I saw an electric powered S-10 pickup on TV last week that did 12 secs in quarter mile with these litium batterys and other vehicles are starting to show up racing with electric mortors even faster. Why can't they use a towmotor electric motor with a transmission that will run for about 8 to 12 hours on a charged battery? Towmotors across the country do this everyday and they weigh a lot more than a car does.
