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.

Five awesome Lego car creations

Lego cars are among our favorite toys. They're fun for play, and if built properly, great to display. With that in mind, we've crafted a list of some of the best creations we've seen. Some are on sale now, while others are merely the work of fanciful enthusiasts. There are even a couple that you definitely cannot buy (we'll explain).
Our choices are diverse, including everything from a diminutive 1969 Chevy Corvette to a fullsize Ferrari Formula One racecar. These are just five projects that caught our eye - there are many more out there - so if you don't see your favorite Lego car on the list (or if you have your own creation), please tell us about it, in Comments.

2013 Cadillac ATS Premium 2.0T 6MT

The new Cadillac ATS is an impressive sport sedan, often considered one of the most serious threats to the BMW 3 Series. Unlike GM's previous attempts, this four door brings aggressive styling, commendable chassis dynamics and class-leading handling to the highly competitive battle. And, like its daunting German foe, Cadillac offer several powertrain choices.
I recently spent time with the ATS 2.0T Premium on my home California turf. Fitted with a turbocharged 2.0-liter four-cylinder engine mated to a six-speed manual gearbox with a limited-slip rear differential, my tester was lightly optioned, with only a paint upgrade and a cold weather package. That brought the as-tested price to $46,305, configured the way I imagine most enthusiasts would prefer. This meant I fully expected to enjoy a week with a tossable sport sedan that boasted "fun-to-drive" as its middle name, but all was not well...
