Do you remember a list we published with the 10 most fuel-efficient domestic cars? Here's a new one we'd add if we redid the list today: the Pontiac G3. The G3 reminds us of a previous post about Pontiac's deteriorating brand identity. Based on the Chevrolet Aveo, the G3 will spot the same 1.6-liter engine found in its siblings. The G3 is certified as a 2009 model and, like the Aveo, it's rated at 25 mpg city and 34 highway, which improves the Pontiac Vibe's 28 mpg average (55 percent city/45 percent highway, all in U.S. gallons) Pontiac sells the current version of the G3 in Canada, where it is called the Wave, and in Mexico.
