Infiniti moves to trademark Eau Rouge

With Formula One taking to Belgium and the famous Spa-Francorchamps circuit this weekend - boasting a reputation as one of the most beautiful courses on the calendar - all eyes will likely be on the tricky Eau Rouge corner, which challenges drivers' high-speed car control over a rolling, tree-lined hill. Infiniti played on the turn's iconic legacy for its ruby red Q50 Eau Rouge concept, and now the brand hopes to trademark the famous racing name so it can keep using it for a potential production version.
In January, the company filed for a trademark on Eau Rouge for "Automobiles and their structural parts; Fuel cell automobiles and their structural parts; Concept cars" with the US Patent and Trademark Office. According to Bloomberg, the application is still under consideration and not yet a guarantee. It's possible that the track could attempt to block the automaker from earning rights to the name. Alternatively, a trademark lawyer tells Bloomberg that the two of them could also strike a deal where Infiniti would pay a small amount for each car sold bearing the title, which could give Spa a bit of extra money in the bank.
Regardless of the name, a vehicle like the Eau Rouge is something enthusiasts have been wanting for years. It combines a modified, 560-horsepower version of the engine from the Nissan GT-R into a four-door sedan covered in aggressive, carbon fiber aerodynamic parts.

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.

Daimler and Nissan to build luxury cars at new plant in Mexico

A few years back, when Daimler was looking for a partner to spread the cost of development of small cars, it agreed to collaborate with Nissan on future products, such as vehicle platforms and drivetrains. The latest development in the collaboration concerns the assembly of small luxury cars for Infiniti and Mercedes-Benz at a Nissan plant in Mexico, two unnamed sources told Reuters.
The plant in question, Aguascalientes, is a $2 billion project that will open later this year next to an existing Nissan factory. The upcoming Infiniti Q30 four-door hatchback is expected to be built there, possibly alongside the Mercedes GLA-Class, which is one of several candidates Mercedes is considering to build at this facility, Reuters reports. The GLA will debut at the Frankfurt Motor Show this month, and initial production of the model will take place in Germany. The Q30 could follow a similar path, with assembly starting at Nissan's Sunderland plant in the UK, and then expanding to Aguascalientes later on.
The underlying platform of the Q30 and GLA, codenamed New Generation Compact Car (NGCC), was developed by Daimler. The Q30 would be the first Infiniti produced under the automakers' agreement. Last year, Nissan agreed to make engines that would find their way into Mercedes and Infiniti vehicles.
