Weekly Recap: Automakers rethink the definition of luxury

Variety is the spice of life, but it's becoming a prerequisite for luxury carmakers in the ultra-competitive US market. The Detroit Auto Show was strong evidence of this reality. It's not enough to offer attractive and well-appointed cars and SUVs anymore. Luxury brands that want to be competitive need to invest in everything from high-powered supercars to clever hybrids. To be relevant, you need to be green and mean – and everything in between. As General Motors product chief Mark Reuss said after the reveal of the 640-horsepower Cadillac CTS-V: "We are not leaving anything on the table." He was speaking for Cadillac, but he might as well have been speaking for the luxury car market. The CTS-V debuted in Detroit about an hour after Lexus surprised showgoers with the reveal of the RC F GT3 race car and then announced ambitious plans to return to competitive racing. That almost overshadowed the fact Lexus had just revealed another potent addition to its growing F line, the 467-hp GS F.

Strong competition from all corners has forced automakers to refine and expand their lineups in ways unforeseen even a few years ago. Case in point: Mercedes-Benz finally has an answer to the BMW X6, rolling out the GLE coupe in Detroit. The X6, which blends coupe-like styling cues with some of the functionality of an SUV, debuted in 2008. Back then it was a punchline, but seven years and more than 260,000 sales later, the X6's success has compelled Benz to respond. Mercedes – one of the strongest proponents of diesel technology – also debuted the C350 plug-in hybrid sedan, which promises a range of 20 miles on electricity, though fuel economy figures were not announced. The car pairs Mercedes' well-received 208-hp turbocharged four-cylinder with an electric motor for total output of 275 hp and 443 pound-feet of torque. Meanwhile, Infiniti will add the Q30 hatchback to its lineup by the end of the year, new president Roland Kruger reiterated in Detroit. It's expected to be joined by a crossover variant, and the additions will help strengthen Infiniti in the United States and abroad. "While we're expanding our product line, we're also expanding our market reach," he said. That's something echoed by Jaguar executives, who are preparing to launch the brand's first crossover, the F-Pace, in 2016.

Mystery Cadillac coupe concept revealed in patent drawings

We have been reminded once again that when Cadillac designs a coupe, it's usually spectacular. The reminder comes in the form of a patent drawing filing that was previously reported on by Jalopnik. In the filing are shots of the two-door from just about every angle, and there's not a bad one in the bunch. Unfortunately, there isn't really any other information about the car in the patent, so the car remains a mystery in that regard. Still, there's a fair amount to be gleaned from the images. It certainly looks sportier than most recent Cadillac concepts. It has a fastback roof and a short deck lid. The rear bumper has a diffuser design fitted to it. The rear fenders are very wide. It has large auxiliary grilles on each side of the center one, and the way the taillights are designed seem to hint at extractor vents. The overall proportions even look a bit like those of the Camaro, but possibly a little larger. The car also looks like it's probably a concept. The side mirror stalks are far too skinny to actually be production units. The big diffuser and center exhaust, plus those rear extractor vent designs seem a little much for a production model, too. The headlights are also a little on the small side. Being a concept (probably), we're a little worried. We really want to see this thing come to market, but Cadillac has a bad track record of showing beautiful concepts that never make it to production, even when they aren't particularly over-the-top. The Elmiraj and Ciel are two that come to mind. The former was a coupe, too, and was elegant and grounded. We never got a production version of either. We did see some styling inspiration from the Elmiraj on the ATS and CTS, but they never quite captured the concept's beauty. Then again, when Cadillac has managed to bring a recent concept to production, the results haven't great. The Converj concept became the ELR, and while the styling came through fine, it was hampered by an uninspiring powertrain and an excruciating price tag. But hey, Cadillac could always prove us wrong. And we would like them to.

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.
