Sales of the Chevrolet Bolt EV ticked up a bit at 8,281 units during the first six months of 2018 despite its federal tax credit being cut from $7,500 to $3,750 on April 1. It’s worst sales month was, in fact, April, though sales have since rebounded as Chevy responded with generous cash rebates and cut-rate financing offers. By comparison, 7,858 Bolt EVs were sold during January-June 2018.
