Are Mercedes taking a risk by not completely replacing Hamilton's engine?
Where Max Verstappen changed his complete engine for a new one in Russia, Lewis Hamilton only changed the ICE (Internal Combustion Engine) in Turkey. That did earn him a grid penalty of ten spots, but with a completely new engine he doesn't drive, unlike Red Bull Racing's Dutchman. Why didn't Mercedes replace the entire engine of the title contender, just like Red Bull did?
