A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

Nissan to present Vision Gran Turismo concept at Goodwood?

Power up your PlayStation and pop in any edition of Gran Turismo and you'll have hundreds of cars to choose from. But arguably few have managed to bridge the gap between that virtual world and reality than Nissan.
The Japanese automaker is the one responsible for putting the best gamers behind the wheel of actual race cars with its GT Academy, co-sponsored by Nissan and Gran Turismo. Yet while the likes of Mercedes-Benz, BMW, Volkswagen and Mitsubishi have already revealed their Vision Gran Turismo concepts specifically designed for the game, Nissan has been left behind. And as it is apt to point out in its latest infographic, that's not a position to which it's accustomed.
The graphic outlines all 148 Nissan vehicles you can drive in Gran Turismo, but leaves the last one under wraps, identified only by the date June 10, 2014. That's this Tuesday, when Nissan is hotly anticipated (thanks in no small part to the Tweet below from Nissan VP Andy Palmer) to reveal its own Vision Gran Turismo concept at the Goodwood Festival of Speed.

The art of racing the Nissan GT-R

There's no question that the Nissan GT-R is one of the very fastest cars that money can buy, and that its sophisticated all-wheel-drive system and active suspension give its drivers an absurd level of control at speed. In fact, the GT-R's technical brilliance and video-game quickness often spur armchair critics to make absurd claims that kind of amount to: "The car basically drives itself."
Having a bit of fun with those particularly salty members of the peanut gallery, YouTube producers at That Racing Channel have put together an instructional video about the finer points of GT-R driving and street racing. Scroll down below to get an idea about just how difficult Godzilla can be to keep hold of at the limit.
