Jeep Grand Cherokee Bluetec Concept Auto Show Photo

DaimlerChrysler showed a current-generation Grand Cherokee concept SUV with a new 3.0-liter I-4 turbo diesel engine (not available in the U.S.) to show off the potential of some of its newest technology. Called BLUETEC, the system injects ammonia into engine emissions to significantly reduce the nitrogen-oxide levels from diesel exhaust. This exhaust treatment in the catalytic converter turns the harmful NOX chemicals into simple nitrogen and water vapor. These next-gen innovations have the potential to meet the most stringent emissions regulations worldwide, as well as emissions standards in all 50 states. The Jeep Grand Cherokee BLUETEC Concept stores the liquid charge in the rear tub where the spare tire is usually housed. Depending on technology combinations, a tank full should last up to 10,000 miles, but would have to refilled, most likely by a dealer, when low. Look for more BLUETEC technology systems on Mercedes-Benz diesels first, then branching out other DaimlerChrysler brands.
