Chrysler, EPA Partnership Hint at Hybrid Minivan

Chrysler Town & Country

Chrysler and the Environmental Protection Agency announced today a joint venture to develop a hybrid system that could eventually come to the automaker’s large cars and trucks.

The powertrain is a hydraulic hybrid system, which is similar to those powering hybrid public buses and large commercial trucks today. The system pairs a traditional gasoline engine with a hydraulic pump, electric motor and a two-speed automatic transmission. The hydraulic pump pushes high-pressured fluid from an accumulator to an axle hydraulic motor, which then powers the wheels. Like a more traditional hybrid system, the pump takes pressure off the gasoline powertrain during initial acceleration and deceleration, which in turn increases gas mileage.

While the system will still take some time to scale down — the system currently requires a 14.4-gallon high-pressure accumulator on top of traditional gas tank — it does suggest that Chrysler is taking a new interest toward hybrid technology.

The automaker currently has no hybrid systems, but CEO Sergio Marchionne has said a hybrid model could show up soon. During a Q&A session at the launch of the new 2011 Chrysler Town & Country and Dodge Grand Caravan yesterday, Marchionne said a hybrid minivan and the Chrysler 300 hybrid would arrive at dealerships by 2013, according to, a Chrysler enthusiast website as well as other outlets in attendance. That would coincide well with Marchionne’s desire to better differentiate the automaker’s two minivans and make them “more versatile.”

The hydraulic hybrid system is slated to go into a 2011 Chrysler Town & Country, which is mated to a 2.4-liter four-cylinder for testing purposes.

Veyr least an alternative from Toyota's...

Scale of engineering is important here - cost, reliability, mpg rating etc. Bus/truck operation is also very different from minivan too...

Nice idea! I hope it catches on.


If I remember correctly there was an aspen hybrid?

Yep that hybrid was through a partnership between Daimler and BMW. It did not sell well and that partnership is obviously not alive with the new Chrysler.

Not bad, I would like to hear more on the minivan story though, will they keep both the grand caravan and the town and country?

Nice one.That's an interesting idea!
