2024 Audi A6

2024 is a C8-generation carry-over year with only cosmetic and equipment updates, and the US A6 sedan's volume configuration remains the 45 TFSI Premium — a 261 hp turbocharged 2.0L four with 12V mild-hybrid assist, standard on Premium and Premium Plus. The 335 hp 55 TFSI V6 is optional on those two trims and standard on Prestige, so 335 hp is the A6 range max (the 444 hp S6 is a separate nameplate).

The 2.0L TFSI makes 273 lb-ft from just 1,600 rpm, so the volume A6 feels stronger in everyday driving than the horsepower figure suggests, though the number itself is mid-pack for a mid-size luxury sedan.

The 45 TFSI quattro reaches 60 mph in about 5.8 seconds — quick enough to never feel underpowered, but slower than the V6 rivals and EVs that anchor the top of this segment's band.

The 2.0T itself is quiet and smooth at cruise with the mild-hybrid system smoothing stop-start, and torque arriving at 1,600 rpm keeps turbo lag modest. It loses ground to the segment's sixes on outright refinement — the four is audible under hard throttle and the drivetrain hesitates off the line, which reviewers attribute mainly to the dual-clutch rather than the engine.

The seven-speed S tronic dual-clutch shifts crisply and picks sensible gears once underway, but its low-speed manners are a documented weak point: Consumer Reports calls it short on refinement at low speeds with hesitation before launch and from a rolling stop. That is a real, repeatable annoyance in traffic, so it sits in the middle band rather than the top.

Every 2024 US A6 is a quattro — there is no front- or rear-drive version at any trim or engine. The system is Audi's mature permanent all-wheel drive with wheel-selective torque control, and a sport differential is available on the V6, though there is no low range or terrain-mode hardware to reach the very top of the band.

The 2024 A6 sedan offers two genuinely distinct gas powertrains — the 261 hp 2.0T four and the 335 hp 3.0T V6 — covering mainstream and performance-leaning buyers, with the S6 above it for anyone wanting more. But there is no hybrid, plug-in hybrid or battery-electric A6 sedan in the US for 2024, which is where rivals separate: the BMW 5 Series fields a 530e plug-in and an i5 EV and the E-Class a mild-hybrid inline-six. Two choices, both conventional gas, places this in the middle band.

EPA rates the volume 2024 A6 45 TFSI quattro at 26 MPG combined — a respectable figure for a 4,100 lb standard-AWD luxury sedan with a 12V mild hybrid, but unremarkable against the gas-sedan band as a whole and far behind the hybrid luxury sedans it competes with.

23 MPG city is the weakest part of the A6's economy profile: the 12V mild-hybrid system extends stop-start and coasting but cannot move the car on electricity, so urban driving gets no meaningful electrified assistance and permanent quattro adds parasitic loss.

33 MPG highway is the A6's best efficiency showing — the C8 body is slippery, the seventh gear is tall, and the 2.0T is lightly loaded at cruise, so the car is genuinely economical on a road trip even with standard all-wheel drive.

The EPA's own total-range figure for the 45 TFSI is 502 miles on a 19.3-gallon tank — solid long-distance capability that is the strongest element of this category and partly offsets the modest MPG and expensive fuel.

The EPA puts annual fuel spend at $2,900 — near the top of the sedan band's cost range despite mid-pack MPG, because 26 MPG combined is multiplied by a premium-grade reference price. The fuel requirement, not the consumption, is what makes this expensive to run.

Both A6 engines take premium unleaded, and the EPA classifies the car as premium-gasoline fuelled — a surcharge of roughly 40–60¢ per gallon over regular that the owner cannot avoid. With no diesel, flex-fuel, hybrid or plug-in variant offered on the 2024 US A6 sedan, there is no configuration that lowers the energy bill.

NHTSA tested the 2024 A6 Sedan 4DR AWD and awarded the full five-star overall rating. The one soft spot is the frontal composite at 4 stars — driver side 5, passenger side 4 — while side impact (barrier and pole) and rollover are both 5.

