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 can't keep up with Escalade demand, can't move its sedans

No matter how much Cadillac revitalizes its lineup and its image, it seems that all consumers want is the Escalade. In fact, Automotive News reports that General Motors can't keep up with demand for the fullsize luxury SUV, despite sticker prices that start at over $70,000 and approach six figures at the top end of the spectrum. Contrast that with sedans like the ATS and CTS, which are far cheaper but which Cadillac hasn't been able to move fast enough to keep up with production, prompting both the manufacturer and dealers to offer substantial incentives to keep them from piling up. Cadillac had been resisting a price cut of the ATS or CTS, lest it hurt resale values – itself a factor that could explain consumers' reluctance to buy them in the first place – but been offering subsidized leases, discounted financing, rebates and cheaper options. Combined with incentives from individual dealers, according to AN, buyers can be looking at five-figure discounts on buying a new Cadillac sedan. And now, finally, it seems the CTS will indeed get a little bit off its bottom line. Yet GM has been producing the ATS and CTS at rates that their sales can't keep up with. The automaker was forced to idle the plant in Lansing, MI, where it assembles the ATS and CTS for six weeks starting this past December. And since it reopened late in January, it's been reduced to a single shift as dealers try to move the metal they've already got. Meanwhile the plant in Arlington, TX, that produces the Escalade and its Chevy and GMC siblings has been running on overtime, with three shifts throughout the week and even into the weekend to keep up with demand. Profitable as it's been for Cadillac and GM, though, the Escalade does not represent the future of where it wants to take the brand - separating the Escalade as almost a brand unto itself that's been left out of the company's new naming scheme. If only it could make its sedans as successful as its fullsize SUVs, it'll be all set.

Cadillac executive appointments have global flair

Cadillac has rearranged its executive suite in order to take full advantage of its sales momentum. Don Butler is moving from his role as US VP of marketing to a newly created position with the title VP of global Cadillac strategic development. It will be his job to "drive the next phase of Cadillac growth internationally," planning strategy and developing new markets.
He will be replaced by Steve Majoros, an exec poached from Chevrolet's ad agency of record, Campbell Ewald. Majoros, who has the Chevrolet campaigns "Like a Rock" and "American Revolution" on his resume, will oversee Cadillac's US and international marketing.
Another component in the brand's renewed global focus includes conducting an ad agency review. Announced last month, Fallon Worldwide remains Cadillac's agency of record, but others, said to include Campbell Ewald, will be bidding to make the creative that helps Cadillac expand sales percentages by triple digits here and in China.
