Eaton Tapped The Superchargers For Audi
Posted Saturday, Jul 19, 2008 by autolive
Audi is using American supercharging muscle to give its new 3.0 liter TFSI V6 the desired wallop. Eaton Corporation has been enlisted by Ingolstadt to supply positive-displacement, Roots-type blowers that will work with direct injection to deliver 290 horsepower and fat, responsive torque down low on the tach. Roots blowers aren't anything new, but Eaton has refined the design with its latest Twin Vortices Series units. The TVS units add a fourth lobe to the rotors, and crank up the twist to 160 degrees for maximizing the amount of atmosphere the blower can pump out. Jettisonning turbochargers may help packaging when the V6 is crammed into the S4's engine bay, as well as reducing complexity by simplifying intake plumbing. 310 lb/ft of torque at 2,500 rpm will put a grin on anyone's face, and we'd expect to see this engine proliferate into many Audi engine bays.

Yeah, I'm not putting down the 2.0T, it's a good performance motor. But the real reason it looks so good here is because VW is badly mismanaging the engine choices in the base model.

Give us the polo or the UP! with a small TDI, and you've got yourselves a real winner.

Totally agree. I love the Rabbit, but the mileage is dismal for its class. I don't need a 2.5 in that thing. Give us a more efficient choice and I'll consider a Volkswagen.

Doesn't the GTI get slightly better mileage?

It literally pains me that this car wasn't rolled out three years ago. A big, beautiful coupe like this would have stirred 2005's "retro-muscle" scene into a frenzy.

It was poor ergonomics back in the 60s and 70s, and it's still poor ergonomics today.

Franz, I'm sure the essential info is replicated in the instrument cluster as warning indicators, where you can see it.
