This car did not represent the literal term of ‘smog’, but it was part of the smog-era’s timeframe. In 1980, Bradley Automotive introduced an all electric sports car called the GTE. Moving it down the road was a 20.7 horsepower motor. Backing the motor were 20 six volt lead acid batteries, plus a single 12 volt unit for the vehicle lights, wipers, radio, etc.
It was quite a bit heavier than the Beetle it was based on— it’s weight nearly 3000lbs. Top speed was 75mph and zero to thirty miles per hour took 8 seconds. The GTE was built to almost the end of the smog-era, 1982.
