F1: Bottas to take grid penalty at COTA

Valtteri Bottas will take a 5-place grid penalty on Sunday after Mercedes is giving him his 6th Internal Combustion engine for the year, whereas only 3 are allowed per year.

It appears that Mercedes is using Bottas as a sacrificial lamb to test new engine bits for more power.  When they get it right, then Lewis Hamilton will get the more powerful engine.

Sebastian Vettel and George Russell are also getting new Mercedes engine this weekend.
