Cadillac's Super Cruise — look, Elon, no hands!

Cadillac is about to start selling vehicles with an autonomous driving mode and TechCrunch got an early look at the technology in a production car. "Wait for the green light and let go," the Cadillac engineer instructed. That's it. The car was driving itself. I, the person behind the steering wheel, was no longer the driver. Cadillac's Super Cruise system was driving. The 2018 Cadillac CT6 sped along U.S. 23 under the direction of Super Cruise. Traffic was light and the weather was perfect. The system held the Cadillac sedan in lane and responded appropriately to traffic. I spent an hour on the expressway and touched the steering wheel and pedals only a few times. Super Cruise made the drive boring. I think that's the point. Here's how it works Super Cruise is available once the driver navigates the vehicle onto an expressway. When ready, a little icon is displayed by the speedometer and the driver hits a button on the steering wheel to switch it on. Once the light bar on top of the steering wheel turns green, the driver can let go. Super Cruise is driving.This steering wheel light bar is key to the operation. When green, the driver knows Super Cruise is in control. Blue means the driver interrupted the system to change lanes and red means Super Cruise needs the driver to confirm they're paying attention and not checking Twitter. When active, Super Cruise controls the steering and speed, but again, only on an expressway. This is done through onboard sensors and using GPS and mapping data. GM employed GeoDigital, a startup in GM Venture's portfolio, to map 160,000 miles of expressways in the U.S. and Canada. The car company then used Super Cruise-equipped vehicles to test each mile. This combination of onboard systems combined with map data makes the system feel polished and sophisticated. During my admittedly limited time in the vehicle, the CT6 precisely held its position in the lane and confidently handled sweeping curves at speed. There was no wiggling or squirming — from the Cadillac or myself. The car was in control, and I felt safe. Although the driving conditions were perfect for my test ride, during adverse weather, the system will work normally until one of the key systems is unable to operate.

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 boss: We will have diesels

Johan de Nysschen doesn't usually mince words about his plans, and the Cadillac boss says that diesel-fueled models are on the horizon for the luxury brand in the US by the early 2020s. The four- and six-cylinder engines under development would launch first in Europe about 2019. "We will definitely bring them to the US," de Nysschen said during a press event, according to Automotive News. Unfortunately, the Cadillac president isn't saying which models would get the diesels, yet. This plan has been in the works for at least several months, and Cadillac made mention of the two oil-burners earlier this year during the unveiling of its new V6 engine. De Nysschen broached the possibility during an interview at the 2015 Detroit Auto Show, and he also referred to the inclusion of hybrids and plug-ins into the company's lineup at that time. Last year, a rumor suggested the addition of a V6 turbodiesel into the Escalade range. There were also rumblings of an oil-burning ATS during that model's launch. While Cadillac is no stranger to offering diesels in Europe, the decision to develop these new ones could come at an inopportune time. Governments there are rapidly moving against the fuel in favor of electrification. Tighter emissions regulations could also be on the way for the EU. Related Video:
