At the launch of it's new SF90 at Maranello on Friday, the Italian outfit revealed a new darker matte colour, having moved away from its traditional gloss finish.
But rather than this having been done to simply make the car look better, team principal Mattia Binotto says that the inspiration for the move was to help reduce the car weight – as the matte finish weighs less.
"The reason is not aesthetic, but exclusively technical," explained Binotto. "Eliminating the shiny element gives us a few hundred grammes, which may not sound like much, but when you push everything to the limit even this has an effect."

If you watched the Rolex 24 you saw that the Porsche GTLM cars were wrapped, not painted. The vinyl wrap was damaged on the nose of the car #911. Again this was said to be done as a weight savings over painting the cars.
