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 GT86 engineer Tada recounts how sports car came to be

Because the Toyota GT86, Scion FR-S and Subaru BRZ coupes are now a reality, it's almost hard to imagine the struggle that had to happen within the large, conservative corporate structures at both automakers for the joint project to even get off of the ground.
Speaking to those struggles on Toyota UK's Toyota Blog, GT86 Chief Engineer Tetsuya Tada enlightens us with a recap of the sports car's earliest origins. For Tada, the first stages of the project must have seemed almost as dreamlike as the final product is to drive.
Said the Chief, "I had been working in the minivan department engineering new product, but a month after the meeting I was summoned. 'Forget about minivans,' they said, 'you are now working on the sports-car project.'"

McLaren, Koenigsegg, Toyota, Ford, Dodge and Corvette Lego kits announced for 2021

Lego has announced a slew of car-themed sets for 2021. The six kits comprise nine vehicles and fall under the brick pusher's Speed Champion line of official OEM-licensed kits. News of their arrival comes from German toy retailer JB Spielwaren's pre-order listings, which show three single-car sets and three dual-car sets of matched marques. Starting with the McLaren Elva roadster, the kit consists of 263 pieces and is finished in blue. It seems to have a difficult time capturing the curves of the real-life Elva, but there's only so much you can do with a bunch of plastic blocks. Lego has made several other McLaren kits before, including the Senna, 720S, and a more advanced Senna GTR for the Technics line. Next up is the Koenigsegg Jesko, made up of 280 pieces and finished in white. Though the real-life Jesko is still curvy, this kit does a better job of replicating its aggressive maw, vents and cantilevered rear wing. Rounding out the single-car sets is the 299-piece Toyota GR Supra in yellow. This marks the first time Toyota has lent their license to Lego. Again, it struggles a bit to represent the curvy Supra, relying on printed details like logos and headlights to identify. On the other hand, the Chevrolet two-car does a stupendous job with the 1968 Corvette. The C3 is instantly recognizable as such. The C8-R race car it's paired with suffers from the same issues as some of the previous cars, though. The set contains 512 pieces, and funnily enough the C8 driver has short hair while the C3 driver sports a period-correct wavy mane. The next set is a 627-piece Mopar-themed pair, including a purple (Plum Crazy?) 1970 Dodge Challenger T/A and an SRT top fuel dragster. The race car is spot on, but the Challenger was probably tough to make given the width restrictions. It looks a couple of pegs too narrow compared to the wide proportions of the real deal. Last but not least, the Ford set contains a Bronco R and Ford GT Heritage Edition. Consisting of 660 pieces, the set does an excellent job of representing both cars. The GT looks faithful in its Gulf livery, and the Bronco R looks more like a real Bronco than the actual Bronco R race truck. All in all, it's always fun to see more Lego sets with real cars, and we're glad to see more manufacturers added to the roster. The single-car sets are recommended for ages 7 and up, while the double-car sets have an 8 years and up rating. Price in U.S.
