Is the 2006 Saab 9-3 Convertible good on gas?

At up to 21 MPG combined, the 2006 Saab 9-3 Convertible is worse than average for a Subcompact Cars — that class averages about 22.8 MPG across 5,756 EPA-tested versions, so it's on the thirsty side for its size.

Real-world MPG vs the EPA number

The EPA figures above come from a standardized dynamometer test, not the open road — real-world MPG typically runs a bit lower depending on your driving, climate and terrain. That's true of every car on this site, old or new.

This 2006 model was originally EPA-tested under the pre-2008 2-cycle method, which didn't account for highway speeds over 60 mph, air-conditioner use, or cold starts. When EPA overhauled the test for model year 2008, city ratings fell by about 12% and highway by about 8% on average industry-wide — and EPA retroactively adjusted every 1984-2007 rating to the stricter standard so old and new cars could be compared fairly. The MPG above is already on that modern scale — the window sticker on this car when it was new likely showed a higher, pre-2008-method number.

At today's AAA national average price — $4.68/gal for premium gas as of 2026-07-05 — the most efficient trim runs about $3,343/year (roughly $279/month, about $22.29 per 100 miles) at the EPA's assumed 15,000 miles/year, using an estimated 714 gallons a year. We don't estimate a cost-per-fill since exact tank size isn't in the public EPA dataset, but the per-100-mile figure scales to any tank. Current national average gas prices →

Where the EPA lists premium, that’s the fuel the maker specified for the mileage test — many such engines run on regular with slightly less power/MPG. Whether premium is required or just recommended is an owner’s-manual detail the EPA dataset omits, so we don’t guess it.
