Audi Moves to Superchargers for New V-6

May 19, 2008

AUBURN HILLS, MI– Audi S4 will feature a V-6 engine. The new engine will serve as the successorto the 3.2L FSI with Valvetronic. And though the current engine is still aleader in refinement and is quite brisk, its 265 horsepower rating is downcompared to its newer rivals, particularly the 3.0L BMW twin-turbo straight sixand Mercedes-Benz’s recently updated 3.5L V-6, which now produces more than 300horsepower, according to www.automobile.com.

 

Theengine, dubbed 3.0 TFSI, uses a new Eaton supercharger. The V-6 enginegenerates 286 horsepower at 4,850 rpm and 310 lb-ft of torque at 2,500 rpm. Thesupercharger is supplemented by an air-to-air intercooler. These figures willmost likely apply to the engine that will be featured on the A6, rather thanthe S4, the report said.

Theprimary reason for Audi’s switch to superchargers is based on low-end torque,particularly at very low revs; in addition, the supercharged setup is lesscomplex and less costly to fit than a twin-turbo setup.
