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.

Honda, Acura EVs will adopt Tesla's NACS charging port

CARMEL, Calif. — As more and more automakers pledge to install TeslaÂ’s North American Charging Standard (NACS) ports on their electric vehicles, Honda says that it, too, will hop on the bandwagon. Future EVs from Honda – as well as its luxury division, Acura – will have NACS charging setups, giving these cars access to TeslaÂ’s huge network of Supercharger stations. "It is quite important," American Honda Motor Co. President and CEO Noriya Kaihara said in an interview Friday. "We also have to push NACS, as well. It is clear." As for when this will happen, Honda is currently at the mercy of General Motors. The Japanese automakerÂ’s next two EVs – the Honda Prologue and Acura ZDX – use shared architecture with GM, leveraging The GeneralÂ’s excellent Ultium battery technology. The ZDX will launch first, and have the traditional CCS port that isnÂ’t compatible with TeslaÂ’s chargers, but it will switch to the NACS design in 2025 or 2026. "We clearly depend on GM," Shinji Aoyama, Executive Vice President of Honda Motor Co., said during Friday's interview. "Once they [switch to NACS], this will follow for ZDX, as well." Looking to the future, Honda is part of a joint venture with seven other global automakers that will see the installation of more than 30,000 EV fast-charging stations across the United States and Canada. The chargers are still in development, but Honda says the companies are all aligned on the core values that are needed to make this charging network successful.  "The software needs to be really reliable and really open infrastructure so it communicates with every OEM's software," Jay Joseph, American Honda's Vice President of Sustainability and Business Development, said in Friday's interview. "The hardware needs to be capable of the highest levels of charging. It needs to be secure, it needs to be reliable, it needs to be accessible." Joseph said the current public charging companies know and understand the shortcomings with their systems, and that TeslaÂ’s Superchargers set an example of how to do chargers right. "If you look at what's so great about the Tesla Supercharger network, it's the maintenance," Joseph said. "They stay on top of it, they've got someone onsite monitoring the equipment, they're monitoring it electronically and remotely, and they fix it – fast. That's probably the most important thing." All the more reason for Honda – and other automakers – to switch to the NACS charging setup as quickly as possible.

Comma.ai makes your car semi-autonomous for $999

At TechCrunch's Disrupt conference in San Francisco, Comma.ai founder George "Geohot" Hotz announced the launch of the Comma One semi-autonomous driving device. Hotz said at the conference that his company has worked on the Comma One for about a year, and it will be available at the end of the year for $999 and a $24 per month subscription fee. But aside from the reasonable price, which TechCrunch points out is possible thanks to off-the-shelf components, the appeal here is that it's an add-on to an existing car that can be installed at home by the car's owner. This gives people with normal cars the opportunity to have semi-autonomous features without having to buy an entire vehicle... that is, if you have a Honda or Acura with lane-keeping assist, since Comma One is currently only compatible with those vehicles. It remains to be seen if the company will add more vehicles to the list over time. The device is roughly the size of a large cell phone or aftermarket navigation system, and it has a screen on the front and a pair of cameras on the back. The computer combines information from the device's cameras and the car's radar sensors to understand what's happening and how to respond. Hotz explained at the conference that this system is similar in capability to the Tesla Autopilot system, and will be able to complete a drive, start to finish, without the driver having to touch anything. He did however emphasize that the driver must still pay attention in the event something goes wrong, comparing the experience to watching a young student driver. Hotz told TechCrunch that the device should start shipping at the end of the year. He also said that owners of compatible Honda products in the San Francisco area are eligible for beta testing, and can get involved by emailing him at george@comma.ai. So if you've been pining for a semi-autonomous vehicle of your own, but couldn't spring for a Tesla, you won't have to wait much longer. We should point out that we don't know yet how well the system works, though we hope to find out soon. Related Video:
