The 2024 Audi A8 is available as a one-year-old used luxury sedan for approximately $53,000 to $80,000, offering 335 horsepower from its mild-hybrid V6 and standard quattro all-wheel drive. While it delivers traditional Audi refinement and comfort, buyers should be aware of its 5/10 reliability rating and potential for high maintenance costs averaging $10,258 over a decade.
The 2024 A8 presents an interesting value proposition in the used luxury market. According to Autvex market analysis, one-year-old luxury flagships typically depreciate 20-30% from their original MSRP, making them attractive for buyers who want premium features without the new-car premium[1]. The A8's position as a carryover model actually benefits used buyers—the bugs have been worked out over years of production.
However, this same maturity works against the A8 when compared to fresher rivals. The car's fundamental design dates back to 2017, making it feel dated against the all-new 2024 BMW 7 Series and Mercedes-Benz S-Class that underwent complete redesigns recently[2].
The answer depends on your priorities. For traditional luxury buyers seeking comfort and refinement at a discount, the 2024 A8 makes sense. J.D. Power predicts average reliability comparable to other luxury sedans, while the proven platform means fewer unexpected surprises[3]. The standard quattro all-wheel drive adds confidence in various weather conditions.
Yet concerns exist. Consumer feedback reveals a 5/10 reliability rating from some sources, with common issues including complex air suspension failures and electrical gremlins[4]. These problems can translate into expensive repairs once the warranty expires, making extended coverage worth considering.
The D5 generation represents Audi's longest-running A8 platform, now in its eighth year. This extended production run brings both benefits and drawbacks for used buyers. Positively, technicians understand the platform thoroughly, parts availability remains strong, and most early production issues have been resolved[5].
The architecture supports Audi's MLB Evo platform, enabling the integration of mild-hybrid technology and advanced driver assistance systems. While not cutting-edge, these features provide adequate functionality for daily luxury driving. The platform's maturity means most Audi dealers can service it competently, unlike newer, more complex systems.
As a carryover model, the 2024 A8 received minimal updates from 2023. The most significant change involved app-based remote start functionality through Audi Connect PLUS, allowing owners to pre-condition their vehicles from smartphones[2]. This feature proves particularly valuable in extreme weather climates.
The carryover status means buyers get essentially the same car as 2023 models, potentially at lower prices. This stability helps with parts availability and repair knowledge but also means missing out on the latest safety and technology features found in redesigned competitors.
The used market for 2024 A8 models shows significant variation based on condition, mileage, and equipment. Understanding these price ranges helps buyers identify good deals versus overpriced examples. According to [Autvex's used car guidelines], luxury sedans with under 15,000 annual miles represent better long-term investments.
Dealer retail prices typically run higher than private party sales, but include benefits like inspection processes and potential warranty coverage. The sweet spot appears to be clean-condition examples with moderate mileage around $54,000-$58,000[6].
Current market data reveals the following price structure for 2024 A8 models:
| Condition | Price Range | Typical Mileage |
|---|---|---|
| Rough | $52,649 | 25,000+ miles |
| Average | $53,889 - $54,843 | 15,000-25,000 miles |
| Clean | $54,843 - $58,470 | 10,000-15,000 miles |
| Excellent/Low Miles | Up to $80,000 | Under 10,000 miles |
These prices reflect dealer retail values. Private party sales typically run 5-10% lower, though buyers sacrifice dealer protections and financing options[6].
The 2024 A8's original MSRP started at approximately $91,000 for the base model, with typical transaction prices slightly lower due to dealer incentives[2]. Fully equipped examples with Executive packages could exceed $110,000. This means current used prices represent 40-45% depreciation in just one year.
High-performance S8 models originally started around $125,000, making their current used values particularly attractive for performance-oriented buyers. These models now trade between $75,000-$95,000 depending on mileage and condition.
