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."

2014 Lexus GS gets eight-speed auto, other enhancements

The Lexus GS was totally redesigned for the 2013 model year, but Lexus is already tweaking its midsize luxury sedan. While a handful of small changes are being made, the big news for the 2014 model year is that rear-wheel-drive GS350 models will be getting a new eight-speed automatic transmission for improved fuel economy and performance.
Official EPA estimates have yet to be released, but Lexus expects this new transmission to return 19 miles per gallon in the city and 29 mpg on the highway - an improvement of 1 mpg highway. The GS450h still uses a continuously variable transmission, but Lexus says that it has been optimized to mimic the shift points of an eight-speed automatic. The final powertrain change made to the 2014 Lexus GS include tweaks to the GS350's engine intake and exhaust systems, which should help give the sedan a sportier feel.
Inside, Lexus has added Siri Eyes Free inside both the GS350 and GS450h, which allows drivers to use their iPhone's Siri voice assistant simply by pushing a button on the steering wheel. Other changes include a new full-color head-up display, and an available power trunk opener. A new Luxury Package adds LED fog lights, 18-inch "superchrome" wheels on the GS350 and 18-inch graphite-finish wheels on the GS450h. Interesting, the optional Lexus Night View system has been dropped.

Lexus IS, new and old, and LFA to make splash at SEMA

Lexus has announced its Specialty Equipment Market Association (SEMA) show cars: a group of eight Lexus IS sedans spanning all three generations, and a 2012 LFA supercar. One of the show cars, a custom 2014 Lexus IS 350 F Sport, is a creation penned by IS fan Rob Evans, the winner of a contest to design a Lexus SEMA show car.
The standouts in the group of Lexus IS show cars, in no particular order, are a 700-horsepower 2014 Lexus IS 340 (it has a heavily modified Toyota Supra inline six swapped in, which is stroked out to 3.4 liters, hence the nomenclature change) by Philip Case and a supercharged 2004 Lexus IS 300 by Maricar Cortez. Both cars prove that oldies can be goodies - the venerable Supra 2JZTE engine, which ceased production over a decade ago, lives on in a 2014 platform, and the 2004 IS 300 gets a supercharger and remains relevant through the use of electronics, such as a back-up radar sensor, upgraded headlights and more.
Of course, the LFA by Guy S. De Alwis will be a stand out on its own, but unfortunately Lexus only provided us with a couple pictures that don't do it justice. We'll have to take a closer look at it on the show floor. Same goes for the IS penned by contest-winner Rob Evans, of which only a rendering was provided.
