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.

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 invites 22-year-old to work with Red Bull F1 team

Infiniti launched the Infiniti Performance Engineering Academy (IPEA) in 2014, a global talent search for three engineering students from eleven international markets that the automaker would select for a one-year assignment with its Formula One team and road car division. The second year's IPEA competition has concluded, the class of 2015 expanding to five students that get eight months at Infiniti Red Bull Racing headquarters in Milton Keynes, and four months at the company's European Technical Center in Cranfield, UK. Twenty-two-year-old Alex Allmandinger (pictured), a student at the University of Illinois and one of 11 US finalists, is one of those five winners. He'll head to Milton Keynes next month to settle in with the other winners from China, Europe, Russia, and Saudi Arabia. Based on interviews with last year's winners, the IPEA doesn't stick the students in a corner, either – one of them said he had designed seventy parts that went into the RB11 F1 racecar. The video above speaks to some of this year's winners, the video below talks to last year's, and there's a press release below that. This content is hosted by a third party.

Aug. 20, 2015 – Infiniti has announced that an engineering student from the University of Illinois is one of five global winners of the 2015 Infiniti Performance Engineering Academy (IPEA). For one year, Infiniti will provide 22-year-old Alex Allmandinger with the opportunity to work in Formula One with the Infiniti Red Bull Racing team. After beating 11 other finalists from around the country in an intense shootout event, Allmandinger will move to Infiniti Red Bull Racing headquarters in the UK in September to begin a 12-month placement working with the four-time Formula One World Championship Infiniti Red Bull Racing team, as well as with Infiniti. Allmandinger will spend eight months working on Vehicle Design at the team's headquarters in Milton Keynes, UK – and four months working at Infiniti's European Technical Center in Cranfield – on road car development projects. Formula One technology is more relevant to the automotive industry than ever and will play a key role in the ongoing transfer of technical knowledge and expertise between the race team and Infiniti.