Looking forward, the A8's value trajectory depends on several factors. The impending arrival of the electric A8 e-tron could accelerate depreciation of gas models, though this remains uncertain[7]. Conversely, if Audi delays the electric transition, current gas models might hold value better as the last of their kind.
Edmunds' appraisal data suggests steady but moderate depreciation continuing through 2025, with clean examples maintaining values around $50,000-$55,000 by year-end[6]. This represents reasonable value retention for the luxury segment.
First-year depreciation hit the 2024 A8 particularly hard due to its carryover status. While typical luxury sedans lose 20-25% in year one, the A8's outdated design pushed depreciation closer to 40%[1]. This aggressive depreciation actually benefits used buyers who can access near-new vehicles at substantial discounts.
Future depreciation should slow to more typical rates of 10-15% annually. The car's complexity and potential repair costs will influence resale values, making maintenance history increasingly important for value retention.
For buyers prioritizing immediate luxury at a discount, the 2024 A8 offers compelling value. You get Audi's build quality, refined powertrains, and comprehensive features for roughly half the original price[7]. The standard equipment list remains impressive, including features many rivals charge extra for.
However, factor in ownership costs beyond purchase price. Annual maintenance averages $1,025, with major services potentially exceeding $2,000. Extended warranty coverage adds $2,000-$4,000 but could prevent single repairs from exceeding that cost. Consider these expenses when evaluating total value proposition.
Reliability represents the most critical consideration for used luxury sedan buyers. The 2024 A8's complex technology and aging platform create a mixed reliability picture. According to Autvex reliability data, German luxury sedans generally require more maintenance than Japanese alternatives but offer superior driving experiences when properly maintained.
Understanding common failure points helps buyers inspect potential purchases more effectively and budget for future repairs. Pre-purchase inspections by Audi specialists prove essential given the car's complexity[8].
Multiple sources provide varying reliability assessments. J.D. Power predicts average reliability based on similar Audi models, while The Car Guide assigns a concerning 5/10 rating[3]. Consumer Reports data remains limited for the 2024 model year, though previous years showed mixed results.
Real-world owner experiences on Edmunds average 4.1 out of 5 stars, suggesting satisfied owners despite potential issues[9]. This disconnect between professional ratings and owner satisfaction often occurs with luxury vehicles where buyers expect and accept higher maintenance requirements.
Based on A8 generation history and early 2024 reports, several issues warrant attention:
The D5 generation's extended production run reveals patterns in long-term reliability. Years 2017-2019 showed more issues as Audi worked through initial production problems. By 2020, most significant concerns were addressed, making 2024 models among the most refined[5].
Common wear items for the generation include brake components (expensive due to size and performance requirements), transmission servicing needs, and potential coolant system repairs. Budget $2,000-$3,000 annually for maintenance and minor repairs on higher-mileage examples.
J.D. Power's predicted reliability score places the 2024 A8 at average for luxury sedans, neither exceptional nor problematic[3]. This middling score reflects the car's mature platform—fewer surprises but also dated technology that occasionally acts up.
The Vehicle Dependability Study considers long-term ownership experiences, where the A8 performs adequately. Owners report satisfaction with dealer service experiences, though costs remain high. Compared to other Audi sedans, the A8's complexity increases repair frequency and expense.
As of late 2024, no major recalls affect the 2024 A8 specifically. However, buyers should verify recall status through NHTSA's database using the vehicle's VIN[1]. Previous model years experienced recalls for airbag sensors and brake components, issues potentially affecting later models.
Audi's proactive service campaigns sometimes address problems before formal recalls. Checking service history reveals whether these campaigns were completed. Dealers perform recall work free regardless of warranty status, making this less concerning for used buyers.
The 2024 A8's specifications reflect its philosophy of refined luxury over outright performance. All US models feature mild-hybrid technology for improved efficiency and smoother operation[2]. Understanding these specifications helps buyers evaluate whether the A8 meets their performance expectations.
The emphasis on comfort over sport distinguishes the A8 from BMW's more driver-focused 7 Series. This approach suits executives and passengers prioritizing serenity over engagement. Quattro all-wheel drive adds confidence without compromising the comfort-first mission.
