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 LF-Z Electrified previews future Lexus hybrids and EVs

While the company has yet to release a fully electric car or even plug-in hybrid in the U.S., the company is adamant that it's ramping up electric plans. One way it's doing this is with concept cars, and the latest is the Lexus LF-Z Electrified, just in case you forgot what powers it before the middle of this sentence. It's not a specific preview of any particular model, but is meant as a hint of a series of, well, electrified Lexus models coming in the next few years. The LF-Z is a clear evolution of the LF-30 Electrified concept from the 2019 Tokyo Motor Show. Like that concept, the front of the car effectively inverts the current Lexus grille design, with the "spindle" section in the middle being solid, and the area on either side covered with dark translucent panels that evoke open areas. The whole body is more crisp and creased than the LF-30, and it looks a little more grounded in reality. It has four conventional doors with actual door handles, the proportions are closer to a sedan or fastback, and a seemingly conventional taillight bar. But getting up close reveals many intricate details such as the cubic shapes in the front fascia, the frilled edges of the front fender flares, and the narrow breaks in the lighting. The interior is ultra-minimalist, with all the display systems placed around the driver, and a simple dash that wraps around to the doors and the rear seats. The seats themselves have a similarly geometric design to the exterior, and the choice to highlight the driver seat in a contrasting upholstery is interesting. Likely because the LF-Z doesn't preview any specific upcoming model, Lexus offered nearly no details about what powers the concept beyond electricity. It has the batteries mounted in the floor, and it features dual motors, one for the front wheels and one for the rear wheels, which isn't particularly remarkable. No range or power numbers were given. Steering is done by-wire, kind of like what you'll find in certain modern Infinitis, and the car features other bits of technology that are already available or coming soon to production cars such as augmented reality displays, a smartphone key system, electrochromic roof glass and reclining rear seats. Still, we think it's a distinctive concept car that could spawn some similarly distinct production cars. Lexus announced that between now and 2025, it will launch more than 10 new electrified models as conventional hybrids, plug-in hybrids or fully electric cars.

Google self-driving Lexus crashes into a bus

Google's self-driving cars have been in accidents before, but always on the receiving end... at least, until now. The company has filed a California DMV accident report (PDF) confirming that one of its autonomous vehicles (a Lexus RX450h) collided with a bus in Mountain View. The crash happened when the robotic SUV had to go into the center lane to make a right turn around some sand bags – both the vehicle and its test driver incorrectly assumed that a bus approaching from behind would slow or stop to let the car through. The Lexus smacked into the side of the bus at low speed, damaging its front fender, wheel and sensor in the process. This was a minor incident, and we're happy to report that there were no injuries. However, this might be the first instance where one of Google's self-driving cars caused an accident. If so, the Mountain View crew can no longer say it's an innocent dove on the roads -- while this wasn't a glitch, its software made a decision that led to a crash. We've reached out to Google to see if it can elaborate on what happened. No matter what the response, it was always going to be difficult to avoid this kind of incident. Until self-driving cars can anticipate every possible road hazard, there's always a chance that they'll either be confused or make choices with unexpected (and sometimes unfortunate) consequences. However, the hope at this early stage isn't to achieve a flawless track record. Instead, it's to show that self-driving cars can be safer overall than their human-piloted counterparts.Related Video:This article by Jon Fingas originally ran on Engadget, the definitive guide to this connected life.
