Acura introduces a sleeker self-driving test car

As we creep ever closer to an autonomous-car future, one thing is for certain, most of the driverless cars we see being tested look hideous thanks to all the sensors strapped to the roof. Today Acura introduced its second generation Automated Acura RLX Development Vehicle with updated sensors and a more pleasing aesthetic. Gone is the spinning LIDAR system replaced with a more compact and robust version of the light detection and ranging technology. It's also got updated RADAR, camera, GPS and higher performance GPUs and CPUs as well as what Acura is calling "more intelligent software algorithms to support more complex testing scenarios." Acura and its parent company Honda have been testing autonomous cars at its GoMentum Station in the Bay Area since last year with a specially outfitted RLX (shown in the video above with the spinning LIDAR system). This new car will replace that vehicle. This article by Roberto Baldwin originally ran on Engadget, the definitive guide to this connected life.

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.

2002 Acura NSX fondly remembered in MotorWeek's retro clip

After a long wait, the new Acura NSX is finally here, but so far the latest generation is proving polarizing among enthusiasts. Whether it's complaints about the styling, the nearly $200,000 price, or the switch to hybrid power, nearly everyone seems to have a critique about the new sports coupe. That said, nostalgia for the original NSX remains strong, and the latest MotorWeek Retro Review of the 2002 model reminds us how different the new NSX is from the original. The 2002 model year marked the NSX's transition from pop-up headlights to fixed units, and it also features less noticeable styling tweaks along the sides and at the rear. Behind the driver, there is a 3.2-liter V6 with 290 horsepower and 224 pound-feet of torque, and it routes through a six-speed manual to get the coupe to 60 miles per hour in five seconds. There was also an available automatic gearbox with a 3.0-liter V6 that made 252 hp and 210 lb-ft. MotorWeek's review lavishes praise on the way the NSX drives by calling it "almost unflappable" and saying "body roll was almost nonexistent." With traction control off, the coupe changes character by becoming more twitchy and requiring that drivers use a careful balance of throttle and steering. Sounds perfect. Easily the best part of the review is when MotorWeek claims that a second-generation NSX is on the way. Over a decade later, that vehicle is finally, almost, on sale. Will it live up to the red-hot NSX standard of yore? We're about to find out. If you need any more nostalgia, the show previously remembered the '91 NSX, too. Related Video:
