Fuel Economy Overview

The 2017 BMW i8 achieves an EPA-estimated 28 MPG in combined city and highway driving, with 28 MPG in the city and 29 MPG on the highway. Powered by a 1.5L 3-cylinder turbocharged engine paired with a automatic 6-spd, this subcompact cars features All-Wheel Drive drive.

In terms of environmental impact, the 2017 i8 produces approximately 199 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this i8 performs better than the national average in this regard.

The estimated annual fuel cost for this vehicle is $2,450, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would spend $1,250 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.

Aerodynamic Speed Penalty

EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Expect your real-world highway fuel economy to drop by roughly 15-20% at interstate speeds.
