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.

Off-road Cadillac Escalade adds some extra bush country capability

So, you're a dyed-in-the-wool General Motors fan, but like the notion of a machine like the Hennessey Velociraptor. We have good news for you. Behold the Aria Coachworks XPLORE Cadillac Escalade. For a modest fee, Aria will outfit your Escalade with a custom suspension, BF Goodrich all-terrain tires wrapped around aluminum wheels, a Warn winch and a special exhaust. There's even a snorkel option for those of you with aspirations toward deep water crossings. Consider yourself warned, however: unlike other GMT900 SUVs, the Cadillac only has an all-wheel drive system, not the more rugged four-wheel drive setup of the Chevy Tahoe and GMC Yukon). Outside, the luxury SUV gets matte paint, black chrome trim, XPLORE power running boards and a roof rack system.
The interior also receives a few fun changes as well, but we're more interested in the fact that buyers can snag a power roof top tent. You know, in case you need to camp out at Best Buy for the PS4. There's also a matching camp trailer and, our personal favorite, a matching BMW GS motorcycle. Bikes not your bag of tricks? That's fine. Aria will also sell you a matched Airstream trailer or Old Town wooden canoes. As much as we want to hate this, we love the notion of bashing through the woods in a $100,000 Cadillac battlewagon with our GS in tow. Check the press release below for more information.

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.
