Spy photo of Kamui Kobayashi and his Sauber pit crew reviewing starting grid procedures in their prototype 2019 F1 car, which incorporates the fossil fuel-less "green as grass" engine formula.

The proposed successor to the turbocharged V-6 formula car must be built entirely from biodegradable recycleables. Prior to the podium ceremony, the top three cars will be pushed into
parc fermé, where they must be eaten by the pit crew. Finishing order shall be determined by the cars' combined "drive and dine" times.
Not pictured are the anti-CO2 exhalation masks pit crewmen will be required to wear for the duration of the race (but which may be removed while in
parc fermé for the car eating phase).
It is unclear whether their engine contract with Ferrari will extended through the 2019 season but Sauber are rumoured to be in negotiations with
Nestlé and
La vache qui rit, who allegedly are developing more easily digested powerplants.
