Quick answer: A used 2024 Audi A8 presents a compelling value in 2026, trading between $50,000 and $70,000. This represents a steep 40% to 45% depreciation from its original $90,900 base MSRP. While it offers unmatched cabin quietness, standard quattro all-wheel drive, and traditional luxury, potential buyers must weigh this discount against an average 10-year maintenance cost of $10,618 and a 5/10 reliability rating.
Key takeaways:
The used car market for full-size luxury sedans is notorious for rapid depreciation, and the 2024 Audi A8 is no exception. For buyers looking at a two-year-old vehicle in 2026, this depreciation curve shifts from a financial penalty for the original owner into a major opportunity.
When new, the base 2024 Audi A8 L 55 TFSI quattro started at a base manufacturer suggested retail price (MSRP) of $90,900. When optioned with typical packages such as the Executive Package ($3,650), Comfort Plus Package ($4,100), or the Luxury Package ($5,400), final retail prices regularly exceeded $105,000.
By mid-2026, the retail market has adjusted these figures significantly. Based on current market transactions, a used 2024 Audi A8 L 55 TFSI in good condition with average mileage (20,000 to 24,000 miles) carries a retail price of approximately $57,990 to $62,300. Private party transactions range lower, averaging between $54,900 and $58,500. For trade-ins, dealers typically offer between $52,500 and $56,000, depending on vehicle condition.
Below is a breakdown of the observed used price ranges in 2026 based on vehicle condition:
| Condition | Used Price Range | Average Mileage |
|---|---|---|
| Rough / High Mileage | $50,000 - $53,000 | 30,000+ miles |
| Average / Fair | $53,000 - $57,000 | 20,000 - 30,000 miles |
| Clean / Good | $57,000 - $63,000 | 10,000 - 20,000 miles |
| Excellent / Certified Pre-Owned | $63,000 - $70,000 | Under 10,000 miles |
This price structure indicates that the 2024 model has lost roughly 40% to 45% of its initial value in just two years. For comparison, you can explore the pricing details of its predecessor in our 2023 Audi A8 Review to see how the depreciation trajectory establishes itself over a longer ownership timeline.
The steep depreciation of the A8 is concentrated in its first year of ownership. Third-party appraisal data from Edmunds indicates that the vehicle lost approximately $35,669 of its value in its first year. The second-year loss was much more moderate, dropping by an additional $7,971.
This stabilizing depreciation rate makes the second and third years of ownership the financial sweet spot. Used buyers avoid the massive initial hit while purchasing a sedan that still retains most of its factory warranty and wear-and-tear life.

Reliability is the single most important factor when purchasing a used luxury flagship out of warranty. While the A8 offers an exceptionally refined driving experience, it contains complex mechanical and electrical systems that require careful inspection.
Professional consumer rating groups paint a mixed picture of A8 dependability. J.D. Power predicts average reliability for the 2024 Audi A8, aligning it with mid-tier ratings in the luxury segment. However, independent enthusiast forums and consumer guides like The Car Guide rate the vehicle at a low 5/10 for reliability.
This discrepancy highlights a common trend: owners report high satisfaction with comfort and performance, but professionals flag the high frequency and cost of repairs. According to statistical data from CarEdge, the Audi A8 averages $10,618 in maintenance and repair costs over its first ten years of service. This is $828 more than the average vehicle but is competitive within the German luxury import market. The probability of the A8 requiring a major repair during these ten years is estimated at 27.7%.
Used buyers should budget for potential out-of-warranty repairs. Based on long-term data for the D5 generation, several specific areas require attention.
The A8 comes standard with an electronically controlled adaptive air suspension that provides excellent ride comfort. However, the rubber air bags and control valves are prone to wear.
Symptoms of failure include the car sagging on one side after parking, an unusually harsh ride, or dashboard warning lights. Replacing a single air strut assembly out of warranty typically costs between $2,000 and $2,500 at an authorized dealership, or slightly less at a specialized independent shop.
The 3.0L V6 uses a 48-volt mild-hybrid system featuring a belt alternator starter (BAS) and a small lithium-ion battery. This system allows the engine to coast silently and improves start-stop transitions.
