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.

2014 Toyota 4Runner

I recently took the redesigned 2014 Toyota 4Runner for a muddy romp in Pennsylvania. While the mechanical bits and pieces beneath the body-on-frame SUV trudge forward into the new model year with very few tweaks, the truck "receives a rugged new exterior design and interior refinements that add comfort and convenience without sacrificing its hallmark performance capability and excellent value," says the automaker.
A quick visual scan of the 4Runner reveals a new front end with a more "aggressive" and "muscular" appearance (yes, I'm quoting Toyota) that includes new headlights, grille and hood scoop. A roof rack is now standard across all trims, too. While SR5 and Trail grades have a bland color-keyed grille insert that gives the face a monochromatic appearance, the range-topping Limited (shown above and in our gallery) snarls with a silver-plated chin that gives it a bit more character.
New soft-touch surfaces within the cabin provide a more upscale environment and a bright new Optitron instrument panel improves readability and functionality. As before, the SR5 and Trail models arrive with fabric upholstery or optional Softex seats (synthetic leather). Genuine hides are reserved for the Limited trim, which is also fitted with Toyota's unique X-REAS (X-Relative Absorber System) automatic suspension system as standard equipment.

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.