Every crashworthiness result IIHS holds for the C8 A6 is Good — small overlap front on both sides and the original moderate overlap test — but the coverage is thin and there is no award. The 2024 A6 sedan does not appear on the 2024 Top Safety Pick list at all, and IIHS has never published a side impact, roof strength, head restraint or updated moderate overlap result for this car, so the rear-passenger and side protection the current criteria are built around are simply unmeasured.

The volume 45 TFSI Premium Plus ($60,800) carries the full suite standard, but the entry Premium leaves the three items buyers actually shop for — adaptive cruise assist, Audi side assist blind-spot monitoring with rear cross-traffic, and the top-view camera — inside a $2,250 Convenience Package. What is genuinely standard across the range is Audi pre sense front AEB with pedestrian detection, active lane assist (lane departure warning and prevention), high-beam assist, ten airbags, and front and rear parking sensors newly standardized for 2024.

Audi pre sense front earns IIHS's top Superior rating in the pedestrian front crash prevention test, avoiding the crossing adult at 12 mph, the crossing child at 25 mph and the parallel adult at 25 mph outright. It is held out of the top band because the evaluation is daytime-only — IIHS has no nighttime pedestrian result for this car, and no vehicle-to-vehicle front crash prevention rating is published for the 2024 A6 either.

Audi side assist bundles mirror-mounted blind-spot warning with rear cross-traffic alert and pre sense rear with vehicle exit warning, and reviewers rate the system as working well. Coverage stays mid-band because it is alert-only on the volume car — rear automatic braking is the optional intervention layer — and because the entry Premium has to buy the Convenience Package to get any of it.

Active lane assist — lane departure warning plus corrective prevention — is standard on every 2024 A6, and the lane-guidance centering that comes with adaptive cruise assist tracks steadily enough on marked highway that reviewers do not complain of wander in the C8, unlike its C9 successor. It sits mid-70s rather than higher because true centering is a Premium Plus feature and the system needs clear markings to engage.

Adaptive cruise assist is a full-speed-range system with stop-and-go that fuses radar, camera and ultrasonic input and combines distance keeping with lane guidance; Edmunds reports the adaptive cruise works well on this generation, and 2024 adds a new adaptive cruise assist display in the virtual cockpit. It falls short of the top band because it is a $2,250 option on the entry Premium rather than standard equipment across the line.

Audi offers no hands-free highway system on the 2024 A6 in the US — there is no BlueCruise, Super Cruise or comparable equivalent. Adaptive cruise assist tolerates only brief hands-off intervals of roughly 15 seconds in slow traffic before nagging, which is a hands-on system's grace period rather than a hands-free mode.

IIHS rates both headlight systems available on the 2024 A6 Good — there is no Acceptable or Marginal variant anywhere in the range, so the volume buyer gets the best lighting the car offers — and high-beam assist is standard on both. Held just under the ceiling because neither system is curve-adaptive.

Side and rear-quarter glass are generous for the class and the forward view is rated good overall, but thick front pillars intrude and the short, steeply raked rear window pushes the driver onto the standard rearview camera. Front and rear parking sensors became standard for 2024 which helps at low speed, though the top-view 360 camera that would fully compensate is a Premium Plus feature.

IIHS gives the A6's LATCH hardware its top Good rating for ease of use, with two outboard positions carrying complete lower-anchor plus tether hardware and a third center position offering a tether anchor, all of which can be reached with the seatback properly positioned. The mid-size sedan bench still makes three car seats across impractical, which is what keeps it off the very top of the band.

The 2024 A6 is a C8-generation carry-over that seats five in every US trim and engine combination; there is no four-seat or executive-rear configuration in this market. The centre rear position sits over a tall transmission tunnel — quattro is standard on every 2024 A6 — so in practice it is a short-trip seat.

38.0 in of front headroom is exactly mid-band for a sedan and unchanged for 2024, whose updates were cosmetic (new grille, rear diffuser, standard Matrix-design LED headlights, new wheels and inlays) rather than structural. Because the power panoramic sunroof is standard equipment on all three trims, this is the figure every buyer actually gets.

41.3 in sits in the lower third of the mid-size sedan band — a long-standing Audi packaging trait that carries unchanged through the C8's run and into the 2026 C9, which publishes the identical figure. Reviewers still describe the front cabin as airy and spacious, so the number understates how it feels, but seat travel is merely adequate rather than generous for a very tall driver.

