F10 M5 Dominates Runway Race Against Porsche’s Best
This tuned F10 M5 takes a Porsche 911 GT3 RS to school in a runway drag race.
Porsche’s lightweight 911 GT3 RS track-day hero wasn’t really built for the drag strip, but with a 500-horsepower naturally aspirated 4-liter flat-six engine, plenty of traction-improving weight over the rear wheels, and a properly impressive launch control system, it’s still capable of low-11-second sprints up the quarter-mile. In stock form, BMW’s super-saloon has around 550 horsepower from a 4.4-liter turbocharged V8, which sees quarter-mile jaunts just a few tenths of a second behind the GT3 RS. This BMW is not exactly stock, however.
According to the owner of the F10 M5, this car has been fitted with a few aftermarket components to pump that power figure up above the 600-horsepower mark. The exhaust has been augmented with a set of Supersprint downpipes, and an Akrapovic Evolution catalyst-rearward muffler system for optimal flow. Presumably, the flow on the intake side has also been opened up a bit. To keep that extra air flow in check and dump in a bit of extra fuel, the ECU has been swapped out for one that has been fettled by ESS Tuning.

Now, in the case of the GT3 RS, it still might have won this race if it simply had the rear wing removed for this exercise. That downforce-inducing aero aid becomes a detriment to outright speed in the form of drag. On a road course, the top-speed reduction is negated instantly by the increased speed you can carry through the corners, but on a drag strip there is little-to-no benefit. Being that this race occurred when both cars were already in motion, the GT3 RS’s weight and traction advantages were also negated. From a “dig,” the 911’s traction control would have given a distinct advantage off the line.
