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.

How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.

2014 Toyota Aygo marks the spot [w/video]

Following the leaked pictures we showed you yesterday, we have the full battery of images and info of the all-new Toyota Aygo, in addition to our gallery of live photos from the floor of the Geneva Motor Show.
Like its cousins from Peugeot and Citroën, the Aygo foregoes a diesel engine in favor of a highly efficient gas powerplant. The 1.0-liter naturally aspirated 4-cylinder turns out 68 horsepower and 70 pound-feet of torque. When it hits the market, it'll be with either a five-speed manual transmission or a five-speed, X-Shift automated manual. The former will help the Aygo return 57.3 miles per gallon and hit 62 miles per hour in 14.2 seconds. Opting for the X-Shift variant will net drivers 56 mpg, with 62 arriving in a leisurely 15.5 seconds.
We'll admit, aside from the fuel efficiency, there's nothing terribly great about those numbers. Still, with its compact dimensions - it's only 136 inches long - and a curb weight of no more than 2,000 pounds, it should prove tossable in the bends.
