It looks pretty good. I guess the important thing is for the word "electric" to be really obvious so that spectators notice.
Since it runs on electricity, it's very hard to directly compare the energy efficiency of the Focus electric to traditional gasoline cars, but the closest thing we have is the MPG-equivalent metric:
"Focus Electric is America’s most fuel-efficient five-seat car that offers the equivalent of 110 miles per gallon (MPGe) city, 99 MPGe highway and operates entirely on battery-generated power. Focus Electric has been certified by the U.S. Environmental Protection Agency to offer 105 MPGe combined."
