Cadillac introducing V2V communications on 2017 CTS sedans

While Audi has introduced vehicle-to-infrastructure technology in select cars in select cities, Cadillac is focusing on vehicle-to-vehicle (V2V) communications, and it all starts with the CTS sedan. Starting this month, the company will be adding V2V equipment to 2017 models. The feature will be standard on cars in the US and Canada. These V2V devices will allow these new Cadillacs to communicate with each other up to 980 feet away. The cars will be able to transmit and receive information on speed, direction, and location. An example of how this data can be used is in detecting a car coming up a side street that could pose a possible collision risk. The cars will also be able to transmit data about brake use, hazard lights, and low traction situations for advance warning of hazards. The warnings can be displayed on the instrument panel and heads-up display. Currently, the system only communicates with other CTS sedans equipped with the technology. According to Chris Bonelli at Cadillac part of the reason is that the CTS will be the only car with the equipment on US roads at the moment, but it also isn't currently set to communicate with other cars if they were to be offered right away. However, he said that the company is absolutely willing to work with other companies to make the system compatible if or when other cars are offered with the technology. This V2V system also doesn't send data to any sort of network, instead only communicating with nearby cars. For the time being, this precludes the possibility of receiving road condition information from cars that are farther away. But as Cadillac points out, it should work under any conditions with no delay since it isn't dependent on information from a network. As far as security is concerned, Bonelli told us that the Cadillac system does have firewalls and other security measures to keep it protected from interference. He also said the cars don't store any data they receive. In addition, none of the data could be used to identify a particular person. The cars use a radio frequency set aside by the government for this use. The introduction of this technology also puts Cadillac well ahead of proposed legislation by the Department of Transportation. The organization wants this type of short-range V2V communications equipment to be a standard feature by 2023, believing the technology could prevent many injuries and deaths due to crashes.

The 2021 Cadillac Escalade's triple curved OLED screens are gorgeous

The centerpiece and crown jewel of the 2021 Cadillac Escalade is the triple OLED screen setup facing the passengers. It’s an imposing cowl with 38 inches of screen real estate in total, and itÂ’s a Cadillac Escalade-exclusive piece of technology. An interesting and unique feature like this has the potential to set Cadillac apart from the stiff competition in the luxury space.  Its appearance is just like that of the Cadillac Escala concept. We donÂ’t often get to see interior concepts carried into production, so thatÂ’s exciting on its own. The layout consists of a 16.9-inch touchscreen infotainment system, a 14.2-inch instrument cluster and a 7.2-inch touchscreen to the left of the cluster. All of the screens are curved and use OLED technology, which is commonly used on the screen of your Android phone, iPhone or TV. It allows for the deepest blacks, best contrast ratios and extremely vivid colors. In short, an OLED screen is going to look better than an LCD screen, and thatÂ’s why Cadillac is using it. We sat down with a few folks who could tell us more about it. Phil Kucera, Cadillac interior design manager, gave us some background on the decision to implement this tri-screen layout. “To be honest with you, it was a high-end leadership decision,” Kucera says. “There was a lot of, 'Hey maybe we donÂ’t put that on the base level. And why do you have to use OLED?' Because OLED is not the cheap way to go. So the fact that it stayed that size and remained OLED Â… I would bet that youÂ’re going to see other people doing something like this. There was a real push to try and get here first.” Sounds like the screen could have ultimately been a victim of cost-cutting measures. WeÂ’re glad it made it into production, because it looks promising. Sameer Gupta, GM's engineer manager responsible for infotainment, walked us through the new digital landscape. If you didnÂ’t like the old Cadillac software from before, youÂ’ll be happy to learn that this system is a completely new user interface, sharing nothing with any software before. Gupta told us that this is “a complete first-of use of this interface.” “When we started doing the system, we envisioned a system that had rich graphics, but was also simple and adaptive,” Gupta told us. After spending some time poking around in an Escalade, we can report that the new menus are full of rich graphics, pleasing animations and snappy transitions.

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.
