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 is blazing an unconventional path to electrification

When it comes to electrification, Infiniti has a history of speaking a great deal but doing little. The Nissan-owned company's plug-in offensive will start in the 2020s, and it provided preliminary details about the technology that motorists can expect to find in showrooms in the not-too-distant future. Eric Rigaux, Infiniti's general manager of product strategy and planning, told Roadshow the firm's engineering department is putting the final touches on two forward-thinking electrified powertrains. The first one will run solely on electricity, while the second one will rely on a gasoline-powered generator to provide more range. Both are being developed to fit into a flexible new platform. Technical details about the electric setup remain vague, so we don't know how big of a battery pack Infiniti will use, or how many motors will draw electricity from it. However, Roadshow learned the gasoline-electric layout will never need to be plugged in, because a 1.5-liter, three-cylinder engine equipped with Infiniti's innovative variable-compression technology will produce the electricity it needs to run. The triple won't directly spin the wheels; it will channel the juice it creates to a battery pack. It's not a zero-emissions solution, but it's one that makes a lot of sense, because users won't need to wait for a charge, and they'll be able to drive for about 500 miles between fill-ups. The now-defunct Chevrolet Volt featured a similar drivetrain, but owners had the possibility of plugging it in. Infiniti won't give motorists that option; there won't be a plug anywhere on the car. Fluid-filled motor mounts and active noise cancellation will ensure the passengers don't feel or hear the triple whirring away. Meanwhile, two electric motors (one over each axle) will deliver between 248 and 429 horsepower; final specifications haven't been signed off yet. And, because power will come from gasoline, there's no need to integrate a bulky battery pack into the chassis. Infiniti's future gasoline-electric models won't require anything bigger than a 5.1-kilowatt-hour unit, which can unintrusively be stuffed under the trunk floor or sandwiched between the floor and the rear seat. Infiniti chose a crossover to inaugurate its battery-electric powertrain; the QX Inspiration concept (pictured) unveiled during the 2019 Detroit Auto Show shed light on what the model will look like.

This is the 2017 Infiniti Q60 Coupe totally exposed

Right about now, Infiniti's holiday card to Autoblog is going to get "lost in the mail." That's because we're going to spoil the automaker's next big debut nearly two full months ahead of schedule. Oops. What you see above comes from a promotional shoot for the new Q60 coupe. The photos taken here will probably serve as the official images when the new coupe bows in January at the 2016 Detroit Auto Show. The look is more or less what we expect, serving as a literal translation of the Q60 coupe concept that debuted last year in Detroit. That means it's darn handsome. The front fascia is bold, with Infiniti's trademark grille dominating the nose. As we predicted in our most recent round of spy photos, the Formula One-inspired front bumper has been ditched in favor of a more conventional unit, likely owing to Infiniti parent Renault-Nissan's pending divorce from the Red Bull Racing team. This is not a bad thing. There was just too much Mercedes-Benz SLK in the concept's front bumper. The pert tail features a remarkably short deck and an aggressive roofline, although we aren't sure how the company's heavily kinked beltline works on a two-door model. The profile is also highlighted by a set of vents just aft of the front axle. Overall, we're finding the new Q60 coupe to be a worthwhile alternative to the BMW 4 Series, Audi A5, Lexus RC, and the upcoming Mercedes C-Class coupe in terms of aesthetics. As previously reported, the most powerful Q60, likely featured here, will be offered with a 3.0-liter, twin-turbocharged, 400-horsepower V6. A 2.0-liter turbo pilfered from Mercedes will serve as the base engine. As for the cabin, we unfortunately don't have much to show you (we need to leave something for Infiniti to show in Detroit, right?). We can tell you that the overall cabin should be reminiscent of the Q50 sedan, and the Q60 isn't likely going to depart much from the controls and infotainment on its four-door sibling. Related Video:
