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.

Petrolicious eats up Rita Hayworth's 1953 Cadillac Ghia

The automotive industry has seem some wonderful transoceanic collaborations between America and Italy, from the Ford-powered De Tomasos of the 1960s to the alliance between Fiat and Chrysler today. Of course it's also seen unfortunate experiments in between like the Chrysler TC by Maserati and the Pininfarina-bodied Cadillac Allante. But before any of those, there was a beautiful tradition of rebodying American steel at the hands of Italian carrozzerie. And this could easily be among the most gorgeous of them all. It's a Cadillac Series 62 from 1953 with bodywork by Ghia. It's one of only two made, and has a star-studded history. The car was purchased by Aly Khan, prince of the Nizari Ismaili muslims and Pakistan's ambassador to the United Nations, for his wife... who just so happened to be the inimitable Rita Hayworth. They split up, but she held on to the car. Today it's part of the permanent collection at the Petersen Automotive Museum in LA, so the videographical artisans at Petrolicious went by to check it out. You'll want to as well in the five-minute short above.

Cadillac considering more electric cars, Elmiraj business case gaining popularity

Cadillac's electrification isn't likely to stop at the $76,000 ELR coupe, according a report from TheDetroitBureau.com. Speaking to Cadillac's global sales boss, Bob Ferguson, a successful ELR will likely lead to a larger, even more upscale offering than the Volt-based two-door. "I could certainly see a larger vehicle, something even more luxurious," Ferguson said of a potential second, battery-powered Caddy.
That car would likely boast a more potent version of the Voltec powertrain that motivates the Volt and ELR. This next-generation system is still sometime off, though, and won't likely arrive until the second-generation Volt hits the market.
Besides hinting at future plug-in hybrids, Ferguson spoke to TDB about the improving business case for the Elmiraj Concept, shown at the Pebble Beach Concours in Monterey in August. "I'm very excited about the reception for the Elmiraj," Ferguson said. "I'd like to see it in showrooms as soon as possible," he added, before saying that a business case for the production version of the big coupe still needed to be presented to the brass. "It was made to be operationalized," Ferguson added, which is just what we want to hear when it comes to big, flashy concept cars.
