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:

2016 Infiniti QX60 gets a facelift, Hybrid still alive

The future of the Infiniti QX60 Hybrid looked grim a few months ago, when Nissan confirmed the Pathfinder Hybrid was being discontinued. After all, the QX60 and Pathfinder are nearly identical underneath their different bodies. But with this 2016 model year refresh, Infiniti confirms that its QX60 Hybrid will indeed carry on for the new year. It's the same hybrid system as before, combining a supercharged, 2.5-liter inline-four with an electric motor for a combined 250 horsepower and 243 pound-feet of torque. New liquid-filled active engine mounts are added for 2016 in an effort to reduce overall harshness. Non-hybrid models carry on with the naturally aspirated 3.5-liter V6, good for 265 hp and 248 lb-ft. Front-wheel drive is standard with both engines, and all-wheel drive is optional. That's the biggest news for the updated QX60. Everything else baked in to the refresh is pretty standard. Up front, there's a new fascia that better aligns the seven-passenger crossover with every other Infiniti product, and the taillights are slightly more stylized than before. It looks nice, but there's still no hiding those Nissan Pathfinder bones. Infiniti says new shock absorbers and springs will help improve ride quality, and steering effort is improved with a retuned, speed-sensitive electronic power assist system. Standard, Sport, Eco, and Snow modes will help you manage the power depending on the weather and your driving style. We don't know how much this will actually improve the QX60's ride, but we never really had any problems with the luxury crossover's relaxed dynamics, anyway. Look for the QX60 to officially debut at the 2016 Detroit Auto Show, following a reveal at a media event this week. For the full details on all the super-nitty-gritty changes, check out the press blast below.

Infiniti showcases Vision Gran Turismo concept in the metal

Automakers have been clamoring to convey their ethos to a new generation and cast their brand in a positive light through the Vision Gran Turismo series. But while these concepts are designed for the virtual reality of Gran Turismo 6, some automakers have gone a step further by pulling their creations out of cyberspace and rendering them in the metal. And that's just what Infiniti has done with its design. Infiniti revealed its Concept Vision Gran Turismo back in December, striking a a sleek, low-slung form that looks more polished than a racing car but more track-focused than most concepts. It's powered (at least hypothetically) by a 4.5-liter V8 hybrid powertrain, with center-lock carbon-fiber wheels and rearward-biased 45/55 weight distribution. It's the kind of beast we'd love to drive, but while that may only be possible on Playstation, at least we know it does exist in physical reality – even if only as a full-scale model. Infiniti showcased it alongside the Q80 Inspiration and Q60 Concept at an exclusive event during the Shanghai Motor Show last week, but just revealed the photos now, so you can scope them out in the slideshow above.

Under the theme of "Aesthetics of Contrast," Infiniti Design Night showcased three design concepts showing an exciting path to Infiniti's future: the Q80 Inspiration (first shown in Paris, October 2014), Q60 Concept (Detroit, January 2015), and the Vision Gran Turismo designed especially for the latest Gran Turismo® 6™ video game. This was the first time the Vision GT was displayed as a real "flesh and bones" concept car, having only been seen and experienced digitally in GT6 prior to this event. The dramatic Infiniti Concept Vision Gran Turismo The Infiniti Concept Vision Gran Turismo is a vision of what a high performance Infiniti could look like in the future. Available for download in GT6 exclusively on the PlayStation®3 system, it was created through close collaboration with the creators of Gran Turismo®, the racing game franchise developed by Polyphony Digital Inc. that has sold more than 72 million copies worldwide.
