8. Lexus GS450h (31 MPG Combined)
Another Lexus makes the list, this time it’s the GS450h sport sedan. Using the same powertrain as the RX450h, the GS manages to make 338 horsepower, and can blast to 60 mph in 5.6 seconds. This rear-wheel drive Lexus is still fun to drive and manages to get 31 mpg combined, making it frugal and exciting. The $59,450 is a bit steep, but at least you won’t have to pay much more in fuel.
