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."

Lexus LX J201 concept is part SUV, part 550-horsepower rally car

Lexus transformed the LX, its biggest SUV, into a supercharged off-roader that sends chills down the Ford F-150 Raptor's spine. Although it's only a concept, it will attempt to tame the desert during the 2020 Rebelle Rally. Based on the venerable Toyota Land Cruiser, the LX is a formidable off-roader even without any modifications. Many examples nonetheless end up decked out with aftermarket parts, and it's these go-anywhere rigs that inspired Lexus to create the J201. Its name comes from URJ201, which is the current LX's internal designation. Stylists started by chipping several slats off the SUV's sizeable spindle-shaped grille to accommodate a winch and a light bar that's safely tucked behind a protective cover. Other aftermarket parts installed on the J201 include a snorkel, a roof rack, running boards, and a metal rear bumper with a pair of swing-out racks that carry extra fuel and a spare tire. Users can access cargo stored on the roof via a ladder installed out back. When the going gets tough, off-roaders can count on skid plates, a lifted suspension, 17-inch wheels, and 33-inch General Grabber X3 tires to help them soldier on. There's also an onboard air compressor, which lets drivers fill up the tires (after crossing sand dunes, for example) even if they're nowhere near a power outlet.  Lexus pegs the J201's output at 550 horsepower and 550 pound-feet of torque thanks in part to a Magnusson supercharger, but it stopped short of revealing technical specifications. It might have added forced induction to the stock LX 570's 5.7-liter V8, which effortlessly delivers 383 horsepower and 403 pound-feet of torque in its standard configuration, or it might have replaced the eight-cylinder with another engine from its arsenal. Regardless, an automatic transmission channels the cavalry to the four wheels via upgraded differentials. It doesn't sound like the J201 will ever see the light that awaits at the end of a production line. It's based on a model that sells in extremely limited numbers (4,718 units found a home in 2019), and that's nearing the end of its lifecycle. This concept is not destined to spend the next few decades in a warehouse, however. Rachelle Croft and Taylor Pawley will enter the J201 in the 2020 edition of the Rebelle Rally, which starts this Thursday, October 8. Open exclusively to women, the event will take competitors through 2,000 miles of grueling terrain in California and Nevada. Related Video:

Lexus to display turbocharged LF-NX Concept at Tokyo Motor Show

Concept cars typically have a short lifespan. They debut at a major international auto show, then make the rounds of the lesser local shows, and that's pretty much it. They might be loaned out for test drives or put on display in a museum, but by and large they've had their fifteen minutes of fame by that point. That said, Japan's automakers have found a way to keep these show cars going and keep them in the news. They're modifying them and giving them a fresh lease on life.
That's what Subaru is doing with the Viziv concept for the upcoming Tokyo Motor Show, and what Lexus is doing as well with the LF-NX concept. Having already unveiled the crossover concept at the Frankfurt Motor Show, Lexus is fitting the LF-NX with a new 2.0-liter turbo engine. (But then, as far as we could tell, Lexus never revealed engine specs for the concept in the first place.)
To go with the turbo engine, Lexus has also fitted the concept with a new front splitter, but otherwise it's the same - and even appears to be wearing the same liquid-metal paint, unlike the LF-LC concept that got repainted from red to blue when its limelight was starting to fade.