However, early D5 models suffered from alternator-starter failures that could drain the battery and leave drivers stranded. While Audi issued service campaigns to address this, used buyers must verify that the latest software updates and components are present. Electrical gremlins affecting the dual touchscreen MMI infotainment system and driver assistance sensors also occur occasionally, requiring expensive diagnostic time.
Enthusiasts and technicians note that the turbocharged 3.0L V6 can consume oil between regular 10,000-mile service intervals. While some oil usage is normal for turbocharged German engines, excessive consumption can lead to carbon buildup on the valves or premature turbocharger wear. Regular oil level checks are mandatory. Additionally, the timing chain tensioners should be listened to closely during cold starts; any metallic rattling could indicate tensioner wear, which is a major engine repair.

The performance profile of the 2024 Audi A8 is engineered around effortless highway cruising rather than aggressive sports-car handling. It prioritizes cabin isolation and linear power delivery.
The base 55 TFSI trim features a 3.0-liter single-turbocharged V6 engine paired with a 48-volt mild-hybrid system. This powertrain produces 335 horsepower and 369 lb-ft of torque. The engine sends power through an eight-speed Tiptronic automatic transmission to Audi's standard quattro all-wheel-drive system.
On the road, the V6 is exceptionally smooth. Peak torque arrives at a low 1,370 rpm, allowing the vehicle to accelerate away from traffic lights with minimal throttle input. The transmission is calibrated to upshift early, keeping cabin noise to a whisper.
The 2024 Audi A8 L 55 TFSI accelerates from 0 to 60 mph in 5.6 seconds. This performance is competitive but lags slightly behind key rivals. For comparison, the standard BMW 740i produces 375 horsepower and hits 60 mph in 5.3 seconds, while the Mercedes-Benz S450 delivers 362 horsepower and reaches 60 mph in 5.4 seconds. In real-world highway merging and overtaking, these tenths of a second are unnoticeable. The A8 feels stable and capable at all legal speeds.
The EPA rates the 2024 Audi A8 L 55 TFSI at 19 mpg city, 28 mpg highway, and 22 mpg combined. The mild-hybrid system helps achieve these numbers by allowing the engine to shut off during coasting under light loads.
In real-world testing, highway economy can reach up to 30 mpg on long cruises, aided by the car's aerodynamic profile. The large 22.5-gallon fuel tank provides a highway cruising range of over 500 miles. Premium unleaded fuel is required, which adds to the operating costs.
For buyers who find the standard V6 lacking in power, the high-performance Audi S8 variant is an exceptionally attractive used purchase. It swaps the V6 for a twin-turbocharged V8 and adds advanced chassis technology.
The 2024 Audi S8 features a 4.0-liter twin-turbocharged V8 engine producing 563 horsepower and 590 lb-ft of torque. This V8 accelerates the large sedan from 0 to 60 mph in just 3.2 seconds, putting its performance on par with many dedicated sports cars.
The S8 uses a sport-tuned eight-speed automatic transmission and a torque-vectoring rear sport differential that helps push the car through corners, reducing the sensation of its substantial curb weight.
A key feature of the S8 is its Predictive Active Suspension. This system uses front-facing cameras to scan the road ahead for imperfections. It then uses electromechanical actuators to raise or lower each wheel individually, pre-conditioning the suspension for potholes or bumps.
The system also active-leans the body into corners to reduce lateral forces on passengers and raises the car by 2 inches when a door is opened to make entry and exit easier.
The original MSRP for the 2024 Audi S8 started at $123,400, with optioned models easily passing $135,000. Because high-performance luxury cars depreciate even faster than standard models, used S8 prices in 2026 have dropped significantly.
A clean 2024 S8 can now be purchased for approximately $94,200. This makes it an outstanding performance bargain, though buyers must remain aware that maintenance costs for the V8, large brakes, and complex active suspension will be higher than the standard V6. For a complete review of the sport variant's features, read Car and Driver's 2024 Audi S8 Review for track test results.
