Lexus LC 500 coming to Detroit Auto Show

Believe it or not, it's been nearly four years since we first saw the Lexus LF-LC Concept. Its swoopy style and spindle grille kicked off a big design revolution for Lexus, and we saw a number of LF-LC design elements work their way onto production cars. But now, rumor has it a full-on production version will see the light of day, and soon. Motoring.com.au says the LC 500 coupe will show its face at the 2016 Detroit Auto Show in January, and we have little reason to doubt this. In fact, it's kind of been a long time coming. The LC was reportedly approved for production in 2013, and though we were told it might resurrect the SC name, Lexus filed copyright applications for "LC 500" and "LC 500h." Oh, and a prototype of this car was recently spotted testing. The LC 500 will arrive with – no surprise here – Lexus' naturally aspirated 5.0-liter V8, plucked from the RC F and GS F. That said, Motoring says it could arrive with a new, 10-speed automatic transmission from Aisin. As for the LC 500h, Motoring thinks it'll be powered by a, 3.5-liter V6-based hybrid drive system that could produce something like 470 horsepower – not the current V6/hybrid unit from the GS 450h. A hotter LC F should follow in a couple of years, and earlier reports suggest it could make something like 600 horsepower. Of course, Lexus refuses to comment on future product speculation, so we don't have any official proof that this is actually happening. But it all makes a lot of sense. Watch this space in two months' time for more details.

Toyota reveals latest autonomous tech test bed

Toyota revealed its latest autonomous technology effort Friday, a sophisticated Lexus LS 600hL prototype that showcases its plans to advance in the emerging field. The Lexus is the first developed entirely by the company's in-house Toyota Research Institute and it will focus on the car's ability to learn and see behavior on the road. Toyota is showing the car at the Prius Challenge event at Sonoma Raceway. The Lexus uses Lidar, radar, and sensors, which potentially reduce reliance on mapping. The prototype advances Toyota's last concept vehicle shown at the Consumer Electronics Show in 2013. This one is said to be more flexible and it will focus on Toyota's two autonomous tech pillars, called Guardian and Chauffeur. Guardian is meant to improve safety features, while Chauffeur moves toward full autonomy. "We believe Guardian can probably be deployed sooner and more widely than Chauffeur, providing high-level driver-assist features capable of helping mitigate collisions and save lives, sooner rather than later," Toyota Research Institute Gill Pratt said in a statement.

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.
