when u are trying to lower your electrical load so you can run without an alternator then 24w total draw instead of 110w draw from your headlamps is a major accomplishment. (alternator delete= 8-10% increase in mileage)
converting a car to ALL led's is the first step.
disabling the alternator and putting a 100amp hour battery in your trunk is the second.
lowering your aero drag from .32 to .29 is the next. (very achievable)
then you hook up a relay on the brake pedal so your alternator will charge when you are on the brake to extend battery life a little (or will provide for a bit less on the overnight charging when back at home)
Doing just the alternator mods will raise fuel efficiency by like 8-10%. add the aero mods and your even higher, a total of 13-15% wouldn't surprise me.
