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.

Infiniti VC-TWe’ve mused on Infiniti’s Variable Compression Engine in the past, calling it everything from a chameleon to the holy grail. Its killer app? The ability to changes the distance the pistons travel in their cylinders by as much as 6 mm, or about a quarter of an inch.

Why is this important? Because it is, arguably, the first major change to the workings of a internal combustion engine in more than a century.

It was 1998 and my friend Tom had just picked up a 1991 Eagle Talon TSI AWD.

“Ok, go ahead and floor it, but don’t rev it past 5,000 rpm,” Tom said.

I mashed the throttle and … nothing happened.

We were moving, but it was at the pace of a Toyota Corolla and nowhere near the rate of acceleration promised by the 2.0-liter turbo’s claimed 195 horsepower.

Disappointed, I left my foot on the throttle for a few seconds. Suddenly, I heard the whistle of the spooling turbo and a sudden shove of boost kicked in.

Four-cylinder turbo engines from the ‘90s were all similar to this. While they generated relatively big power at the top end, they also suffered from massive turbo lag and had fuel economy similar to a much larger V8.

Nissan’s new Variable Compression Turbo engine promises big power, minimal turbo lag, and decent fuel economy using some new trickery.

Is this the holy grail of turbocharged motors?

INFINITI four-cylinder turbocharged gasoline VC-T engine

Infiniti has a revolutionary new engine in the works that’s both a high-compression mileage-maker and a low-compression pavement burner, giving drivers the option of being lean or mean at any given time.

The world’s first variable compression engine, dubbed the VC-T, ate up 20 years of design work before Infiniti went public with its achievement. The automaker plans to unveil the revolutionary engine next month, at the Paris Auto Show. (Read More…)
