J.D. Power: Vehicle dependability at all-time high, Lexus and Porsche lead

Each year, J.D. Power and Associates surveys original owners of three-year-old vehicles to find out what kinds of problems they have had experienced over the last 12 months, and then it uses this data to create its annual Vehicle Dependability Study. This means that the models in the 2013 study are 2010 model year vehicles, and J.D. Power rates each make as well as the top individual models based on how many problems were experienced per 100 vehicles (PP100).
Debunking the idea that carryover models are more dependable than new or updated models, the 2013 study found that the average carryover model experienced 133 PP100, while all-new or redesigned vehicles for the 2010 model year had 116 PP100; vehicles that received minor changes fared the best with just 111 PP100. The overall average for all makes was 126 PP100, which is the lowest figure since the findings were first issued in 1989.

Lexus LC Coupe and Convertible add a bevy of official TRD parts

TRD stands for Toyota Racing Development, but that doesn’t stop the performance division from developing parts for Lexus products, too. One of those Lexus products it just released a set of performance parts for is the LC 500. The two-door coupe is our favorite Lexus for sale right now because of its excellent driving dynamics and stunning looks, so adding more performance is a good thing, right? WeÂ’ll stop short of saying itÂ’s a great thing for appearances in this particular instance. The parts shown here tend to muss up and clutter the LC's otherwise gorgeous design. That large rear wing, aero cowling above the rear seats and aero mirror cover all notch the aggressiveness up a level, but it makes the styling look a bit messier in photos. TRD does claim real performance gains from the parts, though. The modified side skirts reduce the amount of wind flowing to the rear tires, which makes the car slipperier through the air — TRD also claims a benefit in fuel economy and reduced wind noise. There are three new wheel designs, all offering a reduction in weight over the stock wheels and an improvement in rigidity. The wheels pictured on the car are the Lunanium Gun Metallic option. TRD says the giant aero cowl reduces wind noise in the cabin for the LC Convertible, and the big rear wing improves vehicle stability. Other available parts include a front spoiler (adds downforce, lowers front clearance by 30 mm), rear diffuser (adds moderate downforce, says TRD), smaller rear spoiler (improves stability at speed), and a “performance damper.” Details are short on this damper, but we can assume itÂ’s slightly stiffer than stock and could offer a noticeable handling improvement. ThereÂ’s a 3-D mini configurator you can play around with on TRDÂ’s site, too. You can only choose between the exterior color, interior color and aero cowl cover, but itÂ’s worth it to see what the mods might look like on your particular LC. Interestingly, the aero cowl sitting above the rear seats can be had in either black or white. Availability of the parts in the U.S. is still unclear, but weÂ’re reaching out to TRD and will update with any news we might hear.  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."
