A compressor is a parasite. Although it presses compressed air into the combustion chambers of the engine by means of rotors, this increases its performance. But he taps up to 15 percent of it for his own drive. Because that harms fuel consumption, Mercedes is converting the four-cylinder petrol engine from v on intake manifold injection with a compressor to direct injection with a turbo.
The performance remains unchanged, the consumption drops
The 180 CGI is the new basis in the C-Class. Although it is combined with the slow five-speed automatic transmission and no longer delivers 156 hp, the 180 CGI accelerates 1.5 seconds faster to 100 km /h and consumes 0.4 L /100 km less than the 180 K with six-speed gearbox.
The 1.800 combines a lively temperament with good running smoothness, only the turbo whistling it doesn’t like to resist. The basis is the wrong name - no more engine is needed in the T-model. It continues to impress with its assiduous comfort, high driving safety and extensive accident prevention, optionally also with Pre-Safe. The system tugs on the seat belt every time it starts so that the customer knows what he paid 393 euros extra for. Half of them can be refinanced with the CGI - adjusted for equipment, it costs around 200 euros less than the old K.
