They have a huge horsepower difference, but it’s hard to tell from watching these races.
There is also the possibility that Porsche may be under-rating the 911. reports suggest upwards of 480 horsepower (358kW) in turbocharged 3.0-liter flat-6. Although it’s still below the Camaro’s power, speed is only one component. You can’t make it go if you don’t have power. The Carrera’s rear engine configuration gives it an advantage. Official statistics from Chevrolet and Porsche show that these cars are actually quite similar in straight-line performance. This is on paper. We all know that statistics don’t always translate into real-world results.
This is evident in the first race, where the Carrera completely destroys the Camaro. Even with launch control enabled, the unprepped surface for the race doesn’t allow for ZL1’s powerful torque. Although the 911 launched much more smoothly, the Camaro lost some ground towards the end.The second race involves a standing launch launch but no launch control. A third and final race, with a rolling start, removes the problem of traction-at launch completely. In these two races, does the Camaro’s horsepower advantage show? The video will tell the story, but here’s a teaser. The outcome is much closer than one might expect.
