Watch this 800-hp Nissan Juke-R savage the 'Ring

The concept of the 545-horsepower Nissan Juke-R that stuffs the drivetrain of a GT-R into a subcompact crossover is already insane, but Russian company Shpilli Villi Engineering has taken things even further with their own crazy riff on the idea. Its version tunes the engine up to a claimed 800 horsepower, plus a shot of nitrous for an extra 200 hp to put it (way) over the top. Naturally, a number of other upgrades have been exacted in an effort to try and keep the custom Juke's shiny side up and the driveline internals from spontaneously rearranging themselves. Those changes include a beefed-up switchable all-wheel drive or rear-wheel drive layout and revised suspension.
Last year, you may recall that we saw an earlier version of Shpilli Villi Engineering's insanity testing with a mere 700 hp in a one-mile, standing drag race against a Bugatti Veyron. In that state of tune, the Juke-R lost, but by less than a hundredth of a second. Now, owner and racer Vladimir Ulanov has brought his madness to the Nürburgring Nordschleife to see how it does around a damp lap of the famous track.
It looks like 800 hp and a moist track might be almost too much for this Juke to handle, because Ulanov gets very loose at several points during the lap. Understandably, his passenger seems suitably impressed and possibly a little freaked out at the end. See what you think of this craziness by watching the video.

Recharge Wrap-up: Nissan 'No Charge' in Denver, A123 doubles

Nissan has introduced its "No Charge To Charge" program in Denver, Colorado. As of June 2, customers who buy their new Nissan Leaf from certified dealers in the metro Denver area will get two years of free charging. Denver is the 16th market to offer "No Charge To Charge," with a total of at least 25 US markets scheduled to offer the program by the end of the year. "EV charging infrastructure continues to grow in Denver," says Nissan EV Sales and Marketing Director Andrew Speaker, "and access to free public charging for new Leaf buyers helps make owning an all-electric vehicle even more cost-effective and convenient."

The combined capacity of its three production facilities in Michigan, Hangzhou, China and Changzhou, China will increase from 750 megawatt-hours to 1.5 gigawatt-hours in the next three years. The increased capacity will help support customers building hybrids, passenger EVs, and commercial vehicles. Included in the expansion is the capacity to build 12-volt starter batteries and 48-volt microhybrid systems. "It's been a tremendous turnaround," says A123 CEO Jason Forcier, referring to the company's 2012 bankruptcy. Forcier also says the company is already planning another expansion when this one is complete. Read more at Automotive News, and in the press release from A123. The Royal Hashemite Court of Jordan is ordering 150 Zoe EVs from Renault. King Abdullah II of Jordan signed an agreement with Renault, who will deliver the cars by the end of the year. The cars will be powered completely by solar energy generated on royal property. The order of the 150 Zoes is the largest since 2013, and makes Renault the largest provider for Jordan's royal EV fleet. Renault says that further EV orders are already being discussed.

Current policy, designed to help alleviate traffic and air pollution, restricts cars with even and odd license plates from rush hour traffic on alternating days. The exemption for EVs runs from June 1, 2015 until April 10, 2016. It is the newest in the list of perks meant to encourage EV adoption, despite the troublesome lack of charging infrastructure.

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.
