Fuel prices have skyrocketed recently, and everyone is looking for a solution to pay less for fuel, or reduce fuel consumption. This modified Subaru Impreza allowed its owner to increase its autonomy by no less than 13.7%!

This American motorist used his aeronautical knowledge and applied it in the automotive field to improve the aerodynamics of his car. Indeed, most cars create turbulence behind them, which affects their penetration into the air and, therefore, increases fuel consumption. With a simple modification, this Impreza saw its own optimized aerodynamics.

Subaru Impreza: handmade

To make his aerodynamic improvements, the author of this video made hard cardboard caps that it is stuck on its drives, but also polystyrene thermal insulation panels, cut and glued behind, leaving the taillights visible.

Small aerodynamic elements have also been added to the sides to improve air circulation. A light fixture was also added inside the structure to make it all a little more spectacular!

Subaru Impreza: significant reduction in fuel consumption

Of course, such a modification is absolutely not are not admitted to circulation on the open road. The rear license plate is also no longer visible, which could cause legal issues.

When testing the car before sticking the modifications on it, our main character recorded a consumption of 35.6 mpg, or about 6.6 liters per 100 km. After the modification was installed, he was able to record consumption of 40.52 mpg on an identical route, or about 5.8 L/100 km. AND a significant reduction in consumptioneven if in practice, it is difficult to be able to circulate with such a machine unnoticed!

Sometimes the price of fuel doubles from one gas station to another. How can this really be explained? https://t.co/Ch6YU9fbbs
