On behalf of Mitsubishi Switzerland I hypermiled the 5-speed stickshift Mirage (1.2 litre gasoline engine / 'Space Star' in Europe) thru Switzerland and Austria (via 5900 ft Arlbergpass) to Salzburg and back in spring 2013. Covering 1112 kilometers (> 691 miles) with less than one tank resulted in 69.6 mpg (USG!) or 3.38 litres/100 kms (that Space Star is rated 57.4 mpg based on the NEDC). It's the most economic non hybrid gasoline vehicle I tested so far. The car does better mileage on rural roads in the 35 to 45 mph speed range than it does on the tollway at a constant 55 mph...
