Nissan Concept 2020 Vision Gran Turismo looks awesome in red

As we reported the other day, Nissan has a whole raft of concepts it's bringing to the Tokyo Motor Show this year, but the Concept 2020 Vision Gran Turismo is perhaps the most striking. Or at the most least colorful. Now if you're thinking that we've already seen Nissan's concept for the popular racing sim, you're absolutely right. It debuted last summer ahead of the 2014 Goodwood Festival of Speed. But sinister as it looked in gray, this time it's been done up in bright red – Fire Knight red – according to the automaker. And as you can see for yourself in the gallery above, it looks awesome. Of course the Teatro for Dayz is still the main novelty here. Envisioned as a theater on wheels (hence the name), the Teatro packs the company's electric powertrain technology that we've already come to know from the Leaf. The interior is all smooth and white, serving as a sort of blank canvas of sorts – ostensibly allowing for a broad range of personalization. The minicar could point the way towards a successor to the equally quirky Cube that has, in its present iteration, been on the market since 2008. Or it could just be a showpiece for its home-market show, which only comes around every other year. Either way, you can check it out in the second image gallery. While you're doing that, we'll be staring at that red supercar concept for a while longer, and wondering how closely it might presage the next-generation GT-R. Nissan to show Teatro for Dayz, Gripz, Concept 2020 Vision Gran Turismo and more in Tokyo YOKOHAMA, Japan – Nissan Motor Co., Ltd. today released an overview of its exhibit at the 44th Tokyo Motor Show, which will be held at Tokyo Big Sight and open to the public from October 30 through November 8. Among the exhibits will be Teatro for Dayz, an innovative concept that signals a new direction in mobile technology. Designed especially for the digital native generation, this vision of near-future vehicles departs from convention and marks a shift in perception.

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.
