TrueDelta Reviews the Real Gas Mileage of the BMW X1

BMW X1 Real Gas Mileage: Pros
YearComment
2016 Fuel economy was a "why to buy" with the original BMW X1. Probably owing to its additional height, in the EPA's tests the new X1 rates one mpg lower on the highway but the same in the city, for a still very competitive 22 city / 32 highway. These are good numbers for a quick all-wheel-drive (AWD) crossover with plenty of room for four people and their stuff. Though smaller and less powerful, the Audi Q3 scores lower, 20/28. The Mini Clubman, with the same engine and transmission but without AWD and with less weight and frontal area to push through the atmosphere scores a little better, 24/34. Within the class only the Mercedes-Benz GLA does better, and then only in city driving (24/32). In my driving the X1's trip computer ususally reported suburban averages around 26 mpg, but as low as 23 in harder driving and as high as 31 when driven in what I call "Prius mode." On a 70-mph highway the trip computer reported a two-way average just over 30. These numbers are a little better than those I observed in the old X1. see full BMW X1 review

Porsche Cayman Real Gas Mileage: Pros
YearBody/PowertrainComment
2008 2dr Hatch 295-horsepower 3.4L H6
6-speed manual RWD		 It is better than I expected. I average roughly 23 miles with city and highway commuting on days I choose to take it to the office. On trips I can get 26 mpg, not stellar but not awful. see full Porsche Cayman review
2008 2dr Hatch 295-horsepower 3.4L H6
6-speed manual RWD		 Fuel economy is reasonable relative to the car's performance - 20 mpg, plus or minus a couple depending on the balance of city versus highway driving. see full Porsche Cayman review

2007 2dr Hatch 295-horsepower 3.4L H6
6-speed manual RWD		 It sucks if you are driving the car correctly. On the slab I can see 26 mpg. see full Porsche Cayman review
