Fuel Economy Overview

The 2014 Mercedes-Benz SLK55 AMG achieves an EPA-estimated 22 MPG in combined city and highway driving, with 19 MPG in the city and 28 MPG on the highway. Powered by a 5.5L 8-cylinder engine paired with a automatic 7-spd, this two seaters features Rear-Wheel Drive drive.

In terms of environmental impact, the 2014 SLK55 AMG produces approximately 401 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 SLK55 AMG has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $3,150, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $5,000 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.
