The title of the biggest bruiser in the BMW range these days is being heavily disputed between the BMW X5 M and its brother, the X6 M. Basically, they are the same car but while the former is the more practical choice, the latter is a bit more aggressive. That said, depending on what you prefer, the choice is yours, but for some the X5 M makes more sense as it is also a bit cheaper.
Of course, when looking at cars that start at over $100,000, the $2,400 difference between the two might not be decisive in the end. What we’re here to show you though is certainly not a stock BMW X5 M. This is the G-Power version of it and it comes with some drastically improved figures, to say the least. The stock S63 revised engine makes 575 HP and 750 Nm (552 lb-ft) of torque which are enough to send the all-wheel drive monster up to 100 km/h (62 mph) in 4.2 seconds. Top speed is normally limited to 250 km/h (155 mph).
The engineers at G-Power don’t really care about speed limiters though and they infused the 4.4-liter V8 with even more boost. Changing the ECU map and upgrading the turbos, the German tuner managed to squeeze 750 HP out of its engine bay. They also had to change the downpipes and the whole exhaust system to better handle the new parameters. The car’s torque figure now reaches 980 Nm (723 lb-ft) which allows the M SUV to be even faster off the line.
To top everything off, the claimed top speed increased to over 300 km/h (186 mph) which is actually frightening. Furthermore, the 1/4 mile run can now be done in 11.5 seconds. Considering the sheer size of the thing, these figures are absolutely mind-boggling. In case they may be a bit too much, other options are also available at G-Power, taking the S63 engine up to either 650 or 700 HP.
