Infiniti Q30 spied again

The Infiniti Q30 is back in the news thanks to the imminent debut of the QX30 Concept as its crossover counterpart at the upcoming 2015 Geneva Motor Show. The siblings are Infiniti's entrants into the popular premium compact ranks, and the standard hatchback was recently spotted in Europe with the least amount of concealment yet. Granted, this tester is still pretty heavy camouflaged, but this is a lot better aesthetically than the previous garbage-bag-covered look. While the pattern makes specifics hard to discern, the translation from the motor show stand to the road appears to be leaving the Q30 Concept's styling largely intact. Up front, the squinting headlights and swollen-rectangle shape of the grille remain similar, and while they are pretty hard to spot, the slashes down the side are faintly visible from some angles. The rear hews even closer to the original design with a comparable shape for the taillights and hatch, but exhausts are much smaller on this test car. Underneath the skin, the Q30 reportedly shares its platform with the Mercedes-Benz GLA-Class, and the engine is also expected to be the 2.0-liter turbocharged four-cylinder available in Mercedes' compact lineup. Official details should start spilling out soon, though, because Infiniti wants production of the hatchback to begin in 2015 at the Sunderland plant in the UK. A launch for the US market is expected in 2016. Featured Gallery Infiniti Q30 Spy Shots Image Credit: CarPix Spy Photos Infiniti Hatchback Luxury infiniti q30 infiniti q30 concept

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.
