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.

2016 Cadillac CTS-V to hit dealers this summer, start at $83,995*

Cadillac has announced pricing for the 640-horsepower CTS-V, and not only will the new super-sedan outgun its heartiest German rivals, it'll undercut them on price, too. Kicking off at $83,995 (not including a $995 destination charge), the CTS-V is nearly $10,000 less than the 560-hp BMW M5, almost $18,000 less than the 577-hp Mercedes-Benz E63 AMG S 4Matic, and is nearly $25,000 less than the 560-hp Audi RS7. So in case you were wondering, yes, the CTS-V will continue to be one of the auto industry's very best high-performance bargains in its third generation. "V-Series represents the pinnacle of Cadillac, a brand that now makes drivers' cars at the highest level," Cadillac's head honcho Johan de Nysschen said in a statement. "The new CTS-V is essentially two cars in one: a luxury sedan with sophisticated road manners and a track-capable sports car with awe-inspiring performance. This type of car is exclusive, the domain of the few who can access this level of incredible capability. V-Series matches or overtakes the finest cars in this elite class, while being more accessible." As for when you can get your hands on bargain-priced beast, dealers are now accepting orders, with deliveries slated to begin late this summer. Scroll on down for the official release from Cadillac.

Not only are the new V-Series cars elevated in terms of performance, they now reach a broader spectrum of drivers by presenting two distinct personalities, size categories and price points. With a top speed of 200 mph and 0-60 performance in 3.7 seconds, the CTS-V is the most powerful car in Cadillac's 112-year history. The 2016 CTS-V is priced from $83,995.
