Inside Porsche's new V8 and V6 powertrains

Porsche broke a “golden rule” of automotive engineering when it began development of the second generation Panamera: Never develop a new car, a new powertrain and a new factory simultaneously. So confessed Dr. Manfred Harrer, Vice President of Chassis Development.

But despite the transgression, the resulting technologies lift the latest Panamera into a new dimension of sedan capabilities, as previously reported (http://articles.sae.org/14896/). We now have full details of its powertrain, plus experience of how the most powerful, twin-scroll gasoline V8 performs on track.
