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.

Cadillac imagines the future of luxury transportation with a drone and a pod

Besides more screens and electric cars, GM and Cadillac made sure to pay tribute to the other darlings of the tech industry: autonomous cars and drones. Both concepts take familiar ideas but add a touch of Cadillac flavor. And don't expect either of them to show up in reality anytime soon. The most fanciful of the two is the Cadillac VTOL concept, which stands for vertical takeoff and landing. It's a fully autonomous drone meant for shuttling people, likely wealthy executives, from rooftop to rooftop in busy cities. It's a single-occupant aircraft with a 90-kWh battery pack and is fully autonomous. It has four sets of two rotors that propel the drone to a top speed of 56 mph. The exterior is unique in having the front and rear sets of rotors at different heights, whereas most seem to have the cabin hanging from the rotors. You can spot some Cadillac cues in the beveled, angled edges. The other concept is the Personal Autonomous Vehicle or PAV. It's a fairly generic-looking autonomous pod with a pastiche of Cadillac design cues such as slim lights and angular trimmings. Cadillac says it's meant to be a social space, hence the wraparound bench seats in the cabin. Cadillac doesn't seem to have forgotten personal comfort, though, as you can spot a single-person recliner. Comfort is key, and Cadillac says the PAV would have biometric sensors to read the passengers and adjust the climate control, humidity, lighting and scents to make the the environment as pleasant as possible. Passengers will have control of vehicle functions via voice and gestures. At the end of theses vehicles' reveals, Cadillac teased more far-flung concepts coming soon. One of them will be a two-seat vehicle and mentioned that it would be for "you and someone very special" for more "intimate" trips. Related Video:
