The 2016 Mercedes-Benz C300 4matic, with its 2.0L turbocharged engine, achieves a combined fuel economy rating of 27 MPG. It’s not the most fuel-efficient car, but it doesn’t try to be. The C300 4matic is designed for someone who wants a mix of luxury, performance, and all-weather handling more than ultimate efficiency. Buyers likely consider this fuel consumption part of owning a Mercedes-Benz.

City and highway performance

The EPA estimates rate the C300 4matic at 24 MPG in the city and 31 MPG on the highway. The city figure reflects the stop-and-go of city driving, where the engine works harder to accelerate. The highway MPG shows how efficiently the engine can cruise at steady speeds. The 7-speed automatic transmission helps by selecting the best gear for both performance and fuel economy. Drivers who spend most of their time in cities will likely see numbers closer to 24 MPG, while those with highway commutes should expect around 31 MPG. These numbers aren’t groundbreaking, but they are reasonable for a luxury sedan with all-wheel drive.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Mercedes-Benz C300 4matic at $2,150. This is based on 15,000 miles per year, a mix of city and highway driving, and the national average fuel price at the time. This figure is helpful for comparison, but remember that individual fuel costs change based on driving habits, location (fuel prices vary), and gasoline grade. While the C300 doesn’t require premium fuel, it’s recommended for the best performance and fuel economy, which can change annual costs.

Real-world expectations

EPA estimates are a baseline, but real-world fuel economy can vary. Aggressive driving, short trips, and heavy traffic all hurt fuel consumption. A number of owners report figures close to the EPA estimates, usually between 22 and 29 MPG in mixed driving. Factors like tire pressure, vehicle maintenance, and even the route influence the outcome. Consider these things when deciding if the C300’s fuel economy fits your driving.

How it compares

The 2016 C300 4matic’s fuel economy is competitive within its class. A 2016 BMW 328i xDrive, with its 2.0L turbo engine, gets about 26 MPG combined. The Audi A4 2.0T Quattro from the same year gets around 25 MPG combined. The Lexus IS 200t, while not all-wheel drive, offers similar luxury and a slightly better 26 MPG combined. These figures show that the C300 4matic’s fuel consumption is a reasonable tradeoff for what people see as advantages in styling, interior, and the Mercedes-Benz brand. Before deciding, drivers should review C300 MPG across all years to best understand the long-term effects of owning this vehicle.

Tips to maximize efficiency

The C300 4matic responds quickly, which can lead to fast driving, but try not to accelerate hard all the time. Accelerate gently and anticipate traffic to save fuel. Smooth driving is more efficient in any car, especially turbocharged engines because they react to throttle inputs.

Keep your tires inflated. Under-inflated tires increase rolling resistance, making the engine work harder and burn more fuel. Check your tire pressure often and keep it at the recommended level on the driver’s side door.

Avoid idling. If you’ll be stopped for more than a minute, turn off the engine. Modern engines restart quickly and efficiently, and idling wastes fuel. This is especially true in cities with stop-and-go traffic.

Use the “Eco” driving mode, if available. This mode usually reduces throttle response and sets the transmission for fuel efficiency. It can help in city driving, where fast acceleration isn’t always needed.

Regular maintenance is critical for fuel economy. Keep your engine tuned and air filters clean. Proper maintenance helps the C300 4matic’s performance, and its fuel efficiency. You can explore all Mercedes Benz fuel economy data on our site.
