2021 F1 cars going to “be a real nasty piece of work to drive”

The aim of the 2021 regulations being put into place is to allow for cars to follow each other easier with a reduction of the amount of dirty air created by current and previous cars.

While the reduction of dirty has been proven Green says that air created from a drivers own front wing could potentially cause issues, wanting more freedom around its design to avoid any problems.

“I think there are areas that could do with being freed up around the front wing,” he said to Motorsport.com.

In recent years the look of F1 cars have change, most notably in 2017 with longer, wider looking cars and more aerodynamics for faster cars.

But the increase in aerodynamics made it harder for cars to follow closely and now with the new regulations the aero could make the car unstable.

“Aerodynamically it’s going to be quite unstable. I don’t think that’s a nice thing to have,” Green added.
