For the German Tuner insidePerformance from Einhausen (near Mannheim) 555hp and the already sporty BMW X6 M series stock-look are not enough. An massive improvement in optics, engineering and motor performance ensure that the 2,5 tons car does not even fear a Porsche or Maserati.

By means of engine and ECU optimization, 200 cells sport catalysts and various technical tricks, insidePerformance brought the 4,4, liter V8-biturbo engine to more than 700hp and over 850Nm torque. The repeal of the speed limit lock provides even more overtaking fun. The increase in performance is also based on the modified exhaust with a new engineered stainless steel flap-controlled 3 Inch exhaust-system. 

The driver can decide whether the V8-aggregate should sound “athletically pithy” or “martially loud”. Finally, the surface of the four 90mm strong tailpipes is individualized with an up to 1000 degree temperature resistant special coating in various available colors – here in “Cobalt Gray mat”.

The whole exterior of the insidePerformance BMW X6 M “STEALTH” is very special. A harmonizing wide body kit, based on the wide body parts made by AC-Schnitzer, covers the cladding of the rear doors, the fenders and the broadening on the front and rear bumpers. In combination with the deep concave drop-center rims, the BMW X6 M becomes 4 inches broader.
