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."

Are you the Lexus GS F?

It's been a while since we've heard rumors of the fabled high-performance Lexus GS F, but thanks to our eager spy photographers, this looks to be our first real proof of the machine's existence. We don't have the usual brace of photos from all angles to work with this time around, our spies saying that every time Lexus' garage door opened, engineers jumped in front of the cameras to prevent the car from being photographed.
Even so, we have a pretty clear glimpse at some significant changes to this GS sedan, including the same staggered, quad-pipe exhaust found on the Lexus IS F. There's also an air diffuser panel nestled between the exhaust outlets, as well as a larger lip spoiler and unique wheels (matching those of the RC coupe) wrapped in high-performance tires.
Last time we heard rumors of the GS F's existence, sources predicted that the M5-fighting sedan would use a tuned version of Lexus' 5.0-liter V8, producing something like 465 horsepower. We have also heard that the automaker plans to reduce weight wherever possible, and that the final curb weight will be something like 3,700 pounds.

Lexus LF-LC approved for production

On the sidelines of a press drive for the 2014 Lexus IS, the company's vice president of marketing in the US told Ward's Auto that the honchos in Japan have approved the Lexus LF-LC concept for production. He wouldn't offer any other details on how the luxury coupe might be transformed into a vehicle for the buying masses, and that has led to a bag full of speculation.
The show car was hybrid-powered and rear-wheel drive, a beautifully executed stab by Toyota designers in Newport Beach at redefining Lexus, but even with the concept, the point was to keep it "within reach for premium buyers." The report says the odds are on limited production and higher pricing than Lexus' "mainstream products," and other sites have speculated on what kind of powertrain it might end up in showrooms with.
GT Channel posits that the LF-LC will be the inspiration for a coupe in the Lexus LS price bracket with a choice of either the 4.2-liter V8 or the hybrid powertrain from the LS 600h, further speculating it will be called LC 550 and cost more than $100,000. It then says that there would be another coupe created beneath that one to replace the SC 430. Lexus Enthusiast, however, calls those "warmed-over rumors" and says that the marque probably won't deviate from its engine-capacity-naming scheme - labeling a car with a 4.2-liter V8 an LC 550. Nor does it think Lexus will use the letters LC after the company has trademarked "RC" in the US and Australia.
