Capacitors in EV to change power-energy balance of a battery?

Say I was building an EV that required performance over range. Eg 80km range when driving nicely but the capacity for several hundred horsepower for no more than about 10-12 seconds.

Is it feasible to install cheap batteries to get the voltage up, in parallel with capacitors to provide huge short term current draw capacity?

Would it be any better than equivalent cost and weight in more batteries?