38.1 in of rear headroom is in the upper part of the sedan band and, unusually, a tenth more than the front measurement — the C8's roofline holds its height over the second row before the tail drops away. It clears six-footers in back comfortably and is the strongest of the A6's five passenger-space dimensions.

37.4 in on a 115.1 in wheelbase is mid-pack: adults sit properly for commutes and medium trips, but the A6 does not offer the rear sprawl of a Genesis G80 or a long-wheelbase E-Class, and there is no extended-wheelbase A6 in the US. Consumer Reports' 2024 road test nonetheless rates the rear seat comfortable and supportive.

13.7 cu ft is a little below the mid-size sedan average and is the practical ceiling on the A6's family and road-trip missions — two large suitcases plus soft bags rather than four. A 40/20/40 split-folding seatback with a centre pass-through in the armrest extends it for skis and other long items, but the sedan aperture limits bulky loads.

Competent and conventional rather than clever: usefully deep door bins, a lidded console cubby, a covered front tray housing the Audi phone box wireless charger on trims that get one, a decent glovebox, and a 40/20/40 rear seatback with a centre pass-through. There is no standout innovation — no underfloor bin, no reconfigurable console, no onboard household power — and the 8.6-inch lower climate screen occupies console real estate that some rivals give over to storage.

Directly corroborated by an instrumented road test: Consumer Reports calls the 2024 A6's seats extremely comfortable and supportive, and rates both rows fit for long trips. Eight-way power heated leather front seats are standard on the base Premium, and the volume Premium Plus adds ventilated fronts, so the seats a typical buyer gets are well equipped as well as well shaped; massaging fronts are a Prestige Luxury Package item.

Composed but firm, and Consumer Reports names the ride as one of the two specific reasons the A6 misses top honours in its class. The body stays steady and the suspension absorbs big impacts well, but road texture reaches the cabin on the standard steel-spring setup that the volume Premium and Premium Plus ride on. Adaptive air suspension transforms it and is genuinely plush, but it is an option most buyers do not take.

Consumer Reports calls the cabin quiet outright and it is one of the car's stated strengths — wind and road noise are well suppressed by the C8 shell, and the 2024 Executive Package now adds dual-pane acoustic glass. What holds it below the top band is the volume 45 TFSI's four-cylinder, which is audible under load and less polished than the optional V6.

A rich standard set even at the entry point: heated eight-way power front seats, leather, three-zone automatic climate, a power panoramic sunroof, a power trunk lid, a power-adjustable steering column and ambient lighting are standard on every 2024 A6, and Premium Plus and above gain the contoured multi-colour ambient LED package newly standardised for 2024. Ventilated front seats, heated rear seats, a heated steering wheel and four-zone climate all cost a trim step or a package, which is what keeps it out of the top band.

The 2024 A6 opens at $57,300 for the Premium 45 TFSI quattro plus $1,095 destination. That is well above the sedan band ceiling, though the A6 undercuts the 2024 BMW 530i xDrive ($61,195) and Mercedes E 350 ($63,450) while including quattro AWD as standard.

The volume 2024 A6 is the 45 TFSI (261 hp 2.0T) in Premium trim, and few leave the lot stripped — the $2,250 Convenience Package carries the adaptive cruise assist, side assist and top-view camera that the Premium does not include, and metallic paint adds roughly $595, putting typical transactions near $61,200. Stepping up to the Premium Plus 45 TFSI ($60,800 + destination = $61,895) lands in the same place.

CarEdge projects $3,228 of maintenance and repair over five years for the A6 ($646/yr), and the 4yr/50k bumper-to-bumper warranty absorbs most repairs inside the window. Set materially above that baseline because MY2024 predates Audi Signature Care: every scheduled service is owner-paid, and Audi Care — the prepaid plan that covers 10,000 to 40,000 miles — runs roughly $1,000–$1,400 on its own, on top of German dealer labor rates.

The observed market for this exact car is harsh: two years in, a 2024 A6 averages about $31,000 used against a roughly $61,200 as-equipped price — barely half retained — because it is an outgoing C8 that sold on very heavy incentives against all-new rivals. iSeeCars measures 55.6% five-year depreciation for the A6 (44.4% retained) versus 46.4% for the luxury midsize class; CarEdge's generic 51% projection is generation-blind and reads optimistic here, so 40% sits between the observed trajectory and the published estimates.

