Saab 9-3 2.0 liter*
Mileage: 22 mpg combined city/highway
Starting price: $28,385
The turbocharged, 2.0-liter four-cylinder engine in the 2007 Saab 9-3 sedan generates 210 hp, which is potent for a four-cylinder, although gas mileage is less than what a nonturbo engine would get. The standard transmission is a six-speed manual; a five-speed automatic is optional.
