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:

Infiniti QX Inspiration fails to drive onstage at Detroit Auto Show reveal

Update: The concept car has made it to the stage, and is spinning on its dais. "Ladies and gentleman, the Infiniti QX Inspiration. It's here, but you can't see it," were the words spoken on the Infiniti stage as the new electric concept crossover's promo video ended. That's right, on Infiniti's 30th anniversary of existence — the brand was launched here in Detroit — its big reveal was never actually revealed at the Infiniti press conference. "It's a concept car," Nissan said lamentingly. Yes, it most certainly is a finicky concept car. We walked out of the hall to see the QX Inspiration sitting, with its hood up, unmoving with Infiniti folk milling around it. This content is hosted by a third party.

Pre-written lines were read, detailing small bits here and there that nobody managed to see. However, we were determined to see the car, and managed a short glimpse before being told to move along and wait for it to (eventually) make it onto the stage for photos. Check out all the details in our post that went up as Infiniti revealed all the details of the car, minus the actual vehicle. The design is quite striking, with a heavy Japanese tilt both inside and out. Once Infiniti gets it out there (we'll update when they do) we'll have shots of it from the swiveling dais it was meant to grace during the "official" reveal. This content is hosted by a third party.

Infiniti lays out four upcoming models, electric future to dealers

Infiniti recently held a meeting in Los Angeles for approximately 200 of its North American dealers. Much of the talk was geared toward calming skeptical franchise owners about the brand's staying power. To bolster that argument, Infiniti corporate gave the retailers a sneak preview of upcoming models intended to liven up a portfolio that's largely seen as stagnant. As Automotive News reported, dealers were treated to a first look at two gasoline models and two electric ones. All four were either crossovers or SUVs. Firstly, an all-new QX80 is expected to debut for model year 2024. Infiniti plans to move it upmarket with a price tag north of $100,000 to compete with Cadillac and Lincoln. We would expect a starting price below the six-figure threshold, with only top trim models going over the line.  AN describes the QX80's exterior design as blockier than its predecessor's, with a new corporate grille. Details include "piano key" head and taillights as seen on the QX55, as well as Tesla-esque door handles that are flush with the paint when not in use. Using the next-gen version of the popular Nissan Patrol as its base, the flagship SUV will replace its 5.6-liter V8 with a twin-turbo V6 that puts out about 450 horsepower. That's 50 more than the V8, but should return better mileage than the current 15 mpg combined. Luxury features reportedly include an air suspension that lowers when parked to make climbing in and out less strenuous, a 24-inch display spanning the dashboard, and plenty of legroom for second- and third-rowers. Expect a summer 2023 debut.  An all-new model called the QX65 will be positioned as a Lexus RX rival. Though based on the QX60, which is itself based on the Nissan Pathfinder. It loses the third row for a more coupe SUV-like profile. It's described as having the grille of the upcoming QX80 but "shark fin taillights".  Infiniti was one of the first companies to proclaim an electric lineup within a certain timeframe. That date was 2030, but the brand now lags behind BMW, Lexus and others. AN's report has a new Q70 sedan going on sale by the end of 2026 as Infiniti's first all-electric model. Attendees recounted a design that takes off from where the discontinued Q70 left off but with proportions that include short overhangs and a longer wheelbase. A new lighting signature illuminates the full width of the car. Comparisons were drawn to the Tesla Model S and Porsche.
