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:

2025 Infiniti QX80 First Look: Can it command a hundred grand?

NEW YORK CITY — If Infiniti has its way, the all-new 2025 QX80 will be the flagship SUV that leads NissanÂ’s luxury marque into a much-needed renaissance. By the time the 2025 QX80 debuts, the current generation will have been on the market for 15 years. The model dates to 2010, when it debuted as the QX56 (prior to InfinitiÂ’s naming system revamp). The QX56/QX80 received a lot of hate for avant-garde styling that appeared to have been birthed from an H.R. Giger space horror. The 2025 iteration tones that down significantly with fewer curves and more chiseled lines. As previewed by the QX Monograph concept, the complete absence of surfacing on the sides is as unfussy it gets. The nose retains InfinitiÂ’s trademark double-arch grille, inspired by the enduring stone bridges of traditional Japanese gardens. Similarly, its vertical slats are meant to evoke the spires of a bamboo forest. The new Infiniti logo is now 3-dimensional, with the “infinite road” dropping into the center like a black hole. Unlike a black hole, it illuminates in an eye-catching effect that, thankfully, feels less pretentious than MercedesÂ’ glowing stars. At the rear, a full-width taillight bar recalls lights reflected in water and is made up of more than 300 LEDs. The thin lights flanking the grille are DRLs, while the QX80Â’s real headlights are embedded in nooks just above vents on either side of the front fascia. Happily, those vents are functional, directing cooling air to beefy two-pot calipers and 13-inch discs. Likewise, the (finally de-chromed!) driverÂ’s side fender vent acts as a heat extractor. That heat is generated by a new twin-turbo 3.5-liter V6 that replaces the outgoing naturally aspirated V8. Mated to a 9-speed automatic, it hails from the same engine family as the GT-R supercar and makes 450 horsepower and 516 lb-ft of torque, a surge of 50 horses and 105 lb-ft. At the same time, Infiniti says it gets 20% better fuel economy. Many forget that beneath the predecessorÂ’s alien beluga sheetmetal was a solid luxury SUV with real off-road bones. It was built on the same platform as the Nissan Patrol, a hard-core 4x4 that competes toe-to-toe with the legendary Toyota Land Cruiser in foreign markets. Come 2025 the QX80 will continue to share a chassis with the new Patrol, albeit an all-new body-on-frame unit that Infiniti says has 57% more lateral stiffness than the outgoing model and 300% increased torsional stiffness.
