Lexus builds final LFA supercar

Lexus has officially built the very last LFA. The 500th Lexus supercar rolled from the company's Motomachi facility on December 14th wearing all of the goodies of the Nürburgring package and white paint. Toyota's Lexus division started production on the car exactly two years ago on December 15, 2010 and built just one unit per working day. A total of 170 workers were hand-picked to handle parts manufacturing, assembly and painting for the LFA project. While Lexus has made it clear it will produce no more LFA models, lessons gleaned from the vehicle's construction may translate into other future products.
Specifically, Toyota says it may employ its carbon fiber reinforced plastic experience moving forward. As you may recall, the LFA made extensive use of CFRP and carbon fiber, and Lexus even created a special rotary loom to stitch together the supercar's A-pillars. Take a look at the brief press release on the last LFA below.

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."

Hardcore Lexus RC F spied along with facelifted model

The Lexus LC F isn't the only high-performance Lexus spied testing. Another of our spy photographers caught a hardcore version of the RC F sports coupe out testing with its more mild-mannered sibling, the latter of which was trying to hide its mild facelift. Of the two cars, the RC F is the more interesting for a couple of reasons, and not just because it will be the faster of the two. First of all, it looks like this RC F will be significantly lighter than the current model. The weight savings will likely come mainly from new carbon fiber panels that include the bare carbon hood and roof panel. It's possible Lexus will have found some other areas to save weight, but these parts are all we can see at the moment. The other reason this RC F is grabbing our attention is the impossible-to-miss rear wing. Its tall supports, large size and bold end plates signal that this is more of a track car than just a fast road car. Whether it delivers track-car levels of downforce has yet to be seen. The fixed wing is also likely lighter than the power-retractable one on the regular RC F. Another performance upgrade we can see are the giant cross-drilled brakes. One of the big mysteries of this car is of course whether Lexus will have upgraded the powertrain to match the other upgrades. We're not getting our hopes up. Lexus only has two versions of the 5.0-liter V8 (that we know of): the RC F version that makes 467 horsepower, and the LC 500 version that makes 471 horsepower. We could see Lexus using the slightly hotter LC version, but likely nothing new. Part of what leads us to think that is the RC F GT Concept Lexus built for Pikes Peak a few years ago. That car got loads of light parts, a roll cage and a wide body kit, but it had just the same 467-horsepower V8 as any other RC F. View 15 Photos As for the other RC on display in these spy shots, it gives us a solid look at the coupe's upcoming midcycle refresh. Interestingly, it appears Lexus has abandoned the split lights that had the Nike "Swoosh" style running lights. Now everything is integrated into single units. The outboard grilles now have more prominent strakes in them, and there's now a small grille or air inlet at the base of the main grille. Around at the back, there are almost no changes that we can see through the camouflage. Only a possible extension of the diffuser between the rear reflectors is all that shows through.
