Audi’s range of TDI diesel powerplants is about to receive an almighty performance boost, if reports out of the US are to be believed.

But rather than wind up the wick on any existing four-cylinder units, the German carmaker is reportedly looking to new ways of improving performance and efficiency.

The first is the ‘no substitute for cubic capacity’ method - in this case, Audi’s 283kW/850Nm 4.2 litre twin-turbo V8 diesel.

This engine is offered in the A8 luxury sedan, and Car And Driver reports it will be replaced with a new eight-cylinder engine, set to be unveiled at the Vienna Engine Symposium in April.

The new powerplant will lift the V8 TDI’s power figure to well over 300kW, but torque may remain stable or even fall to around 700Nm.

Again, it will be A8 customers who are offered the V8 diesel and the new engine could appear in the next-generation A8; set to be unveiled next year.

The extra kilowatts will reportedly trim the A8’s 0-100km/h time from 4.7 seconds to just over four seconds. Other Volkswagen Group models including the Porsche Panamera, Audi Q7, Bentley Continental and Volkswagen Touareg may also be powered by the same engine in future years.

Audi has poured much time and effort into electronic turbocharging over the last five years, but a second new diesel may receive electronic charging of a different kind.

A V6 TDI is also in the works, with performance to be boosted by a conventional turbocharger matched with an electronic supercharger.

The V6 will focus on a more ‘sporting’ drive than the new V8, and will be offered in various Audi ‘S’ models.
