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 has two all-new 8-passenger SUVs in the works, and one's a Lexus

Toyota announced yesterday that its Princeton, Indiana, manufacturing plant is getting a big $803 million infusion of cash. The reason? Toyota casually dropped that it will soon build “two all-new, three-row SUVs” there. TheyÂ’ll be “designed with the active Gen Y American Family in mind,” which is another way of saying that Toyota is targeting Millennials. In case you missed it, Millennials are in their late 20s and 30s now! That means they have growing families and need more space to put them. Both new SUVs will seat up to eight passengers. The other big reveal is that both will be electrified. WeÂ’re going to assume that means theyÂ’ll be regular hybrids in ToyotaÂ’s case, though thereÂ’s every possibility for a PHEV “Prime” version, too. Both will have semi-automated driving systems, advanced enough that they will “allow for hands-free driving in certain conditions.” Plus, there will be a remote parking system that allows “the driver to park and unpark outside the vehicle using a smartphone.” The last nugget of tech Toyota is sharing with us is that both will use a new “digital key” that turns your smartphone into a quasi key and allows you to share it digitally with others. Another bit of information concerning these two is that one will be a Toyota, and the other will be a Lexus. What these two models will be named is not yet clear. Seeing “three-row SUV,” our minds instantly go to Sequoia. That model is as old as it gets these days, and is deeply in need of a redesign — the current generation launched all the way back in 2008. However, Toyota does not explicitly say that this news pertains to the next-gen Sequoia. In fact, previous reports of the Sequoia shifting its production location to San Antonio lead us to believe that this news has absolutely nothing to do with a potential next generation of the SUV. Coincidentally, the Sequoia is currently built at the Princeton, Indiana, plant thatÂ’s getting this investment — that official switchover to Texas is reported to happen sometime in 2022.  ToyotaÂ’s language in this press release, plus the knowledge that Sequoia is leaving Indiana, all indicates that these two three-row SUVs might not be rough-and-tumble body-on-frame off-roaders. TheyÂ’re likely going to be plenty capable (hitting that “active lifestyle” market), but the focus toward families suggests that comfort could be paramount.

2015 Toyota Sienna

It's hard to love a minivan, but it's very, very easy to use one. More than any other kind of vehicle - save a panel van, perhaps - the minivan is the most appliance-like of four-wheeled transportation devices. And most minivan buyers don't need to love their purchases; they just need to use them. So when it comes to a minivan's driving dynamics, who cares?
Well, we do. So we perked right up when Toyota talked about refinements it made to the 2015 Sienna, starting with some 142 added spot welds made to the body structure. Normally not stop-the-presses stuff, but Toyota says the added reinforcements prompted Sienna engineers to recalibrate the springs and shocks for improved handling, and our very limited wheel time along the (admittedly benign) roads on the Big Island of Hawaii revealed the 2015 Sienna SE model's handling to be tidier and more engaging than you'd expect for a porky, 4,560-pound, eight-passenger box on wheels.
