Depends on the type of motor used.
Actually turbine-electric makes some sense: turbines are efficient at
constant speed and offer both high efficiency and light weight,
offsetting the heavy batteries. Regeneration is unnecessary in a
constant--power setup: the turbine expanders can be optimized for that
regime.
Emissions would be a deal killer because it would take intense and
long development to get them to recip standards. The best thing that
could be done for turbine car buffs would be to enact a emissions
_certificatiion_ waiver for turbine cars for a set time, so as to make
it worthwhile for some company to build a fair run of them. The waiver
should be carefully written to force the outright sale, not lease or
test loan, of the cars so they cannot destroy them like the Chrysler TC
program or the GM and Ford factory electrics.
