The power sedan in the test at CPA

Mercedes E-Class (W213) AMG E63 4MATIC

With the CPA PowerBox, you get a major extra power for your Mercedes E-Class. The engine-specific software brings a proud power increase of up to 101 hp and 132 Nm. The extra power turned out in our everyday tests with the Stuttgarter. The E-Class was able to shine with our PowerBox on country roads, on steep roads, on the highways, on the motorway and in overtaking. The combination of PowerBox and PedalBox - our Connective System - brought additional sportiness. Convince yourself. With the CPA Connective System you have your power in your own hands.
