Audi is reportedly working on a brand new four-cylinder engine which will run just as smooth as a larger six- and eight-cylinder motor.

The downsizing trend is in full swing as even large executive sedans will soon get four-cylinder engines so it shouldn't come as a surprise that Audi is allegedly planning a new four-cylinder to power its bigger models. According to Autocar, it will run just as smooth as a larger six- or eight-cylinder engine thanks to a special design which has already been patented.

According to the patent application, Audi's all-new four-banger is an "internal combustion engine with multi joint crank drive and additional masses on articulated connecting rods for damping free inertia forces." In this new configuration, the pistons and conrods are offset to one side of the crank and are connected to it through a rocker-style link. In a conventional four-cylinder motor, the conrods and pistons are running in line with the crankshaft.

Since the pistons won't move on the same axis as the crankshaft, the newly developed four-cylinder engine should prove to be very smooth and in terms of packaging will be just as wide as the conventional V engine but with lower fuel consumption and fewer CO2 emissions.

A possible first application for this engine will be the next generation A8 likely to come out sometime in 2016 and go on sale as a 2017 model year.
