The Art of Bore
Merc engine has more power when new but the power falls off more than other engines when the unit is old... not sure how many power units mclaren have used?That's what I thought - but that doesn't explain why McLaren are dropping off, or why Ricciardo's performances aren't improving. If indeed that's both true.
There's also a lot of money involved in getting a good position in the constructors standings, isn't there?
Edit ricciardo took his 4th engine and a penalty on 10th October
So has done Turkey, USA, Mexico, Brazil, Qatar and Saudi on that engine... so perhaps that explains a bit of it
