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.

Toyota found not at fault in alleged unintended acceleration crash

Toyota has already paid out millions and billions of dollars in settlements surrounding unintended acceleration, but the first lawsuit in the matter, which headed to a California court in July, has reached a verdict. Following the 2009 death of Noriko Uno, whose 2006 Camry was hit by another car and then sped out of control before crashing into a tree, the jury found that Toyota was not at fault in the crash.
Even though the 2006 Camry (shown above) wasn't involved in any of the unintended acceleration-related recalls and it was not equipped with a brake override, Automotive News reports that the jury's verdict says there was no defect in the car and actually blames the entire incident on the driver that ran into Uno's car - to the tune of $10 million. The accident started when the other driver ran a stop sign and hit Uno's car, and the report says that medical conditions (including diabetes) caused Uno to fail to stop her Camry.
The AN article also states that this lawsuit was a bellwether case for around 85 other personal-injury and wrongful-death suits against Toyota, but there are still many impending suits across the country. Scroll down for an official statement on this particular case from Toyota.

255-hp Toyota GR86 and other big news leaks in dealer presentation

Last month, Motor1 said it received information on Toyota and Lexus product plans for the next few years from an inside source who attended a dealer presentation. To protect the source, Motor1 didn't publish any slides or proof from that presentation. A snippet of what happened behind closed doors has found its way online, Allcarnews posting one of the slides yesterday, as well as its own recap of the Japanese automaker's plans that mirrors the Motor1 report. If all of this is true, not only is there a ton of product in the works, but Toyota and Lexus lineups will get more interesting while answering the requests of several enthusiast groups. We'll start with the 86, then go by model year after that. The next-gen coupe developed with Subaru should sit on Toyota's TNGA platform and get a rebrand to wear the GR86 name, for Toyota's Gazoo Racing division. The real hallelulah happens under the hood, where a turbocharged four-cylinder is expected to produce 255 hp, a 50-hp jump over the present model. Look for an upgraded interior, too. The debut is slated for summer 2021, possibly July.    This year: The fall season should introduce a new crossover and a new Sienna with hybrid powertrains only. The current minivan has been on sale since 2010, getting a minor refresh in front in 2018. The crossover will be a five-seat midsizer that brings back the Venza name, this model already rumored here and abroad. It, too, will only get hybrid powertrains. Both planned as 2021-model-year products, it's possible their motivations will be based on the 2.5-liter four-cylinder in both the RAV4 and Highlander hybrids. And a refreshed Camry might come later this year as a 2021MY sedan.  2021: Next year will be a busy one. ... On the Toyota side, and as TFL has reported, the all-new Tundra that's first to sit on the TNGA-F truck platform will show in December 2021 as a 2022MY pickup. Rumor has the top model powered by a 3.5-liter twin-turbo V6 hybrid with around 455 hp and 500 pound-feet of torque, perhaps distinguished by the i-Force Max name that Toyota recently applied to trademark. A few months before that, Toyota will roll out a Corolla-based crossover maybe called the Corolla Cross, and potentially built in the U.S. at the Alabama facility being constructed with Mazda. And remember, a Toyota exec teased a small hot hatch for this market as well, "an answer" to the GR Yaris sold in Europe, which Car and Driver figures will be based on the Corolla.
