peugeot-3008-hybrid4.jpgAt the 2010 Paris Auto Show in October, Peugeot is expected to debut the Peugeot 3008 Hybrid4, its long-anticipated diesel hybrid. As noted in a 2009 preview on this site, the crossover vehicle will be available in 2011 and is expected to deliver incredible fuel efficiency. In fact, most auto review sites are citing the company’s claim that the 3008 Hybrid4 will get the equivalent of about 62 mpg.

The impressive fuel economy is due to the fact that diesel engines are more fuel efficient than their gas counterparts, using about 30 percent less fuel in some cases. So when a diesel engine is paired with an electric motor, the fuel economy potential is enormous.

And while there have been many diesel-hybrids announced and prototyped by other auto makers including Audi, BMW, Hyundai, Mercedes, and Volvo, very little action has resulted.

With such potential for great fuel economy, the one question that comes to mind is why have there been so few diesel hybrids before this? As CNet points out, “many have been skeptical of a diesel hybrid, since a diesel engine’s high torque does not lend itself easily to incorporation with an electric motor.”

Peugeot gets around this by essentially keeping the diesel and hybrid elements separate. The diesel engine powers the front wheels; the electric motor powers the rear wheels. The two can work one at a time or at the same time. However, they are not connected mechanically.

Specifically, the Peugeot 3008 Hybrid4 will use Peugeot’s 2.0 liter HDi FAP diesel engine and an electric motor. The diesel engine is rated at 163 hp and the motor is 37 hp.

An automatic mode relies on the 3008 Hybrid4’s computer to determine the best use of the diesel engine and the electric motor. A four wheel drive mode used both for maximum traction. A sport mode uses both in a way that delivers maximum acceleration. And a zero-emissions vehicle (ZEV) mode relies on the electric motor, bringing in the diesel only if more power is needed for accelerating into traffic.

The 3008 Hybrid4 will come with some high-end features including a sunroof, heads-up display, Bluetooth connectivity, and a navigation system, according to a Car and Driver preview. It will also incorporate other 3008 crossover vehicle technology (available in the non-hybrid version) such as dynamic roll control.

The 3008 Hybrid4 will be produced in France. It will be available in Europe, but not the U.S. The price of the Peugeot 3008 Hybrid4 is expected to be in the $40,000 range.
