The Audi S8 has been officially revealed. Details have been released for the performance model, confirming that the range-topping limousine uses V8 power once again. The combination of power and technology is likely to place the S8 close to the top of the pile when it comes to sports-focused limousines!

The engine fitted to the S8 should be familiar by now. It featured in the Porsche Panamera Turbo two years ago and can also be found under the bonnet of the Bentley Continental GT. A 4.0-litre TFSI unit, it uses Audi’s favoured bi-turbo setup with the turbochargers mounted inside the V, supplemented by a belt-alternator started and a lithium-ion battery. The setup allows Audi to counter turbo-lag whilst also offering strong fuel efficiency through the use of coasting and cylinder on demand.

In the S8, the power unit is rated to 571 hp and 800 Nm of torque. This is enough for a 250 km/h top speed with performance figures yet to be announced. The S8 gets iron-lined cylinder barrels and actuated flaps in the exhaust system which should mean that the sound will match to sledgehammer performance.

As with other Audi models, the A8 also runs a sophisticated suspension setup. Predictive active suspension, which features as an option on the standard A8, is now delivered as standard equipment, in combination with the adaptive air suspension. The former uses cameras to determine the road surface. The Audi drive select system differs slightly from other Audi models with five profiles, including a new “Comfort+” mode. As you would expect, the suspension parameters in this mode contribute to the smoothest possible ride with the body actively leaning into curves by as much as 3 degrees to reduce lateral forces.

All-wheel steering features on the Audi S8. A sport differential is fitted to the rear wheels which pushes power to the outside wheel under heavy cornering. Both systems are fitted as standard. The ceramic brake discs are an optional extra, measuring 420 mm at the front axle and 370 mm at the rear.

Visually, the S8 gains a set of 21-inch wheels. The front bumper is enhanced, together with the side sills. Audi’s characteristic silver mirror housings and quad tailpipes are also included as part of the package. Nine exterior colours arena option with carbon trim available inside. HD matrix LED headlights with Audi laser light and OLED rear lights are optional extras. New seats are fitted with ventilation and massage functions.

The Audi S8 will be made available in China, the US, Canada and South Korea, exclusively as a long wheelbase model. Pricing has not yet been announced.
