VW Touareg Hybrid: Review of the prototype

VW Touareg Hybrid
Interesting review here of the VW Touareg Hybrid prototype.

While General Motors opted for a highly optimized version of its 6.0-liter V8 for its hybrid trucks, Volkswagen is instead using one of the newest engines in the group in the Touareg. The new 3.0-liter TSI V6 debuted in 2009 in the Audi A6 and S4. The new hybrid gets the engine in the more powerful 333 horsepower / 324 pound-foot form used in the sporting S4. VW gets this output from a comparatively small engine through a combination of direct fuel injection with a mechanical supercharger. Even before factoring in the hybrid system, the V6 already benefits from the advantages of engine downsizing. The six cylinder engine has output on a par with the larger 4.2-liter V8 also offered in Touareg, but in more efficient package. In addition to the smaller displacement, the engine also features other enhancements like a water pump that can be switched off during engine warm-up. This reduces the parasitic draw while speeding up the warm up.
