2014 Nissan Altima gets updated equipment, prices

The fifth-generation Nissan Altima is heading into its second year, and to mark the occasion, it's getting updated pricing, some visual and tactile enhancements and new option packages. First up are the physical changes: All 2014 Altima models will have chrome exhaust tips, revised seat cloth (when not fitted with leather) and better noise isolation. Check the option box for the new Sport Value Package, and the Altima also will come equipped with 16-inch aluminum alloy wheels, a rear spoiler and remote engine start.
But those aren't the most important updates for 2014. Nissan is showcasing the expanded functionality of its NissanConnect system, which works with Android and iPhone handsets. Applications will be introduced in the fall and launch with Google search and Facebook, later to be joined by iHeartRadio and Pandora. NissanConnect with navigation system (separate from NissanConnect applications) will be capable of running SiriusXM Travel Link for data including weather, fuel prices and movie times. In addition, there are changes to other option groups, including a revised Technology Package and a new Display Audio Package, the specifics of which can be found in the official release.
As for pricing, the changes are pretty minimal, with the base 2.5 CVT starting at $21,860 and the full-boat 3.5 SL CVT topping out at $30,660 before options and a $790 destination fee. You can compare those figures with 2013 pricing here, and see the full rundown of all the trim level prices by scrolling below.

2013 Nissan e-NV200 taxi will carry Catalunians quietly beginning next year

The Nissan e-NV200, currently in the final phases of testing with FedEx fleets in various countries, will be getting more demanding cargo next year in Barcelona when it goes into service as a taxi. Unveiled at the Frankfurt Motor Show by Carlos Ghosn and with the mayor of Barcelona, Xavier Trias, in attendance, the e-NV200 is the van slightly reworked into a unique design and resting on a Leaf electric powertrain.
The NV200 van is built in Barcelona, and when the electric version goes into production there next year it will begin its public beta will as part of a set of initiatives the Spanish city has for zero-emissions transportation. Nissan will be helping with the build-out of infrastructure such as charging stations, while the city elders get to work on allocating privileges and special spaces for the e-NV200 taxi drivers.
After the Catalonian debut Nissan says the electric hauler will make its way to other parts of the world. Nothing's been said yet about whether it will join our combustion-engined NV200 taxis in New York. You can take a look at the fare-driven future in the high-res gallery above, and read more about it in the press release below.

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.
