I am new to all of this, so here goes
I have a 2007 Yaris that I have modified for better fuel economy, the first thing I did was to fabricate and install a 3 peace aluminum underbody that is 36" wide by 48" long each. The next thing was 10% under drive aluminum pullies, then a high flow muffler, then an upper grill cover and moon hubcaps.The tires are set at 44 psi, and I have a scan gauge II for monitoring. The most recent thing I have tried is a hot intake air system that take air from above the exhaust header and ducts it to the air filter box. all this has got the Yaris down to 4.3L/100 km 56 mpg US with the air intake temp at over 60C 140F, 60% highway/ 40% city. I use my cruise control a lot set at 90 km/hr 55 mph and coast down long hills in neutral with engine at idle and do a lot of coasting up to stop lights...
