Lexus LS 500 Inspiration Series is a limited extra-luxe edition of the flagship sedan

Lexus is continuing its trend of making its “Inspiration Series” of cars, and the latest model to get the treatment is the LS 500. Just like all the others before it, this one is mainly an appearance package meant to set it apart from other LS 500s on the road.  The first unique touch is its Deep Garnet paint that isnÂ’t available on the normal LS 500. Then you get 20-inch black chrome wheels that go quite nicely with the paint color. Lexus didnÂ’t forget the Inspiration Series interior, either. Standard is the ultra-luxe Kiriko glass trim you can get as an option on the regular LS 500. It looked stunning on that car, and itÂ’s going to look great combined with the white leather seats on this one, too. Lexus is also giving the Inspiration Series blue LED dash lighting and “Lexus” puddle lamps below the doors. There are only going to be 300 LS 500 Inspiration Series cars sold in America, and theyÂ’re going to be available to buy this fall. Mechanically, itÂ’s exactly the same as a regular LS 500 with the 3.5-liter twin-turbo V6 making 416 horsepower and 442 pound-feet of torque. As for pricing on this limited-edition model, Lexus isnÂ’t saying quite yet. A regular LS 500 similarly equipped is around the $100,000 mark, so look out for something in that range when we do get a price. Related Video:

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."
