In test: Mercedes SLK 250 CDI

Even more sportiness with the CPA PowerBox

The Mercedes SLK 250 CDI is the first in its class. Long before the developers were afraid to pack such a diesel engine in a roadster. But nothing ventured, nothing gained. By the sporty look of the roadster, one can hardly imagine how fuel-efficient the small is. While it has innately a high torque, but a little more horsepower would not do harm, in our point of view. By PowerBox Nitro with specially developed software, a power increase of 29% could be achieved. Thus the Stuttgarter will get more lively and sporty.
