The Nürburgring Nordschleife doesn’t care the place a automobile is from, how a lot it prices, or what badge it wears. With 73 corners unfold throughout 12.9 unforgiving miles, it’s probably the most sincere check of a automobile’s whole efficiency. And the most recent occasions from Chevrolet’s Corvette lineup make that painfully clear—particularly when contemplating how the BMW M4 CSL has been positioned as one among BMW’s most centered and succesful observe automobiles.
Chevrolet simply confirmed that its upcoming Corvette ZR1X laid down a 6:49.275 lap on the Nürburgring, making it the quickest lap ever recorded by a U.S.-built manufacturing car. Proper behind it was the 1,064-horsepower ZR1, which accomplished its lap in 6:50.763. However maybe probably the most telling comparability comes from the naturally aspirated Corvette Z06, which managed a 7:11.826—nonetheless over six seconds faster than BMW’s greatest.
As a result of the BMW M4 CSL, regardless of being the quickest manufacturing BMW across the Nordschleife, recorded a 7:18.137. And on paper, it’s simple to see why.
Uncooked Specs Inform the Story
Let’s break it down.
| Automobile | Nürburgring Lap Time | Engine | Horsepower | Drivetrain | Curb Weight |
|---|---|---|---|---|---|
| Corvette ZR1X | 6:49.275 | Twin-turbo 5.5L DOHC flat-plane V8 | 1,250 hp | RWD | 3831 lbs |
| Corvette ZR1 | 6:50.763 | Twin-turbo 5.5L DOHC flat-plane V8 | 1,064 hp | RWD | 3,670 lbs |
| Corvette Z06 | 7:11.826 | Naturally aspirated 5.5L V8 | 670 hp | RWD | 3434 lbs |
| BMW M4 CSL | 7:18.137 | Twin-turbo 3.0L inline-6 | 543 hp | RWD | 3640 lbs |
The M4 CSL has lengthy been praised for its precision and composure. However these virtues don’t change physics. It provides up 127 horsepower to the Z06, over 500 hp to the ZR1, and greater than 700 horsepower to the ZR1X. That issues—particularly at a observe just like the Nürburgring, the place energy interprets on to time gained on the straights and uphill sections. Even weight isn’t on BMW’s facet right here. The Z06, regardless of being bigger and mid-engined, is about 200 kilos lighter than the CSL. That benefit, mixed with sharper aerodynamics and a flat-plane crank V8 that revs to eight,600 rpm, makes it no shock that the Z06 pulled off a time that will’ve been headline information if it weren’t fully overshadowed by the twin-turbo ZR1s.
What the Corvette ZR1 Nürburgring occasions present is how a lot the efficiency bar has moved—particularly for American producers. BMW’s M division now finds its flagship coupe nonetheless over 6 seconds behind a naturally aspirated Z06. After all, the M4 CSL isn’t meant to be an influence brute. It’s a meant to supply a steadiness between driving dynamics, steering really feel, and driver engagement. However in terms of lap occasions—the factor automakers publish to show their engineering mettle—BMW’s greatest is behind. For now.
Earlier right now, BMW posted their very own file across the Nürburgring with the M3 CS Touring turning into the quickest touring across the Inexperienced Hell.
All These Information Go Below The “Prototype” Classification
Importantly, all three Corvettes have been pushed by GM engineers, not employed racing drivers, just like how BMW M runs their very own laps. These weren’t one-lap specials working on racing slicks both. Every automobile had U.S. manufacturing specs with security add-ons like a roll hoop, containment seat, hearth suppression, and a six-point harness. The rationale they’re formally listed underneath “prototype” is as a result of they’re not homologated on the market in Europe—not as a result of they have been pre-production in efficiency. The BMW M4 CSL’s lap was achieved with a inventory automobile on Michelin Cup 2 R tires.
