Compare the cost to drive a gasoline-powered vehicle and an
electric vehicle. Both vehicles have the same body, so drag
co-efficient Cd = 0.3 and vehicle front cross-sectional area A� =
2.0 m2 are same. Both the vehicles are driven for one hour at a
speed of 70 mph. Assume that the gasoline vehicle powertrain has an
overall efficiency of 20% and the electric vehicle powertrain has
an efficiency of 60%. If the price of electricity is £0.10/kWh,
what gasoline price (£/gallon) would result in the same energy cost
as fuelling with electricity? (Take ρair = 1.2 kg/m3, ρgasoline =
750 kg/m3 , LHVgasoline = 44,510 kJ/kg)
