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.

The 300-series Lexus LX will have V8, greater differentiation from Land Cruiser

For the first time in 64 years, there will not be a Toyota Land Cruiser sold in the U.S. The venerable off-roader is not in Toyota's 2021 American lineup, but the rest of the world will still get the next-generation Cruiser, called the 300 series internally, later this year. However, we may still receive a version of it badged as the Lexus LX. Here's what a new report suggests we might see. According to the Japan's Best Car magazine, the next LX will be more differentiated from its Land Cruiser cousin. The exterior is reportedly more distinctive, and the interior designed to be more suitable for a flagship luxury SUV. It'll still wear a version of the Lexus spindle grille, with different hood, fenders and quarter panels than the Cruiser. Naturally, the head- and taillights will differ as well. Most importantly, the LX will continue to use a ladder frame. Best Car says that the LX will continue to offer a 5.7-liter V8 good for 372 horsepower (which in the U.S. gives 383 horsepower). However, the Land Cruiser will ditch the V8 for a 3.5-liter turbo V6, offered with and without a hybrid system. Notably, the hybrid will not be the same as the one found in other Toyota cars, but a combination 10-speed automatic and motor that's more suitable for a heavy vehicle.  Last but not least, the report states that Toyota will also create a GR Sport version of Land Cruiser. Presumably, that means some dressier aero bits, larger wheels, and a suspension more tuned for highway, um, cruising.  The Land Cruiser is scheduled to debut in September 2021, while the Lexus may follow a couple of years later, despite being developed in parallel. The LX is considered to be more of a Lexus flagship than the LS sedan in many parts of the world, so it makes sense that Toyota will continue offering it. Related Video:

Green self-driving cars take center stage in Tokyo

Visions of cars that drive themselves without emitting a bit of pollution while entertaining passengers with online movies and social media are what's taking center stage at the Tokyo Motor Show. Japan, home to the world's top-selling automaker, has a younger generation disinterested in owning or driving cars. The show is about wooing them back. It's also about pushing an ambitious government-backed plan that paints Japan as a leader in automated driving technology. Reporters got a preview look at the exhibition Wednesday, ahead of its opening to the public Oct. 30. Nissan Motor Co. showed a concept vehicle loaded with laser scanners, a 360 degree camera setup, a radar and computer chips so the car can "think" to deliver autonomous driving. The Japanese automaker called it IDS, which stands for "intelligent driving system." Nissan, based in Yokohama, Japan, said it will offer some autonomous driving features by the end of next year in Japan. By 2018, it said vehicles with the technology will be able to conduct lane changes on highways. By 2020, such vehicles will be able to make their way through intersections on regular urban roads. Nissan officials said they were working hard to make the car smart enough to recognize the difference between a red traffic light and a tail light, learn how to turn on intersections where white lane indicators might be missing and anticipate from body language when a pedestrian might cross a street. Nissan's IDS vehicle is also electric, with a new battery that's more powerful than the one currently in the automaker's Leaf electric vehicle. Although production and sales plans were still undecided, it can travel a longer distance on a single charge and recharge more quickly. A major challenge for cars that drive themselves is winning social acceptance. They would have to share the roads with normal cars with drivers as well as with pedestrians, animals and unexpected objects. That's why some automakers at the show are packing the technology into what looks more like a golf cart or scooter than a car, such as Honda Motor Co.'s cubicle-like Wander Stand and Wander Walker scooter. Instead of trying to venture on freeways and other public roads, these are designed for controlled environments, restricted to shuttling people to pre-determined destinations. At a special section of the show, visitors can try out some of the so-called "smart mobility" devices such as Honda's seat on a single-wheel as well as small electric vehicles.
