Chrysler unveils hybrid gas/electric Sebring sedan

Auburn Hills, Michigan – On Tuesday, the Chrysler Group unveiled a Chrysler Sebring sedan with its patented Through-the-Road (TTR) hybrid powertrain. The Sebring is the third developmental vehicle equipped with TTR technology, joining the Dodge Durango HEV sport-utility vehicle unveiled in 1999 and the Jeep Liberty HEV sport-utility vehicle first shown at the Washington, D.C., auto show in December 2001.

The Sebring HEV is equipped with a 2.4-litre inline four cylinder gasoline engine that drives the front wheels. An electric motor and battery pack provide additional power to the rear wheels when needed for acceleration or hill climbing. Thus, a smaller internal combustion gas engine can be used, resulting in increased fuel efficiency and better performance. For example, the Sebring HEV has a 0-60 mph time of 9.1 seconds, compared with 11.7 seconds for a comparable gas-powered vehicle. The TTR powertrain also provides four-wheel drive capability.

The system is called TTR (Through-the-Road) because there is no physical connection between the front and rear axles or the engine and motor. The two are controlled and coordinated by computer, responding to changes in the vehicle’s traction coupled through the road.

In each of these vehicles, the TTR hybrid powertrain can achieve a 20-30 percent improvement in fuel efficiency and lower emissions, while providing performance that matches or beats that of a comparable conventional vehicle. Fuel efficiency is further enhanced by regenerative braking in which energy normally lost as heat during deceleration and braking is captured to recharge the battery.

“The Sebring HEV demonstrates how our TTR hybrid system can be adapted to many different types of vehicles,” said Larry Oswald, Vice President and head of DaimlerChrysler’s Hybrid and Electric Vehicle Product Team. “The TTR can be installed in vehicles of different styles and sizes, with front- or rear-wheel drive. This gives us great flexibility as we continue to explore new applications for environmentally-friendly hybrid technology.”
