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.

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 Bladescan is another new headlight safety breakthrough U.S. won't get

Lexus is back at it with innovative lighting technology. The BladeScan headlights available in Europe on the 2020 RX utilize a new mechanism for throwing light further down the road, aiming that light more precisely, and doing so without blinding other road users. Lights from other OEMs with the same capabilities have increased the number of LEDs inside the housing for finer control. The BladeScan module inside the Lexus lights holds the number of LEDs down to 10 on each side of the RX, which Lexus says is a more cost-effective solution. In fact, BladeScan uses fewer LEDs than Lexus' most recent adaptive high-beam system, which has 24 LEDs on each side. The LEDs in the new module are arranged in two rows, eight on top, two on bottom. The diodes are fed information about objects ahead, and adjust their intensity to dim light aimed at an oncoming car, or illuminate a pedestrian by the roadside. However, the LEDs don't shine their light down the road, they shine their strobing light onto two blade-shaped mirrors — hence the name BladeScan — that rotate at high speed. The light reflects off the mirrored blades and into a lens, which orients the beam down the road. Not only is the reflected light easier to handle for oncoming drivers, the system has aim accurate to 0.7 degrees. Lexus' current adaptives are accurate to 1.7 degrees, making BladeScan a 143-percent improvement. That means the new feature can throw even more light into areas that are hard to reach with current lights — Lexus says pedestrian recognition at night has increased from 105 feet to 184 feet. Buyers of the 2020 RX will be able to take advantage when the new crossover goes on sale in Europe later this year. Naturally, U.S. Federal Motor Vehicle Safety Standard No. 108 means we won't get BladeScan — that goes for you, too, Canada. The now-52-year-old U.S. law mandates a single low beam and a single high beam setting, with no intermediate settings and no activation of high and low beams simultaneously. Toyota, Audi and BMW have been trying for six years to get FMVSS 108 changed to permit new and potentially lifesaving headlight technologies. The automaker wrote in a statement to Carscoops, "Last December, Lexus submitted a petition to NHTSA to allow ADB in the United States. Currently, we await the Agency's decision and hope to see an amendment in FMVSS 108."
