Where it stands
Across every class it is 3rd of 5 plug-in hybrid models, in the upper half, ahead of 50% of the others.
A plug-in hybrid can run on its battery for a distance and then on fuel. The MPG, fuel cost and CO2 figures on this site are for running on fuel with the battery depleted, so a driver who charges often will use less fuel than shown.

At 15,000 miles a year with 55% of them in the city, with premium gasoline at $5.48 per gallon, the annual fuel bill of the most efficient version is about $3,050.
Tailpipe CO2 is 158 g/mile for the most efficient version.
