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.

2015 Cadillac Escalade is exactly what you expect [w/video]

Leading up to the debut of the 2015 Cadillac Escalade, we were told that the new luxo-SUV would be "much less ostentatious" and that we could expect greater differentiation from its Chevy Tahoe/Suburban and GMC Yukon siblings. And while those things may be true to some extent, after digesting the full raft of Escalade information and photography, we can say that this new 2015 model is exactly what we were expecting all along.
No, there isn't a single part of the new Escalade package makes us go "wow" or "ooh," but it still looks like a solid, nicely updated offering that will surely attract the same sort of baller status when it hits the road. For starters, the new front end has been completely redesigned, where cleaner, tauter lines work with the full-LED headlamps and running lamps to create a face that, while familiar, falls right in line with the rest of Cadillac's lineup. Around the sides, the shape is exactly the same as the rest of the SUV's platform mates, with better-fitting body panels and a handsome, upright design. Of course, 20-inch wheels are standard, and hifalutin' 22-inch rollers are available (in chrome, we assume). Things get really interesting around back, where full-LED taillamps extend from the bumper all the way up to the top of the tailgate, and - like the Tahoe/Suburban/Yukon - the rear window wiper has been integrated into the top of the hatch for a cleaner look. It all looks pretty modern and good, but doesn't really tone down the otherwise flashiness of the Escalade package.
Like its predecessor, the new Escalade will be available in standard- and extended-wheelbase formats (bring on the EXT!). Only one engine is available: GM's 6.2-liter EcoTec3 V8, good for 420 horsepower and 460 pound-feet of torque, mated to a six-speed automatic transmission. Both two- and four-wheel drive configurations will be offered, and the new Escalade should be a bit better to drive than the previous model, with a new coil-over front suspension and five-link rear setup, a wider track, variable-assist electric power steering and Cadillac's Magnetic Ride Control system with Tour and Sport modes.

Chevy's low-cost pedestrian avoidance to debut on 2016 Malibu

The mainstreaming of safety technologies that began on luxury vehicles will get a big boost from General Motors later this year. The General says it plans to offer 22 driver assistance systems across its product portfolio of 2016 models, starting with the redesigned Chevrolet Malibu - the one that we know will keep tabs on teenagers for the benefit of parents. Pedestrian avoidance will be another of its available options. Instead of kitting the sedan out with numerous and expensive radar arrays, the GM system uses the camera mounted next to the rearview mirror that is already used for the lane-keeping function. New software lets it detect pedestrians, and when it detects a potential collision with one, it can alert the driver and brake autonomously if the driver doesn't react. Eventually, engineers want to give it the ability to do the same with cyclists. Because it uses existing hardware updated with new code, GM says the application costs "a few hundred dollars." GM demonstrated the Front Pedestrian Braking preventing a crash with a dummy pedestrian at speeds up to 15 miles per hour. Automotive News reports that it will reduce the severity of impact up to 40 miles per hour, but "may not be of much use in collisions at higher speeds." That feature will also join the options list of the Cadillac CT6. The press release below has more on GM's driver tech soon on the way.

Safety engineers will develop and test these and other safety technologies for products around the world at GM's new, 52-acre Active Safety Test Area at its Milford Proving Ground near Detroit. The $14 million facility officially opened Friday. "Our comprehensive safety strategy of helping customers before, during and after a crash continues," said Jeff Boyer, vice president of GM Global Vehicle Safety.
