2. Lay off the damn loud pedal
You’ve heard this one before about a million times, and you know what? It’s still true. Every time I see some moron in a Prius out accelerate me off a light I wish I had the legal right to pull him or her over, pry their eyes open Clockwork Orange-style and force them to watch Jeremy Clarkson getting better fuel economy in a BMW M3 than the Stig in a Prius. Even the worst fuel-sipping cars made will become gas guzzlers when you floor it. More acceleration requires more energy. Guess where your car gets its energy from.
3. And the brake
Obviously you'll have to stop at some point, but if you know you’re turning soon or there’s a sharp bend in the road, coast for a bit. There are two reasons for this. 1) all your brakes do is convert your forward momentum into heat energy, and even the best energy recovery systems don’t capture 90% of that energy. 2) if you don’t slow down for a turn you have to take it faster, which is not only fun, it means you don’t have to accelerate as much. Last year, I compared hypermiling in a hybrid to some seriously fun driving. After 100 miles, the difference was one freaking dollar’s worth of fuel.
