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.

2022 Infiniti QX60 spied running around post-Monograph Concept reveal

Infiniti recently revealed the QX60 Monograph Concept, a concept crossover meant to preview the next generation QX60. Today, the first spy shots of the QX60 in production form hit our desks. There’s a whole lot we canÂ’t see under the camouflage, but it looks fairly representative of what we expect a production version of the Monograph Concept would look like. The headlights, grille design, lower opening and side air intakes all look like they were pulled straight off the concept. It also has the same hood design with raised outer edges that lead right into the A-pillar. Its droopy side camouflage does a good job of disguising its curvaceous profile and pronounced rear fenders. We can see a hint of widening at the rear fenders, and we hope that the MonographÂ’s look is translated over to production there. The mirrors were moved further down onto the doors, and the flush door handles are done away with. This tester appears much less flamboyant with normal-size wheels replacing the giant and dramatic spinners on the Concept (gallery of the concept below). Infiniti QX60 Monograph View 36 Photos Infiniti is copying the shape of the rear over to production. We can clearly make out the raked rear window, overhanging spoiler and rounded shape of the back end. The taillights are a bit difficult to see, but their general design matches up to the Concept. As for the fancy chromed exhaust area on the concept, those spots appear flat and barren on this preproduction model. ItÂ’s still heavily covered in camo, though, so we donÂ’t yet know what the rear bumper design will look like in its final form. The production QX60 is set to be revealed next year where it will likely go on sale as a 2022 model year car. ItÂ’s unclear what powertrain(s) will be lurking under the hood, but at least we know the production version wonÂ’t stray terribly far from the concept now. Related Video:

Infiniti QX60 AWD vs. Mazda CX-9 Signature

In certain ZIP codes around Dallas, Chevy's Suburban remains the Official SUV of Texas, but Infiniti's QX60 could be the Official Crossover. The Pathfinder-based three-row is everywhere. And while its popularity is based on transporting kids and their stuff, the QX60 is a more urban Suburban. Mazda's CX-9 is not as ubiquitous as the QX60 in McMansion driveways, but it has been making inroads into the near-luxury segment with its near-luxury spec. The CX-9's second generation has obviously upscale intent, in the sheetmetal and throughout the top-line Signature interior. And the prices of these two cars are surprisingly close. INFINITI QX60 AWD: The sheetmetal differentiating Infiniti's QX60 from its volume-oriented Nissan donor is attractive. The changes are subtle, and in profile the Pathfinder and Infiniti are almost identical, but the eye is drawn to the differences in the grille and D-pillar. The Infiniti has a luxury vibe with a more athletic stance. The QX60's interior surfaces seem upscale, but if you want wood it will cost you. In "building our own" and opting for graphite leather with maple trim, the wood requires another $12,000(!) of mandatory packages, including Infiniti's Premium and Premium Plus packages ($1,800 and $2,900, respectively) and $7,300 of Deluxe Tech. So, wood? We wouldn't. But if you do, know the QX60 won't match the larger QX80 in presence or passion, but it is certainly something beyond a rebadged Pathfinder. For you and your passengers, there is 156 cubic feet of interior room; with the second and third rows folded, you can accommodate 76 cubic feet of cargo. Like in most crossovers, that third row is best used by young kids, but taking six adults to lunch won't require too much gymnastics – or chiropractics. On the road, the QX60 is known more for comfort than composure; this isn't an old Buick, but neither is it a BMW. Nissan's 3.5 liter V6 produces generous power (295 horsepower and 270 pound-feet of torque), but it's transmitted to either the front wheels or all wheels via a CVT (continuously variable transmission). Nissan has tried to mitigate the quirkiness, but it's a CVT all the same. At a well-equipped base of $44,000, we like the QX60. But start adding options, and you can approach $60,000, which is real money even in the better ZIP codes. MAZDA CX-9 SIGNATURE: This, ladies and gentlemen, is dramatic. Mazda has absolutely nailed it. Using Mazda's KODO design language on a large platform could have gone wrong.
