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.

Aston Martin will race the Valkyrie hypercar at Le Mans in 2021

Aston Martin will challenge for outright victory in the Le Mans 24 Hours race in 2021 with its Valkyrie hypercar, the British luxury sportscar maker announced on Friday after race organizers rewrote the rules. The governing FIA, who oversee the World Endurance Championship, and race organizers Automobile Club de L'Ouest, revealed earlier that hypercar derivatives would replace prototypes as the top category starting in the 2020-21 season. Aston Martin will field two works Valkyries, powered by V12 normally-aspirated engines, as part of a multi-year commitment to a championship currently dominated by Japanese manufacturer Toyota. The announcement comes 60 years after Aston Martin's sole overall triumph at Le Mans in 1959 with Britain's Roy Salvadori and American Carroll Shelby. Le Mans winner Toyota, meanwhile, has committed to staying in the WEC after 2020 subsequent to the hypercar rules. The Japanese manufacturer said in a statement before this weekend's race at Le Mans' Sarthe circuit that it would continue in 2021 with a hybrid-powered prototype based on the GR Super Sport road car. Track testing of the new car will begin next year. Defending champions Toyota will start on pole position on Saturday after sweeping the front row in qualifying for the third year in succession. "This new era of competition is a fantastic opportunity to demonstrate our credentials not only as a race team against some of the best in the business, but also as a sportscar manufacturer," said Toyota Gazoo president Shigeki Tomoyama. The 2021 Le Mans will also be the 100th anniversary of Aston's first entry at the Circuit de la Sarthe. "I think you'd say from the brand's point of view, there's a little bit of unfinished business to be done," Group Chief Executive Andy Palmer told Reuters. Top Formula One designer Adrian Newey, who has won championships with Williams, McLaren and Red Bull, helped create the Valkyrie. The limited edition road legal version costs in the region of 2.5 million pounds ($3.17 million). "We don't under-estimate the difficulty of an outright win at Le Mans and you never under-estimate the tenacity and resources of Toyota," said Palmer. "On the other hand, we're not coming just to make up the numbers. We're coming here to give it a bloody good shot." Palmer said the new regulations would significantly reduce the costs of competing, without giving details about the likely budget, and hoped commercial rivals McLaren and Ferrari would take up the challenge.

Toyota pondering high-performance GT86 hybrid?

From what Autocar has to say, Toyota has even more plans for the GT86 beyond the convertible concept we just saw at the Geneva Motor Show. Along with a planned midcycle facelift, Toyota is reportedly looking at how to pack some extra ponies under the coupe's hood, and while there has already been a lot of talk about superchargers and turbochargers, it sounds like a performance-boosting hybrid system could also be in the works.
Talking to Toyota chief engineer Tetsuya Tada, Autocar has learned that the automaker is considering an electrical motor assist for the sporty coupe to improve performance without harming fuel economy. In attempting to keep weight - and, presumably, costs - down, the article mentions the use of a system closer to what Honda uses for its Integrated Motor Assist rather than a full Hybrid Synergy Drive system used in current Toyota hybrids. Tada says the added weight of the system could be offset by weight reduction, while aerodynamic changes and a lower center of gravity could improve the car's handling.
No word yet on whether a mild hybrid system would find its way to North America's Scion FR-S - let alone its Subaru BRZ twin - but the thought is certainly an intriguing one.
