The 2021 Audi Q8 blends coupe styling with SUV capability, delivering 335 horsepower through a turbocharged V-6 paired with 48-volt mild-hybrid technology[1]. Used prices now range from $31,500 to $46,500 depending on trim and mileage[2], representing substantial savings over the original $68,200+ MSRP. Electrical concerns and infotainment quirks warrant attention, but the Q8's handling dynamics and interior quality continue to satisfy owners five years into production.
Audi positioned the Q8 as a sportier, more personal alternative to the three-row Q7. Both share the same platform and 117.9-inch wheelbase, but the Q8 trades that third row for a dramatically sloping roofline and more aggressive proportions[3]. The result appeals to buyers who want SUV capability without the minivan-adjacent silhouette.
During a week-long test, the Q8 proved more athletic than its 5,004-pound curb weight suggested. Edmunds notes that it handles admirably through both tight and sweeping corners, with body roll nicely controlled and the suspension properly buttoned-down in Sport mode[1]. Only in higher-speed maneuvers does the weight become a limiting factor—a predictable characteristic for vehicles in this segment.
The dual-touchscreen MMI interface replaced Audi's previous rotary controller, and reactions remain mixed. The system looks impressive and provides crisp graphics, but Edmunds flagged it as potentially distracting to use[1]. Haptic feedback helps, though glancing away from the road to hit precise touch targets takes adjustment. For those new to Audi's ecosystem, understanding what Quattro all-wheel drive means provides useful context on the drivetrain.
| Specification | Value |
|---|---|
| Engine | 3.0L Turbocharged V-6 |
| Power | 335 hp @ 5,000 rpm |
| Torque | 369 lb-ft @ 1,370 rpm |
| Transmission | 8-speed shiftable automatic |
| Drivetrain | Quattro AWD |
| 0-60 mph | 5.6 seconds |
| Hybrid System | 48-volt mild hybrid |
The turbocharged six delivers confident acceleration, with peak torque arriving at just 1,370 rpm[2]. That low-rpm grunt matters for real-world driving—highway merging and passing require minimal planning. One point worth noting: Edmunds observed that throttle response feels slow in the default driving mode, so buyers who want immediate acceleration should select Dynamic mode[1].
| Measurement | Value |
|---|---|
| Length | 196.6 in |
| Width (with mirrors) | 86.2 in |
| Height | 67.2 in |
| Wheelbase | 117.9 in |
| Cargo Volume | 30.5 cu ft |
| Maximum Cargo | 60.7 cu ft |
| Curb Weight | 5,004 lbs |
| Ground Clearance | 5.8 in |
| Turning Circle | 43.5 ft |
| Towing Capacity | 7,700 lbs |
Cargo capacity measures 30.5 cubic feet behind the rear seats, expanding to 60.7 cubic feet with those seats folded[2]. The 7,700-pound towing capacity—available with the optional Towing Package—matches many body-on-frame SUVs[4].

| Rating | Value |
|---|---|
| EPA City | 18 mpg |
| EPA Highway | 23 mpg |
| EPA Combined | 20 mpg |
| Fuel Tank | 22.5 gallons |
| Monthly Fuel Cost | ~$245 |
| Required Fuel | Premium unleaded |
The 2021 model achieved 20 mpg combined—a slight improvement over the 2020's 18 mpg figure[2]. Real-world numbers depend heavily on driving style, and premium fuel is required. On the flip side, the mild-hybrid system makes stop-start operation nearly imperceptible, eliminating the jarring restarts common in traditional luxury SUVs. For those questioning fuel requirements, our guide explains whether Audis can run on regular gas.
The base Premium comes generously equipped with 20-inch wheels, LED headlights, adaptive air suspension, and a panoramic sunroof[4]. Inside, buyers receive the Virtual Cockpit digital instrument cluster, dual touchscreens, heated and ventilated front seats with leather upholstery, and three-zone automatic climate control. Standard safety tech includes Audi Pre Sense Front automatic emergency braking and blind-spot monitoring[2].
