Recharge Wrap-up: Renault-Nissan at COP21, fast charging viability

Nissan and Renault's combined fleet of 200 EVs drove over 175,000 kilometers (about 108,700 miles) during the COP21 environmental summit in Paris. The largest fleet of EVs for any international conference served as shuttles for attendees, saving almost 182 barrels of oil and 18 tons of CO2 emissions. In addition to providing the Nissan Leaf, Nissan e-NV200, and Renault Zoe EV shuttles, the Renault-Nissan Alliance also set up a network of 90 chargers to support the fleet. 13 of the 27 quick and semi-quick chargers will remain in place for public use.

The company will implement new and upgrade existing traffic technologies in the city, including cloud-based traffic management software, local controller software and an adaptive traffic control system designed to improve traffic flow and safety. In a college town with highly varying numbers of students and visitors throughout the year, "the need to move traffic in and out of the city efficiently is crucial not only for economic and environmental impacts, but for quality of life for Ann Arbor residents," says Marcus Welz, president of Siemens Intelligent Traffic Systems. Many Ann Arborites (your author included) would surely agree.

The researchers found parking spots to be the most popular public charging locations, and that fast chargers saw the most frequent use, suggesting commercial viability for the infrastructure in the short- to medium-term. The study also found that most drivers prefer to charge at home, and do so during peak hours. Incentivization could be necessary to break people from this habit. Read more at Green Car Congress.

Ken Block's Gymkhana 8 to feature Dubai Police cars?

Yesterday we showed you the shiny Ford Fiesta that Ken Block will slide, spin, and hoon through the next Gymkhana video. In case the image above isn't clear, that video will drop at midnight EST on February 30th on the Ford Performance YouTube channel. We don't know all the entire premise of the video yet, but this Tweet from the man himself reveals that the video will be set in Dubai. Block is standing on the Fiesta we saw yesterday, and arrayed behind him are a handful of those famous Dubai Police cars you're probably familiar with. The force has a fleet of sportscars and supercars, and the purpose is outreach and goodwill among its citizenry, not necessarily the pursuit of criminals. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. From left to right, we can see a Maserati GranTurismo, Porsche 911, what looks to be a Nissan GT-R obscured by Block's Fiesta, a McLaren (likely a 650S), Ford Mustang, and a Ferrari 599 of some ilk. Will they take part? Maybe Block will try and run from what might be the most horsepower-intensive police fleet in the world. We'll have answers (and a few minutes of pure Block hooniganism) in a few days. Related Video:

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.
