Macron and Abe seek to avert messy Renault-Nissan breakup

TOKYO/PARIS – France and Japan's leaders met for bilateral talks to avert a diplomatic row over the Renault-Nissan-Mitsubishi alliance on Friday following the surprise arrest of its Chairman Carlos Ghosn in Japan. With the carmaking alliance facing its biggest test after the ousting of Ghosn at Nissan and affiliate Mitsubishi over financial misconduct allegations, President Emmanuel Macron sat down with Prime Minister Shinzo Abe at the G20 summit in Buenos Aires. Ghosn's arrest to face accusations including the under-reporting of income has triggered new attempts by Nissan to weaken Renault's control of the Franco-Japanese alliance, adding to challenges facing Macron at home. Macron, whose government has repeatedly pressed Japan to share evidence unearthed by Nissan's internal investigation into Ghosn, "restated his firm wish that the alliance should be preserved, along with the stability of the group," an Elysee official said after Friday's meeting with Abe. Abe said it was important to "maintain a stable relationship," according to a spokesman for the Japanese leader. "However, he said the future of the alliance is up to the private-sector shareholders. The government of Japan does not prejudge the future of the alliance," the spokesman said. The French official quoted Abe as telling Macron that "the legal process must be allowed to take its course." LEADERLESS Tokyo authorities on Friday extended Ghosn's detention for a second time, by the maximum-allowed 10 days, local media reported. Prosecutors must file charges by Dec. 10 or arrest Ghosn for new crimes to hold him beyond that date. Tokyo prosecutors declined to comment. Nissan did not immediately respond to a request for comment. Ghosn's detention has left the global auto alliance without its leader and main interlocutor with the French government, which owns 15 percent of Renault and wants to maintain the ownership structure enshrining its control of the partnership. But Nissan Chief Executive Hiroto Saikawa has made clear that Nissan wants to weaken the control of its smaller parent as it carries out a governance review. Renault's 43.4 percent Nissan stake ensures an effective voting majority at shareholder meetings, while Nissan's reciprocal 15 percent Renault holding carries no voting rights.

Recharge Wrap-up: Reverse graffiti powered by Nissan Leaf; BMW introduces Wallbox Pro

BMW has a new, faster version of the Wallbox home EV charger. The Wallbox Pro offers 7.4 kilowatts, and can charge the BMW i3 to 80 percent in under three hours. It features a seven-inch touchscreen and proximity sensor, plus an 11.5-foot cord. The Wallbox Pro can also be used with smart home systems such as lighting and heating. The Wallbox Pro is available in Europe, and will come to the US later in the year. Read more at Hybrid Cars. Nissan is using the Leaf to power the creation of "reverse graffiti" in London. The company has commissioned artist Moose to selectively wash dirt off of a wall outside of a subway station, leaving behind a mural of London landmarks. Moose used a jet washer powered by the Leaf's battery to create the piece. The goal is to highlight the amount of pollution in London and other large cities, which is not a new idea. "It is a reminder that electric vehicles don't have an exhaust to emit the kind of air pollution which has stained the wall Moose has created his piece on," says Nissan's Jean-Pierre Diernaz. See the artwork in the gallery, and read more in the press release below. Local Motors used a 3D printer to make the Strati electric car in 44 hours. The car was printed with 212 layers of carbon-reinforced ABS thermoplastic. After printing, the team then spent two days finishing the car to make it run. It is powered by the drivetrain from a Renault Twizy, and is capable of 40 miles per hour. Now the question is if this sort of small-scale car manufacturing using 3D printing technology will catch on. See how a car gets printed in the time-lapse video below, and read more over at Treehugger. Nissan cleans up London with the world's first car-powered graffiti - Nissan LEAF powers "Reverse Graffiti" street art in Waterloo - Mass-scale mural imagines a cleaner London, without car fumes - The artwork is on show in Waterloo, London near popular Southbank LONDON – Nissan is highlighting London's battle with air quality in the UK by using the 100% electric Nissan LEAF – the world's best-selling electric vehicle (EV) – to power a striking piece of street art in Waterloo, London that depicts the capital's iconic skyline. Nissan commissioned Reverse Graffiti artist Moose – the founder of his field – to create the mass-scale mural, which was unveiled today. Unlike traditional graffiti, Moose creates his art by cleaning dirt off surfaces using a jet washer or wire brush, leaving a striking design in negative on the wall.

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.
