An electric dragster is a drag racing vehicle which contains an electric propulsion system which is powered by batteries, fuel cells, supercapacitors (ultracapacitors), and sometimes they include a combustion engine to recharge their ESS (Energy Storage Systems).
They are being considered as replacements for gasoline and diesel powered vehicles for many reasons, including the high efficiency of electric motors, their reliability, as well as their torque curves which can be achieved without a costly transmission.
Batteries and supercapacitors especially have relatively low energy densities compared to liquid fuels such as gasoline.
Associated increases in mass can result in slower acceleration when compared to a gasoline-powered vehicle with similar power and weight characteristics.
Offsetting these disadvantages is the benefit that batteries in an electric dragster can be evenly placed along the floor to keep the centre of mass low.
