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.

2019 Infiniti Q50 Signature Edition brings its flourishes to New York Auto Show

The 2019 Infiniti Q50 Signature Edition is coming to the NY Auto Show as a limited edition version of the sport sedan. Infiniti hopes to draw folks in with a new front and rear fascia, differentiating it slightly from the rest of the Q50s out there. Every Signature Edition will come equipped with the 3.0-liter twin-turbo V6 under the hood that produces 300 horsepower. The bright 19-inch alloy wheels seen on this car are Signature Edition exclusives, according to Infiniti. Then you get your requisite Signature Edition badging on the trunk of this Q50. The inside gets some special touches with "Kacchu" aluminum trim and full leather sport seats. Infiniti makes a bunch of pay options standard equipment on the Signature Edition. These features include Infiniti's ProAssist bundle that includes niceties like blind-spot warning, rear cross traffic alert and backup collision intervention. You get heated seats, a heated steering wheel and navigation, as well. Infiniti is offering the Signature Edition with five different colors: Black Obsidian, Graphite Shadow, Liquid Platinum, Pure White and Iridium Blue. You're looking at the blue in the one photo Infiniti has provided pre-auto show. Infiniti hasn't given pricing or how many Signature Editions it will build, but you'll be able to buy one in May this year. Expect a low number to be available and a higher price for the "exclusivity."

Infiniti Q50 Eau Rouge to cost over $100,000?

Enthusiasts have been clamoring for Infiniti to build a car like the Q50 Eau Rouge for years. In concept form, it employs the GT-R's much-loved 3.8-liter twin-turbo V6, tuned to produce 560 horsepower and 442 pound-feet of torque, with the whole works slid underneath fetching luxury sedan bodywork with carbon fiber aero aids. At this point, the model is rumored to be all but certain for production. The company recently even put Sebastian Vettel in one to show it off. However, Infiniti President Johan de Nysschen is suggesting that the model's lifetime could be brief, limited and rather expensive.
The Infiniti boss recently gave a long interview to Motor Trend that spilled a lot of beans about the Eau Rouge. While he refused to officially admit that the super sedan was on the way, he admits that he's "pushing the Eau Rouge concept for commercialization."
According to de Nysschen, if built, the production version will hew closely to the concept with the engine from the GT-R, but the seven-speed automatic transmission and all-wheel drive system will come from the Q70. And while that would make the Eau Rouge a performance powerhouse, it might also be a rarity on the road:
