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:

2017 Infiniti Q60 Coupe debuts with 400-hp V6

Infiniti killed it with the G35 Coupe in 2002, its second act being the G37 in 2008. The third act has officially begun, the 2017 Q60 Coupe launches today at the 2016 Detroit Auto Show. It hasn't strayed far from the concept shown a year ago, the major tweaks being government-approved headlights and side mirrors. Without discussing numbers, Infiniti says the new car is lower and wider than the current Q60, with a lower center of gravity, and it is more powerful and efficient. Much has gone on with the rolling stock, too: tighter wheel gaps, staggered tires on some models, wheels designed to absorb road vibration, and optional 20-inch alloys available for the first time. In the US, there are two engine choices with three levels of output. The twin-turbo 3.0-liter V6 comes with either 400 horsepower and 350 pound-feet of torque, or 300 hp and 295 lb-ft. In the US that will mean a boost of 70 hp and 80 lb-ft over the 3.7-liter V6 in the current car, and Infiniti estimates a combined fuel economy rating of 22 mpg. The 300-hp unit has a provisional rating of 23 mpg, the increased efficiency down to bodywork shaping and an active shutter behind the grille. A direct-injected, 2.0-liter, four-cylinder turbo is the second engine, getting 208 hp and 258 lb-ft and an estimated 24 mpg in the US. All engines will shift through an adaptive seven-speed automatic transmission. G'bye, manual gearbox. A Drive Mode Selector can dial through six settings, the Customize option throwing up three more individual choices to get the most from the updated internals. The V6 models can be optioned with Infiniti's second-generation Direct Adaptive Steering and brand-new Rack Electronic Power Steering that claims to provide more linear assistance. The four-cylinder comes with a speed-sensitive rack-and-pinion setup. Revisions to the base suspension include relocated shock absorbers among a new link layout, and modified shock tuning and bushings. Above that there's a brand new Digital Dynamic Suspension that will come standard on the Sport trim, now with adaptive dampers. Both units should have improved performance thanks to stiffer crossmembers. Finally, the cockpit gets dressed in one of three trims depending on the model, with aluminum or black wood at the entry-level end, carbon fiber at the other end, and silver glass fiber for buyers who choose the white or red leather.

Infiniti to move forward with 'Nissan-plus' strategy for its future cars

Sales at Infiniti in 2019 were down in the dumps. While the market as a whole fell 1.2%, Infiniti brand sales were down 21%. Nissan wasn’t too far behind, with its sales sliding 9.9% year-to-year. None of those numbers look great, but Nissan COO Ashwani Gupta still sees a path forward for NissanÂ’s luxury brand, Infiniti. “We will bring back Infiniti as Nissan-plus, in terms of product and technology," Gupta told Automotive News. “Infiniti will be great again.” Historically-speaking, Infiniti has been “Nissan-plus” for a long time over the years. Many vehicles in its lineup have been re-skinned versions of Nissans with some luxury thrown into the mix, and thatÂ’s not necessarily a bad thing. There have been some standouts, namely the original Q45 with its pioneering active suspension and shockingly sporty dynamics. And then there are the G coupes and sedans, vehicles that are still desirable to enthusiasts today. View 31 Photos InfinitiÂ’s current enthusiast offerings revolve around the Q50 sedan and Q60 coupe, both of which are rear-wheel-drive (or all-wheel-drive) cars with sporting intentions. ThereÂ’s no equivalent Nissan sold in America, but the Q50 is the Nissan Skyline in Japan. ItÂ’s impossible to know what the fate of these rear-drive-based cars will be, but a few possibilities lie ahead. Infiniti could really lean in to the “Nissan-plus” nomenclature and repurpose the new Altima as an Infiniti sedan. More likely, however, is a move to electrification. The Nissan IMs Concept and Infiniti Q Inspiration Concept both suggest that the company is interested in creating electric sedans. A “Nissan-plus” electric sedan sure sounds a whole lot better than a front-drive-based rebadged Nissan. InfinitiÂ’s biggest problem at this second is the lack of new product on the market. Its QX50 crossover is the most recent big redesign weÂ’ve been witness to, but it needed replacements yesterday for the QX60, Q50 and Q60 to be competitive with others in those segments. Both Lexus and Acura are outpacing Infiniti by a wide margin. The path forward as “Nissan-plus” also suggests Infiniti aims to be a premium brand, rather than a full-fledged luxury brand competing toe-to-toe with Audi, BMW and Mercedes-Benz. ThatÂ’s consistent with how the brandÂ’s cars have stacked up in recent years, even as it collaborated with Mercedes to put an Infiniti badge on the GLA crossover.
