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 reveals stretched ATS-L in China

In the market for a new Cadillac, but need more space than an ATS can afford? Then you'll want to look at the larger CTS. Unless you live in China, where buyers - often chauffeured instead of driving themselves - seem to prefer a long-wheelbase version of a smaller sedan than upgrading to a larger one. For those buyers, Cadillac has released the new ATS-L.
Based on the existing ATS sports sedan, the ATS-L offers an extra 3.3 inches of rear legroom over the model we get here. As a result, the ATS-L stretches its wheelbase to 112.5 inches and its overall length to 186 inches, while riding a quarter-inch lower than the standard-wheelbase model, which itself was recently updated. That places its length in between the regular ATS and the CTS available Stateside.
Otherwise it's essentially the same sedan, but appears to ditch the base 2.0-liter four to offer either the 2.0-liter turbo four or 3.6-liter V6. Of course this model, produced locally for the Chinese market, isn't likely to make the transpacific voyage to US showrooms, so American buyers will still have to choose between the standard ATS, the larger CTS or the even larger XTS.

Corvette's Performance Data Recorder headed to other cars, will Cadillac ATS-V be first?

For 2015, the Chevrolet Corvette Stingray gained a novel piece of high-performance technology: The Performance Data Recorder. This trick system combines video from a front-mounted camera with in-car data and GPS information to help drivers record and study their lap times, complete with data overlays. While it's a clever tool for track days, it's also finding popularity as a built-in dash cam of sorts. To this point, the technology has been a Corvette exclusive, but General Motors' executive vice president of global product development, Mark Reuss, has confirmed to Autoblog that it will soon be available in other vehicles.
At a media luncheon on Thursday, we asked whether GM was keen to expand usage of the technology to other models, and if we could expect to see something soon. Reuss coyly replied, "What's soon?" When we suggested the 2016 Cadillac ATS-V (which is scheduled to debut at next week's LA Auto Show), he replied, "There will be other uses, and it won't be that far away. How's that?"
Certainly not an outright confirmation, but we wouldn't be at all surprised to see the next high-po Cadillac roll under the klieg lights at the Los Angeles Convention Center next Wednesday brandishing more than just 450 horsepower.
