Production Infiniti QX30 coming to LA Auto Show

Infiniti showed its QX30 small crossover in concept form at this year's Geneva Motor Show, and now, we've got confirmation that the production car will debut in Los Angeles. But this is just one of some 30 global reveals that will take place at the LA Auto Show this November. The QX30 will be a higher-riding version of the new Q30 hatchback that we'll see in Frankfurt later this month. And since the Q30 shares a lot of its underpinnings with the Mercedes-Benz A-Class, we can probably expect the QX30 to be a sort of Infinitized GLA-Class. Just picture a lifted version of the production Q30 we've already seen in teaser shots. In addition to 30 global debuts, the LA Auto Show will host 20 North American reveals, including the Jaguar F-Pace, Kia Sportage, and Bentley Bentayga that will initially be shown in Frankfurt. The only other LA show global reveal we know about right now is the 2016 Hyundai Elantra. Still, there will no doubt be a lot to talk about come November, with Alfa Romeo, BMW, Bentley, Fiat, Ford, General Motors, Honda, Jaguar Land Rover, Mazda, Mercedes-Benz, Mini, Mitsubishi, Nissan, Porsche, Subaru, and Volkswagen all confirming that they'll have something to show in Los Angeles. Naturally, we'll be on site with our usual obsessive auto show coverage.

Almost every manufacturer will be making news, and while most have yet to announce details, a few manufacturers have begun to share their debut plans. Specifically, Infiniti will have a global reveal of its all-new QX30 crossover and Hyundai will host the world premiere of its all-new Elantra. Other debuts include Jaguar's first luxury SUV, the F-PACE, and Kia's next generation Sportage. Other automakers officially confirming premieres include Alfa Romeo, BMW, Bentley, Fiat, Ford Motor Company, General Motors, Honda, Jaguar Land Rover, Mazda, Mercedes-Benz, MINI, Mitsubishi, Nissan, Porsche, Subaru and Volkswagen.

Next Infiniti FX to gain interior volume

The Infiniti FX, soon to be renamed QX70 thanks to the Japanese brand's convoluted naming scheme, is currently in the midst of its second-generation. And while we like the compact, sporty crossover's driving character a lot, it lacks the "utility" part of the CUV moniker. That lack of cabin space will be addressed in the future, though.
Automotive News recently sat down with Nissan's global design boss, Shiro Nakamura, to talk about the future of what he called "the icon of Infiniti." And while Nakamura-san admitted the FX/QX70's worth to the brand, its sales have long been something of a disappointment. "Exterior and styling-wise, it's very strong as an icon. But to be honest, its sales volume has not been as big as we wanted," a reality Nakamura believes is due largely to its tight cabin relative to its competition.
Finding the right balance might be difficult, though. The FX/QX70 is selling extremely well in both China and Russia, according to Nakamura, because of its looks. Altering that style in order to increase interior space risks alienating a new and important group of buyers for Infiniti. The designer put it best when he told AN, " It is selling well in China and Russia because it stands out. So we want to maintain that striking look." As it stands, we'll likely be living with the current vehicle for a few more years - AN doesn't expect the third-generation of the FX/QX70 to arrive until 2015 or 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.
