I've got no skin in the Renault/Red Bull/Lotus menage a trois. Just questioning the validity of a meaningful "real" advantage to an engine manufacturer since the regulations so heavily favor aero design.
It is indeed debatable. I mean as it is now, that
the customer teams get exactly
the same spec engine as
the factory teams do. I guess
the question is, will
the factory team get engine evolutions and so on before
the other teams? That was
the case in
the past, but i am not so sure it is as big a factor these days, because it is so competitive and
the suppliers surely won't want bad publicity from
the teams potentially blaming old engine evolutions for them being slow at a given circuit.
We certainly haven't heard of this situation since
the V8's started in 2006 which therefore tends to support that theory. There is no
realreason why a huge disparity (say 15-20hp) between customer and factory engines would suddenly appear in 2014 either, when one isn't present at
the moment.
Any performance gain from knowing
the engine dimensions early can easily be negated. Look at Brawn, that Mercedes engine was completely bodged into that car at
the last minute and it won both titles and 8 races in
the following season.
Thereal question is (somewhat obviously) who out of Ferrari, Mercedes and Renault will have
the best engine, and just as importantly, which teams will have
the best KERS systems. Although even this will only come into play at certain tracks like Spa and Monza,
the cars with
the most downforce will generally be quickest everywhere else.
