ABOUT THE 2021 AUDI Q8
The 2021 Audi Q8 is a large, five-seat coupe-styled SUV, the third model year of the first-generation Q8. In the US it uses the 55 TFSI powertrain: a 3.0-litre turbocharged V6 rated at 335 hp and 369 lb-ft, with a 48-volt mild-hybrid system, an eight-speed Tiptronic automatic and quattro all-wheel drive. Audi quoted 0–60 mph in 5.6 seconds.
Where 2021 sits
The Q8 went on sale in the US for 2019 as Audi’s flagship SUV, sharing its platform with the Q7, Porsche Cayenne and Lamborghini Urus. For 2021 the Q8 family grew, with the V8-powered SQ8 and the high-performance RS Q8 joining the regular model. The standard car carried on with its single V6 powertrain. Like the Q7, it was built at the Volkswagen Group plant in Bratislava, Slovakia.
What it is like
The Q8 is shorter and lower than the Q7 and gives up its third row, trading space for a sleeker, frameless-door design. The cabin uses the same twin-touchscreen layout as the A8. Rear passengers still get good space, and the boot is large for a coupe-style SUV. Air suspension and all-wheel steering were available.
Buying one today
Check that all screens and driver-assistance features work, inspect air suspension if fitted, and look for a complete service record. Large wheels and tyres add to running costs.
Rivals
