The Porsche 911 GT3 is a lightweight rear-wheel drive sports car from Germany with plenty of power – the same goes for the BMW M4 CSL, though, so which of these two cars is faster off a dig or a roll?
Matt Watson and Carwow try to answer those questions in a new video on their Youtube Channel showing a series of drag races between these two Germans sports cars.
On paper, the BMW M4 CSL and Porsche 911 GT3 are equivalent to each other
The BMW M4 CSL weighs just under 3,600 lbs. It gets its power from a 3.0-liter twin-turbo inline six-cylinder engine and an 8-speed automatic transmission – the powertrain’s total power is 550 horsepower and 479 ft-lb of torque.
The Porsche 911 GT3 has a 4.0-liter flat-6 engine and a 7-speed dual-clutch transmission that produces a combined 510 horsepower and 346 ft-lb of torque; despite the lower power figures, the Porsche has a significant weight advantage, as it hits the scales at a much lighter 3,163 lbs.
The results of the race between the M4 CSL and the 911 GT3
In the race, the Porsche takes the early lead and passes the 1/4 mile with a decisive lead. Matt Watson says the BMW starts in 2nd gear, and even with stability control turned off, it still reduces power at launch to limit wheel spin.
For the second race, the Porsche wins again because the BMW has even more problems with the traction control systems.
They participate in several more races, but the results are always the same; the M4 has a problem getting a good launch, while the rear engine layout of the 911 gives it good traction off the line.
Then it’s off to a series of roll races: the first starts with both cars going 50mph, with the transmissions in their sportiest automatic settings.
The BMW’s gearbox slows down at the start of the race and this allows the Porsche to take the lead, but the M4 closes the gap and narrowly loses at the finish.
In the second rolling race, both cars are put into manual mode – this change in settings allows the BMW to get a better start as it runs away from the Porsche.
The two German coupes then come together for a final roll race: it starts at 40mph with each car in second gear – the driver of the 911 GT3 misses a gearshift and the BMW pulls away and wins.
