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 SRX production moving to TN, next-gen Equinox going to Mexico

It's a good week for the town of Spring Hill, TN, as General Motors has announced that its factory in the city of 31,000 will receive a $185 million contract to produce engines. On top of that, the next-generation Cadillac SRX crossover will be built at the factory (NA models are presently built in Ramos, Arizpe Mexico), which was once famous for being the home of GM's now-defunct Saturn brand.
The factory is one of GM's six facilities around the globe that will screw together the company's new line of three- and four-cylinder Ecotec engines. Spring Hill currently builds the 2.0-liter, turbocharged Ecotec, as well as the naturally aspirated 2.4 and 2.5-liter variants.
Spring Hill's vehicle assembly lines were idled in 2009, but were reactivated in 2011. The SRX is just one of the products meant to benefit from last year's $350-million investment, and should have a positive impact, creating or retaining around 1,800 positions at the factory.

Cadillac recalls ELR coupe over stability control problems

Cadillac is recalling about 656 2014 ELR models made between September 26, 2013 and February 14, 2014, because of a fault with the electronic stability control system. On cars without adaptive cruise control, it's possible that diagnostics could prevent the system from telling the driver if ESC is on or off.
Cadillac has a software fix ready and repairs begin on April 17. Alan Adler, General Motors' recall and legal spokesperson, tells Autoblog that only about 55 of the affected cars are in the hands of owners. The rest are either on dealer lots or still at the factory. There have been no reported injuries or crashes caused by the fault.
The correction for the stability control system involves a software recalibration of the electronic brake control module that takes around 20 minutes to perform. While they use the same platform, the Chevrolet Volt isn't involved in this recall because it "uses a different a brake control module," said Adler.
