Toyota GT86 CS-R3 rally car presages for-sale customer racecar

Rallying may enjoy a very strong association with all-wheel drive, but it wasn't so long ago that the World Rally Championship was populated by cars that slipped and slid across gravel and tarmac using rear-wheel drive. One of those was the Toyota Celica. While the little Celica eventually joined the gravel-spewing masses with an all-wheel-drive rally car, Toyota is returning to its rear-drive rally roots with a modified version of the critically acclaimed GT86.
Called the CS-R3, the new model boasts all the necessary changes to turn the diminutive twin of the Scion FR-S and Subaru BRZ into a car capable of tackling the tough, twisting paths that are so routinely conquered by the world's rally cars. That means, of course, the CS-R3 has gotten a power bump.
Expected output sits between 240 and 250 horsepower, thanks to a new racing exhaust and manifold, as well as other changes. The ECU has been replaced with an item a bit more suited to racing, while the compression ratio has also been adjusted to boost the output.

Toyota still wants Tesla's battery help, still evaluating RAV4 EV program

Tesla Motors said earlier this month that the agreement it has with Toyota to supply battery packs for the Toyota RAV4 EV SUV would be finished by the end of the year. The deal is done, but Toyota is now singing its best version of Baby, Please Don't Go. The Japanese automaker may look to extend the battery-pack agreement with California-based Tesla, Automotive News says, citing comments made by Osamu Nagata, who heads Toyota's manufacturing and engineering in North America. Nagata also complimented Tesla for its "clear business strategy." Toyota, which owns 2.5 percent of Tesla, started the RAV4 EV collaboration in 2012, in which Tesla was to make about 2,600 battery packs for the all-electric SUV. That agreement was estimated to be worth about $100 million. "We are also evaluating the RAV4 EV program and will have more to say at a later date" – Toyota "We have a good relationship with Tesla and will evaluate the feasibility of working together on future projects," Toyota said in a statement e-mailed to AutoblogGreen. "We are also evaluating the RAV4 EV program and will have more to say at a later date." And while Toyota hasn't quite met initial sales expectations – it sold about 1,600 of the RAV4 EVs through this spring – the company expects to reach 2,500 by the end of the year. And the partnership did generate about $15 million in revenue for Tesla, according to that company's first-quarter letter to shareholders. That said, Tesla is obviously focusing its battery-making efforts on its own models.

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.
