How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.

2015 Cadillac ATS Coupe

Cadillac has become a very, very different company since the dawn of the new millenium. Its turn-of-the-century lineup, consisting of staid offerings like the Seville, DeVille and Eldorado, represented the Old Cadillac. These cars were plagued with Old GM quality issues and catered to a more elderly audience. Since the company's Art and Science design language arrived, though, we've seen Cadillac flesh out its lineup in a big way, introducing notable and (so far) enduring products, like the the CTS, SRX and most recently, the ATS.
With the CTS tackling the 5 Series segment and the SRX duking it out with the Lexus RX and its classmates, the ATS has been left with the tough task of battling the BMW 3 Series, Audi A4 and Mercedes-Benz C-Class, among others. Critically, at least, it has excelled in this role, but it's still working on finding its feet sales-wise. On paper, broadening the model range by adding a two-door personal luxury coupe could help.
After a week with the ATS Coupe, though, we've found a car that, while retaining the standard model's excellent driving character, doesn't quite offer enough visual excitement to stand up to other cars in its segment.
