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.

GM recalling Cadillac ATS, XTS, Chevy Impala over faulty brake lamps

General Motors has issued a recall covering 1,627 sedans over faulty brake lamps. Both the 2013 Cadillac ATS and XTS are affected by this problem, as is the 2014 Chevrolet Impala.
According to an official National Highway Traffic Safety Administration report, "the brake lamps may intermittently flash without the brakes being applied and the cruise control may disengage" on these vehicles. The report does not state that the brakes themselves are faulty, but rather that "if the brake lamps flash when the vehicle is not slowing, a following driver may not adjust vehicle speed when the vehicle is in fact braking."
This marks the first recall for the 2013 Cadillac ATS, as well as the recently introduced 2014 Chevy Impala. In late 2012, over 12,000 Cadillac XTS models were recalled due to a head restraint issue.

2019 Cadillac XT4 vs. other compact luxury crossovers: How they compare

After years of every other luxury car maker stocking their showrooms with trendy crossovers, Cadillac is finally joining the fray. Its latest addition is the 2019 Cadillac XT4, a tidy little crossover that proudly bears signature Caddy designs such as the tall slender taillights. And based on our first drive of the car, it impresses in many ways, such as its refined engine, classy interior and excellent ride quality. View 39 Photos That's good news for the little Cadillac, but it needs to stand out in a big segment. To see if it has any other areas where it shines, or maybe some where it's a bit dim, we decided to compare its specifications with those of four of the segment's bestselling compact crossovers, the Lexus NX 300, Acura RDX, Audi Q5 and BMW X3. And for good measure, we threw in the XT4's crosstown rival, the Lincoln MKC.

If you'd like to compare any of these vehicles with other luxury crossovers, be sure to check out Autoblog's Car Finder and Compare tools. Also, this is solely a comparison of basic specifications, and for more in-depth information on these cars, be sure to follow the links to our full reviews. And don't be afraid to check these cars out in person at their respective dealerships. Engines, transmissions and fuel economy With the exception of the Lincoln MKC's optional 2.3-liter engine, every competitor here resorts to the same type of engine, a turbocharged 2.0-liter four-cylinder, for its propulsion. And unsurprisingly, they make similar power, in the mid-200 horsepower and mid-200 lb-ft of torque range. Of the 2.0-liter engines, the standout is the Acura RDX, which produces a hearty 272 horsepower and 280 pound-feet of torque. It's second in power only to the Lincoln's optional turbo 2.3, which makes 285 horsepower and 305 pound-feet of torque. The bottom of the pack is the Lexus with 235 horsepower and 258 pound-feet of torque, but the next least powerful crossover is the Cadillac XT4, with just two more ponies than the Lexus, and the same amount of torque. View 22 Photos Though the Cadillac is nearly the least powerful, it does get to claim the best fuel economy numbers, rated at 24 mpg in the city, 30 on the highway, and 26 combined with front-wheel drive.
