2001 Mustang GT Coupe (4.6L V8)
I average 21mpg on my daily commute which is 2/3 highway and 1/3 city. I don't really drive enough pure city miles to know but, I would imagine it is probably in the high teens. On the last long trip we took it averaged 24mpg on the highway.
1997 Honda VFR750F (749cc V4)
I bought this bike when gas prices were at their peak with the intention of using it for my daily commute. So far it has averaged 45mpg on my mixed city/highway commute.
