Nissan Juke to get higher-performance Nismo RC model

It's hard to find more giggles for your crossover dollar than the Juke - regardless of how you feel about the way it looks, the singularly styled nichemobile from Nissan is very entertaining to drive. Yet we've always felt that the platform had more in it, and evidently its Japanese parent agrees, having recently bracketed the googly-eyed turbocharged CUV with a new Nismo model and the barking mad built-to-order Juke R. At present, neither the Juke Nismo or the GT-R-powered Juke R are sold in North America, but the former has already been confirmed for sale here.
Even when it does reach our shores, there will still be a heck of a lot of whitespace between the mild performance upgrades of the standard Nismo and the half-mill R model, and to hear the UK's Car tell it, Nissan has plans to plug that gap, too. According to its report, the automaker will shortly offer a Juke Nismo RC that will have roughly 20 horsepower more than the basic Nismo (which itself has 197 hp, nine more than the base Juke). The RC will apparently feature a lower, stiffer suspension, upgraded brakes and a unique exhaust and intake for a snarlier soundtrack. Both front-and all-wheel drive models are planned, as are manual and CVT transmission choices.
No word yet on the RC's pricing or even North American availability, but the regular-strength Juke Nismo is expected to arrive shortly, and Nissan is also said to have big plans for its performance nameplate, so we wouldn't rule it out.

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.

Recharge Wrap-up: first Chevy Volt hits 200K miles, DriveNow launches in London with BMW i3 on deck

The first Chevrolet Volt has driven over 200,000 miles. According to the owner, Erick Belmer, the car, which he purchased on March 28, 2012, is "holding up flawlessly" with "no noticeable battery capacity loss." Belmer has a commute of about 220 miles per day, rotates his tires every 10,000 miles, and gets an oil change every 38,000 miles. Belmer still loves driving his "dream car" every day, and says it is "wonderfully engineered." Read more at Inside EVs. DriveNow has launched in London, and will include the BMW i3 as part of its carsharing fleet. Daimler shut down its Car2go operations there just six months ago. Currently, DriveNow members have access to the BMW 1 Series and Mini Countryman, but come spring of 2015, DriveNow, which is a joint venture between BMW and Sixt SE, will add 30 all-electric i3 EVs to its London service. DriveNow's rates for London are set at 39 pence per minute, with an hourly maximum cost of GBP20 (about 61 US cents and $31, respectively). The service currently operates in the boroughs of Islington, Haringey and Hackney, with hopes of expanded service in the near future. Read more at Hybrid Cars or at Reuters. FIA's Formula E electric racing championship series received the Autosport award for Pioneering and Innovation. The award ceremony was a black-tie event at the Grosvenor House Hotel in London. Formula E CEO Alejandro Agag accepted the award. "Many people in motorsport, when we started Formula E, didn't think we would make the first race," says Agag. "To announce we were doing a championship with cars that didn't then exist was a real challenge. But after that first race in Beijing, everything worked." Read more at Formula E's website. The Nissan Leaf has driven over a billion collective kilometers. That's more than 621.3 million miles. Nissan said in August that it expected to reach that mark by January, and it has done just that. To celebrate, Nissan Europe has created a video to thank its 147,000 Leaf drivers to bring the car to that substantial milestone in less than four years. Check out the video below.
