Although GM will not produce a "sposts" model of the Bolt EV, that doesn't mean a third party will offer a version. Just like Saleen updates the Ford Mustang and Callaway updates the Corvette and Camaro, someone will do the same for electric cars. But it may not be as cost effective as one may believe. By the same reason, someone may think up a way to make the battery swappable, so they can set up swap stations along superhighways and for several dollars you can get another 50 kWh in minutes.
One idea for a drag racer is to remove a big part of the battery and leave about 1 kWh or less, just enough to roll toward the track and out. Then add several kWhs of supercapacitors and rebuild the controller (and motor if possible) to pull over 300 kW of immediate power, enough for several seconds of a race. The battery removal will lighten up the Bolt EV and with that immediate power it can run faster than many gassers.
Supercaps are light for the power they handle, but each can supply hundres of amps and tens of thousands of watts in seconds, more than what any battery can!
