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.

Try the TB12 Method with Tom Brady's fancy Escalade limo

ESPN's 10-part documentary "The Last Dance" recently gave viewers an inside glimpse at the basketball GOAT Michael Jordan's rides. This week, the public has a chance to ogle one of the football GOAT's vehicles, and it's significantly different from any of the car's MJ drove. While No. 23 was most often seen in speedy sports cars, Tom Brady just listed a Cadillac Escalade limo for $300,000, or best offer. Posted by Becker Automotive Design, the builder of the vehicle, this is a 2018 Cadillac Escalade ESV Mobile Office. The Escalade has been stretched by 20 inches, including 10-inch lengthened rear doors, and it features additional headroom thanks to a five-inch extended-height roof. Inside, the rear row facing forward features three regular seats upholstered by Becker. The added middle row that looks toward the rear of the vehicle features two six-way power reclining VIP seats with electric leg rests. The VIP view sees a 32-inch HD LCD TV, while a 12-inch screen is mounted behind the VIP seats. Additionally, the Escalade has a Savant remote-control audio-visual system, two aviation-style folding tables with burlwood veneers, and a "high-end mobile internet router that allows for multiple service providers." “Parting ways with my Becker ESV wonÂ’t be easy," Brady said in a provided press statement. "From day one it became my sanctuary from the outside noise. I took pride in picking out all the customizations of the ESV; from the trim of the seats to the color of the rug. With such limited time in my busy schedule, the ESV gave me those extra minutes to study my play book, make phone calls and be with my family. Immediately my productivity went up and my stress came down. I hope the next owner will take great care of her; she will always be a part of the Brady family.” P.R. speak aside, the Cadillac is surprisingly cheaper now than it was when Brady purchased it. The ESV originally sold for $350,000, and with 13,000 miles on its clock, it is now listed for $300,000, or best offer. Considering Brady is the greatest football player of all time, no debate, and is set to have his own nine-part ESPN documentary, we wouldn't be surprised if the best offer is higher than the asking price. Maybe he'll take the money and trade up for a Lexani Escalade Mobile Office. Related Video:

GM recalling Cadillac ATS, XTS, Chevy Impala over faulty brake lamps

General Motors has issued a recall covering 1,627 sedans over faulty brake lamps. Both the 2013 Cadillac ATS and XTS are affected by this problem, as is the 2014 Chevrolet Impala.
According to an official National Highway Traffic Safety Administration report, "the brake lamps may intermittently flash without the brakes being applied and the cruise control may disengage" on these vehicles. The report does not state that the brakes themselves are faulty, but rather that "if the brake lamps flash when the vehicle is not slowing, a following driver may not adjust vehicle speed when the vehicle is in fact braking."
This marks the first recall for the 2013 Cadillac ATS, as well as the recently introduced 2014 Chevy Impala. In late 2012, over 12,000 Cadillac XTS models were recalled due to a head restraint issue.
