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.

Scion FR-S Convertible (in Toyota GT86 form) spied in South Africa

Though the eventual existence of a convertible version of the Toyota GT86 (and its Scion FR-S and Subaru BRZ versions for America) is a no-brainer, we've yet to get a glimpse of the real-deal car until now.
Spotted in Cape Town, South Africa, of all places, this completely undisguised GT86 convertible seems to be in a remarkably advanced state of development. The image seen here was obviously sniped from quite a distance and without the aid of a powerful lens, but we can still make out a production-ready looking piece of rear bodywork for the convertible top to hide away in, as well as a functioning trunk lid. It's hard to make out with any certainty, based on this evidence, but there does seem to be space retained behind the front seats for two, small rear chairs.
With the first car spotted, we'd expect to seem some more and better images of it flow through in the near future, and if not, Toyota has already confirmed a concept version for next month's Geneva Motor Show, dubbed FT-86 Open, so stay tuned. For now, click through to the FT86Club.com forum to have a slightly closer look at the images.

Recharge Wrap-up: Qualcomm invests in Chargemaster, gamers will appreciate these Toyota Prius C ads

Chargemaster has received an investment from Qualcomm for wireless charging in the UK. Of the 27,000 charging stations it has already installed, 10,000 are ready to be adapted for inductive charging, according to Chargemaster. Dr. Anthony Thomson of Qualcomm says that with this investment (of a currently undisclosed amount), "we are taking another step towards deployment of a convenient and easy to use WEVC network." The convenience of wireless charging not only makes life easier for current EV drivers, but could also help convince more people to make the switch to electric driving. Read more at EV Fleet World or at Hybrid Cars. Toyota has released Japanese ads for the Prius C using music from popular video games. The ads, which borrow scores from Dragon Quest III and Monster Hunter, also use the tagline "Fun to drive, again." While some may find the link between driving and role-playing video games tenuous, fans of green cars and gaming know the various feedback displays in cars like the Prius C can make eking out every last mpg possible feel like a game, with the car's Eco Score essentially the equivalent of a game's high score. Plus even if the reference is lost on a viewer, the ads do instill a sense of adventure. See and hear for yourself in the videos below, and read more at Kotaku. The electric vehicle charger (EVC) market is predicted to grow by significantly worldwide by 2020, according to a new report. It shows a predicted compound annual growth rate of 28.28 percent between 2013 and 2020. Level 2 charging station sales will expand from $0.2 billion in 2014 to $3.5 billion by 2020, while growing from $67 million in 2013 to about $947 million in 2020 in the US alone. For 2014, residential EVC sales currently make up 70 percent of those in the US, while sales between home and non-residential level 2 chargers is expected to be about equally divided by 2020.
