2010 4dr Sedan turbocharged 211hp 2.0L I4
6-speed manual AWD
Better than expected highway mileage. Averaged 34mpg on a 350-mile trip last weekend, keeping speed to about 60mph. Commuting mileage is acceptable.
2010 4dr Sedan supercharged 333hp 3.0L V6
7-speed automated manual AWD
27mpg at 70mph
2009 4dr Sedan turbocharged 211hp 2.0L I4

30mpg is easy to achieve with modest driving, even with the turbo.
2008 4dr Wagon turbocharged 200hp 2.0L I4
6-speed shiftable automatic AWD
Good tradeoff of performance and mileage. Previous VW 1.8t owner, viewed this as an upgrade.
2008 4dr Sedan 420-horsepower 4.2L V8
6-speed manual AWD
EPA ratings are accurate. I've seen as low as 12 mpg in the city, and up to 22 mpg on highway journies. I average 15 mpg in mostly-city driving.
2008 4dr Sedan turbocharged 200hp 2.0L I4
6-speed manual AWD
Great fuel economy if driven easily, but is a great performer if pushed. Best of both worlds.
2008 4dr Sedan turbocharged 200hp 2.0L I4

2010 4dr Sedan turbocharged 211hp 2.0L I4
6-speed shiftable automatic AWD
Quattro and turbocharged engine form a thirsty combination. I would have expected 700+ highway kms but typically get only 600.
2010 4dr Sedan supercharged 333hp 3.0L V6
7-speed automated manual AWD
Avg about 18-20 mpg on real world highways. City can be as poor as 12-14.
2008 4dr Sedan turbocharged 200hp 2.0L I4
6-speed manual AWD
The diesel version has MORE torque and power AND has a far better range (about 700 miles for 2L diesel engine), I dislike the 22-24 mpg for the combined driving (mostly city). Those are still good numbers for its class. Sucks when have to pay $3.87/gallon
2008 2dr Convertible 420-horsepower 4.2L V8
6-speed manual AWD
No 420hp car is going to sip fuel, but the fuel tank is small (14.5 gallons) and thus needs filled too often.
