In previous KERS usage, it appeared that the McLaren KERS was the technically and packaging superior solution, very small and light, possibly the most efficient.
Who makes and supplies KERS to teams not using McLaren's solutions and how do they compare packaging/size and weight wise?
How do the various KERS vary, technically?
What sort of packaging/placement (CG and cooling) variations are the teams using?
Thanks!
PS: Have not seen if all teams will be using KERS either?
