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.

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.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
