the Tesla Roadster is another bullshit in action (claiming 300hp, with a ~50kWh (a bit suspect even here, given that a Prius has a battery capacity of ~1kWh) battery and a range of some 250 miles? 300hp is about 200kW, if the roadster is traveling 200mph, 50kWh gives you about 1/4h run time, which equals about 50 miles...bullshit claims QED).
Name a single car that gets its advertised city/highway mileage while operating at 100% output or 200mph. Either one will do.
