Watch Formula Drift's Chris Forsberg break in a new warehouse

Here are just a few great drift cars: Toyota AE86, Mazda RX-7, Nissan Z, Nissan Silvia, and Ford Mustang. One vehicle you won't find on that list, however, is the Infiniti M, because it's a big, heavy luxury car.
It's comfortable, spacious and better to drive than you might expect. And yet, even though it was possible to get one with a very nice 335-horsepower, 4.5-liter V8, it wouldn't be the first car we'd gut and take drifting in an empty warehouse. Formula Drift driver Chris Forsberg didn't get our memo, evidently, which is why we have this video of him flinging a big, white Infiniti through an empty building.
It's an entertaining video, if only because using an M as a drift car is just such a ludicrous sight. Scroll down to watch the entire clip.

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 Concept bows again, now with more GT-R [w/video]

Think back to the 2014 Detroit Auto Show and you'll remember the Infiniti Q50 Eau Rouge concept - a sedan that showed the potential design direction for a seriously high-performance take on the Japanese automaker's new entry-level luxury sedan. And while the show car we saw in Detroit was all well and good, it lacked something. Specifically, an engine. Kind of an important thing for a performance concept, right?
Here in Geneva, Infiniti rolled out that same Q50 Eau Rouge, but with one major modification: the sedan now boasts a twin-turbocharged 3.8-liter V6 under its hood - the same engine that's found in the Nissan GT-R supercar. In the Eau Rouge, this V6 is tuned to produce 560 horsepower and 443 pound-feet of torque, sent to the ground via the GT-R's all-wheel-drive system. Of course, this super-hot Q50 is still purely a concept, but Infiniti says that the potent engine underhood will allow the sedan to sprint to 60 miles per hour in less than four seconds, on its way to a top speed of over 180 mph.
The oft-fabled "four-door GT-R" still isn't confirmed for production, so for now, all we can do is cross our fingers (and toes). Check out the Q50 and its new beating heart in the gallery, above, and scroll below to hear what that potent Eau Rouge sounds like.