Standard Audi New Vehicle Limited Warranty for 2024. Matches BMW and Mercedes at 4/50 and beats the 4/50 segment floor only by tying it; Genesis (5/60) covers the G80 buyer longer.

Audi has offered no separate longer powertrain warranty since MY2020, so powertrain coverage on the 2024 A6 expires with the 4/50 basic. That is below the bottom of the 5–10 year scoring band and far short of Genesis's 10-year/100,000-mile powertrain coverage — the A6's weakest ownership metric, and it matters more here than on a cheaper car given the 2.0T's dual-clutch transmission.

MY2024 gets no complimentary scheduled maintenance at all — Audi Care is a prepaid plan the buyer purchases, and the Signature Care program that made service free to 3yr/30k did not arrive until MY2026. What is included is roadside assistance for the full 4-year warranty term, 12-year corrosion coverage, and a six-month Audi connect PLUS trial newly standard for 2024. That is basic roadside plus a short connected-services trial and nothing more, which sits at the top of the no-complimentary-coverage band rather than in the included-maintenance band.

$61,200 volume-trim price minus its estimated resale value after 5 years (40% retained, or about $24,480) leaves about $36,720 in depreciation. Add the projected $4,600 in 5-year maintenance and repairs, and owning this vehicle for 5 years costs about $41,320 in total.

Consumer Reports is explicitly negative on this model year — it calls the 2024 A6 less reliable than other cars from the same model year, a step down from the about-average call it gives the 2025 car — and its own per-area trouble-spot chart is all NA, meaning the verdict rests on the deteriorating Audi brand data rather than A6-specific survey returns. Held just above the below-average band because the C8 is a mature design six years into field service by 2024 and RepairPal's nameplate data is near-average, so the signals are mixed rather than uniformly bad.

Audi's standing in the studies contemporaneous with this model year is bottom-third on both measures, and the three-year dependability gap is the widest of the German three by a large margin: 275 PP100 against a 190 industry average, second-to-last of all brands and behind Land Rover. Initial quality is only marginally better — second-to-last again, tied with Volvo and ahead of only Dodge. Infotainment and connectivity dominate the industry problem mix rather than mechanical failure, which is the only thing keeping this off the floor of the band.

The 2024 model year itself carries a light campaign record — a single NHTSA recall, and that one is a software error in the rearview camera display remedied by a free dealer software update, with nothing touching powertrain, structure or fire risk. Kept out of the top band because the C8 generation as a whole has a substantial multi-campaign history and because the one recall the 2024 car does have is the same software/electronics theme that runs through the generation's complaint profile and Audi's IQS deficit — a pattern, not an isolated slip.

The volume 45 TFSI pairs the 2.0L EA888 turbo four (261 hp) with the DL382 7-speed S tronic wet-clutch dual-clutch transmission and a 12V belt-driven starter-generator mild hybrid — long-serving VW Group hardware with a high-mileage track record and no systemic failure pattern, and unchanged for 2024, which was a cosmetic refresh rather than a powertrain change year. Discounted from the top band for well-documented maintenance liabilities rather than fragility: direct-injection carbon buildup requiring periodic walnut blasting, water pump/thermostat replacement, and the belt starter generator as an added failure point.

Material richness is the A6's clearest strength and reviewers of this specific model year are close to unanimous: soft leather standard even on the base car, genuine wood and nickel-finish metal trim, and soft-touch coverage described as flawless — with 2024 adding standard multi-colour ambient LED lighting from Premium Plus up and folding dual-pane acoustic glass into the Executive package. Kept just below the top of the band because the C8 cabin design is aging against newer rivals and the twin haptic touchscreens are persistent fingerprint magnets.

Physical assembly is genuinely good — reviewers of the 2024 car call out top-notch build quality and a quiet, rattle-free cabin from the Neckarsulm line — but this item's guidance names initial-quality reports explicitly, and Audi finished second-to-last of all brands in the 2024 IQS at 48 PP100 worse than industry average. Because that deficit is concentrated in infotainment and controls rather than build defects, the item sits in the upper-middle band instead of collapsing toward the brand score.

