2013 Nissan Pathfinder: January 2013

We've now had our long-term 2013 Nissan Pathfinder for about a month, and some impressions are starting to solidify, while others remain contentious among the team. Most notable among those contentious items is our Pathfinder's paint color, which was chosen by vote among the Autoblog team.
Dubbed Mocha Stone, it beat out Cayenne Red by a single vote. I was a Mocha Stone supporter and like it even more in person than on Nissan's configurator. It's a mature choice that can be comfortably placed in the grouping of silver, white and gray tones buyers routinely choose most often over all the colors of the rainbow offered on cars these days for the sake of attention. Staunch opponents of Mocha Stone on the team remain unswayed. Democracy is a difficult process, people.

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 exec talks about smaller Leaf, and maybe a CUV EV as well

The Renault Zoe is a popular electric vehicle in Europe, and it gives buyers on the continent a zero-emissions option that's smaller than the Nissan Leaf. Here in the US, Nissan only offers its one all-electric passenger vehicle, but the company might be taking a page from its corporate partner to offer a smaller Leaf in the near future. According to Gareth Dunsmore, Nissan EV European head, Nissan is thinking about both a smaller EV based on the Zoe and larger, all-electric SUV/CUV. "We've invested $5.4 billion in electric cars such as the Leaf, so we need to ensure we're satisfying as many types of customer as possible," he said. "In Europe, that could mean looking towards B-segment hatches and SUVs or crossovers," according to Auto Express. "If we look towards crossovers or the B-segment for the next car, those could make perfect sense." As for what we actually know about the next-gen Leaf, details are scarce. We did get confirmation that a 200-mile range update is in the works, but information on timing and other details are still something we're waiting for. Let's throw the idea of a smaller Leaf into the rumormill and see when Nissan starts talking. The gallery above shows off the Nissan IDS concept, which was shown at the Tokyo Motor Show last year.
