While the C350 CGI BlueEFFICIENCY features a V6, the three new engines are all based around four-cylinder powerplants. Kicking off the new lineup is the 2.2L C220 CDI BlueEFFICIENCY turbodiesel, which is described as the most efficient C-Class ever and generates a peak output of 170hp (125kW) and 295lb-ft (400Nm) of torque. The efficient oil-burner will accelerate the C-Class from rest to 100km/h in a respectable 8.4 seconds, while returning a fuel economy of 49mpg (4.8L/100km) and CO2 emissions of 127g/km.
Next in line is the is the C250 CDI BlueEFFICIENCY turbodiesel, which is rated at 204hp (150kW) and 369lb-ft (500Nm), sends the car to 100km/h in 7 seconds flat and returns a fuel economy of 46mpg (5.1L/100km).
Finally, there’s the new C250 CGI BlueEFFICIENCY petrol model, which also develops 204hp (150kW) but only 229lb-ft (310Nm) of torque. This particular model takes 7.4 seconds to reach 100km/h, while returning a fuel economy of 32mpg (7.2L/100km).
The engines are available in both the Sedan and Estate models but are currently limited to European markets only. Other market launch dates are yet to be announced.
