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:

Nissan axing Pathfinder Hybrid from 2016 lineup

The Nissan lineup gets a little smaller for the 2016 model year, as the Pathfinder Hybrid is dropped from the range. With its debut in late 2013, the electrically assisted SUV is one of the company's more recent introductions. However, it never really caught on with the public. "The Pathfinder Hybrid is not available in the US for the 2016 model year. Our emphasis is on the 3.5-liter V6 Pathfinder that achieves a best-in-class 20-city and 27-highway fuel economy," Nissan North America product communications director Dan Bedore confirmed to Autoblog. "Nissan has no announcement on future hybrid gasoline-electric powertrain applications at this time." Nissan actually ended production of the Pathfinder Hybrid in January, and "the hybrid was never a big part of Pathfinder sales," Bedore said to Automotive News. For the price premium, the electrically assisted version that combined a supercharged 2.5-liter four-cylinder and a 20-horsepower electric motor was only rated three or four miles per gallon better in EPA combined ratings than with the V6. However, while the company doesn't outline individual sales of the two, powertrain variants, the SUV is performing well so far this year. Through June 2015, sales are up 4.9 percent with 41,938 units sold. The future for the Infiniti QX60 Hybrid, which is the Pathfinder's more luxurious sibling, doesn't look very bright either. "For the United States, while the QX60 Hybrid continues to be available at some retailers across the country, our production is currently focused on the QX60 3.5 model," Infiniti spokesperson Kyle Bazemore told Autoblog. However, the vehicle is still in production at the Smyrna, TN, factory for export to places like China and Mexico. According to Bazemore if demand happens to increase in the US, "we have the manufacturing ability to make them available." Overall, QX60 sales are also up 14 percent this year in the US.

Q50 Eau Rouge to kick off series of performance Infinitis

Infiniti is desperate to position itself as a brand for performance enthusiast. It's tried to create that impression by attaching its name to the Red Bull Racing team, by sprucing up the G37 Coupe and G37 Convertible as part of its lack-luster Infiniti Performance Line, and by bringing Sebastian Vettel on board to create a special edition FX crossover. But the Japanese luxury brand knows it's going to need something more comprehensive if it's going to go up against BMW and its M models, Mercedes and its AMGs, or Audi and its Quattro GmbH-tuned RS range.
That's why the Q50 Eau Rouge concept unveiled just last week at the Detroit Auto Show was so important to the marque. But Infiniti has more in store than just a concept. Nissan desires to put the Q50 Eau Rouge - named after the notoriously challenging turn at the Spa Francorchamps circuit in Belgium - into production with a 500-horsepower engine. But in speaking to Automotive News, Infiniti chief Johan de Nysschen hinted at more good news to come.
That could include a performance version of a new flagship sedan Infiniti is said to be working on, positioned above the current Q70 to fill the void left by the discontinued Q45 that capped the brand's range before it shifted its entire naming scheme behind it. The flagship sedan would need some serious muscle to challenge the likes of the Mercedes S63 AMG and Audi S8, but Infiniti seems bent on getting there. To cap it all off, Infiniti has long been rumored to be working on a halo sports car. Whether they'll all carry the Eau Rouge name, the IPL badge or some sort of other designator remains to be seen, but we'll enjoy seeing this development progress.
