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.

2013 Toyota RAV4 earns 'poor' rating in IIHS small overlap crash test [w/video]

When the Insurance Institute for Highway Safety tested a batch of SUVs in its small overlap frontal crash test earlier this year, it held off on putting the Toyota RAV4 in the blender because the new, 2013 model was due to arrive shortly after the test. The new crossover might be better than it was before, but it could still only manage a rating of "Poor" in the test that has been a bugbear for a number of manufacturers.
Among other issues, the IIHS noted that the steering column moved seven inches to the right causing the crash test dummy to practically miss the airbag, the dummy's left foot was trapped in deformed sheetmetal and the dummy's head hit the instrument panel.
The 2013 RAV4 earned the Top Safety Pick rating by scoring well in the Institute's four other tests. A good score in this particular test would have earned it the Top Safety Pick+ rating that is so far only claimed by the 2014 Subaru Forester and 2013 Mitsubishi Outlander Sport in the SUV category. There's a press release below with more details and a video of the test.

Toyota RAV4 EV lease gets cut in half to $299/month

If you're in the market for a new electric vehicle, now is definitely the time to buy or lease. Following price drops on just about every other EV on the market, Toyota is looking to push a few more all-electric RAV4 crossovers out the door over the Labor Day weekend. The Detroit News is reporting that, through September 3, anyone looking to get into a RAV4 EV in Los Angeles or San Francisco, can get a deal: a $299 a month lease (no word on down payment, though) or zero-percent financing for 60 months for buyers.
The $49,800 RAV4 EV normally leases for twice as much - $599 a month - so this move could be an attempt to sell more of the 2,600 units Toyota has planned to produce. Or maybe, if you thought $599 was a fair price, you can now get two RAV4 Evs. Although temporary, the price drop comes at a time when many other EVs on the market have had their prices reduced, including the Nissan Leaf, Chevy Volt, Smart Fortwo ED and Honda Fit EV, not to mention already low prices for the Fiat 500e and Chevy Spark EV.
