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 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 twin-turbo V8 patent unearthed

An unremarkable patent focusing on a minor engine part has revealed that Toyota is at least considering a twin-turbo V8. While the filing is most likely just a large company protecting its intellectual property, it could also be a small glimmer of hope that Toyota, a storied company that's made some glaring missteps with enthusiasts in recent years, can leave the ICE party with a bang for the ages. The patent for a secondary PCV separator, whose function is to isolate exhaust gas from lubricating oil, was discovered by a member of the GR86 forum. In this case, it's not engine oil that's the culprit, but turbocharger oil. From a twin-turbo V8. The patent starts out with an almost embarrassingly hilarious stick figure drawing of a car and where said engine would be located (in the front, under the hood, duh). It has the words "Internal Combustion Engine" printed on a rectangle in case there was any doubt. However, the second figure shows a dual turbo setup nestled in the valley of a V8. It's a prime location for reducing turbo lag and optimizing throttle response (and should necessitate a substantial hood bulge as well). Now, interestingly, the forum member believes this engine will be installed in the next Tundra (and presumably Sequoia), but our own research indicates that the pickup will have a 3.5-liter twin-turbo V6 under the hood. With all due respect to the GR86 members, we're going to stand by that assertion and cross our fingers that the patent hints at something even better. That would be a high-performance Lexus, possibly an IS F or, if the ICE gods will allow it, an LC F. After all, we have had reports from Japan that a trio of F-cars were coming, including a LS F. It would explain why the 472-horsepower, V8-powered IS 500 was called the Sport Performance instead of full-on IS F. In fact, Lexus reps have promised that the F label would become even more performance oriented. A proper IS F would be a fitting sendoff to Toyota's high-performance V8, but the tested, then reportedly canceled, then reportedly revived LC F would be an even more melodious swan song. The flagship grand tourer could very well allow loyalists to forgive the aforementioned gaffes. Toyota president and noted car guy Akio Toyoda has taken heat for questioning the coming outright ban of ICE sales in his home country of Japan. Perhaps this engine is one of the reasons he's objecting.
