27 MPG combined isn’t going to win any awards, but it’s an acceptable figure for the 2016 BMW 428i Coupe. This isn’t a hybrid striving for maximum mileage, it’s a stylish two-door coupe designed for drivers who prioritize performance and a sporty driving experience. Fuel economy is a consideration, of course, but secondary to the thrill of the road and the prestige of the badge.
City and highway performance
The 428i’s EPA estimates are 23 MPG in the city and 35 MPG on the highway. That highway number is particularly relevant, as many 428i owners use their cars for longer commutes and weekend road trips. The turbocharged 2.0L engine provides ample power for effortless highway cruising, and the eight-speed automatic transmission helps keep the revs low, maximizing fuel efficiency at higher speeds. The city MPG reflects the reality of stop-and-go traffic, even there, the 428i’s engine start-stop system helps to conserve fuel while idling.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2016 BMW 428i Coupe at $2,150. This figure is based on driving 15,000 miles per year and using national average fuel prices. Fuel prices fluctuate, and your actual costs will depend on your driving habits, where you live, and the type of fuel you use. This makes the $2,150 a benchmark for you to compare all Bmw fuel economy data to each other, or to rival vehicles.
Real-world expectations
While the EPA estimates provide a useful baseline, real-world fuel economy can vary, so you can often expect to see slightly different numbers. Aggressive driving, frequent short trips, and the use of accessories like air conditioning can all impact fuel consumption. However, a conscientious driver who uses the car’s Eco Pro mode and avoids heavy acceleration can often match or even exceed the EPA’s highway estimate. Exploring 428I MPG across all years can illustrate the variance in real-world mileage from year to year.
How it compares
Compared to its competitors, the 2016 BMW 428i’s fuel economy is generally similar to other sport coupes. The Audi A5 Coupe, with its 2.0L turbocharged engine and Quattro all-wheel drive, achieves around 25 MPG combined. The Mercedes-Benz C300 Coupe, another popular competitor, also returns around 25 MPG combined. The Infiniti Q60, known for its powerful V6 engine, sacrifices fuel economy to deliver more performance, achieving around 22 MPG combined. For buyers prioritizing fuel efficiency, the Lexus RC 300h hybrid achieves superior efficiency. Most buyers in this segment cross-shop several sport coupes before making a decision.
Tips to maximize efficiency
The driving mode selector has a tangible effect on fuel economy. Selecting “Eco Pro” mode optimizes the engine and transmission settings for maximum efficiency. The accelerator becomes less sensitive, and the transmission shifts earlier, helping to minimize fuel consumption. This mode is particularly useful for highway driving and bumper-to-bumper traffic.
Proper tire inflation plays a critical role in fuel efficiency. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check your tire pressure regularly and inflate them to the manufacturer’s recommended levels, which can be found on a sticker inside the driver’s side doorjamb.
Reduce unnecessary weight in the vehicle. Extra cargo in the trunk adds to the vehicle’s overall weight, which reduces fuel efficiency. Remove any unnecessary items from the trunk and passenger compartment to minimize weight and improve mileage. This is helpful in city driving where the vehicle is frequently accelerating and decelerating.
Consider the use of premium fuel. While the 2016 428i doesn’t require premium fuel, using it can sometimes improve performance and fuel economy, particularly under heavy load or during spirited driving. Experiment with different fuel grades to see if you notice a difference and if the price increase is worth the potential benefits.
