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.

Tokyo wants 6k fuel-cell cars from Toyota and Honda for 2020 Olympics

Japan aims to have greener cars on its roads in time for the 2020 Tokyo Olympics, and the city government there is putting some serious money on the table to make sure that the transformation happens in time. The push could jump start sales of hydrogen fuel cell vehicles (FCEVs) in the metropolis and would portray the Asian country as a leader in the cutting-edge tech. The city is setting aside 45.2 billion yen ($385 million) to offer subsidies for people buying FCEVs and to build 35 hydrogen refueling stations to keep them going, according to Bloomberg. The local government is in talks with Toyota and Honda to have 6,000 fuel cell vehicles on the road in time for the games. These generally expensive factors are often considered some of the biggest hurdles for the alternative fuel to take hold. Beyond the 2020 games, the Tokyo government has even more aggressive plans for the alternative fuel. The city's audacious goal is to have 100,000 FCEVs, 100 hydrogen-fueled buses and 80 refueling stations in the capital by 2025, according to Bloomberg. The city wants to offer FCEV buyers incentives as much as about 3 million yen ($25,325) with a third of that money coming from the Tokyo government and the rest from the national government, according to Bloomberg. Furthermore, subsides on building refueling stations could be as high as 80 percent in Tokyo, which puts costs more in line with building a traditional gas station. It appears that the demand is already building to make Tokyo's goal a reality. Toyota has received around 1,500 orders for the Mirai, according to Bloomberg. Although, the majority have come from the country's government or fleets. To meet the higher-than-expected demand, the automaker expanded its production facilities by adding two more assembly lines. The launch of Honda's latest FCEV was recently pushed back until March 2016, a year later than originally expected.

Weekly Recap: Things you might not know about the 2015 Dodge Charger and Challenger Hellcats

If you're an enthusiast, and you don't know that Dodge spawned another Hellcat this week, you really must have been living in cave. The 2015 Dodge Charger SRT Hellcat is probably the biggest news for enthusiasts since the reveal of, well the 2015 Dodge Challenger SRT Hellcat.
But, there are some things you might not know or might have missed about the new Charger and Challenger Hellcats. For starters, reports that the Hellcat production would be limited to a low volume are not true.
"We have not capped the Hellcat on either the Challenger or the Charger," Dodge CEO Tim Kuniskis said.
