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.

2014 Cadillac ELR whirs into Jay Leno's Garage

While Jerry Seinfeld was gallivanting around LA with Sarah Silverman in a Jaguar XKE, our favorite car-loving comedian, Jay Leno, was checking out the all-new 2014 Cadillac ELR. Set to go on sale later this year, Cadillac brought its ELR to Jay Leno's Garage to show off some of its styling and technology as well as give Leno some seat time in the range-extended EV. Leno owns both a Volt and a CTS-V, and the ELR is a kind combination of the two (sort of).
In this episode, Leno spends some time talking to Frank Saucedo, GM director of advanced design, and ELR chief engineer Chris Thomason before logging a few miles on the sleek coupe. Interestingly, it seems that GM has definitely changed its tune a little since the introduction of the Volt a couple years ago; Saucedo and Leno both refer to the ELR as a hybrid, and Thomason says that it gets the "bulk of its propulsion" from the electric motors. Whatever you want to call it, scroll down to watch the latest episode of JLG with some great information and driving shots of the plug-in Cadillac.

Is this the 2014-15 Cadillac Escalade?

Following the introduction of the redesigned Chevrolet Silverado and GMC Sierra, we're expecting General Motors won't wait too much longer to show off the next-generation fullsize SUVs that share this platform - including the Cadillac Escalade. It's still not clear if the next Escalade will debut for the 2014 or 2015 model years, but Carscoops has what it claims to an exclusive first look of the new Cadillac, revealing a portion of the headlight, front fascia and wheel.
Judging from this small picture, it looks like the Escalade could incorporate styling cues that we've seen on new Cadillac models like the ELR and the 2014 CTS, but that article says that other design details could include tall, vertical taillights similar to the CTS Wagon, staggered-width wheels and a narrower daylight opening for the side windows. The last time we saw the fourth-generation 'Slade back in October in spy shots, the heavy camouflage prevented us from getting an idea of the luxury SUV's appearance, but this image and description gives us something to look forward to. Head on over to Carscoops for more potential information as well as a full rendering from back in January.
