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."

Toyota's future fuel cell vehicle lineup revealed?

Being an Olympic sponsor from 2017 through 2024 puts Toyota in the international limelight, and the company is preparing a fleet of efficient, cutting-edge vehicles just in time for the Tokyo games in 2020. At least eight new models could be on the way, according to Automotive News citing Best Car from Japan. Three of those might make use of the hydrogen fuel-cell powertrain developed for the Mirai. While many of these fuel cells are going into Japan-only vehicles, one of them could come here. Reiterating earlier rumors, Automotive News reports a hydrogen-powered Lexus LS is set for 2018. It could be even lighter than the current hybrid model, too. A similar version of the Toyota Crown would launch there in 2019 and possibly an FCEV Estima minivan, too. Beyond fuel cells, Toyota also intends to put the JPN Taxi Concept from the 2013 Tokyo Motor Show into production in time for the games, according to Automotive News. For 2017, the brand's flagship Century is also expected to adopt a hybrid V8 to replace the current V12, as well. Plus, many of its Japanese-market vans are also due for updates. All of this is certainly a massive undertaking to be ready in time, but Tokyo want to use the games as a chance to show the city as an innovative, international destination. Automotive News predicts Toyota could supply thousands of vehicles to haul all of the athletes and dignitaries around. In addition, the Japanese government wants 6,000 fuel cell vehicles on the road and 35 refueling stations up an running for the games. 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.
