Mercedes-Benz is now offering three new direct injected engines in its C-Class BlueEfficiency models. Two of the three four cylinder engines are diesels while the other is fueled by gasoline. The 2.2-liter diesel is available as a single turbo 170 hp version or a dual turbo 204 hp variant. The diesels produce 295 lb-ft and 369 lb-ft of torque respectively. The gasoline engine is a new 204 hp turbocharged 1.8-liter unit with 229 lb-ft of torque.

The gas engine gets a combined 32.7 mpg (U.S.) on the EU combined driving cycle. The diesels are the cars that really shine on the test cycle with the more powerful C250 CDI getting 42.1 mpg (U.S.) and the 170 hp C220 scoring 49 mpg (U.S.). Even with that kind of mileage, the C220 still runs to 62 mph in a very respectable 8.4 seconds. All three models are available as either sedan or station wagon.

Unfortunately, like BMW, Mercedes has decided not offer any four cylinder engines in the U.S. market in recent years. Hopefully Mercedes, will soon follow Audi's lead and switch from six to four cylinders.

Three newly developed engines with direct injection will make the Mercedes-Benz C-Class even more efficient. They raise performance and driving enjoyment to a new level, while demonstrating exemplary economy and environmental compatibility.
The new engines impress with a low fuel consumption, and therefore exemplary environmental compatibility, while delivering a high output and therefore outstanding driving pleasure. The new C 220 CDI BlueEFFICIENCY saloon, the most efficient C-Class ever, generates 125 kW/170 hp and a torque of 400 Nm from a displacement of 2143 cubic centimetres. This accelerates the saloon from standstill to 100 km/h in 8.4 seconds, yet the combined fuel consumption is only 4.8 litres of diesel per 100 km (corresponding to CO2 emissions of 127 g/km) - the best figure in this category.
The newly developed four-cylinder in the C 250 CGI BlueEFFICIENCY also uses direct injection. It achieves 150 kW/204 hp and offers 310 newton metres of torque. The saloon requires 7.4 seconds for the sprint from 0 to 100 km/h with the new petrol engine. The combined consumption amounts to 7.2 litres per 100 km (CO2 emissions 168 g/km).
