The little brother of the M3 on the test bench at CPA

BMW E90 335i

So far, the BMW 335i has been hiding in the shadow of its big brother. But thanks to the targeted map optimization of the CPA PowerBox, the 335i reaches unimagined dimensions. Up to 80 hp and an expressive 104 NM of growth are possible. This means that the BMW with CPA chip tuning sprints even tighter forward than the production version. In the fast lane, on the highway, the BMW is even more fun, but it has not lost its suitability for everyday use in any way, as our test on the country road and in the city shows. Finally, we go to the test bench, where we put the in-line six-cylinder with PowerBox through its paces. We have paid special attention to gear changes under partial and full load, for example.
