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.

Autoblog Minute: UAW and FCA avoid strike, Clarkson teases new show

FCA avoids a worker strike, a former Top Gear host teases us with a picture from Amazon's new car show, and Toyota predicts autonomous cars by 2020. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] FCA avoids a worker strike, a former Top Gear host teases us with a picture from Amazon's new car show, and Toyota predicts autonomous cars by 2020. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. A UAW strike of FCA was avoided thanks to a zero-hour tentative agreement reached this week. Worker concerns that were renegotiated in the new [00:00:30] deal include adjustments to the two-tier wage scale, health care costs, and production outsourcing. Now check-in with Autoblog as we update our reports on this evolving story. Shooting began on Amazon Prime's new automotive show starring the former Top Gear crew. That's Jeremy Clarkson, Richard Hammond, and James May. Now Clarkson threw out a tweet from day one of filming on location at Algarve Motor Park in Portugal. The picture features the show's [00:01:00] three stars and crew posing with the holy trinity of hyper cars. That's a McLaren P1, a Ferrari LaFerrari, and a Porsche 918 Spyder. This Prime show is being called Gear Knobs though the name is unofficial. Now if a tweet is any indication of what we can expect, who cares what it's called this is gonna be awesome. (Eds Note: Clarkson tweeted Friday that the show will not be called Gear Knobs.) Toyota predicts drivers could be obsolete on highways as early as 2020, with technology dubbed the Toyota Highway Teammate or THT. Toyota is using a modified [00:01:30] Lexus GS to show what this is capable of. THT is already able to create a driverless freeway car that's capable of changing lanes, making passes and taking curves. Plus, it can keep safe distances from other vehicles. Toyota is currently testing this on Tokyo's Shuto Expressway. Those are the highlights from the week that was. Be sure to check out my full recap this Saturday. And I'll have some added insight on the BMW M4 GTS. For Autoblog, I'm Greg Migliore. [00:02:00] Show Logo Autoblog Minute is a short-form video news series reporting on all things automotive.

Autoblog Minute: VW finds CO2 'irregularities', Takata dropped by automakers, SEMA recap

Volkswagen's diesel emissions scandal gets a new wrinkle, US regulators hit Takata Corporation with a substantial fine, and we head to Las Vegas for a look at tuner paradise at the 2015 SEMA show. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] Volkswagen's diesel emissions scandal gets a new wrinkle. US regulators issue a significant fine to Takata Corporation. And we take a peek inside tuner paradise at the 2015 SEMA show. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. The VW diesel emissions scandal, first brought to light in September, gets a new wrinkle, as an internal investigation by the German automaker revealed [00:00:30] irregularities in CO2 emissions that could affect approximately 800,000 vehicles. VW estimates the issue could pose a 2-billion euro economic risk. VW claims that most of the vehicles affected have diesel engines, but industry analysts say a 1.4-liter gas engine is also affected. VW says that fuel consumption figures were set too low during the CO2 certification process. During all of this, sales of some diesel-powered Volkswagen, Audi, and Porsche models [00:01:00] have been halted. Takata Corporation is back in the news in connection with its deadly airbag scandal. Federal regulators fined Takata $70 million. If the parts supplier does not comply, the fine could balloon to $200 million. Takata was also dropped this week by its biggest customer, Honda. And now, Toyota and Mazda will be following Honda's lead in dropping Takata. We're also hearing that Mitsubishi and Subaru are considering a switch in air-bag inflator suppliers. SEMA 2015 [00:01:30] came and went. We saw offerings from Mopar, like the AWD Challenger concept. Honda unveiled a Ridgeline that it will race at the Baja 1000, which gives us a hint at what future production model could look like. The celebrity presence was also felt in Vegas as it always is. Kid Rock brought a Duramax Diesel Chevy Silverado, and Acura restored and presented Ludacris with his now famous 1993 Acura Legend. Those are the highlights from the week that was. Be sure to come back on Saturday for my full recap, [00:02:00] where I'll have some added insight into Hyundai's foray into the luxury sector. For Autoblog, I'm Greg Migliore.
