Peugeot Combines Diesel & Electric

When it comes to the now-increasing argument about fuel-efficient powertrains, it is generally diesel versus hybrid, with each side coming down on why their favorite is a better solution.

Peugeot is taking the Miller Lite solution—“Less Filling”/”Tastes Great”—by combining the two in the Peugeot 508 RXH, which is a diesel-electric hybrid. Why not have both?

Following on the launch of the compact 3008 Hybrid4, which has the same powertrain setup, the recently launched (Spring 2011), up-market sedan and wagon Peugeot 508, which has a range of gasoline and diesel engines, will be offering a vehicle that has a European combined cycle of 70.6 mpg, thanks to the combination of the 2.0-liter diesel engine combined with the electric drive motor (the maximum power is 200 bhp). The vehicle can be driven (power permitting) as a full electric vehicle. There is also four-wheel drive capability.

Certainly diesel engines are more popular in the European market than they are in the U.S. market. Yet the combination of diesel and hybrid—undoubtedly at a non-trivial price premium—certainly provides significant fuel efficiency.

The Peugeot 508 RXH will be unveiled at the Frankfurt Motor Show in September and go on sale in early 2012.
