Nope, not in car industry. Spoiler are for down force like in F1 and race cars. Like the Veyron they just lower the spoiler to do top speed. Inverter spoiler then the car will take off like the plane......lol

The aerofoil is insufficient to build lift to lift the car like planes. Airplane needs sufficient thrust to push the plane forward and enough speed to produce enough lift force to fly. The inverted spoiler at the rear of the car crest lamina flow at the back so that the turbulent air created at the tail of the car is created further behind. Hence, reduces drag right behind the car.

My apologies, it is not the inverted spoiler, it is the downward spoiler, I meant. Just like the airplane wings.

An inverted spoiler to the airplane wing, like F1 rear wings, Will increase down force and better grip. You are absolutely right, hence increase in fuel consumption.

Have a look at Alphard's and Vellfires, and estima's and many hatch back like alza and Serena, the trailing edge goes down, not upwards.
