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:

2022 Infiniti QX55 marks the company's foray into crossover 'coupes'

Using a formula proven by the major German luxury car companies, Infiniti is now getting in on the crossover "coupe" game. The 2022 Infiniti QX55 takes the QX50 small crossover and adds a fastback roofline for a sportier look. Infiniti says the design makes the QX55 a spiritual successor to the FX crossover of the mid-to-late-2000s and early 2010s. We're not sure if the mechanical bits live up to the rear-drive-based FX chassis, but the low roof and curvy body do share a connection to that old SUV. In fact, the QX55 looks rather striking, and the flowing lines work nicely with the simple, arcing roof. Some other small tweaks to the base styling emphasize the QX55's style focus including a more pronounced grille with larger air intakes surrounding it at the front. At the back, the license plate mount has been moved to the bumper, allowing for prominent Infiniti lettering on the hatch. Additionally, 20-inch wheels are a standard feature on all QX55 models. The rest of the QX55 is basically the same as the QX50. It shares the turbocharged, variable-compression engine making 268 horsepower and 280 pound-feet of torque. It's mated to a CVT and all-wheel-drive, which is standard on all QX55 models. The interior is carry-over with dual infotainment screens and an asymmetric, driver-focused dash design. Like the QX50, it can be slathered in two-tone leather for a very premium feel. The debut vehicle features a bold black and red color combination. The QX55 goes on sale this coming spring. It will be available in three trim levels: Luxe, Essential and Sensory. Pricing hasn't been announced, but expect it to be a bit more costly than the equivalent QX50. For reference, a QX50 Luxe with all-wheel-drive starts around $44,000, and at the other end of the spectrum is the QX50 Sensory with all-wheel-drive starting at around $53,000. Related Video:

Infiniti Q60 dies at year's end

In 2021, Automotive News' Future Product Pipeline coverage for the Infiniti brand contained a single entry for 2023: "Infiniti Q60 ends in 2023." Turns out the report of the Q60's death was true; the brand confirmed to Car and Driver that the coupe ends production at the end of this year. We wish we were surprised at the news or the rationale. An automaker spokesperson told the magazine, "We are focusing on the most popular luxury automotive segments such as crossovers and SUVs, as well as the upcoming EV we recently announced that will be built here in the U.S." The official justification didn't address the fact that dealers sold 2,728 units of the Q60 in the U.S. last year, 64 units fewer than achieved in 2020, and 2,315 units fewer than dealers moved in 2019 — the year Q60 sales fell off a cliff after selling more than 9,000 units in 2018. Consider this another step in the "three-phase company transformation" that Chairman Peyman Kargar is in the second stage of working through. The first phase of recovery ended this March, the luxury automaker getting back to profit globally. The current second stage that will revamp, electrify, and expand the lineup is predicted to last for the next four years. The spearhead will be the new QX80 SUV, planned for late next year or early 2024 with ambitions to challenge the Cadillac Escalade, Lexus LX, and Range Rover. That luxury club barred Infiniti from entry awhile ago, so Kargar's talking about profound turnaround. As for the Q60, the shame is that a car with sweet looks and even sweeter power never got the interior or driving dynamics to match. Perhaps the return of a much better Nissan Z can provide fodder for a proper Infiniti coupe once the luxury division has restored its momentum. The spokesperson told Car and Driver that Q60 inventory should last until well into 2023, so anyone looking for a 400-horsepower bargain with a six-speed manual should mark their calendar for early next spring.   Related video: This content is hosted by a third party.