Audi's US retail network is the smallest of the German three — a bit over 300 stores against roughly 350 BMW centers and 386 Mercedes-Benz dealerships — which leaves thinner coverage outside metro areas for a car whose problem profile is software-heavy and therefore dealer-dependent. Service satisfaction is adequate rather than distinguishing: Audi does not appear among the premium leaders in J.D. Power's 2024 Customer Service Index, and a 14% US sales decline in 2024 puts the network under commercial pressure rather than expanding it.

Running costs are typical for a German luxury sedan — below the luxury-class average but well above the all-vehicle average — and parts are European-premium priced with diagnostics and software work channelled through the dealer. Notably, the quattro configuration that every US A6 uses costs meaningfully more to run than the nameplate average, and the mild-hybrid belt starter generator, dual-clutch service and haptic-screen electronics are all dealer-cost items; reasonable C8 aftermarket support keeps this in the lower half of the normal band rather than the bottom one.

Every 2024 A6 gets the same 10.1-inch haptic MMI touch response display — there is no larger option — with a separate 8.6-inch lower screen handling climate and comfort settings. The framework measures the centre display, and 10.1 in is modest for 2024: it is the same panel the C8 launched with in 2019 and less than half the area of the 14.5-inch OLED the 2026 C9 replaced it with.

Consumer Reports rates the system easy to use and it is genuinely quick, with reconfigurable home-screen tiles, crisp graphics and haptic feedback that confirms every press. The demerits are structural rather than software: the C8 deleted the old MMI rotary controller, so climate and seat heating live on the lower touchscreen and demand a look away from the road, and both glossy panels are fingerprint magnets. Solid upper-middle rather than best-in-class.

Audi smartphone interface with Apple CarPlay and Android Auto is standard on every 2024 A6 including the base Premium, and both connect wirelessly — Audi added wireless Android Auto alongside wireless CarPlay across the MIB3 range from the 2022 model year, which covers the C8 A6. Held just below the ceiling because Audi does not publish a US trim-by-trim wireless confirmation, and a USB-C cable is still needed for the highest-bandwidth functions.

MMI navigation plus with cloud-assisted mapping, live traffic and onboard Wi-Fi is standard on every trim, not a package item — unusual at this price — and the natural-language voice assistant handles conversational destination and climate requests, with Amazon Alexa built in through the MIB3 platform. It is a step behind the best natural-language systems on free-form queries, which is why owners still reach for phone projection for search.

The upgrade path is a genuine strength: the volume Premium Plus gets the 16-speaker Bang & Olufsen 3D Premium Sound System as standard equipment, and a 19-speaker, 16-channel, 755-watt B&O 3D Advanced system is available above it — one of the better factory systems on sale at any price. The base Premium's ten-speaker system is merely adequate, which is the only thing holding this off the top of the band.

The 12.3-inch Audi virtual cockpit plus is standard on the base Premium, not an upsell — a crisp, high-refresh full-digital cluster with classic, sport and full-screen Google Earth map views switchable from the steering wheel, and for 2024 a new adaptive cruise assist display when that system is fitted. It is one of the best clusters in the class and its near-universal availability is the point; only the newer 11.9-inch OLED panel in the C9 betters it.

The C8's over-the-air capability is infotainment-scoped, not whole-vehicle: navigation map data and MMI/app-store content update over the air, and 2024 expanded that meaningfully by adding the Audi app store and a six-month Audi connect PLUS trial to every A6, but drivetrain, chassis and ADAS control modules still require a dealer flash. That is the middle band by definition — real OTA, but maps and infotainment only.

2024 is the year the myAudi app got materially better on this car: remote engine start became standard across the line through Audi connect, joining remote lock/unlock, vehicle locator, status checks and destination send-to-car, with the baseline Audi connect CARE package free for years rather than months. It stays mid-band because remote start is app-only — there is no fob button — the richer functions ride on a paid Audi connect PLUS subscription after the six-month trial, and the C8 A6 offers no phone-as-key digital key.

