Overview
What do you get when you combine supercar performance with executive luxury and everyday practicality? The audi s8 answers that question emphatically, delivering a compelling blend that few rivals can match. This flagship saloon proves you don’t need to compromise between blistering acceleration and boardroom credibility.
Under the bonnet lies a 4.0-litre twin-turbo V8 producing 563bhp, catapulting this substantial four-door from standstill to 62mph in just 3.8 seconds. Yet the S8’s real achievement lies in how it delivers this performance with such refinement. The clever quattro all-wheel-drive system provides exceptional grip, while the advanced suspension keeps things composed whether you’re attacking country roads or cruising motorways.
Inside, the cabin showcases Audi’s finest materials and technology. The front seats offer 22-way adjustment with massage functions, while rear passengers enjoy limousine-levels of space and comfort. Despite its performance credentials, practicality hasn’t been forgotten – the 505-litre boot handles family duties with ease.
Running costs reflect the S8’s position at the premium end of the market, with fuel economy around 24mpg and high insurance premiums. However, for those seeking the ultimate executive express that can embarrass sports cars at traffic lights while whisking four adults across Europe in supreme comfort, the S8 makes a compelling case.
What's the Audi S8 Like to Drive?
The S8’s 4.0 litre twin turbo V8 engine is the star of the show, delivering devastating performance with refined delivery. Peak power of 563bhp arrives at 5,500rpm, while maximum torque of 590lb ft is available from just 2,050rpm.
Acceleration figures are genuinely supercar quick. The sprint to 62mph takes just 3.8 seconds, while the top speed is electronically limited to 155mph. With the optional dynamic package, this increases to 190mph.
The eight speed tiptronic automatic gearbox shifts smoothly in comfort mode and with lightning speed in dynamic settings. Paddle shifters provide manual control when desired, though the transmission is clever enough to handle most situations automatically.
Quattro all wheel drive is standard, providing exceptional traction and stability. The system can send up to 85% of power to the rear wheels when conditions allow, helping to deliver engaging rear wheel drive characteristics.
This executive saloon delivers performance that rivals dedicated sports cars while maintaining the refinement expected from a luxury four door.

CO2 emissions of 268g/km place the S8 in the highest road tax bracket. Company car users will face substantial benefit in kind charges due to the high P11D value and emissions rating.

Depreciation is steep initially but levels off after the first few years. Audi’s strong brand reputation helps maintain residual values better than some premium alternatives.
