2021 Infiniti Q50 and Q60 recalled for stalling issue

Infiniti is recalling 2021 Q50 sedans and Q60 coupes due to faulty engine-management software. The issue is with the engine control module (ECM). After rapid acceleration, the ECM can reduce the fuel supply to the engine too much, resulting in the engine going into limp-home mode and possibly stalling. A total of 12,943 cars are affected by the problem. Infiniti will commence the recall on May 25. Owners will be notified and asked to bring their cars in for software reprogramming. The fix will be performed at no cost. Owners who are concerned about the issue can reach out to the manufacturer at 1-800-662-6200. Infiniti's reference number for this recall is R20C5.

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 all but certain to produce Q50 Eau Rouge [w/video]

These pages are full of projects that automakers have tried to get moving but never quite managed to. And Infiniti has had its fair share, particularly when it comes to high-performance models. It's tried to drum up excitement with the Infiniti Performance Line and with its partnerships with Red Bull Racing and its star driver, but models like the G37 IPL and FX Sebastian Vettel edition never amounted to a real challenge to the likes of Mercedes-AMG and BMW's M division. There was talk of a sedan version of the Nissan GT-R to wear an Infiniti badge, but those rumors amounted to even less. The Q50 Eau Rouge, however, could finally be the ticket.
The concept debuted at the Detroit Auto Show a few months ago without an engine (or at least not one we were made aware of) but with all manner of carbon-fiber aerodynamic components. It then rolled in to Geneva with the beating heart of the GT-R - a 3.8-liter twin-turbo V6 tuned to 560 horsepower and 442 pound-feet of torque - and arrived in Beijing earlier this week in an even more evolved form. And according to the chatter coming out of China (whose financial hub of Hong Kong, incidentally, serves as Infiniti's home base), it's all but certain to be approved for production.
"At this stage it would take more to stop the car getting made than to start things," says Auto Express, citing an unnamed source. The finished product would look much like the versions we've seen until now, and while it would be available in an array of colors, that metallic blood red could emerge as Infinit's signature performance color.
