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 QX55 crossover coupe teased again, hints at FX looks and a surprise out back

Infiniti plans to launch five new vehicles in the next three years. We got an abstract squiggle of the first one in August, when Infitini teased the coming QX55 crossover coupe during Monterey Car Week. Said to act as a medium that would communicate design language from the dearly departed FX crossover, the QX55 is meant to infuse a lot more design mojo to the conventional QX50 crossover that it's based on. The Japanese luxury brand just dropped the second teaser, this one revealing a swath of greenhouse and shoulder, and indeed, an arc of chrome trim that could have been traced from FX production drawings. The attention-getter here is what comes behind the greenhouse: A tailgate extension with the makings of a stubby trunk.  Positive reviews have come from a group of media to whom Infiniti showed a matte gray pre-production version of the QX55. The front diverges from the QX50 only in a few details, while the roofline isn't as coupe-ish as it might be because designers wanted to ensure adequate headroom for rear seat passengers. The steep rake has been saved for the area aft of the C-pillar, convincing one scribe to write that "the QX55 reminds us most of the Audi Q8, which also lacks swooping silhouette and looks more like a lifted hatchback." The rear fascia is said to look "cleaner and more modern than Infiniti’s current midsize crossovers," even though the jutting rear presents a vertically flat lower hatch that looks "a bit boxy." Having moved the license plate holder to the bumper, the wide expanse is home to a larger Infiniti badge and logo script with an "I" that serves an as-yet-undisclosed function. At the edges come taillights with a "sharp new piano key design." One site summed up with, "this is a gorgeous crossover coupe that will turn heads." The QX50 is expected to debut in the first three months of 2020, with an on-sale date sometime next summer.

Nissan and Infiniti recall 1.2 million vehicles because backup camera might go blank

Nissan North America has issued a recall for more than 1.2 million vehicles due to the ability to change backup camera settings to the point where there is no image in the display. The recall, which was filed with NHTSA on Sept. 12, 2019, includes cars, trucks, crossovers, SUVs, vans, and coupes across both the Nissan and Infiniti lineups.  Reported by Automotive News, NHTSA recall No. 19V654000 affects a total of 1,228,830 vehicles across two brand lineups and more than two dozen models. It includes the 2018-2019 Nissan Altima, Frontier, Kicks, Leaf, Maxima, Murano, NV, NV200, Pathfinder, Rogue, Rogue Sport, Sentra, Titan, Versa Note, Versa sedan; and 2018-2019 Infiniti Q50, Q60, QX30 and QX80. It also lists the 2019 Nissan GT-R and Taxis, as well as the 2019 Infiniti QX50, QX60, Q70, and Q70L. According to the recall, it is possible to adjust the backup camera and display settings "such that the rearview image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse." Although this type of occurrence would be extremely rare and most likely a mistake made by the driver, its real possibility means all of these cars are technically breaking the law. Federal Motor Vehicle Safety Standard (FMVSS) No. 111, "Rear Visibility," says so. According to Automotive News, this recall is not limited to the United States and also affects vehicles in Canada, South Korea, and Israel. The recall begins Oct. 19, 2019, and Nissan will provide affected customers with a free software update to fix the issue.
