The most powerful diesel luxury car gains added horsepower and torque
Superchips, the world leader in engine management system tuning, has extracted even more power and torque out of Audi’s potent A8 4.0 litre V8 TDI, the world’s most powerful diesel-engined luxury car.
Reprogramming the engine control unit (ECU) has enabled Superchips to give the A8 V8 TDI the responsiveness of a thoroughbred sports car. Power output is boosted from an already impressive 277 bhp at 3,642 rpm to an amazing 316 bhp at 3,546 rpm – an increase of 42 bhp. Torque is increased by 103 Nm, with the Superchips conversion resulting in 729 Nm at 2,683 rpm, compared to the original maximum of 635 Nm at 2,619 rpm, taking the luxury saloon to a new level of performance.
Such a major increase in power and torque would usually be matched by an equally major price increase. However, this is not so with the Superchips conversion, which costs just £511.13, inclusive of VAT – less than one per cent of the A8 V8 TDI’s £57,820 retail price.
The conversion can be carried out at any one of Superchips’ 85 dealers nationwide, or at the company’s headquarters in Buckingham. In some parts of the country, it can also be done at the customer’s home or place of work, courtesy of one of the network’s mobile units. In each case the job only takes around 45 minutes to complete. If required, Superchips can even arrange favourable insurance via its specialist broker, Firebond.Published 10 September 2004
