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.

2017 Infiniti QX30 beefed up and ready for LA debut

Infiniti has released the first details and photos of its new compact crossover. Dubbed the QX30, the latest addition to the premium lineup is set for parallel debuts at the upcoming auto shows in Los Angeles and in Guangzhou, China. And with it, the luxury automaker is going after a younger demographic. Previewed by the QX30 concept unveiled earlier this year in Geneva, the new crossover joins the Q30 hatchback in Infiniti's new "entry-level" model line. Set to be produced at Nissan's mega factory in Sunderland, UK, the QX30 will be the first Infiniti to be built in Europe. But as you might discern from its introduction in LA, it'll form a vital part of the brand's strategy for the US market as well. The design looks instantly recognizable as an Infiniti, looking almost exactly like the Q30... only more rugged. Apart from the increased ride height, suitably ruggedized lower bodywork, and telltale (but slimline) roof rails, it adopts the same curvaceous, organic lines as the hatchback, and signature double-arch grille and kinked C-pillar as you'd expect from any modern Infiniti. The Japanese automaker has yet to show us much of the interior, but it promises an asymmetric design, premium materials, and ergonomic surfaces. Nor has Infiniti revealed much in the way of technical details. What it has told us, however, is that the new QX30 will encompass an all-wheel-drive system capable of sending up to 50 percent of output to the rear wheels, running through a seven-speed dual clutch transmission. Availability of diesel and gasoline engines will depend on the individual market. If its lower-riding stablemate is anything to go by, we should be looking at a 2.0-liter turbo four producing 208 horsepower and 258 pound-feet of torque. Technical specifications are due to be announced closer to its market introduction in the middle of next year. At that point, rivals like the Mercedes GLA, Audi Q3, BMW X1, and Lexus NX will be put on notice as Infiniti joins an increasingly competitive market for premium compact crossovers.
