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 is doing a 'second installment' of the CT6-V for $92,790

After being all but certain the Cadillac CT6 would begin pushing American daisies June 1, the brand said "the CT6 was never meant to be fully on the chopping block." The same day we got that news, Cadillac began taking pre-orders for the CT6-V. Limited to 275 units and costing $88,790 after destination, orders came in so quickly that order books closed only hours later. Turns out the phrase "275 pre-order slots" was another slight miscommunication. Cadillac has announced continued production of the CT6-V, this time costing $92,790. In February, Cadillac Society confirmed with the automaker that the 275 figure only applied to pre-orders. It isn't clear how many CT6-Vs will be built in what the brand calls the "second installment," but it is clear that buyers who didn't get in early will pay more. Cars Direct was privy to a letter sent to dealers that said pre-order buyers "were rewarded with a special introductory offer by quickly raising their hand." Those slow on the draw have hopefully used the extra time to fish another $4,000 from their pockets. The elevated price buys the same car that was $88,790 two months ago - nothing has changed but the bottom line. The new MSRP puts more distance between the hot CT6-V and the $89,290 CTS-V. Conversely, the CT6-V with a Blackwing V8 beating 550 horsepower and 627 pound-feet of torque is now just $4,000 less than the coming Platinum V8 trim, which costs $96,790. That Platinum version gets a detuned Blacking putting out 500 hp and 553 lb-ft. The vague phrase "second installment" phrase makes us think Cadillac's not committing to a number so it can cap production at will depending on how this more expensive go-round fares. Still, it's good news for anyone who wanted the sedan new and didn't hit the buzzer quickly enough in January. As if all that weren't surprising enough, GM Authority reported that there's a second-gen CT6 in development. The outlet's sources say the new sedan will move to GM's VSS-R platform, the modular architecture that will replace both the Alpha and Omega platforms. The platform initialism stands for Vehicle Set Strategy - Rear-wheel drive. The car even has a codename: 7ESL, where 7 represents the architecture, E the segment, S the sedan body style, and L the Cadillac brand. Looks like the CT6 will be nothing but surprises this year.

Cadillac issues stop sale on ATS to recall 82k units

Cadillac is issuing a recall on 82,620 examples of the 2013-2016 ATS worldwide to fix a compliance issue with the sunroof controls. Until a service bulletin goes out to take care of things, there's also a stop sale on the luxury compact in the United States, The Detroit News reports. Of the affected models, 63,665 are in the US, according to a statement sent to Autoblog, and 7,922 of them are in Canada. The problem is actually the same issue as a recall on nearly 59,000 examples of the 2013-2015 ATS in the US in February. In them, the controls for the tilt and slide of the roof aren't recessed enough to meet government standards for the force necessary to operate the buttons. The Feds believe that someone could accidentally activate the auto-close and potentially be at risk. At the time, Cadillac dealers installed a new trim plate to add the needed clearance. In the latest update, the company is adding the 2016 model year, and according to The Detroit News, 70 percent of the cars from the original campaign also need another new trim plate. Unsurprisingly for such a minor defect, there are no known crashes, injuries, fatalities, or customer complaints related to this issue, according to the announcement by General Motors. Cadillac ATS Statement: General Motors is recalling 63,665 Cadillac ATS sedans in the United States from the 2013-2016 model years because the power-operated roof panel systems on these vehicles will auto-close when the non-recessed portion of the "Slide" or "Tilt" switches are pressed and the roof panel is open. Because these switches are not fully recessed, they can be actuated with less force than required to comply with applicable federal standards. GM knows of no crashes, injuries or fatalities related to this issue and has received no customer complaints. The total population of the recall including Canada, Mexico and exports is 82,620.