USB-C data/charge ports front and rear are standard and the console tray takes the Audi phone box wireless charger — standard on Premium Plus and Prestige, optional on the base Premium. Competitive rather than generous: there is no household AC outlet, the wireless pad is a single position, and rear-seat charging is USB-C only with no dedicated high-output socket.

Keyless entry with push-button start and a power trunk lid are standard on every 2024 A6, and remote start via the myAudi app became standard for 2024 — a real gain over 2023. Power soft-closing doors are a Prestige feature. It falls short of the top band because Audi offers no phone-as-key or digital key on the C8 A6, and remote start depends on an Audi connect subscription and cell coverage rather than a fob.

Strong once you are past the base trim: a rearview camera and front and rear parking sensors are standard on every 2024 A6, and the top view camera system with Virtual 360 view — a high-resolution surround view with rotatable 3D perspectives — is standard on Premium Plus and Prestige, with Prestige adding remote parking assist plus for driverless perpendicular and parallel manoeuvres. Held below the top band because the entry Premium has to buy the $2,250 Convenience Package to get the 360 camera at all.

The A6 offers a good colour head-up display projecting speed, navigation and driver-assist status into the driver's sightline, but it is standard on the Prestige only and is not orderable on the volume trims — the buyer of a $58,100 Premium or a $62,600 Premium Plus cannot have one at any price. Available but locked to the $70,900 flagship is the definition of the middle band.

The hardware is genuinely good — IIHS rates the A6's LATCH provision Good, with two outboard positions carrying complete lower-anchor plus tether hardware and a third tether-only centre position, all reachable with the seatback properly placed. What caps it is body type: 37.4 in of rear legroom means a rear-facing seat crowds the front passenger, the tall quattro transmission tunnel makes the centre position a poor third seat, and a 13.7 cu ft trunk swallows one stroller plus groceries rather than a full family load.

The crash credentials are strong — a full five-star NHTSA overall rating, every IIHS crashworthiness result Good, Good-rated headlights on both available systems, and a Superior daytime pedestrian AEB result. The gap is what families have to pay for: the entry Premium ships with AEB, active lane assist and ten airbags but leaves blind-spot monitoring with rear cross-traffic alert, adaptive cruise assist and the 360 camera inside a $2,250 Convenience Package, and the A6 is absent from the 2024 IIHS Top Safety Pick list.

Four people travel very well: Consumer Reports rates the seats extremely comfortable and supportive and the cabin quiet, three-zone climate is standard with rear vents, and the EPA credits 502 miles of range so fuel stops are rare. Rear amenities are where it thins out — heated rear seats and four-zone climate are Premium Plus and Executive Package items, there is no rear-seat entertainment on the C8 A6, and 13.7 cu ft of trunk with four aboard is the real constraint on a week-long trip.

A relaxing commuter in most respects — quiet, comfortable, light-effort controls, standard quattro traction, and adaptive cruise assist with stop-and-go on the trims that carry it. One documented flaw keeps it out of the top band and Consumer Reports names it explicitly: the seven-speed dual-clutch's low-speed manners, with a hesitation before launch and from a rolling stop that repeats every time you creep in traffic.

Expensive per mile for a four-cylinder sedan. The EPA puts annual fuel spend at $2,900 on 26 MPG combined, and the multiplier is premium unleaded, which every 2024 A6 requires with no hybrid, PHEV or EV variant available to escape it. Consumables follow the same pattern — 19-inch (or 20-inch on Sport Package cars) performance rubber and Audi-schedule service on a mild-hybrid quattro drivetrain.

The A6 needs help in tight spaces and mostly gets it: front and rear parking sensors and a rearview camera are standard, the Virtual 360 top-view camera arrives on Premium Plus, and Prestige adds remote parking assist plus. But the underlying geometry is poor — a 39.7 ft turning circle is at the wide end of the sedan band, the US car cannot be optioned with the all-wheel steering that would shrink it, and thick A-pillars plus a short, steeply raked rear window force reliance on the screens.

Audi publishes no towing rating for the A6 sedan in the United States and offers no factory hitch for it, so the only work capacity is a 13.7 cu ft trunk reached through a sedan aperture. The 261 hp 2.0T pulls the car itself well, but there is nothing here for hauling, towing or carrying trade materials.

