While $77,000 is a lot of money for a car, it isn’t too much for a sophisticated midsize sedan with a classy, understated cabin, plenty of power, and world-class handling. For folks in the Snow Belt, the addition of an AWD base car to the lineup is a big deal. Be aware that options quickly inflate the bottom line of this, or any, BMW. And to quell any doubts, though electric, the i5 is a fine driving machine, and a worthy model in the 5-Series lineup.
