German tuning specialist Inside Performance has revealed its Stealth program based on the mighty BMW X6 M.
Underneath the hood, IP fits a full stainless steel exhaust system including manifolds and 200 cell catalytic converters, along with its remapped ECU software. Those tweaks see output from the 4.4-litre biturbo V8 powerplant rise from 408 kW (555 hp) and 680 Nm of torque to 522 kW (700 hp) and 850 Nm. The speed limiter was also disabled.
Visually, the SUV wears a pixelated camouflage foil wrap, an AC Schnitzer wide-track body package adding 4-inches to the vehicle’s width, twin bonnet vents and matte black 22-inch Vorsteiner wheels wrapped in 295/30 and 335/25 rubber.
The factory suspension has been replaced by an adjustable coilover kit from KW Automotive, while the interior gains a digital display to monitor such conditions as temperatures and boost pressure.
