More official information on the 286bhp V6 engine to join the Audi range
9 May 2008

Audi has revealed more details about its forthcoming supercharged V6 engine, which will power the next S4 and feature in next year’s A6 refresh.The 3.0-litre, direct-injection unit produces 286bhp at 4850rpm, and 310lb ft torque at 2500rpm. It’ll be known as the 3.0-litre TFSI, even though the ‘T’ traditionally stands for ‘turbo’. The new engine uses an Eaton supercharger and has an air-to-air intercooler rather than a water-to-air unit. Speculation was rife that Audi would fit its 3.2-litre V6 with twin turbos in an effort to rival BMW’s similarly specified 3.0-litre unit, which has just won Engine of the Year for the second year in succession. But the Ingolstadt engineers decided that the increasing weight of cars demanded a solution promising greater torque at low revs. Audi bosses believe that larger models like the Q7 and A8 - also likely to get the supercharged V6 - will benefit from low-down power delivery. Packaging a supercharger is also simpler than a twin-turbo, because it sits between the cylinders, although this does raise the centre of gravity.

With the current focus on emissions and economy, it seems strange that Audi have chosen a supercharged engine, even more so a positive-displacement supercharger.

That said, if the boost level is low, the efficiency of the supercharger is much better and the undramatic headline power figure suggests this may be the case.

Due to the increasing weight of cars Audi's engineers decided to use a supercharger to boost low rev torque.Here's an idea, how about they try building lighter cars? I'm pretty much sure that would be better for economy, emissions etc...

How is boost limited on a mechanically supercharged engine? On a turbo it's easy to up the boost as it's controlled by the wastegate, you might have to change the 'charger pulley to up the boost on this.
