With a twin-turbocharged 4.4-liter V8 that delivers 592 HP and 553 lb-ft (750 Nm) of torque, the current BMW M5 is an absolute weapon. This example, though, is even more remarkable.

You see, this M5 comes from tuning company Noelle Performance where it has received custom software to turn it into a ballistic missile. All up, it has 850 HP and 740 lb-ft (1003 Nm) of torque and both of those figures have been achieved without any mechanical modifications.

Unlike many tuning companies who simply slap on ‘piggyback’ chips to increase performance, Noelle Performance developed its own software that ensures the engine has much more power than stock while still working harmoniously with the differential, transmission, and adaptive suspension.

The result is a car that can reportedly reach 62 mph (100 km/h) in a staggering 2.2 seconds thanks to the huge power gains and BMW’s insane launch control and all-wheel drive systems.

Power From The Factory: The BMW M5 Competition Is So Fast It Warps Time And Space

Making this particular M5 tune all the more impressive is the fact that it is comes with a warranty. If an M5 from Noelle Performance experiences some kind of powertrain component failure that BMW won’t cover due to the modifications, the tuner will fix it free of charge within the duration of the original factory warranty. Noelle also works hand-in-hand with BMW and notifies the car manufacturer of any vehicles that it modifies.

Buying the tune sets customers back $3,699. Sure, there are cheaper tunes on the market, however they don’t give you the peace of mind of knowing that the car is still under warranty while delivering 850 HP, of nearly 260 HP more than stock…
