Audi S8

	Based on the aluminium A8 and powered by a mighty V10 engine which originally debuted in Lamborghini’s Gallardo, the 444bhp machine rivals the likes of the new Mercedes S63 AMG

It's the ultimate recipe for fun... Take one of the finest luxury saloons money can buy, add the beating heart of a thrilling supercar and stand well back. Although it sounds like a fantasy, the Audi S8 combines the above ingredients – and it has just arrived in the UK.

Based on the aluminium A8 and powered by a mighty V10 engine which originally debuted in Lamborghini’s Gallardo, the 444bhp machine rivals the likes of the new Mercedes S63 AMG.

On the road, the result is breathtaking. It’s as if the S8 wants to prove that it is every inch the super-saloon everyone knows it should be – even the gentlest dab of the throttle sends nearly two tonnes of luxury limo hurtling forwards. The drama is accompan­ied by a truly intoxicating soundtrack from under the bonnet.

Official figures claim 0-62mph takes 5.1 seconds, and the Audi feels every bit as fast in day-to-day driving conditions. The trouble is, the acceleration is so thrilling that the rest of the car feels like a bit of a letdown.

We can’t fault the imposing styling, unique alloys or beautifully crafted cabin, but the S8 is an enormous machine and it simply hasn’t got the agility to match its performance. With the air-suspension in dynamic mode, the ride is uncomfortably hard, while the steering lacks the feel of a true sports saloon.

At £70,825, the big-hitting Audi isn’t cheap, but it will still undercut flagship versions of Mercedes’ AMG-tuned S-Class. However, less potent A8 models offer a better overall package.
