Toyota asking NHTSA for fuel cell car safety exemption regarding electric shocks

Toyota is requesting an exemption from federal safety regulations that govern electric cars as it prepares to launch a small-scale hydrogen fuel-cell vehicle fleet.
The Japanese automaker is targeting Federal Motor Vehicle Safety Standard 305, which covers the packaging of high-voltage parts in electric cars. According to Uncle Sam, these systems need to be isolated so that passengers and first responders aren't electrocuted in the event of a crash. That seems pretty smart, but it's become a problem for Toyota's upcoming production fuel cell vehicle, as the mechanism that prevents electric shocks in low-speed crashes will apparently simply keep Toyota's car from even functioning.
Instead of the federally approved system, Bloomberg reports that Toyota plans to insulate the high-voltage wires and cables in the car, along with shielding electrical components like the fuel cells, electric motor and batteries with (presumably non-conductive) metal barriers.

A few pre-race notes and a lot of photos from the 24 Hours of Le Mans

The 82nd running of the 24 Hours of Le Mans is on.
Audi has won 12 of the last 15 events, the scion of Auto Union is trying to make it 13 this year. To do so, it will have to overcome a situation faced only three other times during its dominance of La Sarthe: underdog status. Toyota has won the first two races of the year and claimed pole for this race, the rumor being that this year it's Toyota's race to lose.
And then there's Porsche. It's been 16 years since the Stuttgart brand raced on the top rung at Le Mans, three years years since it announced its return, just a year since it acquired Mark Webber in a signing that wasn't subtle and a few months since we got eyes on the 919 Hybrid.

Toyota's new TNGA platform could boost Prius to 58 mpg

First, let's put the necessary context around the phrase, "Toyota New Global Architecture platform." The platform is important, but it is just one flowering bud sprouting from the real action, which is the production processes that will create it. It is crucial to understand that TNGA is fundamentally about a revolution in how Toyota designs and builds its cars - it even includes an overhaul of management and human resources - with one of the benefits being the new platform that the 2016 Prius will ride on. The Daily Kanban goes in depth about the changes, but integrated development for powertrain and platforms serves to reduces costs through more parts-sharing at the same time as it creates more cohesive platforms that are lighter, more compact, and have more efficient layouts. Regarding hybrids, Toyota says the new drive unit layout along with small components could raise hybrid efficiency "by more than 15 percent." That might enable the 2016 Prius to return 57.5-mpg combined - almost 59 in the city, 55 on the highway. Plus, the higher rigidity, lower center of gravity, and better suspension of the new platform will provide a better driving experience. All of these changes will be reflected in platforms for large and rear-wheel-drive vehicles, too. It is factory and build-process refinement that allows the development advances to be fully exploited. Toyota is making its lines more flexible, partly by having actual assembly lines that can easily be shortened, lengthened, or trucked somewhere else, and partly by introducing machines that can build parts for many different vehicles on the same line as needed, without using molds. The flexibility extends to capital investment, too, with much less money needed in order to switch to a new product build. Toyota says it is doing this to "improve core vehicle performance and product appeal," the overhaul making it simpler to produce new designs and features. Factory workers benefit from the flexibility as well; being able to build more types of cars means they aren't hamstrung by the sales fortunes of a small number of models.
