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.

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.

Recharge Wrap-up: Infiniti considers EV for China, NextEV hires former Tesla, Apple engineer

NextEV has hired Tesla Autopilot and Apple veteran Jamie Carlson as Senior Director of Advanced Technologies. The seasoned autonomous driving engineer joins fellow former Autopilot engineer Kurt Thywissen, who is now NextEV Senior Director of Human-Machine Interaction. NextEV, which is working on an all-electric supercar before focusing on mainstream EVs, recently obtained a self-driving car permit from California and opened its North American headquarters in San Jose. Read more at Electrek. Infiniti is considering launching its first EV in China. "When I think about EV, we design it for China definitely, even as the first market to launch," says Infiniti President Roland Krueger. "We are discussing this internally constantly what is the right timing for Infiniti to have such vehicles." Infiniti has held back on launching an EV, focusing instead on hybrids, but says it could be "very fast" in deploying an EV once it decides to do so. Having Nissan and Renault backing Infiniti, the luxury brand is confident about its access to proven EV technology. Read more at Automotive News Europe. Thrifty car rental has added a Tesla Model S to its fleet in Canberra, Australia. Available at the Canberra Airport, it's the first luxury EV offered for rent from a mainstream rental company in Australia. Australia's capital offers a small registration discount and no stamp duty for EVs, making it a cheaper and more practical place to locate the country's first rental Tesla. Thrifty's parent company, NRMA, is calling on Australia's other states and territories to remove financial and regulatory barriers to EV technology. Read more at The Motor Report.
