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.

America was the unexpected theme at the 2017 Detroit Auto Show thanks to Trump

President-elect Donald Trump was not in attendance at this year's Detroit Auto Show, but it sure seemed like he was the target audience for many of the press conferences and announcements surrounding the event. Several manufacturers chose to play up existing and future commitments to the US in general and American jobs specifically in their presentations to the press, and we're pretty sure that has everything to do with Trump's recent targeting of automakers on Twitter. To us, it seemed automakers were going on the offensive to try and preempt any future tweet-shaming for investing in auto manufacturing anywhere but the US. The pro-America sentiment started the week prior to the auto show, with Ford announcing that it would build several future electrified vehicles at its Flat Rock Assembly Plant in Michigan and also cancel a $1.6 billion factory planned for Mexico. Ford announced the two items on the same day, but the reality is that they likely have no relation to each other; the Mexican plant is being skipped because the company doesn't need the extra capacity to build the Ford Focus right now. Trump was still happy to share the news on Twitter. Then, on Sunday, FCA announced it would invest $1 billion in manufacturing plants in Ohio and Michigan to produce the new Jeep Wagoneer, Grand Wagoneer, and Wrangler-based pickup. It's not as though those potential new jobs were on their way out of the US, necessarily, but FCA took the opportunity to mention that plant upgrades at the Warren Truck Plant would allow the company to build Ram heavy duty trucks, which are currently assembled in Mexico, there. CEO Sergio Marchionne confirmed that Trump and his proposed tariffs had nothing to do with the decision. We certainly believe that, but we also have to believe that the timing of the release, positive outcome for America, and zero gain for Mexico were all orchestrated. Again, Trump sent out a victory tweet as if this had been his doing. Ford then used its press conference at the show on Monday to reiterate the plans for Flat Rock and also confirm that the Ford Bronco and Ranger nameplates will be returning to the US market, and that both will be built at a plant in Michigan. Announcements of manufacturing locations are usually aimed at the UAW, which certainly has a stake in these things, but again this one was broadcast to the auto show crowd in general.

Airbag recall adds 85k Pontiac Vibes to tally

The repairs needed for the faulty airbag inflators supplied by Takata continue to expand. Toyota initially announced a recall of 766,300 vehicles equipped with the bad part on June 11 as a followup to a campaign from 2013. Soon after, the National Highway Traffic Safety Administration opened a preliminary evaluation into five automakers who also used the component in their models. Now, NHTSA has released the official announcement of the latest Toyota recall listing 844,277 affected cars, including the newly added 2003-2004 Pontiac Vibe.
While NHTSA's document didn't include a model-by-model breakdown, General Motors spokesperson Alan Adler estimated to Autoblog that roughly 85,000 Vibes in the US would be covered under the latest recall. Like the rest of the affected models, the airbag inflator could rupture in a crash causing the bag not to work correctly, possibly spraying metal fragments at the occupant.
Toyota spokesperson Cindy Knight told Autoblog that the reason for the disparity between the earlier press release and NHTSA document was that Toyota was continuing to comb through VINs to create a list of affected vehicles. The original number was an estimate of that process at the time. Scroll down to the recall report from NHTSA.
