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.

Weekly Recap: Lincoln Continental serves up the style, Cadillac CT6 delivers the substance in New York

Lincoln and Cadillac grabbed the spotlight this week at the New York Auto Show in a dramatic fashion that evoked the brands' glory days. America's two luxury carmakers went toe-to-toe with their glittering reveals and plans for ambitious expansion. Both were selling their technology, style and the promise of a better future. Cadillac vs. Lincoln. At the Javits Center, 2015 seemed a lot like 1956. Neither company was interested in drawing comparisons with the other, which is fair, and accurate. They're in vastly different places in terms of sales and the pace of their turnarounds, but they hope to reach the same eventual destination at the pinnacle of the luxury-car world. Lincoln used the element of surprise to great effect with the Continental concept. A production version is still at least a year away, and the company was vague on details. Officially, we don't even know if it is front- or rear-wheel drive, though speculation abounds. Who cares? The seats can be adjusted 30 ways! The Continental also showed off a bold chrome grille that will be the new face of Lincoln. The blue bomber also rolled on blinged-out 21-inch polished aluminum wheels, used a 3.0-liter EcoBoost engine and had huge LED head lights with "laser-assisted" high beams. All of this resulted in almost blinding attention. The concept drew rave reviews, stirred controversy with Bentley designers who argued Lincoln ripped them off, and most importantly, pointed a way forward for the newly determined brand that hopes to compete with Mercedes, BMW, Audi, Cadillac and Lexus.

With production starting late this year, Cadillac had more specifics at the ready. Engines? Cadillac has a couple V6s and a turbo four for sure. It's working on a hybrid, and has considered a V-Series variant. It's based on a new rear-wheel-drive, aluminum-intensive chassis called Omega, features an advanced collision-mitigation system with automatic braking and has a cabin that's laden with "leathers, exotic woods and carbon fiber." It will be assembled at GM's Detroit-Hamtramck factory and goes on sale next year. At this point, Cadillac is more than willing to talk about every except for the price. The devil was not in the details for Cadillac, as evidenced by the CT6. But it wasn't for Lincoln either.

Cadillac mulling CTS Coupe successor after all

The 2014 Cadillac CTS made a big splash last week at the New York Auto Show, but now that we've seen the sedan, we can start to wonder about whether coupe and wagon versions are in the cards. According to Edmunds, Cadillac is at least considering bringing back the CTS Coupe for a second generation, which seems like an even better chance since the brand's global marketing director, Jim Vurpillat, was quoted as saying that the car was the top-selling luxury coupe in the industry.
Of course, this goes against reports we heard last year that Caddy's coupe and wagon would live on just not under the CTS name, but the interview with Vurpillat has us hopeful for a next-generation CTS Coupe. If it does come to fruition, we would expect the new two-door to have a largely unique exterior design like the current CTS Coupe, to echo that of intended rivals like the Mercedes-Benz E-Class Coupe and even the high-dollar BMW 6 Series.
