This is a 2005 Toyota Echo modified for high fuel efficiency. It has the stock 1.5 liter DOHC VVT-i engine, 5 speed manual and its rolling on the fory recommended tire size, Hankook Optimo H418 (P175/65 R14) with the OEM steel wheels and plastic hub caps.\r
\r
I once managed to get 512 miles on a single tank of fuel, consuming only 10.587 gallons, thats an impressive 48.6 MPG.\r
\r
My Lifetime Fuel Economy is 43 MPG, thats 33% over the EPA Rating. \r
\r
It has a belly pan aeromod made out of corrugated plastic (COROPLAST), a vacuum gauge and a Scan Gauge II\r
\r
It also has a modified cruise control that maintains a constant load, instead of speed, to keep the MPG steady.\r
\r
I also changed the oil viscosity to 10W-30 and increased the tire pressure to 40 PSI.\r
