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.

Supra successor may be all-electric sourced from Tesla; MR2 returning too?

Rumors of a revival of the Toyota Supra and MR2 have been swirling for years right up until just this week when high-level Toyota employees all but confirmed their return.
But now The Detroit Bureau has put together news from different sources suggesting that the next Supra might be all electric. The report cites recent comments from Toyota senior executives hinting at plans to work with Tesla on a new joint project. The FT-HS Concept (shown above) seems a logical inspiration for a new Supra.
And on the other side of the equation is Tesla's design chief Franz von Holzhausen who was quoted last year saying his company was looking at its next project, probably a sports car, that would follow next year's intro of the Model X. He went on to suggest the car would compete directly with BMW's 3 Series, which, in coupe form, could be a worthy competitor to a Supra as well.

Recharge Wrap-up: Honda Grace hybrid goes on sale in Japan, Daimler spends 100M euros on batteries

The Mercedes-Benz S-500 Plug-In Hybrid has earned an Environmental Certificate from the TUV Sud technical inspection authority. The award is based on a lifecycle assessment of the vehicle. This includes the ability to reduce CO2 emissions by 43 percent through charging, and by 56 percent if charged using hydroelectricity. Read more in the press release below. Daimler is expanding its production capacity for lithium-ion batteries. The company is investing around 100 million euros in its subsidiary Deutsche ACCUmotive, who will provide batteries for the electric Smart Fortwo and Forfour, as well as various Mercedes-Benz models. By the end of the construction, Deutsche ACCUmotive will have quadrupled production and logistics space since 2011. Read more in the press release below. Honda has begun sales of its Grace hybrid sedan in Japan. The Grace is based on the Honda Fit and uses the automaker's Sport Hybrid i-DCD system. It comes in front- and four-wheel-drive versions and uses a seven-speed DCT with built-in motor. The Honda Grace starts at the equivalent of about $16,500. Read more in the press release below. Honda has begun operation of its wind farm in Brazil. The farm consists of nine wind turbines, expected to produce about 95,000 MWh of electricity per year, which is on par with Honda's consumption for automobile production in the country. Honda is aiming to cut its CO2 production by 30 percent by 2020 compared to 2000 levels. Read more in the press release below. Toyota has won the 2014 World Endurance Championship's Driver and Manufacturer categories with hybrid technology. Toyota celebrated the win after the final race in Sao Paolo, Brazil. Toyota uses the same hybrid technology in its racing cars as it does in its production vehicles. Read more in the press release below. Controlled Power Technologies and other groups are calling for an international 48-volt electrical standard for vehicles. The groups called for the standard at the International Conference Automotive 48 V Power Supply Systems, saying that the 48V standard for mild hybrids would help make the systems more affordable. This will make it easier for automakers to meet the more stringent CO2 standards anticipated in coming years along with the introduction of the World Light vehicles Test Procedures.
