Using an average mpg of 21.5 mpg (if the average age of a car is 12 years), this comes to ~628 gallons of gas per year.
EPA uses 33.7 kWh per gallon for ~21,160 kWh in a year. Divide by 360 * 24 and you get 2.5 kW continuous, so it seems plausible.
EU numbers based on [1] come out to ~1 kW for driving?
