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.

Ford C-Max Commercial Brings Cadillac 'Poolside' Ad Down To Earth

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.

Autoblog's ultimate holiday rides

Over the hills and through the woods, it's the time of year when many of us visit family and friends for the holidays. But getting there can be a chore. It's cold and snowy across much of the United States, and even if the climate is favorable, the drive to grandmother's house often is not. Think back to holiday road trips of yore: They probably included crying babies, antsy children, hungover adults and frequent bathrooms stops all around. Now, we're all at different life stages here at Autoblog, and the perfect car for one staffer might be as useful as a team of Budweiser Clydesdales to another. Some of us bounce from family event to family event with children and a labrador in tow, while others prefer a quieter, simpler holiday. But whatever the endeavor, we all need wheels. With that in mind, here is the unofficial Autoblog list of the ultimate cars in which to tackle the holiday season. 2015 Ferrari FF To borrow a chestnut from Top Gear presenter James May, "As you'd expect, I've done this properly." That oddly voluptuous ruby bolide in the photo above? It's a 2015 Ferrari FF – all 652 all-wheel-driven horsepower of it. What makes a Ferrari the ideal for holiday time in PaukertLand? My Midwestern winter breaks are wonderful, but they're typically frenetic and slushy, involving a lot of schlepping from house to house and even city to city, not to mention inevitable last-minute runs for forgotten presents and dinner ingredients. Needless to say, a powerful V12 is a welcome ally for such duties. And this one isn't just a friend when the road is clear. The FF has been gifted Ferrari's novel 4RM AWD system, and despite sitting lower to the ground than, say, an SUV, it's a pretty effective tool for real winter driving, especially when outfitted with a set of snow tires. Unlike other Ferraris, it's also a rather practical thing, with legitimate seating for four adults and 15.9 cubic feet of cargo space – that's precisely as much room as a Mercedes E-Class – and you can fold the rear chairs and cram 28.2 cubes-worth of holiday cheer in the back. Okay, so it's far from cheap and fuel economy isn't that great, but who cares? Just drop a paddle-shifted gear or two, bury the throttle and Repeat The Sounding Joy.
