Infiniti looking for a new boss after Christian Meunier leaves to lead Jeep

Nissan's premium division Infiniti is expected to announce a new acting global chief for the brand, the company said, after its current head, Christian Meunier, left to lead the Jeep unit of Fiat Chrysler Automobiles. Nissan's chief quality officer Christian Vandenhende will oversee Infiniti's global operations effective immediately, until a new brand chief is named, Infiniti said in the statement on Tuesday. Meunier, 51, was named Infinit's global chief in early January after its previous boss Roland Krueger left the Hong Kong-based brand. Meunier will take over as global president for SUV-focused Jeep effective immediately, Fiat Chrysler said in a separate statement. Fiat Chrysler CEO Mike Manley had been running Jeep until he was elevated to the top job in July after the death of Sergio Marchionne. Meunier has international experience from his years with Ford, Land Rover, Nissan and Infiniti, which may prove valuable as Jeep attempts to expand overseas with a lineup of new products including the Gladiator pickup, a Wrangler plug-in hybrid, and the revived Wagoneer and Grand Wagoneer nameplates. He's worked mostly in sales and marketing roles, including as senior vice president of sales, marketing and operations for Nissan North America; chairman of Nissan Canada; and his recent role heading up Infiniti. An Infiniti spokesman said Meunier's resignation was not related to Nissan's internal investigation into its former leader Carlos Ghosn.

Infiniti readies Juke-based ESQ crossover specifically for China

When most luxury automakers started getting into SUVs and crossovers, they started at with the largest models, but have gradually been getting smaller. Think Lexus and the LX, Audi and the Q7, or BMW and the X5, and you'll see what we mean, because each of them has been steadily downsizing its crossovers ever since. But Infiniti is going even smaller. At least, in China, anyway.
That's where the luxury marque from Nissan will soon be offering the new Infiniti ESQ. The smallest of Infiniti crossovers has been developed in China, exclusively for the Chinese market to meet Chinese tastes. It shares its underpinnings with the Nissan Juke, but instead of starting with the base model, Infiniti China has started with the more potent Juke Nismo - complete with 1.6-liter turbo four producing 197 horsepower - and added on premium accoutrements. The exterior that appears to be differentiated by a new grille and wheels, featuring the ESQ logo instead of Infiniti's, but the same quirky styling that sets the Juke apart. Though all we can of the interior is the steering wheel, you can bet that Infiniti gave the ESQ a more luxurious cabin space, too.
Infiniti's global communications manager Stefan Wienmann told Autoblog that the company is "expanding [its] portfolio not only globally but also specifically in China," adding the ESQ to a market-specific lineup that includes long-wheelbase versions of the Q50 sedan and QX50 crossover. "We see specific sales opportunities in this segment," explains Wienmann, adding that a targeted project like the ESQ "also enables us to gain experience in positioning a new premium model to the 'new millennials', a customer group that is very important to us."

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.
