I'm having difficulty hypermiling an Xterra 2012. I can't seem to get much above the EPA ratings. IIRC, it should be 16 MPG city, 22 MPG highway. My reported MPG should be between 18-19 MPG city and 23-24 MPG highway. Terrain: Suburban, around a mid-sized city. Large roads are marked 45 MPH, some roads are marked 50 MPH, interstates are 70 MPH. Residential is marked 35 MPH. Techniques used: -Drive on half torque peak, because when looking at similar engines to what I have (I can't find the BSFC map for it), peak fuel efficiency usually occurs at half torque peak for gasoline engines. -Pulse and coast; I hover between 5 mpg of either speed limit -2.5 or the speed limit itself. -Timing traffic lights. If the light in front of me is red, I immediately take my pedal off the gas, and depending on the stop light distance, I either cut 20 mpg immediately off speed, wait a little, or hope that by the time I reach the back of the vehicle in front the light will have changed. -Usually speed limit speed driving. On a 70 MPH highway, I will usually do 70 MPH on cruise control, because pulse and coast on 5 mpg for hours is usually too tiring. -Turning off the engine at stop lights. I turn off the engine, switch to neutral, and get ready to restart and bump-start the car. -Wheel inflation. I try to keep the inflation up at about 110% of manufacturer specifications. It should be 45 PSI (iirc), it's set to 50 PSI. -Coast to stop. If I have a stop sign in front of me, or I need to drop to 0 speed, I just coast the vehicle on automatic drive, then brake sharply as I approach the stop. Techniques tried, then abandoned: -Driving on 2500 RPM or even 3000 RPM. The theory is that at higher throttle, the car should have greater fuel efficiency, but observing gas station receipts I don't get much out of it. Perhaps I'm wrong? -Pulse and coast in neutral. Illegal, probably damages the engine and wears out the ignition switch. Not doing it anymore. Stuff I won't try: -Drafting. Sounds cool, not putting up with the danger. -Car mods. This isn't my car, I'm not going to bother taking off the roof track to reduce aerodynamic drag. My problem: As you can see, I'm getting between 15% and 5% improvements on MPG compared to EPA fuel economy estimates. As someone who intends to hypermile, what am I doing wrong? For instance, should I do 10 mile pulse and coast? IIRC, it's annoying as hell to the driver behind me, although I can't honestly say that I am a good driver.
