- '20 CX-5 Signature
Fuel economy is not one of the CX-5's best attributes. I've been averaging just under the combined EPA rating of 24 in my '20 Signature.Worried about fuel economy.
Have 2017 CX5 GT and fuel economy is quite poor.
According to Fuelly.com:
"Based on data from 65 vehicles, 1,965 fuel-ups and 518,335 miles of driving, the 2019 Mazda CX-5 gets a combined Avg MPG of 25.11 with a 0.18 MPG margin of error." (2.5L non-turbo FWD & AWD)
"Based on data from 41 vehicles, 1,292 fuel-ups and 333,187 miles of driving, the 2019 Mazda CX-5 gets a combined Avg MPG of 24.71 with a 0.21 MPG margin of error." (2.5L turbo AWD)
So, there doesn't appear to be much real-world fuel economy disadvantage in exchange for the turbocharged engined and AWD.
For the 2017 CX-5, Fuelly.com reports:
"Based on data from 153 vehicles, 8,977 fuel-ups and 2,429,353 miles of driving, the 2017 Mazda CX-5 gets a combined Avg MPG of 24.95 with a 0.08 MPG margin of error."
So, unless there's something wrong with your 2017 CX-5 resulting in what you consider to be "quite poor" fuel economy, it's likely that a 2020 turbo or non-turbo would return similarly "quite poor" fuel economy.
