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 take over for Renault in Formula E

Formula E has generated a lot of news lately, even in the off-season, as major automakers continue to either join the series or express interest in participating. The inclusion of a number of European rivals makes the series particularly interesting. One thing missing from the lineup is a Japanese automaker. That will change, though, as Motorsport reports that Nissan will be taking over its Alliance partner Renault's spot on the starting grid. It's not confirmed when the switch will happen, but with the Renault e.dams Z.E. 17 (seen in testing above) already having been unveiled for next season, it's likely the switch will come in for the 2018/19 season when the series moves away from the practice of swapping cars mid-race. Renault has been a successful part of Formula E from the very beginning, providing (with partner Spark) the cars each team used in the first season, and scoring the series' first Team Championship in 2015, and then again in 2016 and 2017. Nissan, though, has the globally popular Leaf EV, and has been eyeing an entry into Formula E for some time now. Joining the series will not only boost the visibility of Nissan's electrification strategy, it will do the same for its Nismo arm as well (and, as we've already learned, there could be a Leaf Nismo offered in the future). The change would also free up resources for Renault to focus on its F1 efforts. As Motorsport also reports, Formula E CEO Alejandro Agag has said of the Japanese brands Nissan, Honda and Toyota, that "one of those three, maybe two, will end up" in the electric racing series, without elaborating further. Nissan isn't expected to confirm its Formula E entry soon, but it could happen at the Geneva Motor Show next year. Related Video: This content is hosted by a third party.
