Chrysler will add fuel-efficient diesel-powered and hybrid models to its line-up in the next couple of years. The company wants to eliminate models that overlap each other and add new vehicles that will push the sales up.

One of the biggest problems for Chrysler is the PT Cruiser. It is considered to be an outdated model that hasn't changed its look since the first debut.

The company also has problems with the Pacifica and the Dodge Magnum. But not even the Sebring does not have a better life: last month, Toyota's Camry outsold the Sebring by more than six-to-one. So, the company has decided that the Sebring will be either replaced or will get a radical overhaul

Chrysler, working with General Motors Corp. and BMW A.G., will begin selling gas-electric hybrids SUVs next year. The Chrysler Aspen and Dodge Durango hybrids show a 40 percent increase in fuel efficiency during city driving and a 20 percent increase on the highway, company officials said.

Diesels have also helped Chrysler showcase more efficient SUVs. Chrysler also began selling a Jeep Grand Cherokee with a 3-liter diesel engine this year that reaches 23 mpg on the highway. Executives have said the engine could make its way into more vehicles. However, strict government emission standards in some states limit the company's options, until a better cleaner diesel is available.

The company is also investing in its 2.4-liter four-cylinder world engine, which has helped vehicles such as the Dodge Avenger, Jeep Patriot and Compass achieve more than 30 mpg. Chrysler announced in August it would begin making the engines direct injection capable, which could further increase the engine's efficiency and power.
