2019 INFINITI QX50

Think of an occasion in which something really good appeared in a place where it was underappreciated. A fantastic steak at the downtown greasy spoon, perhaps? Beautiful new windows installed in a student rental house? My writing on this website? Wait, I wasn’t supposed to say that last one out loud…

Buried in the mire of Ghosngate at Nissan is some nifty new tech that should be turning the car world on its ear. The company’s variable compression engine, displacing an industry-typical 2.0 liters from a turbocharged four pot, is actually about as far from industry-typical as Yugo was from being a class leader in fit and finish. It’s able to vary its compression from 8:1 to 14:1, thus offering the best of power and economy characteristics. It’s been called the “holy grail.”

So where does this engineering marvel and technological triumph first appear? In the company’s sports car? Don’t be silly. It’s under the hood of a grey crossover, of course.

Talk about being underappreciated.

One thing is clear — with variable compression comes a newfound lack of thirst.

Infiniti’s previous midsize QX50 crossover didn’t astound in its thrift, garnering 20 miles per gallon on the EPA combined cycle. The move to a new, front-drive platform and addition of a years-in-the-making gasoline engine for 2019 has done wonders for the model’s drinking habit, however, and Infiniti engineers pegged the MPG figures right on the nose.

With the 2019 QX50‘s fuel economy now confirmed by the EPA, it begs the question: just how much of the model’s thriftiness can the variable compression engine take credit for? (Read More…)

2019 Infiniti QX50

Miles per gallon can vary from driver to driver. We all know that. Now, Infiniti is trying out an engine that can vary its compression ration from scenario to scenario.

Miles per gallon is also a key spec for the new QX50, since the variable compression ratio tech is responsible for a claimed improvement in combined fuel economy – 35 percent for front-drive vehicles and 30 for all-wheel-drive units.

As is the usual case on first drives, I had no chance to verify those numbers – which, according to Infiniti, work out to 27 mpg combined with front-wheel drive and 26 mpg with all-wheel drive. Improved fuel economy is just part of the picture when it comes to variable compression, which is making its production debut in the 2019 Infiniti QX50.

You saw a teaser the other day, but here’s the real thing. Infiniti’s next-generation 2019 QX50 midsize crossover has appeared online before its official unveiling at next week’s L.A. Auto Show.

The model’s uncloaking doesn’t yield any great design surprises, as this next-generation model — bearing Infiniti’s new “Powerful Elegance” styling — was preceded, somewhat oddly, by its own namesake concept vehicle. One surprise, however, is the model’s anticipated fuel economy.

With a 2.0-liter variable compression four-cylinder resting under the hood, the new QX50 sips less gas than initially claimed. (Read More…)

Nissan’s luxury division isn’t saying it’s the next-generation QX50, but everything we know about that model and its revolutionary (and potentially risky) engine points to one conclusion.

For now, and until the vehicle’s unveiling at the L.A. Auto Show on November 28th, Infiniti simply refers to it as an “all-new model” — one boasting “world-first” technology. The technology’s no mystery, as after two decades of development Infiniti plans to launch a 2.0-liter variable compression gas engine. Expect class-leading interior volume, the automaker tells us.