Before purchasing a used A8, it is important to evaluate how it compares to its primary segment rivals. Each vehicle in this class offers a distinct personality.
The Mercedes-Benz S-Class remains the traditional benchmark for full-size luxury. The 2024 S450 offers a more opulent cabin, a more prestigious badge, and more advanced driver assistance technology than the A8.
However, the S-Class carries a significant price premium, with used 2024 models typically retailing $15,000 to $20,000 higher than a comparable A8. The Mercedes infotainment interface is also highly touch-sensitive and can be distracting to use compared to Audi's straightforward layout.
The BMW 7 Series was redesigned for the 2023 model year, meaning the 2024 model features a much fresher exterior design and a highly futuristic cabin dominated by a curved display. It offers superior handling dynamics and a more powerful standard engine.
The drawback to the 7 Series is its highly controversial exterior styling, which does not appeal to all buyers. The Audi A8 remains the choice for those who prefer an understated, conservative design. For buyers considering a slightly newer model, compare these traits against the 2025 Audi A8 Review to see how the segment evolved.
The Genesis G90 is the value champion of the segment. It comes fully loaded with features that are optional on German cars, and its used price is highly competitive. The Genesis also features an industry-leading 10-year warranty that transfer to second owners under specific certified pre-owned terms.
The Audi A8 maintains an advantage in brand prestige, high-speed highway stability, and the refinement of its V6 powertrain.
The landscape for the Audi A8 has shifted dramatically as Audi executes its long-term product strategy. For buyers in 2026, understanding the vehicle's production status is critical for predicting future parts support and resale value.
Audi quietly closed the order books for the gas-powered A8 in Germany and the wider European Union on February 18, 2026. The vehicle was removed from the online configurator without a formal announcement or farewell edition.
Production at the Neckarsulm plant in Germany has ended. While Audi's joint-venture facility in China will continue to produce long-wheelbase variants for the local market through the end of 2026, new gas-powered A8 models are no longer being manufactured for Western markets. US and UK buyers looking for a brand-new model must rely entirely on remaining dealer inventory. This marks the end of the D5 generation's nine-year run.
During this transition, Audi CEO Gernot Döllner confirmed that the upcoming Q9 large SUV will serve as the brand's temporary flagship model, reflecting the market's shift toward high-margin utility vehicles. To see what the final year of production offered, consult our 2026 Audi A8 Review for the final specifications.
Audi originally intended to replace the gas A8 with a fully electric sedan based on the Grandsphere concept by 2027. However, the development program (originally known as the "Landjet" project) suffered delays due to software development setbacks and shifts in platform investment.
Audi now projects that the next-generation A8 successor will not arrive until the end of the decade, likely around 2029 or 2030. When it does return, the powertrain strategy remains fluid; while an electric vehicle is planned, Audi has not ruled out the integration of combustion-hybrid powertrains to meet shifting market demands.
Purchasing a used 2024 Audi A8 in 2026 represents an excellent way to experience flagship luxury at a mid-size price point. To minimize risk, used buyers should follow a structured purchase process:
Common issues include adaptive air suspension leaks costing up to $2,500 per wheel, alternator-starter failures in the 48-volt mild-hybrid system, moderate oil consumption in the 3.0L V6, and occasional electrical glitches in the dual MMI touchscreen system.
The A8 ranks average for reliability in professional studies, but long-term guides rate it a 5/10 due to the high cost of components. It is a reliable used car if purchased with a complete service history and remaining warranty, but can be expensive to repair out of warranty.
According to data from CarEdge, the Audi A8 costs approximately $10,618 in maintenance and repairs over its first ten years. This is slightly above the industry average but normal for a large German luxury import.
Yes. Audi officially closed new orders for the gas-powered A8 D5 in Germany on February 18, 2026. European production has halted, and US sales are currently limited to remaining dealer inventory. A successor is planned for the end of the decade.
The 2024 Audi S8 produces 563 horsepower and 590 lb-ft of torque from its 4.0-liter twin-turbo V8, achieving a 0-60 mph time of 3.2 seconds.
