Toyota ready to design more heart-racing Prius

Long praised for its fuel economy and reliability, the Toyota Prius has been no stranger to less-than-flattering remarks about its styling and sense of excitement. In fact, the model is a regular movie punchline. For evidence, see Mark Wahlberg in The Other Guys or, more recently, Ice Cube in Ride Along. Apparently, Toyota President Akido Toyoda is getting the message and is pushing for what's been translated as a more "heart-racing" design for both the Prius and the Camry, the Canadian website Driving says. The Camry and Prius accounted for about a third of Toyota's US sales last year. With the Camry as the best-selling US model for each of the last dozen years, Toyota US head designer Kevin Hunter noted at the Detroit Auto Show last week that the Japanese automaker is looking for a "more emotional" design for the boxy sedan. The Prius redesign may have more constraints, as aerodynamics have to be factored in to ensure top-line fuel economy for the world's best-selling hybrid. Toyota used the Detroit show to show off the FT-1, a concept that many consider a preview of the new Supra. How this "Future Toyota 1" will affect the Prius and Camry redesigns, whenever they appear, remains in question but we like where things are headed.

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 takes i-Road tests to the streets of Tokyo

OK, here's where we think those road tests will start to get a little scary. Those super-narrow all-electric three-wheeled Toyota i-Road vehicles may have looked great sashaying through the towns of the French Riviera. But now? They're being tested in Tokyo. Hoo boy. The Japanese automaker says it'll start testing the i-Roads in the country's largest city on March 24 and will do so through early June. And while there will be some industry experts among the 20 participants, there will also be some regular folks who we hope won't find out the hard way how well those 660-pound, one-yard-wide vehicles perform in crash tests. In the meantime, we'll cross our fingers. The cool thing is that the i-Road now comes in five colors: blue, green, white, yellow and what looks like a magenta-fuchsia-type hue. Earlier this month, Toyota said it started testing the vehicles in Toyota City, Japan, as part of a broader program called "Ha:mo" where people link shared vehicles with public transportation systems (it stands for "Harmonious Mobility Network"). The three-wheeler was unveiled at the Geneva Motor Show early last year before getting the star treatment in a French Riviera-locale video.
