The Audi S8 Quattro is the range topping model in the '8' series.
The new 5.2-litre V10 petrol engine has performance-biased pedigree
that perfectly suits the ultimate A8. Maximum power of 450 bhp
is delivered at 7,000 rpm, and peak torque of 400 lb-ft at 3,500
rpm, with up to 90 per cent of this total available from just
2,300 rpm, giving the S8 Quattro a 0-60 mph time of 5.1 seconds
and a top speed limited electronically to 155 mph.
The S8 uses the Lamborghini Gallardo's 5.0-litre
unit, developed by Lamborghini in conjunction with Audi, as
its foundation, the 5.2-litre V10 incorporates bespoke features
that tailor its much-loved character to meet luxury saloon requirements,
without diluting it. These include Audi FSI direct petrol injection
for optimum responsiveness and efficiency, and the addition
of a balancing shaft for maximum engine refinement.
The first ever V10 from Audi is effectively harnessed by a chassis
combining adaptive air suspension with the latest generation
quattro permanent four-wheel-drive system, featuring a standard
torque split of 40:60 (front / rear) that helps to optimize
axle load distribution for even greater agility and steering
The air suspension of the Audi S8 is based on the Sport set-up
offered throughout the A8 range, featuring firmer damping and
a 1 inch ride height reduction in each of its four modes. The
system has been modified for the Audi S8 quattro to suit its
even more pronounced sporting bias, with revisions to the suspension
mounts and to the shock absorbers within the air-spring bellows
designed to maximize roll resistance. The speed dependent Servotronic
power steering has also been further sharpened through revisions
to the steering ratio giving a reduction in lock-to-lock turns.