The standard engine delivers 335 horsepower at 5,000-6,400 rpm and 369 lb-ft of torque from 1,370-4,500 rpm[11]. These figures trail competitors—the BMW 740i produces 375 hp while the Mercedes S450 generates 362 hp. However, real-world performance feels adequate for the class.
The broad torque curve ensures responsive acceleration in normal driving. Highway passing requires little planning, while the engine remains refined at all speeds. Fuel economy ratings of 19 city/28 highway/22 combined MPG prove respectable for the segment[2].
The turbocharged 3.0-liter V6 represents Audi's workhorse engine, proven across multiple models. Reliability generally proves good with proper maintenance, including regular oil changes using specified synthetic oil[11]. The turbocharger placement in the engine's "hot V" improves response but increases thermal stress.
The engine pairs with an eight-speed Tiptronic automatic transmission calibrated for smoothness over speed. Shifts occur imperceptibly in comfort mode, maintaining the serene driving experience A8 buyers expect. Sport mode sharpens responses but can't overcome the fundamental comfort orientation.
The 48-volt mild-hybrid system improves efficiency and refinement without full hybrid complexity. The system enables engine stop-start functionality that operates more smoothly than traditional systems[2]. During deceleration, the system recovers energy for storage in a lithium-ion battery.
This stored energy assists acceleration, reducing engine load and fuel consumption. The system also powers electrical accessories when the engine stops, maintaining climate control and electronics. While fuel savings remain modest, the refinement improvements justify the technology.
Official acceleration from 0-60 mph takes 5.6 seconds, competitive but not class-leading[11]. The BMW 740i achieves the same sprint in 5.3 seconds, while the Mercedes S450 requires 5.4 seconds. These differences prove negligible in real-world driving.
More important is the A8's composure during acceleration. The car gains speed serenely, without drama or noise. The suspension maintains its level attitude, while the cabin remains whisper-quiet. This refined acceleration suits the car's luxury mission better than outright speed would.
Every 2024 A8 includes quattro all-wheel drive as standard equipment, unlike BMW and Mercedes who charge extra for their systems[2]. The system provides confidence in adverse weather while enhancing stability during normal driving.
The rear-biased system sends 40% of torque forward under normal conditions, increasing to 70% when needed. This provides near-rear-wheel-drive dynamics during regular driving while ensuring traction when conditions deteriorate. The system operates transparently, never intruding on the driving experience.
EPA ratings of 19 mpg city, 28 mpg highway, and 22 mpg combined represent reasonable efficiency for a large luxury sedan[11]. Real-world economy depends heavily on driving style, with highway cruising potentially exceeding 30 mpg thanks to cylinder deactivation technology.
The 22.5-gallon fuel tank provides approximately 500 miles of highway range, reducing refueling stops on long journeys. Premium fuel is required, adding operational costs. Annual fuel expenses average $2,500-$3,000 for typical 12,000-mile driving.
Changes for 2024 remained minimal, reflecting the model's end-of-lifecycle status. Understanding these updates helps buyers determine whether 2024 models justify premiums over 2023 versions. According to Autvex analysis, the 2023 A8 offers nearly identical features at lower prices.
The limited updates disappoint those seeking the latest technology but benefit buyers preferring proven systems. The car's fundamental excellence remains unchanged, making model year less critical than condition and maintenance history.
The headline addition for 2024 was app-based remote start functionality through Audi Connect PLUS[2]. This feature allows owners to start their vehicles remotely using smartphones, pre-conditioning the cabin before entry. The system works from unlimited range with cellular connectivity.
Additional app integrations improved smartphone connectivity and infotainment functionality. These updates addressed previous criticisms about the aging MMI system, though they can't fully modernize the dated interface. The apps prove useful but don't transform the ownership experience.
