F for the newly launched BMW X5 M models (F85) and X6 M (F86) with more powerful M-TwinPower-Turbo-V8-engines Dähler offers performance cures in two stages. Power level one comes with 664 hp at 6,500 rpm or 820 Nm torque at 3,000 to 5,000 rpm - the standard values are 575 hp and 750 Nm. The V8 with an 8-speed M sports automatic transmission comes from a standstill to 100 km /h in 3.9 seconds. The speed limit is then limited to 305 km /h.
From zero to one hundred in 3.8 seconds
In performance level two, the sprint to one hundred takes even one second less. Here the engine even throws 680 hp at 6,600 rpm or 860 Nm at 3,200 to 4,600 rpm into the scales. Here too, however, it ends at 305 km /h. Dähler achieved the increase in performance through newly tuned engine electronics. A map optimization should improve the maximum filling characteristic of the twin-charger. In addition, the Swiss have revised the response of the accelerator pedal and the limitation of the speed increase. According to the company, a 'turbo lag' can hardly be made out. High-performance catalytic converters, stainless steel exhaust systems, hardness and height-adjustable performance chassis, 22- or 23-inch wheels and interior optimizations round off the Swiss performance cure.