A luxury sedan built for refinement, not abuse: leather upholstery and two glossy touchscreens throughout, a dual-clutch transmission with a documented low-speed weak point, air suspension and 48V mild-hybrid hardware on optioned cars, and out-of-warranty repair costs to match. There is no fleet or commercial version of the A6 and no wear-friendly interior option.

Essentially nothing here. No onboard household power or inverter appears anywhere in the 2024 A6 option list, there is no bed, no factory hitch, no roof rails on the sedan body, and no washable surfaces — the trunk has a 12V socket and tie-downs and that is the extent of the work provision.

This is the A6's strongest mission. Consumer Reports rates the seats extremely comfortable and supportive and the cabin quiet, the EPA credits 502 miles of combined range — around 637 at the 33 MPG highway rating — and adaptive cruise assist with lane guidance takes the strain out of interstate miles on the trims that carry it. The firm standard suspension over broken pavement and the four-cylinder's voice under load are what stop it reaching the top of the band.

Standard quattro is a real asset — every 2024 A6 has permanent all-wheel drive with wheel-selective torque control, and it will handle a snowy pass or a gravel forest road with confidence. Everything else works against it: sedan ride height with no raised or off-road variant (that is the allroad wagon's job), no US tow rating for a bike or utility trailer, no factory roof rails, no trunk power outlet beyond 12V, and a sedan trunk instead of a flat-folding load bay.

Restrictive for bulky items. 13.7 cu ft is below the mid-size sedan average, and the 40/20/40 split-folding seatback with a centre pass-through — genuinely useful for skis or lumber — still opens into a sedan trunk with a narrow aperture and a high lip rather than a hatch. With no roof rails and no hitch, there is no way to add capacity outside the car either.

Consumer Reports' 2024 road test calls the handling lively and sporty, and the C8's limits are genuinely high for a 4,100 lb car — standard quattro with wheel-selective torque control gives it the grip to hold long sweepers and change direction cleanly. The reservation reviewers consistently return to is engagement rather than capability: it is quick and composed through a good road without ever feeling fully involving, which is where the 3 Series and G70 pull ahead.

Accurate and well weighted — Consumer Reports describes it as sharp and says it brings the driver into the action, and it tracks straight and true at highway speed with no wander. It is precise rather than communicative, though: the electric rack filters out most surface texture, which is the standard Audi criticism and keeps this in the upper-middle band rather than at the top.

The clear strength of the A6's dynamic repertoire: Consumer Reports singles out the braking as superb and credits it with adding control and confidence, and Edmunds' instrumented test of a C8 A6 recorded a 103 ft stop from 60 mph — sports-car territory for a car of this mass. Held just below the ceiling because that test car ran summer tires; the all-season rubber most 2024 A6s wear will stop meaningfully longer.

Split character. Once moving, the 45 TFSI is smooth and strong — 273 lb-ft from 1,600 rpm, tidy 5.8 s to 60, and a 12V mild-hybrid system that makes the stop-start restarts almost imperceptible. Below walking pace it is the weakest part of the car: Consumer Reports states plainly that the seven-speed dual-clutch is short on refinement at low speeds and that the car hesitates before launch and from a rolling stop, a flaw repeated every time you pull into traffic.

At cruise the drivetrain effectively disappears into a cabin Consumer Reports calls quiet, and there is no vibration through the wheel or pedals. Under load the four-cylinder's character is the limit — CR notes the 2.0T's sound is noticeable and less polished than the optional V6's, which is what separates the volume A6 from the sixes and inline-sixes that define the top of this segment.

39.7 ft is at the wide end of the sedan band and the A6's clear everyday-drivability weakness — three-point turns become five-point turns in a tight garage. The dynamic all-wheel steering that shrinks the C8's circle to about 11.1 m (36.4 ft) is not offered on the US A6, so 39.7 ft is what every 2024 buyer gets; the 2026 C9 is wider still at 40.4 ft without its optional rear steer.

A well-judged place to sit: eight-way power front seats and a power-adjustable steering column are standard on every trim, so drivers of most sizes find a good relationship to the wheel and pedals, and the 12.3-inch virtual cockpit puts the primary information directly ahead. Two things hold it back — thick A-pillars that intrude on the forward view, and the low-mounted 8.6-inch climate screen, which moves heater and seat-heating controls off the dash and demands a look down.

