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 CTS wins 2014 Motor Trend Car of the Year [w/video]

For the second time, the Cadillac CTS has been named Motor Trend's Car of the Year. After winning the COTY crown for 2008, the new-for-2014 CTS outdid the other two finalists for Car of the Year honors, the Mazda3 and its corporate cousin, the Chevrolet Corvette Stingray.
What's notable about the Caddy's victory, though, is how it simply brushed off its competition. Both the Mercedes-Benz E-Class and BMW 5 Series failed to make the finalist's bracket, leaving the CTS to claim victory. "It had to beat [Mercedes and BMW] on style, on performance, on comfort, and on quality. It has," Motor Trend said in its COTY recap for the CTS.
The team at Motor Trend praised the CTS chassis, calling it "fantastic," and citing weight advantage the Caddy has over the competition. There was also praise heaped on the car's engines, with the 2.0-liter, turbocharged four-cylinder getting nods of approval from the MT team. The team also raved about the VSport model and its twin-turbocharged V6, magnetic shocks and other performance accoutrements.

2015 Cadillac Escalade

Cadillac has been an interesting story in the auto industry over the past several years. Its comeback bid may be well over a decade old, but it's only recently that the Wreath and Crest has transformed from the auto industry's retirement home into its hot new thing. Today's Cadillac is a powerful marque working to instill passionate design, sound driving dynamics and cutting-edge technology into each model it builds, with vehicles like the ATS and redesigned CTS leading the charge.
Now, its latest model has arrived. This fourth-generation Escalade is among the most important new Cadillacs since the division's renaissance kicked into high gear. It's the brand's de facto flagship, and the first vehicle many young people think of when hearing the name "Cadillac." In the past, the Escalade was the chosen vehicle of the rich, flashy and famous. It's suffered over the past few years, though, particularly as new and more luxurious competitors have come to the fore.
With this latest redesign, General Motors is aiming to retake the spotlight as purveyors of the market's premier luxury SUV. To find out if it's been successful, I ventured down to the South Carolina Lowcountry to test the all-new 2015 Escalade.
