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.

Liberace's gilded Cadillac could be yours

With their chrome grilles and oversized wheels, it's hard not to notice a Cadillac these days. But this one is even more blingtastic on account of the 23.75-karat gold-leaf bodywork.
The 1931 Cadillac Golfer's Drop Head Coupé is said to have belonged to the inimitable performer Liberace, who didn't just have it covered in gold - he also had the exterior door handles plated in silver and the inside handles in 24-karat gold as well. It's also got a white leather interior and headlights that - well ahead of their time (if you'll pardon us, Mr. Tucker) - pivot with the steering wheel. All that bling is powered by a 5.7-liter V8 mated to a three-speed automatic transmission that pales in comparison to the seven, eight and even nine-speed gearboxes appearing on luxury sedans today.
The project was undertaken over the course of three years in the 1970s by one Jack Smith from Kansas. Smith (if that was his real name) sold it at auction in 1975, and it was most recently displayed for 12 years at a museum in Germany which claimed it was Liberace's own. The car is now going up for sale by Barons' at the Sandown Park horse racing track in Surrey, England, on September 17, when bidding starts at 85,000 pounds - equivalent to over $130,000 at today's rates.

Cadillac toned down ATS Coupe design due to customer feedback [w/poll]

Automakers always face a difficult decision when it comes to styling their cars. Design them too blandly and nobody will get excited about them. But style them too aggressively and they'll often end up turning off potential buyers.
Cadillac, for its part, is no stranger to aggressive design, but when it came to the new ATS Coupe, it elected to tone things down a bit. Speaking with The Detroit News in a wide-ranging interview, Cadillac design director Bob Boniface revealed that the original design for its compact coupe was edgier - closer to that of the CTS Coupe - with a wedgier profile, a more steeply raked beltline and a more severe grille. But potential customers surveyed in clinics apparently didn't like it. They found it looked heavy, inefficient and not fun to drive. So Boniface and his team literally went back to the drawing board and "took as much visual mass out of the car as [they] could." The resulting coupe, while handsome, looks far more similar to its four-door companion than did Cadillac's CTS.
