2014 Cadillac ELR is making green sexy in Detroit

In terms of styling, inside and out, the ELR hits the ball out of the park.
Cadillac has pulled the wraps off of its newest family member, the long-rumored, Voltec-powered, eye-catching extended range hybrid coupe called the ELR. The car makes use of the same basic architecture as the Chevrolet Volt, but has been thoroughly layered on with design, technology and performance tuning - with the goal of being a properly situated product for the Cadillac brand.

Cadillac developing stretched ATS-L just for China

To luxury automakers, long-wheelbase sedans are to China that crossovers and SUVs are to the US, so it isn't all that surprising any more when the latest sedan gets an extra couple of inches between the wheels to improve rear-seat comfort. According to Car News China, the next sedan to get the stretch will be the Cadillac ATS, which will increase the wheelbase by 10 centimeters (about four inches) to become the ATS-L.
Designed to go up against rivals like the BMW 335Li and the added-length Mercedes C-Class, the ATS-L will reportedly be built locally in China with an engine list that will grow as well. Currently, only the 2.0-liter turbo engine is offered in the ATS in China, but the ATS-L will get the full spectrum of ATS engines including the base 2.5-liter and the peppier 3.6-liter V6. This isn't the first time Cadillac has offered a China-specific stretched sedan either as the SLS dates back to 2006.

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.
