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 teases mysterious RND Concept

Toyota is being very secretive about its newly teased RND Concept. The image above is all that the Japanese automaker is showing at the moment, and it's not much to go by. However, the wait to find out won't be very long, as the automaker is unveiling this very mysterious vehicle on January 26 in the UK. Making the RND even more intriguing is that this isn't just a concept pointing the way towards some nebulous future vehicle. Toyota claims that the model is production ready, and the automaker already has pricing, supply and manufacturing space prepared. We likely shouldn't expect a super luxury sedan or sports coupe, though, because Toyota says that the RND is meant for "the widest possible market." Could it possibly be some sort of inexpensive, electric vehicle like the Renault Twizy, then? With just the hind of a taillight, a slash of chrome and what might be an intake, there's not much styling work to go on here. Although, Toyota is making huge promises about the design; it claims the RND "has the potential to transform the look of every vehicle on the road." It's odd to see an automaker other than Tesla reveal a new vehicle outside of a major world auto show, which piques our interest about what Toyota is doing here. Read the company's press release below and let us know what you think the Japanese automaker is up to in Comments. THE NEW TOYOTA RND CONCEPT: SNEAK PREVIEW First details of new model released ahead of world debut next week Toyota is breaking with motor industry convention by revealing a new product outside the familiar surroundings of an international motor show. Instead its new RND Concept will make its world debut in the UK on 26th January, ready for fast-track development that should see it changing the face of motoring within weeks. The first image released today hints at how the concept's design marks a radical shift in direction for Toyota, taking the "fun-to-drive" qualities of its cars to a higher level. Although presented as a concept, Toyota acknowledges the RND will be unveiled in its production-ready form. Manufacturing and product supply have been secured and on-the-road pricing has been fixed at a level that will make the RND Concept accessible to the widest possible market. Toyota is confident, too, that the RND Concept's impact will go far beyond its own model range, having the potential to transform the look of every vehicle on the road.

Toyota might stop importing certain models if tariffs imposed

In case you hadn't heard, the entire automotive industry, both domestic and foreign, is very much against the automotive tariffs proposed by the Trump administration. And while the industry is lobbying hard against such tariffs, companies are also having to consider what to do in the event they are passed. CEO of Toyota's North American operations, Jim Lentz, told Bloomberg that the company will certainly be reconsidering its strategy in the event of tariffs between 10 and 25 percent the cost of the car. He told the news outlet that, depending on how high the tariffs are, Toyota might just increase the price of some models, or stop importing them altogether. Toyota does build a large number of its cars here in the United States. The Toyota Camry, Avalon, Tundra, Highlander, Sequoia, Sienna models are all built here, as well as some Tacomas, Corolla sedans, and Lexus ES sedans. Many of those vehicles are big sellers for Toyota, too, so that's good for the company. But many other Toyotas are built outside the country. The Toyota RAV4, Prius range, C-HR, Corolla hatchback, Land Cruiser, 86, Yaris, Yaris sedan, Mirai, 4Runner, and the entire Lexus line are built in other countries. Some of these imports we're sure are safe no matter how high the tariffs might be. The RAV4 is the company's biggest seller, and the Prius sells well, too. Even if the Prius wasn't selling so well, the company would probably still sell it simply because it's an image builder. Somewhat related, we imagine Toyota would continue offering a handful of Mirais. The 4Runner, C-HR and Corolla hatchback would probably be safe, too. If these models stick around after potential tariffs are imposed, expect their prices to increase. But in the Toyota line, anything that's not selling well and has tight margins is probably doomed. Chief among them are the French-built Yaris hatchback and the Mexican-built Yaris iA sedan. Both cars have terrible sales, and being low-end cheap cars, they'll only sell worse with higher prices, and Toyota will lose money if it has to eat the tariff. The 86 is a similar situation in which it's a niche vehicle that has had weak sales and is being sold at a relatively low price. The Land Cruiser could go either way. It sells in small numbers, but it's already extremely expensive and continues to sell. Buyers might not be put off by spending some more.
