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 ATS coupe and sedan get Midnight Editions

Horror stories and fairy tales make a mint by having the scariest things happen at midnight, but automakers make a mint by marketing midnight. Chevrolet busted out a Silverado Midnight Edition early this year, followed shortly thereafter by an Impala Midnight Edition. In between those two we got the Cadillac CTS Midnight Edition, and now comes an ATS following in the zero-dark-thirty tradition, according to GM Inside News. The ATS Midnight Edition will add $1,695 to the sedan price and $600 to the coupe. For that cash outlay you get black chrome on the grille, around the windows, and on the rear fascia, 18-inch "After Midnight" wheels, "sueded microfiber" trim on the steering wheel and shifter, plus the Cold Weather Package with a heated steering wheel and heated front seats. Just those few exterior changes make a big difference up front, increasing the appeal and aggression of the sports sedan without being ostentatious. You can't go dark with just any old ATS, though. The package is limited to rear- and all-wheel-drive versions of the Performance trim. And the color palette is reduced to four hues: Crystal White Tricoat, Red Obsession Tintcoat, Phantom Gray Metallic, and Black Raven. The three possible interior combos are Light Platinum with Jet Black accents, Morello Red with Jet Black accents, and Jet Black with Jet Black accents.

2017 Cadillac XT5 shows off its new metal in LA

Cadillac is in the midst of a comprehensive production overhaul, and few of its new arrivals will be as pivotal as the new XT5. Replacing the old SRX, the XT5 was revealed in the metal here on the floor of the 2015 LA Auto Show. Joining the new CT6 under Caddy's new naming scheme, the XT5 represents GM's assault on German competition like the Audi Q5, BMW X3, and Mercedes GLC, Japanese rivals like the Lexus RX, Infiniti QX50, and Acura RDX, and its own cross-town nemesis, the Lincoln MKX. And to better fend off their advances, the new XT5 promises marked improvements over its predecessor in every way. The model you see here is, to our eyes, handsomer than the model it replaces, adopting the Art & Science brand's latest design cues. It offers a fresh cabin space loaded with the latest equipment. And it weighs a solid 278 pounds less than the outgoing SRX. Power still comes from a 3.6-liter V6, paired to an eight-speed automatic transmission with available all-wheel drive. 310 horsepower and 270 pound-feet of torque keep it going, which ought to help it keep pace with the competition. We're looking forward to seeing how it drives in due course, but in the meantime, you're invited to view our live photos from the floor of the Los Angeles Convention Center in the gallery above.
