The 2017 Alfa Romeo Giulia and Giulia Ti models are rated by the EPA at a fairly thrifty 24 mpg city, 33 highway, 27 combined. Opt for all-wheel drive and that falls to 23/31/26 mpg.
These volume models earn the Giulia a 7 out of 10 rating for fuel economy. (Read more about how we rate cars.)
Go for the 505-horsepower Giulia Quadrifoglio and fuel economy predictably suffers. This twin-turbocharged V-6 drops the fuel economy to 17/24/20 mpg. Two of our testers got 20 or more mpg, though with quite a few highway miles.
