There's not a single thing about the Saturn Vue Green Line that makes it fun to drive. Most hybrids, at the very least, have a fuel economy/power assist computer that presents a challenge in maximizing fuel economy – but not the Vue. Reset the trip odometer and crunch numbers on a calculator to find out what your real-world fuel economy is. We managed just 22.6 mpg, a little short of the EPA rating of 27 in the city and 32 on the highway.
