Recharge Wrap-up: Nissan Leaf in Puerto Rico, BMW i3 REx tax-free in NJ, BC2BC cancelled [UPDATE]

*UPDATE: Nissan has released a video of the Leaf in Puerto Rico, so we've embedded it below. Envia Systems will develop battery technology for United States Advanced Battery Consortium (USABC), a subsidiary of the United States Council for Automotive Research (USCAR). The $7.7 million contract, co-funded by the US Department of Energy (DOE), involves a 36-month development program focusing on high-energy cathode and anode material for lithium-ion batteries and pouch cells for electric vehicles. The goal, of course, is to create better energy storage for less money in an effort to make commercial EVs more efficient and affordable. For the DOE, this also equates to energy security, energy independence and national security. Read more in the press release at the bottom of the page. The US and China have agreed to work together more closely on EVs, energy and climate issues. US Secretary of Energy Ernest Moniz went to Beijing for the sixth US-China Strategic and Economic Dialogue to meet with leaders. While there, Moniz and Wu Xinxiong of China's National Energy Administration (NEA) signed a memorandum of understanding allowing the DOE and NEA to share information regarding oil reserves. The groups will meet yearly to learn more about how each other manages petroleum stockpiles and policy. Moniz also met with Minister Miao Wei of the Chinese Ministry of Industry and Information Technology and signed an MOU to cooperate on electric vehicles and "related technologies," including the "inter-operability of electric vehicles."

The event, which was to include a drive up the entire coast from Mexico to British Columbia with smaller events along the route, failed to bring in the needed sponsorship to hold the rally for its third year. A Facebook post from organizer Tony Williams also cited loss of venue and lack of support from automakers - "particularly Nissan and Tesla" - as hardships. The event was scheduled to take place August 9 through 17, with only battery electric vehicles invited to take part - no plug-in hybrids or range-extended vehicles. Williams said he'd only try a similar event in the future if sponsorship were provided up front. Read more at Green Car Reports. The Nissan Leaf will finally go on sale in Puerto Rico.

Nissan recalling more than 1M vehicles for airbags that may fail to deploy

Nissan and the National Highway Traffic Safety Administration have issued a recall for 989,701 vehicles in the US due to an issue with their passenger-side airbag systems. Affected Nissan models include the Altima, Leaf, Pathfinder and Sentra from the 2013 and 2014 model years, and 2013 NV200 taxis. Affected Infiniti models include the 2013 JX35 and 2014 Q50 and QX60 utility vehicles.
Reuters is reporting that a total of 1,053,479 vehicles are included in the recall globally, with about 60,000 of the affected vehicles having been sold in Canada.
The fault apparently lies in something called the occupant classification system, which may, in the recalled vehicles, incorrectly classify the passenger seat as empty when it is in fact occupied by an adult. When the system fails to recognize the passenger, the passenger-side airbag may deactivate, and could therefore fail to deploy in the event of a crash.

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.
