I agree your idea is a sound one though, and if development of the electronic motors and batteries continues in the direction its going, it should be feasible.

The starter is definitely not 200hp, it's a 24V motor I doubt it is a tenth of that
I've looked all over the regulations and I haven't been able to find any mention of a minimum speed for KERS
I don't see why they couldn't start using KERS, in the first regulation drafts they were supposed to run pure
electric in the pitlane
The 2012 Toyota Le Man hybrid could do it https://www.youtube.com/watch?v=dTvWSKjySW4
I could see the self-start feature being a phenomenal benefit if a car happened to stall on-track after a spin, etc. In that event I'd think using the battery energy to restart the car would be much preferable to a car's race day coming to a premature end.NTS wrote:I'm not sure they will do this, since you would want the battery to be as charged as possible (or as charged as allowed by the rules) at the actual start. That means not discharging it unnecessary on the warmup lap or for starting the engine. Fuel doesn't have this downside, because you could just put in a bit more fuel that you burn off before the start with no negative effects on weight etc.
Either these lads had their Weetabix or the power required is considerably less than stated. Or the starters they use are hugely over powered in comparison to what is required. Ok old vid,different eng, but you get the idea.tuj wrote: I have heard, although I could be wrong, that the starter motors the teams use in the pits are around 200-250hp..

Track starting wasn't required, but it was necessary due to the electric pit-lane. I'm thinking now it's more a "want" in stead of a "need".WhiteBlue wrote:The 2014 regs were always designed for on track starting. I'd be surprised if they have eliminated the concept on the way.
