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 electric crossover will mark a milestone at Detroit Auto Show

In November, it was announced that both Nissan and Infiniti will display EV concepts at the 2019 North American International Auto Show in Detroit, taking place in January. Previously, it wasn't made clear what kind of vehicles they would be, but Infiniti stated today that its Detroit concept will be an electric crossover. Both the Nissan and Infiniti concepts will continue the design direction shown by Infiniti's Q Inspiration concept, and later next year, there will be stylistically similar cars shown at the Tokyo Motor Show in October. The luxury brand has released the above teaser photo of the crossover, depicting sharp headlights and a lit grille outline surrounding the badging. We can also see large wheels and tires and sizeable, defined wheel arches. Future Infinitis will be electrified from 2021 on, featuring either serial hybrid tech or full electric drivetrains. Serial hybrid refers to using Nissan's e-power technology, which relies on range extender engines instead of a large combustion engine (such as Infiniti's lauded VC-Turbo). The Detroit Auto Show is also a significant event for Infiniti, as the brand and its first car, the grille-less Q45 luxury sedan, was first displayed 30 years ago at the 1989 NAIAS. "Thirty years ago, as a 24-year-old designer in the audience, I saw the birth of Infiniti in person and am proud to be part of the journey of creating iconic luxury automobiles," said Nissan's senior vice president for global design, Alfonso Albaisa. Meanwhile, Infiniti's November 2018 sales were the best November numbers in the brand's history. "The concept car we will show in Detroit is the beginning of a new era for Infiniti, and an illustration of where we want to go with the brand," said Karim Habib, Infiniti's design director. Earlier, Albaisa echoed his statements, telling us how electrification can inspire the brand's future design thanks to the battery packs' size development, saying: "It's getting denser, it's getting thinner, the cars are able to get a little bit bigger, more space, we can really do much more."

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.
