CPA tests the Porsche 911 Carrera 4

With the CPA PowerBox, your Porsche will mutate into a true high-flyer. Thanks to the extra power of up to 20% and in combination with the CPA Connective System, the Porsche accelerates even more agilely and even amazes our experienced engineers with the brute power of the 6-cylinder boxer biturbo. Thanks to the chip tuning from CPA, the Porsche 911 unfolds its full potential and delivers up to 443 hp and 539 NM. A result that is impressive.
