Toyota develops new pre-collision system with steering assist

A number of automakers are working on developing fully autonomous cars, but it looks like the groundwork for such technologies will likely show up first as semi-autonomous systems for both safety and convenience. Following recent announcements from Nissan and Ford in this area, Toyota has now released information for some of its advanced semi-autonomous technologies that could be offered in production cars over the next few years.
On the safety front, Toyota's new pre-collision system with pedestrian-avoidance steering assist is aimed at protecting the folks who aren't in the car. This system combines visual and audible alerts with automatic brake assist and automatic steering. If warnings don't get the driver to slow down, the brake assist kicks in if a collision is very likely, but if that is still not able to avoid the impending collision (and if there is enough room to do so), the car can automatically steer itself around the pedestrian. This sounds most beneficial for last-second dangers such as a person accidently stepping out into the road in front of a car. Toyota hopes to have this technology available to customers by 2015.
The Japanese automaker is also testing a suite of technologies called Automated Highway Driving Assist (AHDA). The key part of this is a new adaptive cruise control system that uses vehicle-to-vehicle (V2V) communications rather than a radar-based system. This cooperative-adaptive cruise control allows vehicles to communicate their acceleration and deceleration data with other cars, which Toyota says this helps to improve fuel efficiency and traffic flow. Also a part of AHDA is the Lane Trace Control feature, which sounds like a next-gen lane keep assist. This system uses cameras, radar and a computer to keep the vehicle in a "smooth driving line" by being able to change steering angle, engine torque and braking force. Toyota says this technology could be in place by the "mid-2010s."

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.

2018 Lexus RX 450hL hybrid will start just over $50,000

Lexus has announced pricing on its 2018 RX 450hL, saying that its new three-row, all-wheel-drive hybrid crossover will carry a starting MSRP just $1,550 higher than the non-hybrid AWD RX 350L when it goes on sale starting in April. The RX 450hL will start at $51,615, positioning it right in-between luxury crossover competitors like the Mercedes-Benz GLE 350 and Infiniti QX60. The Luxury package, which adds features like semi-aniline trimmed seats, interior LED ambient lighting, laser-cut wood trim and 20-inch machine-finished alloy wheels, bumps the price up to $55,550. Prices include a $995 delivery, processing and handling fee. Lexus says the 450hL will get new features like second-row captain's chairs, leather-trimmed seats and complimentary Lexus Inform Safety Connect and Service Connect membership for the first 10 years of ownership. Standard safety features include a pre-collision system with pedestrian detection, lane-keep assistance, intelligent high beam headlights and all-speed dynamic radar cruise control. The RX 450hL combines a 3.5-liter V6 engine with two high-torque electric drive motor-generators to produce 308 in combined horsepower, with an EV mode allowing it to run on pure electric power at lower speeds for short periods. Lexus hasn't yet released fuel-economy figures for the hybrid, but the conventional RX 450h is rated at a combined 30 mpg by fueleconomy.gov. Lexus has added 4.3 inches to the rear body length of the 450hL and added more room for third-row occupants by incorporating a steeper tailgate. We've previously covered the introduction of the three-row RX 450hL and the 2018 RX 350L, which is powered by a 290-hp 3.5-liter V6 and is available in both front- and all-wheel-drive. The latter starts at $48,665 and goes up to $55,080. The RX line has been Lexus' best-selling model, with sales of 108,307 units in 2017.Related Video:
