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.

2015 Toyota Prius V gets updated looks and content

The Toyota Prius V is the most utilitarian member of the Prii family with a big jump in cargo space over the rest but maintaining the great fuel economy. For the 2015 model year, the company is giving the wagon an update with a big shift in front end styling and upgraded taillights to go with the revised look. Inside, customers also get a little new technology, as well. The biggest change up front is the reshaped headlights and new bumper that look almost identical to the recent restyling of the Prius + in Europe. Though, the latest parts might be a little polarizing and almost make the wagon look like it has gills at each corner. The top level Prius V Five trim also adds integrated foglights to the design and headlights with LEDs for the high and low beams. Toyota is offering three additional colors too: Attitude Black Metallic, Absolutely Red and Toasted Walnut Pearl. Inside, drivers can get a new, eight-way adjustable power driver's seat on some models, and there's now a 4.2-inch TFT screen situated between the gauges on the Three trim level and higher to display information like fuel economy, navigation instructions, climate control settings and more. The upper versions also get Toyota's latest Entune infotainment system with a 6.1-inch high-res touchscreen with navigation. Finally, the Advanced Technology Package on the Five trim now includes Lane Departure Alert and Automatic High Beams. Mechanically, the Prius V remains unchanged thanks to the same 1.8-liter Atkinson-cycle, four-cylinder hybrid powertrain with nickel-metal hydride battery pack pumping out 134 net horsepower. Fuel economy stays at 44 miles per gallon city, 40 mpg highway and 42 mpg combined. Despite the upgraded looks, the base 2015 Prius V Two is $75 cheaper this year at $26,675, plus $825 destination. Although, the top Five model is $540 more at $30,935 before destination. The latest model year should start hitting dealers in December; scroll down for all of the specs and pricing.

Toyota to start production of hydrogen vehicles in December

Toyota's hydrogen fuel cell vehicle will be in showrooms sooner than planned, the Japan Times reporting that production will commence in mid-December with the sedan following "by the end of this year." No reason was given for the new timeline; Toyota has been saying all along that we'd see it in 2015.
The company is said to be "considering" production volume of "dozens of... vehicles per month" at a "likely" price of eight million yen, which is $78,030 US. That is well in line with the numbers thrown around last year, when the target was somewhere between $50,000 and $100,000. Then late last year, during our first drive of the FCHV mule, we wrote that "the official quote... [is] that a price of 'less than 10 million yen is ideal.'"
That alleged $78K is a sizable sum to be one of the early adopters on the hydrogen fuel cell wagon train, but with things moving around so much - and with Toyota publicly citing hydrogen fuel cells as the future - there's plenty of reason to be cautious about that number.
