2012 Mercedes-Benz CLS550
Fuel Economy Overview
The 2012 Mercedes-Benz CLS550 achieves an EPA-estimated 20 MPG in combined city and highway driving, with 17 MPG in the city and 25 MPG on the highway. Powered by a 4.7L 8-cylinder turbocharged engine paired with a automatic 7-spd, this compact cars features Rear-Wheel Drive drive.
In terms of environmental impact, the 2012 CLS550 produces approximately 444 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 CLS550 has higher-than-average emissions in this regard.
The estimated annual fuel cost for this vehicle is $3,450, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $6,500 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.

Adjust the slider to match your daily driving habits. City driving involves stop-and-go traffic under 45mph, while highway driving represents sustained speeds over 55mph.
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.

Mercedes-Benz is recalling certain model year 2012 CLS550 and CLS550 4Matic vehicles, manufactured December 01, 2011, through December 13, 2011. The bolts that hold the hood's secondary latch striker may have been insufficiently tightened.
Consequence & Remedy
Consequence: The reduced torque of the striker bolts might lead to a loosening of the bolts. If two of the four bolts securing the striker became loose, the secondary hood latch function would become ineffective. If this problem combines with a failure of the primary hood lock or if the hood is not properly closed, the hood could open while driving, increasing the risk of a vehicle crash.
Remedy: Mercedes-Benz will notify owners, and dealers will check and retighten the bolts as necessary. Mercedes-Benz notified the owners by phone for this campaign starting on 11/21/2012. Owners may contact Mercedes-Benz at 1-800-367-6372.
