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 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.

This is what a Lexus RC-based 'four-door coupe' might look like

It feels like there is a secret law in Germany mandating that every domestic automaker there must offer at least one model with a four-door coupe bodystyle like the BMW Gran Coupes, Mercedes-Benz CLS and Audi A7. Several of the German brands even have the swoopy sedans in multiple sizes. So far, Lexus has stayed out of that fray, but maybe not for long, if a recently spotted test car makes it to market.
The brand is known to be testing a highly styled four-door coupe, roughly the size of the GS, under heavy camouflage. Little is known about the new model at the moment, but its existence makes sense. If it really wants to take the on Germans, Lexus is going to have to fight them toe-to-toe with competing models - especially with ones understood to have high margins.
Pictured above is a rendering from artist Theophilus Chin imagining a slightly smaller take on the genre based on the RC coupe, which he calls the RC GT. His design leaves the original shape almost untouched, but shortens the front doors to allow room for a rear doors under the arching roof. His GT would be aimed more against the BMW 4 Series Gran Coupe and rumored Mercedes-Benz C-Class four-door coupe, rather than the larger models Lexus actually appears to be targeting with its vehicle under development. His concept certainly nails the look, though, and while it might not have a basis in reality, we thought that it's well-resolved enough that you'd want to take a look, if only as a "what could've been" flight of fancy.
