I think the Red Bull wins are due to Red Bull teamwork, & more specifically Adrian Newey & Sebastian Vettel. The engines have never been the most powerful & the alternator has let both drivers down! Renault have some homework to do over the winter break!

Renault alternators by Magneti Marelli

As used in Lotus and Caterham cars as well, but they have not had nowhere near as many problems. On that basis it is likely that RBRs problems are related to its location and the surrounding bodywork which prevent it being cooled correctly. In other words, it is Newey's design which is causing the problems.

Fair comment mrfill re the Renault alternators manufactured by Magneti Marelli.

Re the cooling of the alternators, it could be argued a number of ways - the bodywork design does not leave enough room for cooling, or the alternators design does not fit in with the requirements of the bodywork, or the engine design places the alternator in a compromised position in relation to the bodywork. Either way Renault, Magneti Marelli and Red Bull will all have homework to do!

The failed Renault alternator is a Renault part it is not linked with the Italian supplier Magneti Marelli.
Overheating is the problem, we use various suppliers for the sub internals but we build the alternator so we are responsible for the integrity of the part (Rob White).
The alternator is shaft driven off the crankshaft sitting in between the water pump and the hydraulic pump, it weighs 750g, is 5cm in diameter by 7cm long, maximum running temperatures are 200 degrees C for the copper windings and 150 degrees C for the bearings.
Two of the four engine manufacturers use water cooling to cool the alternator, Renault uses air cooling.

Everyone should remember that Renault invented EVERYTHING associated with the modern F1 Engine, beginning with their introduction of turbocharging in 1977 at their inception into the sport.

Renault sports certainly contributed a lot with many firsts in F1 engine technology (engine making) but to say that Renaul invented everything associated with the modern F1 engine is stretching things too far and exposing a gross lack of technical knowlelge.

sunny. yeah. the current f1 engine probably owes more to cosworth than to renault.

re the alternators. again you are correct. the innards are provided by mm, but the casings etc are all pure renault. i did see somewhere that the precise problem area was in a bearing. not sure if that is correct or not, but overheating of a bearing could be causing the failure?

your post just popped up. do really believe that those who disagree would dare try to discuss a technical subject?

@Sunny "Overheating is the problem, we use various suppliers for the sub internals but we build the alternator so we are responsible for the integrity of the part (Rob White)."

We??????? So....you work for Renault Sunny? And while I am at it...could liquid nitrogen be used in some way to cool the alternator? Just a thought. Ed

Ok got it...You did not use quotes but did credit Rob White...my bad! :o
