26 MPG combined won’t make headlines, but it’s respectable for the 2016 BMW 428i xDrive Gran Coupe. This car appeals to drivers who prioritize style, performance, and all-weather confidence, and are willing to accept slightly above-average fuel costs.

City and highway performance

The EPA estimates 22 MPG in city driving and 33 MPG on the highway for the 2016 428i xDrive Gran Coupe. The city figure reflects stop-and-go traffic, where the 2.0L turbocharged four-cylinder engine works harder and the automatic transmission shifts often. The highway number showcases the engine’s efficiency when cruising. While 33 MPG is possible on the open road, aggressive driving or speeding will lower that number. These figures use standardized EPA tests, which don’t account for specific driving conditions.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 BMW 428i xDrive Gran Coupe at $2,250. This is based on 15,000 miles per year and national average fuel prices. Actual fuel costs vary depending on driving habits, local fuel prices, and fuel type. Premium fuel is recommended for optimal performance, which could impact your actual cost.

Real-world expectations

EPA estimates provide a baseline, but real-world MPG can vary for the 2016 428i xDrive Gran Coupe. Drivers who accelerate quickly or frequently drive in congested cities might see figures closer to the low 20s. However, those who prioritize fuel efficiency and spend more time on the highway could exceed the EPA’s 33 MPG estimate. Hilly or mountainous terrain will likely decrease fuel economy. The xDrive all-wheel-drive system adds weight and uses energy, which has a minor impact on MPG.

How it compares

The Audi A5 Sportback Quattro, a key rival, achieves a similar 25 MPG combined. You can learn more about all Bmw fuel economy data here. The Mercedes-Benz C300 4MATIC sedan posts EPA estimates of 24 MPG combined. While BMW’s 428I edges out the C300 slightly, the differences are small. The Acura TLX SH-AWD achieves 25 MPG combined, offering a slight improvement in fuel efficiency. For many drivers considering the 428I Gran Coupe, fuel economy isn’t the main concern, as performance and styling are the more important factors.

Tips to Maximize Efficiency

Avoid aggressive acceleration and braking. The 428i xDrive’s turbocharged engine delivers plenty of power, but using it excessively will drastically reduce fuel economy. Gentle acceleration and anticipation of traffic flow can significantly improve your MPG.

Use the Eco Pro driving mode when possible. This mode optimizes engine and transmission settings for maximum fuel efficiency, and it may slightly reduce throttle response, but it’s a worthwhile trade-off when fuel economy is a priority. Good driving habits are still essential.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which can negatively impact fuel economy. Check your tire pressure regularly and inflate them to the recommended level specified on the door jamb.

Minimize idling. Idling wastes fuel and contributes to emissions, so if you’re stopped for more than a minute or two, it’s more efficient to turn off the engine.

Keep up with regular maintenance. A well-maintained engine runs more efficiently, and you should follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug replacements.
