You might not have noticed that the Mercedes-AMG GT R and Chevrolet Corvette Z06 have a lot in common. They're both front-engined, two-seat, rear-drive sports cars that have forced-induction V8s and rear transaxles. They even offer as an option for track use. And as we can see from these track test videos, they set remarkably similar lap times. brought together the two super coupes together on track on two separate occasions, and the results are fascinating.
If you need a refresher, the Z06 makes 650 horsepower and 650 lb-ft of torque from its 6.2-liter supercharged V8, which in this case, sends power to the rear wheels through a seven-speed manual transmission. The AMG GT R makes just 577 horsepower and 520 lb-ft of torque from its twin-turbo 4.0-liter V8, but its engine is paired up with a fast-shifting seven-speed dual-clutch transmission.
The first test was done on Hockenheim's Club circuit layout, which features a bunch of tight turns and not many straightaways. Here, the GT R was able to best the Corvette by two-tenths of a second thanks to its fast-shifting gearbox and nine-stage traction system.
The second test, held at The Ring of the Rhine in France, featured more sweepers and open corners, giving an advantage to the more powerful Z06. It was able to lap the course three-tenths of a second faster than the AMG.
It's worth noting Car and Driver set a faster time in the GT R versus the Z06 during , so the outcomes seem track-dependent. One thing's for sure though: The Z06 remains one hell of a value proposition.
