No, I disagree - the cost to develop a reasonable, scalable alternative fuel technology is astronomical. While I concur that there needs to be interest by manufacturers, there are few in the auto world that actually believe there is an alternative energy source to power cars in the immediate future. It's a fallacy - internal combustion will be around for a long time. There's a reason coal and oil remain at the top of the energy food chain. The EROEI is better than any other source, and the generators (e.g., engines) can be made small enough to power a vehicle. Hybrid is still at least partially internal combustion, but if they start tilting the rules towards more electric-based cars, it will be too expensive - at least in the LMP1 world given budget for all the other elements (aero, serviceability, etc) I'll agree with your point if we are talking Formula E, which is why Porsche is looking at it. Budgets are capped (I think it's $3.5M?) as opposed to the wild west $30M+ budgets of LMP1. If LMP1 is to be a viable formula, it's non-hybrid, limited aero, etc. They will fail otherwise.
