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.

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.

Corvette's Performance Data Recorder headed to other cars, will Cadillac ATS-V be first?

For 2015, the Chevrolet Corvette Stingray gained a novel piece of high-performance technology: The Performance Data Recorder. This trick system combines video from a front-mounted camera with in-car data and GPS information to help drivers record and study their lap times, complete with data overlays. While it's a clever tool for track days, it's also finding popularity as a built-in dash cam of sorts. To this point, the technology has been a Corvette exclusive, but General Motors' executive vice president of global product development, Mark Reuss, has confirmed to Autoblog that it will soon be available in other vehicles.
At a media luncheon on Thursday, we asked whether GM was keen to expand usage of the technology to other models, and if we could expect to see something soon. Reuss coyly replied, "What's soon?" When we suggested the 2016 Cadillac ATS-V (which is scheduled to debut at next week's LA Auto Show), he replied, "There will be other uses, and it won't be that far away. How's that?"
Certainly not an outright confirmation, but we wouldn't be at all surprised to see the next high-po Cadillac roll under the klieg lights at the Los Angeles Convention Center next Wednesday brandishing more than just 450 horsepower.
