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.

BMW, Toyota outline new tech joint venture, new sports car

Back in June, Toyota and BMW announced a "memorandum of understanding" outlining plans for the two companies to join forces on future products and technology development. On Thursday, they signed a more formal and binding agreement that goes further into detail about the partnership, and it all sounds pretty exciting. The two announced they will work together in four main areas:
Joint development of a fuel cell system
"Set up a feasibility study to define a joint platform concept for a mid-size sports vehicle"

Editors' Picks March 2021 | Ford Mustang Mach-E, Polestar 2, Land Rover Defender and more

The month of March was unofficial minivan month here at Autoblog. We drove all of them but the Kia Carnival, but don’t worry, you wonÂ’t have to wait much longer to read that review. Among all the family-toting machines, we drove some more exciting vehicles including the Land Rover Defender and a pair of up-and-coming EVs. It was a month of excellent cars, meaning that this monthÂ’s litter of EditorsÂ’ Picks is stacked. In case you missed FebruaryÂ’s picks, hereÂ’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary or stand out in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in March that earned the honor of being an EditorsÂ’ Pick. 2021 Ford Bronco Sport 2021 Ford Bronco Sport First Edition View 32 Photos Quick take: Ford's baby Bronco is an authentic foil to the big Bronco 2-Door and 4-Door. It brings rugged styling, better-than-average off-road capability and thoughtful utility features to a generic segment of cars. Score: 8 What it competes with: Jeep Compass, Jeep Cherokee, Mazda CX-30, Subaru Crosstrek, Kia Seltos, Chevrolet Trailblazer Pros: Stellar design, excellent off-road, clever interior details throughout Cons: Pricier than most, average transmission, underwhelming interior quality and ambiance in lowest trims From the editors: Road Test Editor Zac Palmer — “I genuinely enjoy driving this cute crossover. It feels like a mini truck on the road, and Ford admirably translated the design from its big Bronco over to this Escape-based crossover. News Editor Joel Stocksdale — "The Bronco Sport isn't perfect, the transmission could use some work, and it's a little bumpy, but it's a characterful little thing with loads of style, great visibility and space, and impressive capabilities on and off road in the powerful Badlands form." In-depth analysis: 2021 Ford Bronco Sport Review | Bronco for the masses   2021 Land Rover Defender 2021 Land Rover Defender 110 View 64 Photos Quick take: The Land Rover Defender provides everything you'd hope for in a modern Land Rover: superlative off-road capability, surprisingly plush on-road demeanor, abundant interior space and abundant character. The base four-cylinder is likely all you'll need and lower trim levels provide more than enough equipment.
