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.

Next Nissan GT-R to take cues from GT-R LM Nismo Le Mans entry

For those wondering why Nissan named its coming Le Mans Prototype the GT-R LM Nismo, colliding the two worlds of sports car and prototype racing, an article in Autocar might have the answer. The deeper union is explained by saying that the next-generation GT-R will use "hybrid technology that will closely align it" with the GT-R LM Nismo.
The point could be further driven home by the fact that the GT-R LM Nismo will begin its FIA endurance racing campaign next year, and the next GT-R is due to debut next year as a 2016 model. The expectation is that it will use a hybrid system possibly dubbed R-Hybrid and perhaps developed by Williams. Just like performance car makers Ferrari and Audi, Nissan wants its racing efforts to pay off with road car technology, company vice president Andy Palmer saying they "want to link technological linkages between future evolutions of the GT-R and evolutions of what we do in LMP1, and the two do go in both directions."
The bigger question is, with the GT-R getting hybrid assistance, will it also get the weight gain that usually comes with it? Enthusiasts would love to see the trend reversed, especially on a car that's already no lightweight.
