Nissan e-NV200 electric van will start FedEx testing in DC

The electric van test program that Nissan and FedEx announced today at the Washington Auto Show isn't really all that new. After all, FedEx is already testing the all-electric e-NV200 in Singapore, Japan and Germany. The news today is that FedEx will be one of the first companies to test the EV in the US, and Nissan brought a prototype to the show to gin up interest. 200 CHAdeMO stations were added in December, a monthly record. The e-NV200 uses a powertrain similar to what's in the Nissan Leaf and weighs about the same as that passenger car, but Nissan isn't talking about US performance figures quite yet. Nissan isn't even saying if the vehicle will even come to the US, but this test program sure hints that something like that is in the works. For now, all that's official is that Nissan will bring two - yes, just two - e-NV200 units to the US, letting FedEx test one in the Washington, DC area for between six to eight weeks before cycling the EVs to other companies in the US over the next year. The idea, as you may have guessed, it to gather data on how companies might use this van and let Nissan figure out if it wants to sell the e-NE200 here. The van will start being built in Barcelona, Spain this spring and is currently intended for Europe and Japan. FedEx is no stranger to greener vehicles, and has 167 EVs in its US fleet right now. Read more in the press release below. The e-NV200 can use CHAdeMO fast charging, and Nissan said today that it has helped install 570 of those DC fast chargers in the US since announcing expansion plans last year. At the time, the target was 500 chargers in 18 months, so things are progressing faster than publicly anticipated. In fact, 200 CHAdeMO stations were added in December, a monthly record. Jan. 22, 2014 Nissan and FedEx Express Put All-Electric e-NV200 to Work in Collaborative U.S. Test WASHINGTON, D.C. - FedEx Express, a subsidiary of FedEx Corp., and Nissan announced today at the Washington Auto Show that the two companies will begin testing the Nissan e-NV200, a 100 percent electric compact cargo vehicle, under real world conditions in Washington, D.C. This test marks the first time the vehicle will be running in North America. FedEx Express and Nissan have conducted similar e-NV200 tests with fleets in Japan, Singapore, the United Kingdom and Brazil. FedEx and Nissan are both committed to reducing the environmental impact of their operations worldwide.

Nissan Leaf EVs slip through French village to make a quiet point

Bjork's 1995 freak-out hit It's Oh So Quiet may have reflected the singer's oddball Icelandic sensibilities, but Nissan is making the concept of relative silence a French thing. The Japanese automaker recently promoted its all-electric Leaf by staging a mini-rally through what it called "one of the quietest villages in Europe." And with the exception of a couple damaged trash bins and a destroyed rear-view mirror from an old-school archway, the race kept the drivers wide awake but everyone in the Southern French village in Provence Alpes Cote d'Azur sleeping. Nissan sent four vehicles on a five-kilometer jaunt through the village in the wee morning hours. Screeching tires and a couple booms notwithstanding, the company said everyone in town stayed snoozing. There was a broader purpose to this exercise, of course, which Nissan blatantly admits was a stunt. Nissan was helping celebrate 19th Annual International Noise Awareness Day (INAD), which took place on Wednesday and highlighted the emotional and health issues as well as high blood pressure and insomnia caused by excessive exposure to noise.

NISSAN LEAF CELEBRATES INTERNATIONAL NOISE AWARENESS DAY WITH A NIGHTTIME "SILENT RIDE" ROLLE, Switzerland – To mark the 19th annual International Noise Awareness Day (INAD), Nissan has taken to the streets of one of Europe's quietest villages during the middle of the night with a silent "ride" of its 100 percent electric Nissan LEAF. The activity, complete with a start and finish line in Provence Alpes Cote d'Azur, was designed to demonstrate the noise reduction levels of the Zero Emissions car compared to traditional combustion engines. The World Health Organization (WHO) states at least 13.5 percent of Europeans are exposed to road traffic noise at levels exceeding 55 dB, which is considered detrimental to human health*. The medical effects of noise levels include insomnia (50dB), obesity (50dB), psychic disorders (60dB) and reduction in life expectancy (50dB)*. As a result, Nissan has filmed a 'silent ride' to help support INAD in raising awareness about noise pollution levels across Europe.

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.
