180, 200, 250 CGI engine M270 / M274


The 4 cylinder engines M270 and M274 are available with two different displacements, 1.6 liters and 2.0 liters turbocharged direct injection. Essentially they are the same engine, the M270 is offered in Mercedes models with FWD fitted transversely, the M274 in the RWD models and fitted longitudinally. 

With our additional electronic module we achieve a low-cost and easy fittment performance increase in all cases for those M270 and M274 engines.

All listed performance figures are approximate values. They depend on vehicle-specific details such as the vehicle type, equipment, tare weight, rear-axle ratio, wheel-tyre combinations, transmission type and aerodynamic equipment of the specific car. Figures about performance increases and/or performance kits are to be understood as average values. Test-dependent divergences of +/- 5% are possible. Figures about the overall performance of changed factory engines through performance increases and/or performance kits are based on the manufacturer´s data listed in the vehicle regristration document. They can vary by +/- 5%. LOEWENSTEIN does not warrant any further reduced performance of factory engines. Specifications are subject to change without prior notice.