Satisfying without being memorable. The A6 is quick, grippy and beautifully damped in its responses, and reviewers acknowledge it turns sporty when pushed — but the four-cylinder soundtrack, the dual-clutch's low-speed reluctance and the deliberate isolation add up to a car that impresses rather than entertains. Enthusiasts in this segment point to the 3 Series or the S6 rather than a 45 TFSI A6.

The Premium 45 TFSI is well furnished for $58,395 delivered: quattro AWD, 19-inch wheels, S line exterior, leather, heated power front seats with memory, tri-zone climate, panoramic sunroof, navigation with wireless CarPlay/Android Auto, the 12.3-inch virtual cockpit plus and the dual-touchscreen MMI — and for 2024 Matrix-design LED headlights became standard across the range. Held out of the top band because the driver-assist content most buyers expect is not included: adaptive cruise assist, side assist/blind-spot and the top-view camera all live in a $2,250 Convenience Package, and ventilated seats and B&O audio require moving up the range.

On sticker the A6 argues well — $58,395 with quattro standard undercuts a 2024 530i xDrive ($61,195) and an E 350 ($63,450), both of which also make do with roughly 255 hp, and Audi's transaction prices were far below sticker on a run-out generation. Against that, the Genesis G80 2.5T AWD starts at $55,560 with more standard content and a longer warranty, the A6 is the oldest architecture in the group by five years, and US News rates its value below average for the class — fair value rather than a bargain.

Two engines and three trims give the 2024 US A6 real spread — the 261 hp 45 TFSI on Premium and Premium Plus, the 335 hp 55 TFSI V6 on all three, from $58,395 to about $72,000 delivered, with Convenience, Executive, Premium Plus and Black Optic Sport packages to fill the gaps. Notably broader than the V6-only 2026 car. Marked down because everything is quattro sedan: no rear-drive option, no wagon under this nameplate in the US (the allroad is a separate model line), and no plug-in or electric variant.

The A6 is a niche seller in a shrinking segment: 8,519 US units in calendar 2024, up 2% on 2023 but only about a third of the BMW 5 Series' 25,315, which grew 13% in the same year on the back of an all-new generation. The A6 also held its ground while Audi's US volume fell 14% overall, so acceptance is stable rather than collapsing — but this is a slow seller by segment standards.

Audi is a genuinely aspirational premium brand with quattro as durable equity and a design-led interior reputation, and the A6 sits toward the senior end of the range. Trimmed below the 2026 car's mark because 2024 was a visibly weak year for the brand in the US — volume down 14% while BMW set a record — and that momentum gap is precisely what shows up later in the A6's resale performance.

For a buyer, the 2024 A6 was one of the best-discounted cars in the segment: Audi Financial Services ran a $7,500 customer bonus on the A6 45 and $5,000 on the A6 55, with subvented APR as low as 0.99%/60 months on select 2024 models, and advertised leases capitalized roughly $11,700 below sticker. Scored on buyer benefit as the item directs; the caveat is that this generosity is the run-out of an outgoing generation and is the same force driving the car's steep depreciation.

2024 is year six of the C8 generation that launched for MY2019, and it is the mid-cycle equipment update rather than a new car: standard Matrix-design LED headlights, revised grille and wheel designs, optional dual-pane acoustic side glass on Premium Plus, and a six-month Audi connect PLUS trial. The timing is unkind — 2024 is the year both the BMW 5 Series (G60) and Mercedes E-Class (W214) arrived all-new — and the C9 replacement was already visible on the horizon, reaching the US for 2026.

Reviewers still liked the car — US News scores the 2024 A6 8.9/10 as a 'great luxury midsize car' with a polished, upscale interior, and Edmunds owners average 4.0/5 — but it collected no major hardware for 2024. It is absent from the IIHS 2024 Top Safety Pick list (the Audi entries that year are the Q4 e-tron, Q4 Sportback e-tron, Q7, Q8 and the Q8 e-trons), took no 10Best or NACTOY nod, and was routinely placed behind the newly redesigned 5 Series and E-Class in the year's comparisons, with US News flagging below-average value for the class.