Comparing 2024 to 2025 models reveals minimal changes. The 2025 received new wheel designs and interior trim options but no mechanical updates[7]. This similarity means 2024 models offer essentially the same experience at lower prices.
The 2025's status as the final gas-powered generation might create future collectibility, though this remains speculative. For practical purposes, 2024 models provide better value without sacrificing capability. Either year represents the culmination of the D5 generation's development.
The S8 transforms the A8's luxury platform into a genuine performance sedan. With 563 horsepower from its twin-turbo V8, the S8 competes with AMG and M Performance models while maintaining Audi's understated aesthetic[12]. Used S8 values prove particularly attractive for buyers seeking sleeper performance.
According to Autvex performance testing, the S8 delivers supercar acceleration with limousine comfort. This duality defines its appeal—executives can arrive at meetings composed and refreshed after exploiting the car's incredible performance capabilities.
Professional reviews praise the S8's completeness as a luxury performance sedan. Car and Driver notes its ability to "shrink around the driver" despite its size, crediting the rear-wheel steering and sport differential[12]. The car feels significantly smaller and more agile than its dimensions suggest.
The understated styling suits buyers avoiding attention. Only subtle badges, unique wheels, and quad exhaust tips distinguish it from standard A8s. This discretion proves valuable for those preferring performance without ostentation. Among Audi sport sedans, the S8 offers the best blend of performance and luxury.
The twin-turbocharged 4.0-liter V8 produces 563 horsepower and 590 lb-ft of torque, channeled through the same eight-speed automatic and quattro system[12]. This output matches or exceeds most competitors while maintaining reasonable fuel economy through cylinder deactivation.
The engine delivers power progressively rather than explosively. Torque peaks from 2,000-4,500 rpm, ensuring instant response regardless of speed. The exhaust note remains cultured—present but not intrusive. This refined delivery suits the car's executive express character.
Acceleration from 0-60 mph takes just 3.2-3.5 seconds depending on conditions, placing the S8 among the quickest sedans available[12]. Quarter-mile times of 11.5 seconds at 120+ mph confirm genuine performance capability. Yet the S8 never feels frantic or uncontrolled.
Launch control optimizes acceleration from standstill, managing torque delivery to minimize wheelspin. The all-wheel-drive system ensures consistent performance regardless of weather. More impressive is the 50-70 mph passing acceleration, where the S8's torque makes highway maneuvers effortless.
The S8's predictive adaptive suspension represents its most impressive technology. Cameras read the road ahead, adjusting suspension settings proactively rather than reactively[12]. This system particularly impresses when encountering bumps or potholes, which the car traverses with minimal disturbance.
The system offers multiple modes from comfort to dynamic, transforming the car's character. Comfort mode provides limousine-like isolation, while dynamic mode firms responses for enthusiastic driving. The breadth of capability exceeds most rivals, justifying the S8's premium pricing.
Used S8 values range from $75,000 to $95,000 depending on mileage and specification[13]. This represents exceptional value considering the $125,000+ original price. The dramatic depreciation benefits performance-oriented buyers seeking flagship capability at mid-level pricing.
Reliability concerns mirror standard A8s but with added complexity from performance components. Brake wear accelerates with enthusiastic driving, while the sophisticated suspension proves expensive to repair. Budget accordingly—annual maintenance could approach $2,000 even without major repairs.
The 2024 A8 faces formidable competition from established rivals and newcomers. Understanding these alternatives helps buyers determine whether the A8's specific attributes justify its selection. According to comparative testing, each competitor offers distinct advantages appealing to different priorities.
The German trio dominates this segment, though Genesis provides compelling value-oriented alternatives. Cross-shopping remains extensive, with buyers frequently testing all options before deciding[14].
The Mercedes-Benz S-Class sets luxury benchmarks with its opulent interior and advanced technology. Starting prices exceed the A8 by approximately $20,000, though the Mercedes justifies this through superior refinement and innovation[14]. The S-Class's MBUX system and ambient lighting create unmatched ambiance.
However, the A8 counters with:
