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.

Redesigned 2014 Toyota Tundra spied testing in Canada

When Toyota first announced that it would be bringing the 2014 Tundra pickup to next month's Chicago Auto Show, we weren't quite sure if the truck would fall into the "all-new" or "refreshed" category. After seeing this latest set of spy shots, we're striking "all-new" from the record, but the enhancements do appear to be more than just a simple nip/tuck.
While the overall shape and greenhouse haven't really changed, heavy cladding found on the front fascia suggests that a totally redesigned nose is in store, with a fully reworked grille flanked by new headlamps. Smaller styling details are hidden by the big panels of camouflage, but we anticipate a few minor tweaks to the rest of the pickup's design when all that black tape finally comes off.
Mum's the word on powertrain enhancements (if any), as well as any changes that have been made to the chassis. But with the updated 2013 Ram 1500 already on the street, the recent unveiling of the updated 2014 Chevrolet Silverado and GMC Sierra twins, and a preview of what's to come from the likes of Ford, we certainly hope Toyota has injected enough new blood into its 2014 model year pickup to keep it competitive in this American-dominated segment. We'll know for sure come Chicago.

2015 Toyota Yaris to start at $14,845* and look like this

Toyota released a new Yaris in Europe and its Vitz clone in Japan a few months ago, so we knew it would only be a matter of time before it would launch the new hatchback here in North America. And that time has come.
The new, more distinctive 2015 Yaris features far more aggressive exterior styling, a look set apart by that large lower air dam and X-motif front end. It rides on a retuned suspension hooked up to an altogether more rigid chassis, and Toyota promises it will ride more quietly and comfortably than the model it replaces. Inside the new model has additional soft-touch materials in a more comfortable cabin equipped with everything from a 6.1-inch touchscreen display to nine airbags.
The 2015 Yaris comes in both three- and five-door bodystyles, and three trim levels that seek to eliminate the need for options packages. In fact the only option to speak of is a dealer-installed nav system. Power comes from a modest 1.5-liter four with variable valve timing, dual overhead cams and sixteen valves, sending 106 horsepower and 103 pound-feet of torque through either a five-speed manual or four-speed automatic.
