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 flagship spotted testing in the desert

Most of the Lexus line-up has been updated with the company's unique design language. Whether you love it or hate it, most of the company's cars are impossible to confuse for something else. But during this time of transformation, the flagship LS sedan has lingered with a very mild, sedate shape. These spy photos show the LS has gone under the knife. That being said, we can't really say how different the LS is going to look for sure because Lexus has employed some impressive camouflage. If we didn't know better we'd say it looks like the LS is going retro with round reflector headlights and some rear tailfins. But we do know better, so don't look for those features to make it to the production model. What we can make out is the lower half of the Lexus "spindle" grille. The camouflage wrapping is pressed up against a trapezoidal shape at the front reminiscent of what we've seen on other Lexus models. It looks like a large version of it as well. This Lexus seems to still be quite long, and based on where the rear passenger is in the photos, it still seems to have loads of space for rear passengers. It's difficult to tell if this is a long wheelbase model or a standard one, but if it is long wheelbase, it's proportioned quite nicely. It looks like there will be quite a large C-pillar on this LS too. Our spy photographer expects this car to be revealed next year as a 2018 model available with a V8 and possibly a hydrogen powertrain. So if you want one of the last low-key LS models, you'll want to get the current version because its days are numbered. Related Video:

Lexus RC F is a predatory sport coupe with a 450-horsepower beating heart

Take a look at that face. We can't be the only ones who see an automotive Predator staring back, right? Certainly, the Lexus RC F Coupe boasts a visually striking design that some are going to love and others are going to hate, but we can at least appreciate that it's aggressive, especially compared to the standard RC Coupe that we saw at the Tokyo Motor Show. And with good reason - there's a 5.0-liter V8 engine sitting under that massively domed hood with "more than 450 horsepower," along with a newly calibrated eight-speed automatic gearbox.
Interestingly, Lexus has tuned the RC F's engine to run on an Atkinson cycle under most circumstances, while it switches to the more typical Otto cycle when more power is required, presumably using some sort of advanced variable valve timing technology. Helping put that power to the ground with all those ponies wreaking havoc underhood is a torque vectoring differential, a first from Lexus.
Also involved in keeping the RC F planted is an aero package that includes wings and ducts galore. The headline bit is an active rear wing that deploys at 50 miles per hour and retracts back into the deck when the car drops back to 25 mph. A clear-coated carbon fiber roof can optionally join that carbon rear wing. There are apparently going to be three 19-inch wheel options, including the ones you see in our live image gallery above.
