Infiniti names former BMW man Kruger to fill de Nysschen role

Today is turning into a big one for senior leadership changes in the automotive industry. Hot on the heels of Ferrari announcing the replacement of its chairman, Infiniti has announced the appointment of its new chief executive in Roland Krüger.
Serving until now as a senior vice president at BMW, Krüger joins Infiniti as its president as well as senior VP at parent company Nissan, reporting directly to Carlos Ghosn. Krüger had been with BMW since 1998, primarily as a regional director, having previously started his career as a designer for Mitsubishi and the Smart division at Daimler.
Krüger's appointment comes just over a week after the announcement that Infiniti's chairman Andy Palmer would be leaving for Aston Martin, and two months after the departure of outgoing Infiniti president Johan de Nysschen for Cadillac. The Japanese luxury automaker, headquartered in Hong Kong, has been in the meantime essentially operating by committee in the absence of a chief executive. The nomination of Krüger will surely bring a large measure of stability and direction as the company seeks to take a larger slice of the pie, in particular from German automakers like the one for which Krüger worked until now.

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.
