Tests performed by Ford Motor Company and Pro Formance drivers found that 48 motorists coached by eco-driving experts saw results ranging from 6% fuel economy improvement to more than 50%, depending on their driving style and ability to master eco-driving behaviors. The average fuel economy improvement was 24%.I think that would be a good idea for the US to incorporate eco-driving into standard drivers ed. I read about another country doing this (Sweden maybe?) but I am drawing a blank at the moment as to who that was.
Eco-driving instructors coached drivers to employ smoother breaking and accelerating, monitor their RPMs and drive at a moderate speed. Among the eco-driving practices that drivers can begin practicing on their own are driving 55 mph instead of 65 mph, keeping tires properly inflated at the recommended pressure, and eliminating prolonged idling.
Hands-on instruction is critical for achieving full potential of eco-driving since instructions for eco-driving techniques must be customized after instructors have had the opportunity to observe individual driving habits and then provide coaching for more fuel efficient driving techniques, Ford says.
The US consumes close to 150 billion gallons of gasoline annually, according to the US Energy Information Administration. If every American practiced eco-driving and got the EPA-estimated 15% benefit in fuel economy, more than 22 billion gallons of gas would be saved.
