Originally converted as a 120 Volt car with flooded batteries filling the back seat area. Measured range was over 40 miles and the performance was quite good. Replacing the 10 large 60 pound 27-TMHs with 16 of the little 45 pound Optimas drastically improved both the performance and range while making the back seat once more available. The car now actually has more storage space than when it was an ICE! Other features include JVC CD deck with 8" sub and aluminum EMPI 8 spoke wheels.
