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.
A Jalopnik reader purportedly got hold of a Harris Opinion Survey about the upcoming CTS wagon, and assuming it's on the level, it brings forth a treasure trove of information. For example, as you can see above, it seems we now have a first look at official imagery of the CTS in 2-box guise. We like what we see...perhaps even more than we like the CTS Coupe. We especially dig the way those super-tall taillamps look from behind. We'll reserve final judgement for whenever Cadillac officially unveils the car, but things appear to be proceeding very nicely.
Underhood, the doc tells us that it's going to be direct-injected engines only. A 3.0L V6 producing 260 horses replaces the current, non-DI 3.6 as the base mill, with the now-familiar 304-horse 3.6L again assuming the top spot. Both will be connected to 6-speed automatics, and highway mileage is said to be 27 mpg. 25 cubic feet of your stuff will fit behind the second row, and if you flip those back seats down, cargo capacity increases to 58 cubes. A power liftgate ensures you won't strain yourself opening the rear hatch. According to the leaked materials, pricing will range from $37,500 to $42,500.
Will Americans embrace a new luxury wagon? We're gonna find out soon enough.
