Mercedes new four-cylinders engine

Recently Mercedes-Benz has unveiled a new four-cylinder diesel engine that has a balances emission, fuel economy and performance. The top-of-the-line 2.1-liter oilburner is producing 204 hp and 368 lb.-ft. of torque, or around 20-percent more than its predecessor, while returning better mileage and reducing emissions by over 10-percent. When fitted in the new C-class (250CDI) it's able to make the run to 60 in 7.7 seconds while getting 46 mpg.

The other upcoming C-class models will include the 220 CDI and 200 CDI, producing 170 hp and 136 hp respectively. The boost in performance and fuel efficiency comes from the use of new twin-stage turbochargers, more efficient exhaust recirculation, intercoolers, injection systems and a revised common-rail setup.
