This idea of an engine being completely free to develop, with only the amount of fuel you can use being a limiting factor is perhaps the best idea that the ACO has had, ever. Talk about creativity, the engine possibilities are endless, and better still, it pushes manufacturers to make high performance, high power/torque “eco” engines.
I know there will be three manufacturers (at least) at the front in 2014; Audi, Toyota, and Porsche. But I’m not so sure F1 teams will be so quick to jump on this. Think about it, how economical is an F1 engine (in terms of fuel use)? It probably wouldn’t stand a chance against the specially designed Diesel/Petrol Hybrids that were made for the LM24. Still, cool idea, and maybe it will lure in some of the bigger teams in, possibly a few from F1. But if the F1 teams do join, I’m sure they won’t be using their F1 engines.
