BMW combines dynamics, agility and sportiness in SUV form. The well-known straight-six petrol engine from the M140i produces 360 HP at 6000 rev/min. The PowerBox from CPA boosts the strong X4 with more power of up to 88 HP and 123 NM. Due to map optimisation, variables such as boost pressure or injection quantity are adjusted. This shows the X4 M40i in its best light, and the X4 shines in our tests. The SUV is quite quick; the powerful six-cylinder has plenty of torque in each area. Despite the performance optimisation, the comfortable and sublime driving feeling of a SUV is maintained — uncompromising chiptuning in every aspect.
Let yourself be inspired by a derivation of up to 60 hp and 80 NM, made possible with the specific software of the CPA PowerBox. Various models of the tuning box are available for the M2 Competition.
