Carlos Ghosn coup theory grows: Did Nissan set him up for a fall?

'What is fascinating about this story is the politics of it'

Recharge Wrap-up: BMW Next 100 video, how Nissan "tops off" battery

BMW explains the ideas behind its Vision Next 100 concept car that debuted at the Geneva Motor Show. As BMW celebrates its 100th birthday, it wants to look into the future rather than dwell on its past. This involves the digital and analog worlds working together "to create a seamless experience." Hence the "live geometry," wherein physical parts of the car move to translate digital information to the driver. The video also gets into the future of driving modes, like "Ease," for more autonomous driving, and "Boost," for when the driver wants to take control to enjoy some motoring the good, old-fashioned way. Check out the video above, and read more from Hybrid Cars. Nissan has managed to find a way to boost the range of EV batteries inspired by pouring a glass of beer. The automaker has found that after a full charge, one can wait a few minutes for subsequent "minicharges" to "top off" the battery. The voltage dips slightly, much as the foam does on a pint of beer, allowing the battery to accept some more juice. The result is an extra 0.7 percent of energy, which could mean just enough extra range to reach the next charging station. Read more from Automotive News. Hyundai has delivered its first Tucson Fuel Cell in Ontario, Canada. The lucky recipient is Joseph Cargnelli, Chief Technology Officer of Hydrogenics Corporation, a company based on hydrogen technology. The expansion into Ontario follows Hyundai's trial of six Tucson Fuel Cell vehicles in the Canadian province of British Columbia. Read more at Green Car Congress. Toyota has entered a public-private partnership to test an end-to-end hydrogen supply chain in Japan. The collaboration with the Kanagawa Prefectural Government, the municipal governments of the cities of Yokohama and Kawasaki and three private companies to create renewable hydrogen to power forklifts. It will use wind energy to electrolyze hydrogen, which will then be shipped to a factory, a vegetable and fruit market and two warehouses to be used in the fuel cell-powered vehicles. This supply chain is expected to reduce CO2 emissions by 80 percent compared to traditionally fueled forklifts. Read more from Toyota.

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.
