Why have holes at bumper? Lighter? Faster?

You may laugh at the idea of ground effect but F1 Lotus was the one who discovered its advantage. Its F1 car lap faster than other F1 cars back in the day.

It has evolved from side curtains to air diffusers that we see now.

For the full ground effect the underside of the car has to be fully covered with the splitters or diffuser (the fins between the 2 exhaust pipes) at the rear.

This is an example.The rear vent is a long rectangular hole which looks subtle and aesthetically pleasing. See just below the license plate. What the vent does is to let trapped air escape.

The Vios' diffuser dont do anything. It is just for show. I doubt the underside of the Vios is covered.

 

rear diffuser needs a sealed and flat underbody to work properly

otherwise it is just ornamental

Planning to murder his rear passenger, reduce the safety from bumper.

Even without the holes this version of Vios rear bumper already fully caved in when I saw it was rear ended by a SUV.

The SUV front bumper only slightly scratched.

Wanted some free coasters for his dining table. 😂

Maybe to counter the weight of the Surbo he installed?
