Nissan NV200 finds new work as ambulance, Gibson guitar repair truck

We live in a world now where not every police cruiser and taxi is a Ford Crown Victoria, not every executive car is a Lincoln Town Car and not every ambulance is based on a Ford Econoline van. Vehicles like the new Nissan NV200 are making inroads into the service, livery and emergency vehicle markets, and we've got a couple cases in point to share.
The first one is a fleet of 30 new ambulances based on the heavier-duty NV2500 chassis. They are entering the Mexican Red Cross fleet of emergency vehicles this year after performing well in pilot tests last year. The Mexican Red Cross says it receives 1,200,000 ambulance service requests per year, so the mettle of these new machines will be tested in a hurry.
The second example is less useful for life-saving, but may save a guitar from going to the scrap heap. Called the Gibson NV200 Mobile Repair & Restoration Van, it can take the services of an authorized Gibson rep anywhere they're needed to repair or restore an axe in need. The van features a whole aesthetic designed to evoke the classic Gibson look, with wood veneer and shades of brown and black used throughout. There's a guitar rack that holds four instruments, a sliding 56-inch long repair table, toolbox, genuine Gibson stools and a sound system by Gibson Pro Audio.

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.

Nissan's current Rogue renamed Rogue Select, will live alongside next gen

Despite the fact that an all-new generation of its Rogue crossover goes on sale in November, Nissan will continue to sell the current model alongside its replacement. The existing C-platform-based Rogue, which will be renamed Rogue Select, will start at less than $20,000 when it goes on sale in January 2014. At present, a base 2013 Rogue S prices out slightly higher, from $20,310, but we wouldn't be surprised to see the 2014 Rogue Select come to market with more standard equipment and simplified trim options. It will continue to be built in Kyushu, Japan.
According to Nissan, the unusual move is "to satisfy demand for the popular compact sports utility vehicle, currently second-highest seller in Nissan's lineup, as well as provide customers an additional choice in the segment." It's hard to hard to argue with the numbers: Nissan cites 2012 calendar-year sales of 142,349 Rogue units in the US, with 2013 sales increasing 16 percent through August despite the vehicle's age.
The strategy may also give Nissan the chance to ask for more money for the second-generation model (which is based on a new Common Module Family platform shared with partner Renault) while keeping it clear of residual-value-damaging fleet sales. The new Rogue looks to be both larger and more luxurious, with an available third-row seat, and it should be more economical to produce, as it will be built in Nissan's Smyrna, TN plant.
