VIDEO: BMW M4 CSL vs Porsche 911 GT3 RS vs Corvette Z06—Hagerty Test

The M4 CSL is the fastest BMW on the Nürburgring, proving it to be the fastest and most capable BMW of all time. However, it comes at a difficult time for hardcore, track-oriented BMWs, as the competition is tougher than ever before. The M4 CSL competes against cars such as the Corvette Z06 and the Porsche 911 GT3 RS. In this new video from Hagertywe get to see how well, or not so well, the M4 CSL fares against such fierce competitors.

In the video, Randy Pobst drives every car around Willow Springs in the same conditions on the same day to see which one is the fastest. They also had telemetry equipment on board to see how fast each car was going through each corner, their braking forces and lateral g-forces. So it was easy to see which car was more capable through each turn.

Every car is drastically different, in layout, engine type, layout and price. However, each car is the most capable track product each brand has to offer.

The BMW M4 is a front-engine, rear-wheel drive sedan-based coupe with a 3.0-liter twin-turbo I6 producing 543 horsepower and 479 lb-ft of torque and an eight-speed automatic torque converter. The American Corvette Z06 is a mid-engine, rear-wheel drive supercar with a 5.5-liter naturally aspirated V8 producing 670 hp and 640 lb-ft and an eight-speed dual-clutch transmission. Finally, the Porsche 911 GT3 RS is a rear-engine, rear-wheel drive sports car with a 4.0-liter naturally aspirated flat-six with 518 horsepower and 342 lb-ft and a seven-speed dual-clutch transmission.

Two of the three cars are relatively lightweight, as the M4 CSL tips the scales at 3,580 lbs and the Z06 checks in at 3,670 lbs. However, the 911 GT3 RS is actually lightweight, weighing just 3,211 lbs. The Porsche’s low curb also has the most extreme aerodynamics of the two cars, as it not only has a massive fixed rear wing, but also an active DRS-style flap. The Z06 has a small wing and impressive front aerodynamics, but it can’t match Porsche’s. While the M4 CSL has a barely there integrated ducktail spoiler and a small front lip. So in terms of aerodynamics, the Bimmer has a huge disadvantage.

The M4 CSL also had a huge tire disadvantage. While the Porsche and Z06 wore Michelin Pilot Sport Cup 2 R tires (which are hardly street-legal track tires) for this race, the M4 had CSL Pilot Sport 4S tires, normal high-performance street tires. BMW does offer Cup 2 Rs on the M4 CSL, but couldn’t supply them for the test (it sometimes happens, as manufacturers can’t always accommodate every journalist’s request for various reasons).

So how did the three cars stack up in Willow Springs, with Pobst behind the wheel? I don’t think I’m spoiling it by saying the 911 GT3 RS won the test, because that’s pretty obvious. But how he won and how well each car performed is really surprising, so it’s worth checking out. To look at.
