The new Mercedes E400 (W212) on the test bench

CPA Chiptuning had the opportunity to test the new Mercedes E-Class on the test bench. The six-cylinder petrol engine with its biturbo already brings a mighty 333 hp to the road in series output. But the engineers at CPA were sure that they could still get something out of the Mercedes E400 and we proved that. Thanks to the specially developed software, the Stuttgart-based company receives 65 hp more power. This corresponds to a performance increase of 20%. Now, thanks to the PowerBox from CPA Chiptuning, the Mercedes has almost 400 hp and is almost unstoppable.
