2014 Infiniti Q50 configurator comes alive

The G37-replacing 2014 Infiniti Q50 sport sedan launches in the not-too-distant future, and for those curious about how pricing and packages will shake out, the car's official online configurator has been launched. Here, you can build the Q50 or Q50 Hybrid of your dreams, with the cost of entry starting at $36,450 (plus $905 for destination).
Selecting the hybrid model adds $7,250 to that bottom line - mostly because the gasoline-electric version is only available in the Premium trim and higher, while the gas-only Q50 comes in a base guise. Adding all-wheel drive, which Infiniti has made available with either engine and on all trims, will set you back $1,800.
There are a number of packages available across the trims, including a $1,400 navigation pack that includes a spare tire kit, a deluxe touring pack that costs $4,700 (and includes the navigation goodies), and the upper-crust $7,900 technology package which gets you, well, everything. Put that all together on a Venetian Ruby Q50 RWD Sport like we did, and you're looking at $51,755 when destination has been added.

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 Q50 Eau Rouge racing toward Detroit with Red Bull in its veins

There are several ways an automaker can get into Formula One racing. It can start its own team from scratch (like Toyota did in 2002), it can buy an existing team (like BMW did with Sauber in 2005) or it can supply engines to other teams (as so many manufacturers have done over the years). Infiniti chose another direction and opted to sponsor the world-champion Red Bull Racing team.
Infiniti has undoubtedly poured millions into its partnership with Red Bull since it started in 2011, but aside from the Sebastian Vettel edition FX (which technically emerged from the company's sponsorship of the driver as separate from the team), the tie-in has yet to translate into a Red Bull-tuned (or at least -inspired) Infiniti for the road. But that's just what Nissan's premium brand has in store for us at the upcoming Detroit Auto Show in January.
Well, almost, because the concept just announced is still a step or two away from reaching your local Infiniti dealership, but here it is just the same. It's called the Q50 Eau Rouge, and it's based on the company's latest tech-laden sports sedan. It takes its name, of course, from the famous uphill section of the Spa-Francorchamps circuit where Sebastian Vettel won the Belgian Grand Prix earlier this year, but Infiniti isn't telling us much more than that.
