The best factor about Infiniti’s newly redesigned QX50 crossover has nothing to do with its appears, its technological goodies, and even its means to (kinda) drive itself. No, the very best factor about this car is sitting below the hood, and it is acquired an vital message for the drivers of Earth: Stories of the interior combustion engine’s demise is perhaps a tad untimely.

That is as a result of this compact five-seater options the world’s first variable compression engine. We’ve recognized about this intelligent system for a couple of years, however now it is lastly coming into the market.

The trick lies within the engine’s means to alter the compression ration, which determines how tightly the pistons squeeze the air and gasoline earlier than the spark plug ignites the combination (that is the combustion bit). It does that by altering the angle of a middle hyperlink, which rotates across the crank shaft and separates higher and decrease piston hyperlinks, and thus the gap the piston travels up the cylinder.

Like most of those techniques, it actually solely works on the freeway, and nonetheless requires hands-on participation from the driving force (in any other case it beeps aggressively), but it surely has a straightforward to grasp person interface, a bonus within the too typically murky world of semi-autonomy. It additionally capitalizes on Infiniti’s steer-by-wire expertise to generate extra exact management of the car’s reactions to obstacles and different autos.

When you’re desirous to take residence the brand new engine—then let it drive you round—you have acquired till late 2018 to save lots of up $35,000.
