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.

First-edition Detroit muscle raises millions for charity at Barrett-Jackson

Amidst all the classic metal crossing the auction block each year in Scottsdale, AZ, Detroit automakers have a tradition of donating the first examples of their most enticing new muscle cars, with the proceeds of their sales going towards worthwhile charities. This year, Barrett-Jackson handled three noteworthy examples. The highest price among them was the first Ford Shelby GT350R Mustang with the VIN #001, which raised $1 million for the Juvenile Diabetes Research Foundation. General Motors donated the first new Chevy Corvette Z06 Convertible, the first retail example of the droptop supercar garnering $800,000 for the United Way. Along with the Z06, GM also donated the first new 2016 Cadillac CTS-V sedan, which brought in $170,000 for Detroit's College for Creative Studies. Although these were the headline Motown muscle machines furnished by the automakers themselves, they weren't the only vehicles auctioned off for worthy causes. A 1950 GM Futurliner bus donated by collector Ron Pratte led the charge when it brought in $4.65 million for the Armed Forces Foundation. Other lots included a custom Jeep Wrangler donated by SEMA ($85k), a new M5 donated by BMW ($800k), a '79 Oldsmobile Cutlass Hurst ($140k), '39 Cadillac LaSalle C-Hawk ($410k), Jeff Gordon's 1999 NASCAR-spec Chevy Monte Carlo ($500k) and a Victory Cross Country 8-Ball motorcycle ($180k). All told, the charity lots raised over $8.7 million for local and national charities.

Cadillac ATS Crimson Sport Edition is here for a limited run

The Cadillac ATS has been a well-received entry into the small sport sedan segment for General Motors' premium brand, but keeping the model fresh is an understandably high priority. A two-door coupe variant is on the way and should help keep interest up, but the line's volume leader is still expected to be the sedan. In order to keep awareness high and sales going, GM will need to lavish a little attention on its four-door, as well. That's where the Crimson Sport Edition comes in.
Crimson Red Metallic paint is the exterior highlight for this special-edition Cadillac, while the interior is complemented with a number of microsuede touchpoints, including the heated steering wheel and shifter. To this point, the car's rich burgundy finish has only been offered on CTS-V Coupe and Sport Wagon models, and brand spokesperson Donny Nordlicht tells Autoblog that this is the first time that the company has offered a microsuede wheel with heat. Four interior trims are also available, although all have been seen previously.
The Crimson Sport will be limited to production this spring, and the trimmings can be added to either the 2.0T Performance or the V6 Premium specifications. Both rear- and all-wheel drive will be available, as well. Prices start at $46,010 for the turbocharged model and $51,010 for the V6 including destination fees, which represents a premium of $2,990 for the extra equipment.
