Prince Charles tours Nissan Leaf plant in Sunderland, UK

Environmental sustainability and job training. Those are two of the issues the UK's Prince Charles, the Prince of Wales, has long supported. And that's why the king-to-be paid a visit to Nissan's Sunderland plant earlier this week. As shows in a two-minute video from Broadcast Exchange, Prince Charles took a tour of the plant, checking out the production line while conferring with the young (and slightly star-struck) students there who were learning a thing or two about building a car, electric Nissan style. The Sunderland plant is located about 285 miles north of London. The factory runs an apprenticeship program for budding car-builders and employs about 6,700 people. The Nissan Leaf electric vehicles built there are sold in Europe, where Leaf sales jumped 33 percent last year. Opened in 1986, the Sunderland factory broke ground on its battery-production facilities in 2010 and began producing the Leaf in the spring of 2013 after Nissan invested about $635 million upgrading the plant to handle electric-vehicle and lithium-ion battery production. Even before the EV battery production activity the Sunderland plant burnished its green credentials by installing wind turbines to help with the power supply. Prince Charles already has his credentials (sort of), thanks to a biofuel Jaguar and a wine-powered Aston Martin. Check out the video with Prince Charles below.

Datsun reveals new On-Do budget sedan in Russia [w/video]

When Nissan revived the Datsun brand name, it essentially hit the "undo" button on the rebranding it undertook decades ago. But this time, the Datsun name is being used solely as a budget brand for developing markets. The reborn marque launched in India this past July with its Go hatchback, returned in September with the Go+ minivan and revealed the Redi-Go concept just last month. And now it's back again with the new On-Do sedan.
Launched in Moscow by CEO Carlos Ghosn, the On-Do was designed and engineered in Japan specifically for the Russian market - Nissan's fifth largest worldwide - where it will be built at the AvtoVaz plant in Togliatti. Decidedly budget-oriented, the Datsun On-Do is a four-door, five-seat econo-box measuring 172 inches long, 67 inches wide and 60 inches tall with an 18.7 cubic-foot trunk which Datsun describes as class-leading. Punctuating an otherwise bland shape is a large front grille and lighting front and rear that looks (and very well might be) bigger than the wheels.
Not that the Datsun On-Do needs a big contact patch to transfer power to the road: motivation is provided by a 1.6-liter engine with a grand total of - wait for it... wait a little longer - 87 horsepower. Which might strike you as a reasonable amount of muscle, considering the 400,000 rubles Datsun is getting for the On-Do (but consider that translates to about $11,300). That's a couple grand more than what Nissan gets for the Micra in that other giant northern country, or about the same amount it gets for the Versa in the US (which sells in Russia for 499k in rubles) - both of which are powered by what is in all likelihood the same 1.6-liter four but producing 109 hp. Of course Russia has different tax rates than the United States or Canada, but with such little power, the Datsun would fall into Russia's lowest tax bracket.

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.
