The Chrysler Citadel

Technology in Action: Running Clean

Electricity plays a key role in the hybrid Chrysler Citadel, which offers environmental efficiency with V-8 performance. A gasoline-fed 3.5-liter V-6 engine powers Citadel's rear wheels, while the front wheels operate on electric motors. The efficiency delivered by the electric motors allows for more power to drive the rear wheels.

The V-6 delivers 253 horsepower, with an extra 70 horsepower coming from the electric motors. Engineers see Citadel offering the performance of a sport utility vehicle but with improved fuel economy. So while Citadel carries a V-6 engine and fuel economy, it delivers V-8 power and torque.

Citadel is the first DaimlerChrysler concept car that emphasizes performance. Past DaimlerChrysler hybrid concept vehicles include the Patriot racecar, Dodge Intrepid ESX and Dodge Intrepid ESX2.

"While we're not claiming to have already developed the perfect diesel engine, we are claiming that diesels have a significant future in the passenger car and truck industry," Robertson said.
