Is nuvinci CVP a good option?

Will the vehicle actually be operated on public roads,with all the attendant traffic,idling,acceleration,deceleration,yields,st ops,traffic lights,gridlock,curves,turns,parking,warm re-starts,cold re-starts,etc.?
Is 100 kg you all-up weight,including driver?
For all the transient loads,you'll need to keep the engine in it's peak BSFC island.12-speeds is equivalent to a CVT according to SAE research.
For a steady-state economy cruise you'd want a fully-locked,1:1 output(no overdrive)with a traction tire diameter which would yield the ideal 'gearing.'
Sprocket and chain drive has been used to good effect with some previous record cars.Very high mechanical efficiency.
