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.

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:
