Infiniti's variable compression engine in the 2019 QX50 is the first of its kind

The world's first variable compression ratio engine is here, in a production car. That car is the 2019 Infiniti QX50, debuting this week at the Los Angeles Auto Show. The midsize crossover has seen a refresh that has brought it an all-new platform together with new driver assist features, but it's the engine that's the centerpiece here. Nearly everything is continuously variable under the hood of the QX50 – not only the new shift-by-wire XTRONIC CVT. The new VC-Turbo gasoline engine is able to change its compression ratio from 8:1 to 14:1, or anything in between depending of the driving situation; whether there is need for top-end power or turbodiesel-like torque from low revs, or optimized fuel economy. The pistons' reach is continuously adjusted by an electric "Harmonic Drive" motor, which controls a multi-link system, affecting the top-dead-center of the pistons and changing the compression. The engine can also switch between efficiency-maximizing Atkinson cycle and regular combustion cycle, on the go – and there's both multipoint injection and gasoline direct injection employed. The result is 268 horsepower at 5,600 rpm and 280 pound-feet of torque at 4,400 rpm; good figures for a 2.0-liter four-cylinder gasoline engine with a single-scroll turbocharger. Infiniti says that the FWD version's fuel economy of 27 miles per gallon combined is 35-percent better than the previous-generation V6 engine; in AWD guise, it reaches 26 mpg, which is a 30-percent improvement. The new engine is pretty much all-aluminum, but the vaguely magical-sounding "transformative multi-link components" behind the variable compression system are made from high-carbon steel alloy. The engine's multi-link system also enables it to do away with any balancing shafts, and Infiniti compares its smoothness to a V6 rather than a regular four-cylinder. In addition to the aforementioned tech, the VC-Turbo engine has the world's first active engine mount vibration damping system to smoothen its operation even further. Related Video:

2020 Infiniti Edition 30 cars debuting at Pebble Beach Concours d'Elegance

Infiniti is celebrating its 30th anniversary at the Pebble Beach Concours d’Elegance next week, and itÂ’s rolling out a special edition for several models in its lineup. The anniversary cars are to be called Edition 30, and all of them feature similar changes. YouÂ’ll be able to get an Edition 30 for the Q50, Q60, QX50, QX60 and QX80. ThatÂ’s two sedans and three SUVs that are said to arrive in dealers this fall as 2020 model year cars — even though Infiniti launched in 1989, the first car it sold was a 1990 model year, so this matches up perfectly. Pictures of the Edition 30 cars are scant, but weÂ’ll be able to check them out in person at Pebble next week. Infiniti says they all feature special dark chrome accents in the exterior grille surround, fender trim and a little around the rear end, as well. YouÂ’ll get black side mirrors, dark gunmetal gray wheels and a body color rear apron. Additionally, all of them will be equipped with the ProAssist package as standard. This package includes driver assistance features like adaptive cruise control, distance control assist, a 360-degree camera, backup collision intervention and predictive forward collision warning. Pricing isnÂ’t available at this point for the special edition models, and we don't know if production numbers will be limited, either.

The Infiniti QX80 Monograph concept is fully revealed ahead of New York

The big Infiniti QX80, the largest SUV in the company's range and related to the Nissan Patrol sold around the world, is frankly in need of a facelift. The last time the big lug went under the knife was in 2014, and it was a pretty mild nip and tuck. The aging SUV was never much of a looker anyways, although it is certainly distinct. The Monograph concept, which is coming to the New York Auto Show next week, is a preview of where the QX80 is headed. And as we saw in the teaser last week, this styling direction is an improvement. The headlights migrate higher on the front fascia, making the thing look a little less like a sad porpoise and more like a tech-heavy SUV with serious presence. Some of this is simply concept car fantasy, sure – note the lack of mirrors, a favorite concept car trope that'll be replaced by real mirrors for production. But as Infiniti says, the concept "illustrates how the design of INFINITI's QX80 could evolve". Translation: expect the general shape and overall styling to make it to a production vehicle, unless somehow this concept gets roundly panned at the show. Since it seems to be an inarguable improvement over the current vehicle, the inevitable march towards production seems assured.
