Bhutan asks Nissan, Mitsubishi for help with massive EV-only plan

Originally, the somewhat modest plan was to introduce 2,000 electric vehicles to the capital of Bhutan. Then things got bigger when Renault-Nissan CEO Carlos Ghosn paid the country a visit and the Prime Minister of Bhutan, Tshering Tobgay, said his country, "will commit to a program to achieve zero emissions as a nation by a certain target date." Now we're approaching "holy huge" territory. Last week, Tobgay visited Japan to ask Nissan and Mitsubishi for help in possibly replacing every combustion vehicle with an all-electric option. "Gasoline is expensive and unfriendly to the environment." – Bhutan's Prime Minister At the very least, Bhutan wants to make more eco-friendly vehicles available. Tobgay told AsiaNews that, "Gasoline is expensive and unfriendly to the environment. Sustainable transportation will bring citizens happiness," which is something that a country that measures its Gross National Happiness is eager to track. Switching to electric vehicles makes complete sense in Bhutan, since the mountainous Asian nation produces more renewable hydro-electricity than it can use. Ninety-five percent of the zero-emission energy is exported to India, and Bhutan uses the profits to buy fuel from India to then power its vehicles. You can probably figure out for yourself how there's a simpler way to do this. News Source: AsiaNews.it Green Mitsubishi Nissan Green Culture Electric

New world record set with 507 EVs in parade [w/video] *UPDATE

Let's be honest, with more and more electric vehicles out in the world, it's getting easier to bring more and more of them together in one spot. Still, the work that goes into convincing over 500 EV owners to show up at one place at one time should be rewarded. And, in the case of the San Francisco Bay Leafs and Electric Auto Association Silicon Valley Chapter efforts yesterday as part of this year's National Drive Electric Week celebrations in in Cupertino, CA, the reward is a new Guinness World Record for the most electric vehicles in a parade. The number? 507 pure EVs gathered (sorry, plug-in hybrids). Recent similar records were set with now-small-looking events that had 305 cars or 431 EVs. The most recent target that the groups were trying to beat was a record originally set at the WAVE rally in Stuttgart, Germany earlier this year, where organizers also claimed to have 507 EVs. Plug In America (PIA) now says that the Stuttgart number was actually 481, giving California a 26-vehicle lead. The most unusual EV at the event was Stella, the solar-powered EV that is touring the world. PIA says that this four-person EV "can produce twice as much energy as it needs in a day," so it should feel right at home in the Golden State. *UPDATE: A previous version of this article said that the parade was organized directly by PIA. We have corrected the error. We've also added a video from Nissan about the parade below. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. NEW GUINNESS WORLD RECORD FOR NUMBER OF EVS IN A PARADE SET TODAY DURING NATIONAL DRIVE ELECTRIC WEEK IN CUPERTINO World Record set with 507 EVs, beating previous record by 26 CUPERTINO, Calif., Sept. 20, 2014-Philip Robertson, a judge with GUINNESS WORLD RECORDS®, today pronounced a new world record for most electric vehicles in a parade: 507. The record-breaking EV procession took place at the National Drive Electric Week event in Cupertino, Calif. Every vehicle was zero-emission, all-electric. No hybrid-electrics were allowed. 399 Panoramic view taken by Bruce Southwick. Stuttgart, Germany held the previous world record for a 481-EV parade in May 2014. "Congratulations on helping to drive the future of automotive technology," Robertson said upon presenting the Guinness certificate to a cheering crowd of thousands.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
