2017 Camaro ZL1 Beats Previous Generation’s Nürburgring Lap Time

The new 2017 +Chevrolet Camaro ZL1, expected in showrooms by the end of this year, just beat the benchmark set by the last generation ZL1. With a lap time of 7:29.60, it is 11.67 faster faster than the last generation and even beat the last generation Z/28's time of 7:37.9 - which was done on Pirelli P Zero Trofeo R tires, far grippier than the Eagle F1 Supercar used on the ZL1. The car used is unchanged from the one you'll be able to buy, aside from the installation of data acquisition equipment, a roll hoop, and Sparco racing seats with six-point harnesses. Otherwise, the car was production stock and included the following:

Limited Slip Differentials - The Basics

I'm finishing up a comparison post (link to introduction:Intro: Focus RS vs Golf R vs WRX STI vs Evo X) and, throughout the post, I realized that I have to go off topic a lot to talk about how each type of differential changes the way the car drives. As a result, I thought I'd write a separate post to go into more detail before I post the comparison to keep it more focused on the cars and avoid veering off topic too much.

By saying "Limited Slip Differentials" in the title, I am including torque vectoring diffs because, although current conventional terminology treats them differently, a torque vectoring differential is, in essence, a very sophisticated limited slip diff (LSD) that can be manipulated to actively help the car handle better. And while none of the cars in the comparison use open (without help from the brakes) or non-gear mechanical LSD’s, I’ll briefly discuss them so that the post is more inclusive. I’ll only focus on using power to help the handlin…
