Rather than running on the same underpinnings as cars like the Audi A8, VW’s upper echelon brands will benefit from a modified version that will allow the engine to sit within the car’s wheelbase according to Edmunds. The A8 also rides on MSB, but its engine sits much farther forward, which isn’t adequate for Porsche and Bentley’s performance expectations.
The architecture will be built with a combination of high-strength steel and aluminum in an effort to save weight while living up to increasingly demanding crash regulations. Porsche is expected to cut weight from the current Panamera, although a drastic reduction is unlikely.
Porsche will also continue to offer the wide selection of powertrain options including the V6, V8, hybrid and diesel options. The hybrid is also expected to lose weight thanks to increasing energy density in lithium ion battery packs. A 15 percent increase is predicted, which would translate to roughly 90 lbs being dropped from the hybrid system.
