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.

2017 Toyota 86 Drivers' Notes | Fun, even with an automatic

The Toyota 86 is a car that enthusiasts begged Toyota to build for decades. It's small, lightweight and rear-wheel drive. Thanks to a partnership with Subaru that resulted in the BRZ, this stylish coupe hit the streets in 2012. In the U.S., the car was originally known as the Scion FR-S but was rebadged as a Toyota after Scion was axed last year. Along with a new name, the 86 received updated styling both inside and out as well as a revised suspension and a slight bump in power, at least for the manual models. This Hot Lava-colored car doesn't feature Toyota's slick six-speed manual. Instead it rocks a six-speed automatic with paddle shifters. While some enthusiasts may look down at that, automatics make up more than half of 86 sales. Still, the bones are there, and some people don't think the automatic is all that bad. Either way, we can't encourage enough people to buy these cars, as we want Toyota and Subaru to keep building them. Senior Editor, Green, John Beltz Snyder: When I first slid behind the wheel of the 86, I was surprised to see the gear selector and paddles. It's one of those cars that you don't think of as having anything but a manual transmission. Also, in an interior where all the controls and displays are underwhelming, a set of paddle shifters stands out as one of the few tactile objects in the cabin. I ended up using the paddles quite a bit, and found that I actually enjoyed using them, so much so that I'd actually consider opting for the automatic transmission were I to buy an 86. Despite shifts that aren't as razor sharp as they could be, the car's high-revving engine means that it still feels great to use. Riding an engine like this up to its redline, filling the cabin with noise, is the sort of thing that'll give you goosebumps. Being able to keep both hands on the wheel while shifting is a good thing for engagement in this car, based on my time with it. Plus, when I got stuck in traffic, I didn't have to wear out my left leg. The other brilliant thing about the Toyota 86 is its sense of balance. I loved the way it communicated its load distribution when cornering, whether on or off the throttle or brake. The fact that the nose of this car snaps right to where you want it when you start dialing in steering angle is satisfying. And its low stance and good view out the windshield make it really easy to place on the road.

Even Ferrari swept up in latest Takata recall expansion

The scope of Takata's deadly airbag problems continues to widen. Eight manufacturers announced recalls Friday that affect more than 12 million vehicles, according to documents filed with federal regulators. The automakers include Honda, which is recalling 4.5 million units, Fiat Chrysler with 4.3 million, Toyota with 1.65 million, and Subaru, which is recalling almost 400,000. Some of these cars include the Saab 9-2x and Pontiac Vibe that Toyota and Subaru made for General Motors. Mazda will recall 730,000 vehicles and Nissan has 400,000 affected units. The smallest numbers were posted by Mitsubishi, with 38,000 Lancers manufactured from 2006 to 2007, and as a noteworthy high-end manufacturer, Ferrari is calling back 2,800 vehicles. These are all US-market cars. Beyond America, the Japanese Transport Ministry has announced seven million additional vehicles will be recalled, which means 19.6 million vehicles across the globe are affected by recalls announced. The defects have been traced to an insufficiently manufactured airbag inflator, which lacks a drying agent that would prevent the inflators from deteriorating over time. Thirteen deaths have been linked to the faulty airbags, which have become unstable and are prone to exploding and showering vehicle occupants with lethal amounts of metal shrapnel. A private equity firm, KKR & Co., has been named in a possible buyout of the struggling Takata.
