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.

Hello, Siri? Please don't crash the car

Hands on the wheel and eyes on the road? You could still be distracted while driving. Voice-recognition software that many automakers tout as a safer alternative to handheld devices can still divert drivers' attention, a new study published by AAA found. Researchers noted that workload ratings were the highest on their scales when participants in the study used Siri. The technology is alluring because it allows drivers to do things like change the radio station or compose a text message without removing their hands from the wheel or their gaze from the road. But many of those tasks increase a driver's cognitive workload. Depending on the situation, that can be dangerous. "It's especially problematic, because you can be distracted and not know it," J. Peter Kissinger, president of the AAA Foundation for Traffic Safety, told Autoblog. "That's the nature of mental distraction. It's hard to appreciate. ... Often, you don't know you're distracted until it's too late." There's significant variation in the results of the study. Simple, single-task car commands for operations like changing the radio station caused minimal increases in workload, about the same as listening to an audio book. Composing information using speech-to-text technology was more burdensome, and using menu-based functions caused a high level of cognitive workload. Siri-based interactions posed the highest levels of distraction, according to AAA. Researchers noted that workload ratings were the highest on their scales when participants in the study used Siri, and two of the three simulator crashes they observed during the study of 36 participants came while the subjects were interacting with Siri. The subjects weren't looking at nor making contact with their iPhones during these interactions. "Common issues involved inconsistencies in which Siri would produce different responses to seemingly identical commands," the researchers wrote. "In other circumstances, Siri required exact phrases to accomplish specific tasks and subtle deviations from that phrasing would result in a failure. ... Some participants also reported frustration with Siri's occasional sarcasm and wit." It wasn't just the complexity of the task that caused variations in level of distraction – the variations could also be dependent on the particular make and model of the car being tested.

Toyota reveals new TS040 Hybrid LMP1 [w/videos, poll]

There's a new season of motor racing upon us, and while that doesn't always mean a new crop of cars in every series, in the case of the 2014 FIA World Endurance Championship, that's exactly what it means. Porsche recently revealed its new 919 Hybrid and Audi its revised R18 E-Tron Quattro. Now it's Toyota's turn.
Revealed today at the Paul Ricard test track in the South of France, the new TS040 Hybrid is based on the TS030 Hybrid it replaces, redesigned to meet the latest regulations established by the FIA and ACO for the World Endurance Championship and its flagship race, the 24 Hours of Le Mans. In accordance with said regulations, the TS040 is two inches narrower than the TS030 and also incorporates a new hybrid powertrain.
The previous 3.4-liter V8 has been replaced by a 3.7-liter V8 developing 513 horsepower, and the new engine is coupled to an Aisin AW electric motor at the front, a Denso electric motor at the rear and a Nisshinbo super-capacitor that combine to kick out an extra 473 hp, giving the system a combined output of nearly 1,000 horsepower while consuming 25 percent less fuel than last year's car. It also gives the TS040 all-wheel drive to help channel all that power to the road.
