The Chrysler group's powertrain offerings in the next three years will be among the most diverse in the industry.
Chrysler plans to offer diesels, continuously variable transmissions and rear-wheel-drive hybrid models. Most gasoline-powered engines will run on E85. Additionally, DaimlerChrysler will develop a new family of V-6 engines that will be shared by Chrysler and Mercedes-Benz.
Here's a look at Chrysler's powertrain plans:
- Diesels: The 2007 Jeep Grand Cherokee offers the Mercedes-Benz 3.0-liter common rail turbodiesel V-6, essentially the same engine as used in the E320 sedan. The U.S. version is rated at 215 hp and 376 pounds-feet of torque. The Grand Cherokee already is sold with a diesel engine in Europe.
A larger-displacement, Cummins-built diesel inline six offering more horsepower and torque than the 5.9-liter diesel inline six will be available in the 2007 Ram 2500 and 3500 pickups.
Two other diesel engines are in Dodge's future. Cummins will provide a 4.2-liter V-6 and a 5.6-liter V-8. Both engines are scheduled for 2010. Preliminary specifications show the Dodge diesels rated at 190-hp for the V-6 and the 260-hp for the V-8.
The V-6 is likely to be installed in the Durango and possibly the Dakota. The Ram 1500 is expected to get the V-8 diesel. That engine will compete with a new 4.4-liter V-8 diesel the Ford F-150 will offer toward the end of the decade.
- New V-6s: A decision to replace all of the company's V-6 engines with a new family of more efficient six-cylinder engines is expected by the end of the year, says Chrysler group CEO Tom LaSorda. The engines could debut as early as the 2010 model year.
The new engines would be engineered using a modular design, so a range of applications could be created for the Chrysler group and Mercedes-Benz.
- Hybrids: A rwd Dodge Durango will be available in 2008 with an optional gasoline-electric two-mode powertrain that could offer a 25 percent boost in fuel economy. It may be labeled a 2009 model. The Durango hybrid will be equipped with Chrysler's cylinder cutoff technology.
The hybrid's transmission is being developed as part of a joint project involving DaimlerChrysler, BMW and General Motors. The transmission will be assembled by GM.
Engineers are also working on a front-drive hybrid powertrain that could be ready for production around 2009.
- Transmissions: Chrysler is shifting to more fuel-efficient transmissions this year with the introduction of a six-speed automatic designed in-house. The transmission is expected to be available in the 2007 Chrysler Sebring.
A continuously variable transmission supplied by Jatco Ltd. is available in the 2007 Dodge Caliber and Jeep Compass and Patriot.
