J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.

Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.

Recharge Wrap-up: LA Auto Show may feature updated Cadillac ELR, Uber expands Chicago HQ

A Kentucky man has converted his 1939 Dodge pickup to an electric vehicle. Al Gajda of Lexington built the electric truck, which he now uses as his daily driver. "I take advantage of any excuse to drive it; just banging around town, errands, short runs on the interstate, delivering my granddaughter to school in the morning," he says. It is powered by a lithium-ion phosphate battery, which is mounted in a wooden box on the truck bed, and gets about 100 miles per charge. Read more at the Lexington Herald-Leader. Elon Musk will speak at the Automotive News World Congress in January. The Tesla CEO is a featured speaker for the program, "Setting the Pace in a Thriving Market." The event takes place in Detroit, which could lead to an interesting mix of people in the audience, and Musk will speak on January 13. Read more at Automotive News. Production of the Toyota Rav4 EV has ended. The shipment of the final Toyota EVs concludes Toyota's deal to source batteries from Tesla. Of the 2,600 Rav4 EVs to be produced, there are probably just a few hundred left to be sold, most of which are likely to be gone by the end of October. Read more at Inside EVs. Cadillac will likely show an improved version of the ELR at the Los Angeles Auto Show in November. The 2016 ELR will include unspecified "engineering enhancements," according to Cadillac spokesman David Caldwell. There will be no 2015 model, as the 2014 model will be sold until the 2016 ELR goes on sale in the first half 2015. Read more at Edmunds. Uber executives, along with Illinois Governor Pat Quinn, have announced a major expansion of the ride-hailing company's Chicago headquarters. Uber also plans to add 420 jobs by the end of 2016. "Uber's new expanded headquarters will allow the company to continue its rapid growth and serve its riders and drivers throughout Illinois," says Governor Quinn. Last month, Quinn vetoed legislation that would have put restrictions on companies like Uber in the state. Read more in the press release below. Governor Quinn and Uber Announce Major Chicago Headquarters Expansion Innovative Ridesharing Company to Add 420 Jobs by End of 2016 CHICAGO, Sept. 29, 2014 /PRNewswire-USNewswire/ -- Governor Pat Quinn and Uber executives today announced that the ridesharing giant is moving forward with creating 420 new jobs by the end of 2016 in a major expansion of its Chicago regional headquarters.
