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.

Cadillac considering more radical ATS-V

Cadillac is stepping up its performance game with the launch of the new ATS-V and CTS-V, but it's not about to rest on the laurels it removed from its own badge. While it's tipped to launch additional V models in the future, the latest word is Caddy could also come out with an even more extreme version of the ATS-V in the near future. According to Car and Driver, the prospect is on the table: "We might have something down the road that is a little bit more aggressive," chief engineer Dave Leone said, while another source pegged its potential arrival for 2017. It's too early to say what would constitute the more extreme model. The magazine points toward the Mercedes-AMG Black Series as an example. Jaguar took a similarly extreme approach with the XKR-S GT, as BMW has with the M3 GTS. As it is, the ATS-V is offered in both coupe and sedan variants with a 3.6-liter twin-turbo V6 producing 464 horsepower channeled to the rear wheels through a six-speed manual. Cadillac reportedly considered employing a dual-clutch transmission and all-wheel drive, but went the old-school route to avoid excess weight and (no doubt) cost.

2015 Cadillac ATS Coupe favors cleanliness over radical lines

Though you might not know it from looking at vehicles like the XTS and Escalade, if you take a broader look at history, you'll see that Cadillac models have gotten a lot smaller from the tail-finned highway cruisers of old. At least when it comes to coupes, anyway. The Eldorado, in particular, kept getting smaller until it disappeared, its place taken in recent years by decidedly more compact XLR, CTS Coupe and ELR hybrid. What you see here, however, is Cadillac's smallest coupe yet.
Revealed today at the Detroit Auto Show is the new 2015 Cadillac ATS Coupe, the brand's first compact two-door coupe, and the first production car to wear the brand's all-new crest. It shares the same platform and wheelbase as the existing ATS sedan, but packs a wider track and unique bodywork that's decidedly more conservative and less unique in its angular styling than the CTS Coupe that it's likely to ultimately displace in the Cadillac lineup. Styling aside, the all-American luxury marque has engineered the ATS Coupe with a focus on reducing weight to the benefit of both performance and fuel economy, giving it near 50/50 weight balance front to rear with underbody aerodynamic elements helping it cheat the wind.
Buyers will be able to choose between two engines: a 2.0-liter turbo four and a 3.6-liter V6.
