture that were no longer current. What separates it from 2022 is that the replacement went public during the model year: in March 2023 Audi's CEO confirmed the A4 would be renamed A5, so a buyer shopping the back half of 2023 knew the nameplate had an expiry date.

The 2023 A4 was the high-water mark of the late B9 run for critical standing: U.S. News scored it 8.5/10 and ranked it #1 in Luxury Small Cars, KBB gave it a 4.5/5 expert rating and #4 among 2023 luxury compacts, and Edmunds called it a worthy rival to the C-Class, 3 Series and S60. It still never won the class outright — no 10Best, no NACTOY, and the 3 Series takes it on driver engagement — but this is clearly stronger footing than the #5 ranking and 4.3 rating the nameplate had slipped to by 2024.
