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.

GM recalls 83,572 SUVs for ignition switch issue

General Motors is recalling 83,572 SUVs from the 2011 and 2012 model years over a potential ignition lock actuator issue. In affected vehicles, the actuator isn't the right size, which could cause the ignition to get stuck in the "Start" position, and then either due to a jarring event or a "cool interior temperature" the ignition could switch back to the "Accessory" position. Doing so would cause a loss of power assistance and the airbags might not deploy. This is a different ignition issue than the one that's been ongoing for the past year. GM said it expects that less than 500 vehicles suffer from the problem, but that the pool could include vehicles from 2007 through to 2014 that have already been fixed, but with defective parts. The 2011-2012 SUVs included in the National Highway Traffic Safety Administration notice: Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles. GM will notify owners and dealers will inspect the ignition lock housing to see if it needs a free replacement. RECALL Subject : Ignition Lock Actuator may Bind Report Receipt Date: DEC 30, 2014 NHTSA Campaign Number: 14V827000 Component(s): ELECTRICAL SYSTEM Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2011-2012 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles. In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position. CONSEQUENCE: If stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags may not deploy, increasing the risk of occupant injury. REMEDY: GM will notify owners, and dealers will inspect and replace the ignition lock housing, as necessary, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact GM customer service at 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14696 for the original equipment, and 14912 for the service replacement parts.

Ford C-Max spot aimed squarely at Cadillac ELR 'Poolside' hubris [UPDATE]

If we had tried to predict the first video response to the controversial Poolside video for the Cadillac ELR, we would not have thought it would center on compost. But, hey, it's always nice to be reminded that the real world is sometimes better than fiction. Instead of the chic swagger of 'Poolside,' 'Anything Is Possible' is all about getting dirty. The new short in question is called Upside: Anything Is Possible and it promotes two things: Detroit Dirt and the Ford C-Max Energi. As in the ELR ad, Ford's plug-in C-Max only makes an appearance at the tail end of the spot, but instead of the chic swagger of Poolside, Anything Is Possible is all about getting dirty. The ad stars Pashon Murray, co-founder of Detroit Dirt, which takes natural waste from around Detroit, composts it into soil and then spreads that around "forgotten parcels" of Detroit to create urban farms. Detroit Dirt gets its bio-waste from a lot of sources, including the Detroit Zoological Society (all that herbivore manure has to go somewhere), Ford and General Motors, but this particular ad was the idea of Ford's PR agency, Team Detroit. It was a frenetic shoot, filmed with an LA-based director right after a big winter storm blew through Detroit, and Murray couldn't be happier with the result. "This was Ford Motor Company pushing my story, letting me tell the story that I believe in," Murray tells AutoblogGreen. "I get to help push this car and I get to tell my story." She says that the Team Detroit and Ford had to agree on the message, "from my understanding, [YouTube] is where they wanted to start, not where they wanted to finish." The ad is already getting a positive response on Twitter, so we won't be surprised if it shows up in more places soon. "It's not saying Ford is better than GM. It's telling the story of a black woman who's working hard in Detroit." As Detroit Dirt has off-screen support from both GM and Ford, it's unsurprising to hear Murray say that the video "is not a rivalry thing." She notes that the ad agency Team Detroit came to her and offered to tell the Detroit Dirt story using the framework of the GM ad. "It's a parody on this commercial, but it's not saying Ford is better than GM," she said. "It's telling the story of a black woman who's working hard in Detroit." What is that story? It's about urban farming, recovery and recycling. Murray tells us that for the last seven or eight years, she's been dedicated to sustainability.
