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.

Watch a Nissan GT-R run Le Mans in 360-degree video

If you aren't reading this post on your iOS or Android device, or in the Chrome web browser, you're going to want to switch formats. That's because the video above is shot in an interactive, 360-degree format, and it only works on the YouTube app or in Chrome. Got that sorted? Good. What you see here is a Nissan GT-R running a full lap around the Circuit de la Sarthe, better known as the location for the annual 24 Hours of Le Mans. And since this year's race takes place this weekend, there's no better time to get a beautiful, interactive look at the road course from literally every angle. The video is super cool, and trust us, you'll want to get the full 360-degree experience. We found it worked best when viewed on an iPhone or Android, because as you move the entire phone with your hand, that controls the camera's movements.
