Details: Audi's new supercharged 3.0-liter V6
Automakers in the U.S. are just starting to truly embrace turbocharging, but Audi is going against that grain by choosing to supercharge its new 3.0L V6. We already told you some details about the new powerplant, and now we're hearing new specs from Autocar. The British website is reporting that the 3.0L V6 due to power the next S4 will be force-fed by an Eaton Supercharger to produce a power-output of 286 horsepower at 4,800 rpm and 310 lb-ft at 2,500 rpm. We'd heard earlier that the output of the supercharged 3.0L would be closer to 350 hp in the S4 and detuned to 290 hp for the mid-range A6, so this new report from Autocar has us a bit confused. We're assuming that the British outlet is just referring to the less powerful version of the engine that will power the A6 and doesn't yet know exact power figures for the S4 version. At least we're hoping so, since a less powerful S4 is no fun for anyone
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.
