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.

2014 Toyota Aygo marks the spot [w/video]

Following the leaked pictures we showed you yesterday, we have the full battery of images and info of the all-new Toyota Aygo, in addition to our gallery of live photos from the floor of the Geneva Motor Show.
Like its cousins from Peugeot and Citroën, the Aygo foregoes a diesel engine in favor of a highly efficient gas powerplant. The 1.0-liter naturally aspirated 4-cylinder turns out 68 horsepower and 70 pound-feet of torque. When it hits the market, it'll be with either a five-speed manual transmission or a five-speed, X-Shift automated manual. The former will help the Aygo return 57.3 miles per gallon and hit 62 miles per hour in 14.2 seconds. Opting for the X-Shift variant will net drivers 56 mpg, with 62 arriving in a leisurely 15.5 seconds.
We'll admit, aside from the fuel efficiency, there's nothing terribly great about those numbers. Still, with its compact dimensions - it's only 136 inches long - and a curb weight of no more than 2,000 pounds, it should prove tossable in the bends.

Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further. You can watch an animated video of the piston in action here (click on "Outline") and see the SAE papers here and here. More technical details are available at Green Car Congress.
