What you also have to remember is that for a team of this size, who are commited to the RRA and are racing because of the RRA, spending the required money on KERs which is believed to be around £5-6million would not be the best way of trying to catch up with the back of the grid.
Yes HRT are going to have williams old kers system but they are in the same boat as Marussia, they need to find seconds not 5 tenths.
I think this is a sensible move for the team, i just hope the designers can actually design a car that Glock can attack with rather than fight.
