TrueDelta Reviews the Real Gas Mileage of the Fiat 500L

Fiat 500L Real Gas Mileage: Pros
YearComment
2014 The FIAT 500L's EPA ratings--24 mpg city, 33 mpg highway--are about as good as you'll see in a small, conventionally propelled crossover. The Buick Encore does a touch better (25/33), but the MINI doesn't (23/30), and the Kia Soul scores considerably worse, at least on the highway (23/28). In real-world driving the 500L's trip computer reported averages around 30 in the suburbs (even 37 with a very light right foot) and about 35 on a 70-mph highway. Two caveats. Make a lot of use of the turbo, and fuel economy will plummet. And while premium fuel is not required, it is recommended. see full Fiat 500L review

The gas mileage is nothing to write home about, but it's nothing to scream and shout about either. It's about average for this size of car. I'm seeing the upper 20s so far in a mix of city and highway driving. Fiat recommends premium unleaded, but it does run fine on regular unleaded. see full Fiat 500L review

clearly AMG was not thinking gas mileage at all when they built this engine see full Mercedes-Benz SLK review