This mid-tier trim adds the Bang & Olufsen 3D sound system with 17 speakers and 730 watts, a 360-degree camera system, wireless phone charging, and a foot-activated power liftgate[2]. The HD Matrix LED headlight package becomes optionally available—an important upgrade given the base headlights' poor IIHS rating. Most used buyers gravitate toward Premium Plus as the best balance of features and value.
Top-tier Prestige models include head-up display, adaptive cruise control with Traffic Jam Assist, active lane-keeping, heated rear seats, and four-zone climate control[2]. HD Matrix LED headlights come standard. The optional Executive Package adds front seat massage and rear sunshades for those wanting maximum comfort.

The 2021 Q8 earned top marks across IIHS crashworthiness evaluations. All six crash test categories received "Good" ratings, including the demanding small overlap front tests for both driver and passenger sides[3]. The roof strength test recorded a 5.00 strength-to-weight ratio—well above the 4.00 threshold for a Good rating.
| Test | Rating |
|---|---|
| Small Overlap Front (Driver) | Good |
| Small Overlap Front (Passenger) | Good |
| Moderate Overlap Front | Good |
| Side Impact (Original) | Good |
| Side Impact (Updated) | Good |
| Roof Strength | Good (5.00 ratio) |
| Head Restraints & Seats | Good |
| Test | Rating |
|---|---|
| Vehicle-to-Vehicle | Superior |
| Pedestrian Detection (Day) | Superior |
The Audi Pre Sense Front system earned "Superior" ratings in both crash prevention categories[3]. In vehicle-to-vehicle testing at 25 mph, the system avoided collisions entirely. Pedestrian testing showed similar results—the Q8 avoided impacts with crossing adults and children at 25 mph while successfully detecting parallel-walking adults at speeds up to 37 mph[3].
Where the Q8 stumbles is headlight performance on lower trims. The standard LED reflector headlights on Premium and base Premium Plus trims received a "Poor" rating due to excessive glare—measuring 309% over threshold on sharp right curves[3]. The HD Matrix LED package, optional on Premium Plus and standard on Prestige, earned an "Acceptable" rating with no glare issues. When shopping used, verifying which headlight configuration a vehicle has matters significantly.
| Trim | Price Range | KBB Fair Market |
|---|---|---|
| Premium | $31,500–$36,000 | $36,240 |
| Premium Plus | $35,998–$44,000 | $36,629 |
| Prestige | $41,999–$46,500 | $41,680 |
Used 2021 Q8 prices have depreciated meaningfully from original MSRPs. Kelley Blue Book lists fair market values between $36,240 and $41,680 depending on trim[4], while Edmunds shows actual listings ranging from $31,500 to $46,500[2]. That spread reflects variation in mileage, condition, and equipment levels across the used market. For guidance on evaluating mileage, see how many miles are acceptable for a used car.
Owner experiences with the 2021 Q8 vary considerably. NHTSA complaints highlight electrical system problems, engine issues, and fuel system concerns as the most common categories[5]. A recall under NHTSA Campaign Number 22V516000 addressed fuel system issues, though some owners reported extended wait times for parts availability[5].
Reddit discussions reveal mixed sentiments. One owner documented persistent issues including center armrest replacement, HVAC problems, rattling sunroof, seat back popping, drivetrain malfunction errors, and frequent MMI system crashes[6]. After extended dealer attention, the situation reportedly improved. Another owner described their 2021 Q8 as "too good to be true," questioning whether problems would eventually emerge[7].
The 4-year/50,000-mile basic warranty may still cover lower-mileage 2021 examples[2]. For vehicles approaching warranty limits, extended coverage merits consideration. If you encounter drive system malfunctions, our guide covers diagnostic steps. For service alternatives, see whether Audis can be serviced at independent shops.
The Q8 represents Audi's vision of a flagship SUV prioritizing style and dynamics over maximum passenger capacity.
Strengths:
Weaknesses:
The 2021 Q8 appeals to buyers who want their luxury SUV to feel special rather than purely utilitarian. The coupe-like roofline and athletic handling create a more engaging ownership experience than traditional three-row competitors provide, while the turbocharged V-6 delivers genuinely quick acceleration.
