From the prototypes I have seen, they are not. The fronts look the same as the Euro S2 (I did not measure them) but the rear hubs are different. The rear wheels on the prototype were wheels off the VX220 (whatever it's called), S2 wheels would not fit.

I'd wait a few weeks until Lotus gets in the next batch of Federal Elises before ordering any wheels
