North Carolina now charging $100-per-year EV road-use fee
Wed, Jan 15 2014Tobacco Road just got a little more expensive for drivers of electric vehicles such as the Nissan Leaf and Tesla Model S. This year, North Carolina started instituting an annual $100 road-use fee for electric-vehicle drivers in order to close at least a little of the budgetary shortfall for road maintenance in the Tar Heel State, the News Observer reports. North Carolina legislators failed to green-light a hybrid-vehicle fee of $50 a year, which may have made a little more of a dent in the state's road funding. As it is, about 1,600 EVs are registered in North Carolina, meaning that the state will collect about $160,000 in such fees this year. And while some in the state are concerned that the fee could hurt EV adoption, others say it's fair because of the $7,500 in federal tax credits EV buyers get. Oh, and the fact that EV drivers don't pay gasoline taxes. Either way, the fees are a proverbial drop in the bucket, as North Carolina's transportation shortfall is estimated to average about $2 billion a year during the next three decades or so. Other states are starting to charge EV drivers a road-use fee as well. Last February, Washington State began instituting its own electric-vehicle fee of $100 per annum, and a number of other states are considering similar policies.

2014 Nissan Versa Note
Fri, 28 Jun 2013Incredible Value Has Trouble Winning Hearts
How important is vehicle sticker price? How imperative is fuel economy? What about passenger room and technology?
Nissan is hoping that consumers find all four objective measurements significant, because the all-new 2014 Versa Note excels in each of those areas. Not only does the five-door deliver the most competitive pricing, but it provides best-in-class combined fuel economy and best-in-class total interior volume. And the new model offers a full range of innovative technology, including available navigation and the automaker's impressive Around-View monitor to ease parking.
Infiniti's new VC-T changes the rules of small turbocharged engines
Sun, Aug 14 2016The 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.
