2015 Lexus LS gets tighter turning radius, new infotainment

Go back a couple of decades and the thought of a Japanese automaker challenging the German limousines would have seemed laughable, but 25 years later the Lexus LS is a mainstay of the luxury sedan market. And it didn't get there by sitting on its laurels, so it should come as little surprise that Lexus is offering some small tweaks as it enters the 2015 model year.
This time around the upgrades are rather minor, consisting primarily of a new multimedia system. It's got an updated navigation system with 12.3-inch display, revised backup camera imagery with dynamic gridlines, and an enhanced Lexus Enform App Suite that can control the locks, ignition, climate control and more, remotely.
While they were at it, Toyota's engineers also reduced the turning circle by four inches (on cars fitted with 18-inch wheels), and enhanced the F Sport package as well. Otherwise, it's essentially the same LS we've always known.

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 sets the pace Down Under

A few months back we reported that Lexus was considering competing in V8 Supercars, Australia's premier touring-car series. And while it might not be ready to launch a campaign of its own, the Japanese luxury automaker has done the next-best thing. Starting this season, the Lexus RC F will serve as the series' official safety car. The eight-cylinder muscle coupe appears to be mechanically unmodified, as it is apparently suitable to the task right out of the showroom. It has, however, been enhanced with a special livery, emergency lighting and an interior likely to have been upgraded with bucket seats, racing harnesses, a roll cage and emergency equipment. The RC F safety car will be joined by an IS 350 F Sport that'll serve as the medical car and another GS 350 F Sport support vehicle, giving Lexus a strong presence on the circuit Down Under and potentially paving the way for a competitive assault on the series in the near future. Aussie racing fans can expect to see the trio on the track starting with the Clipsal 500 in Adelaide later this month. It won't be the first time we've seen Lexus provide a safety car in Australia, but it's a definite step up in profile from the GS 350 that has served for the past few years at the same Sydney Motorsport Park where this trio was launched. 06 February 2015 LEXUS ROARS INTO V8 SUPERCARS WITH RC F SAFETY CAR The Lexus high powered performance RC F coupe will feature as V8 Supercars' official Safety Car in 2015 as part of a new partnership between the Japanese luxury marque and V8 Supercars, Australia's premier motorsport series. A Lexus GS 350 F Sport and an IS 350 F Sport will also be on track as the championship's official course and medical cars as part of the new agreement. The RC F, which is equipped with a 5.0-litre V8 that produces 351kW of power and 530Nm of torque, will feature at each of the 15 V8 Supercars Championship events in 2015 alongside the GS 350 F Sport and IS 350 F Sport. Lexus Australia chief executive Sean Hanley said the partnership with V8 Supercars was a fitting match for the brand. "V8 Supercars is the world's leading touring car series and our involvement as supplier of vehicles reflects the new energy in our brand and our dynamic model lines," Mr Hanley said.
