Infiniti QX70 S Design goes dark in the City of Light

As Infiniti continues its attempts at making inroads in the European market, it's showing off a sharper-looking version of its QX70 crossover. Much as it does in the US market, the CUV, formerly known as the FX, is adding an S Design trim.
The new trim pack adds plenty of dark chrome to the exterior of the fashion-forward QX70, with the stuff finding its way onto the grille, foglight surrounds and side grilles. While not dark chrome, the 21-inch alloys, mirror caps and roof rails are now painted black, while the headlights are smoked. Black lacquer trim, black leather and purple stitching stand out in the S Design's cabin.

2016 Infiniti QX60 facelift spied

Initially launched in 2012 as the JX35 and rebadged in the brand's new nomenclature as the QX60 in 2013, Infiniti's three-row crossover is due for a facelift next year. And that's just what you're looking at here in this latest gallery of spy shots. Captured while undergoing testing here in the United States, the 2016 Infiniti QX60 is slated to benefit from revised styling front and rear. That means a new grille and headlights stylistically drawn from those on the QX50 and QX80, as well as a reshaped rear end with new taillights. The design changes ought to help further differentiate the QX60 from its more commonplace counterpart, the Nissan Pathfinder, on which it is based. Nissan dealers, after all, charge a good $13k less for their version than Infiniti dealers get for theirs, and customers want their premium wheels to look the part. And in the process, the updates aim to help the QX60 compete with rivals like the Acura MDX and Buick Enclave. A fresh set of wheels is almost a foregone conclusion whenever an automaker is trying to spruce up one of its models. And we can expect some updated equipment and revised materials inside as well. We wouldn't expect much in the way of mechanical upgrades under the hood. Infiniti recently recalibrated the continuously variable transmission for improved performance and refinement for 2015. Sources point towards an unveiling before year's end – which likely means the upcoming Los Angeles Auto Show later this month – before sales commence early in the new year.

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.
