9. 2006 Scion xA (four-speed automatic transmission) – 30 MPG Combined
Leading the xB in petroleum frugality is another Scion model, the sexually confused xA. This small car is an amorphous-looking hatchback with androgynous design cues. Can you determine a gender? It somewhat resembles a partially risen dinner roll, but it’s far more lopsided and a lot less golden brown.
Featuring the same 1.5-liter four-banger/four-speed automatic combination found in the xB this car actually delivers slightly better fuel economy. It nets 27 miles to a gallon in urban conditions and up to 35 on the interstate. Dorkiness must trump boxiness when it comes to aerodynamics because combined fuel economy is 30 MPG. At the end of the day Scion’s xA was so good the company doesn’t even offer it any more.
