Infiniti QX30 Concept is... a mountain lion that stings?

According to Alfonso Albaisa, Executive Design Director at Infiniti, "The Q30 Concept was like a panther, lithe and slender. We transformed the QX30 Concept into a mountain lion, strong and muscular." He added, "With its higher stance and edgier design to match its tough capabilities, you can almost visualize how the QX30 Concept floats like a butterfly and stings like a bee." We're not quite sure that it looks like a mountain lion or whether it buzzes and stings, but it's definitely more aggressive than the Q30 Concept that it shares a good deal of underlying structure with, and that seems appropriate. We also think it stands apart as different than the cars it will compete against, like the Audi Q3, BMW X1, Mercedes-Benz GLA, Lexus NX and Buick Encore, which is a good thing, considering that those models have a solid head-start in the burgeoning premium compact crossover segment in which the QX30 will play. Power in this conceptual crossover comes from a 2.0-liter, turbocharged four-cylinder, and a seven-speed automatic transmission sends power to all four wheels, but Infiniti is quick to say that the QX30 will boast "a wide range of powertrains," so perhaps a hybrid or diesel could join the fray in some markets. We'll have to wait and see, but Infiniti says the QX30 is "earmarked for production" in 2016.

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 recalling GT-R, Infiniti crossovers over steering column issue

Nissan has discovered a problem with the steering column on some of its higher-end all-wheel-drive vehicles from a few years back, and has issued a recall in conjunction with the National Highway Traffic Safety Administration to address the issue. The issue revolves around the outer tube on the steering column, which may not be perfectly round. That would put extra stress on the upper steering bearing, which could cause it to fracture, disabling the car's steering ability and potentially leading to a crash. The problem affects Nissan's flagship GT-R supercar – specifically 2009 models manufactured between March 14, 2007, and April 25, 2008) as well as an array of Infiniti crossovers: namely the 2008 EX35 and the 2008-09 FX35 and FX45. In the case of the luxury crossovers, Infiniti dealers are being instructed to replace just the steering shaft, but Nissan dealers will have to replace the entire steering column assembly on the GT-R. All told, the recall is estimated to encompass 16,973 vehicles across the United States. RECALL Subject : Steering Column Tube may be Out of Round Report Receipt Date: FEB 02, 2015 NHTSA Campaign Number: 15V054000 Component(s): STEERING Potential Number of Units Affected: 16,973 Manufacturer: Nissan North America, Inc. SUMMARY: Nissan North America, Inc. (Nissan) is recalling certain model year 2008 Infiniti EX35 vehicles manufactured June 29, 2007, to April 25, 2008, 2009 Infiniti FX35 and FX45 vehicles manufactured October 31, 2007, to April 16, 2008, and 2009 Nissan GT-R vehicles manufactured March 14, 2007, to April 25, 2008. The steering column outer tube may not be round, resulting in extra stress being applied to the upper steering bearing. This stress may cause the bearing retainer to fracture, creating extra play in the steering wheel or a possible loss of steering. CONSEQUENCE: Extra play in the steering wheel or a loss of steering may increase the risk of a crash. REMEDY: Nissan will notify owners, and dealers will replace the steering shaft on the Infiniti EX35, FX35, and FX45 vehicles, and will replace the steering column assembly on the Nissan GT-R vehicles, free of charge. The manufacturer has not yet provided a notification schedule. Infiniti owners may contact customer service at 1-800-662-6200. Nissan owners may contact the GT-R hotline at 1-866-668-1487.
