The 2016 BMW 428i Gran Coupe, with its 2.0L 4-cylinder engine, achieves a combined fuel economy of 27 MPG, a figure that reflects a blend of performance and practicality for buyers prioritizing style and driving experience over pure efficiency. This isn’t a hybrid designed for maximum mileage, it’s a sleek four-door coupe designed to offer a connected driving experience with reasonable running costs.

City and highway performance

The EPA estimates the 428i Gran Coupe achieves 23 MPG in the city and 34 MPG on the highway. The city figure accurately reflects the demands placed on the turbocharged engine in stop-and-go traffic, where frequent acceleration and idling affect fuel consumption. The highway number, however, is where the 428i Gran Coupe excels. Its smooth-shifting eight-speed automatic transmission allows the engine to cruise comfortably at low RPMs, maximizing fuel economy on longer journeys. Drivers covering high miles on the highway will certainly see the benefits, offsetting the less impressive city performance.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2016 BMW 428i Gran Coupe is $2,150. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a useful benchmark, but individual fuel costs will fluctuate depending on driving habits, local fuel prices, and the grade of gasoline used. Premium fuel is recommended for optimal performance, potentially increasing the annual fuel expenditure for some owners.

Real-world expectations

While the EPA provides standardized testing, real-world fuel economy can vary. Aggressive driving, frequent short trips, and consistent use of the Sport driving mode will reduce MPG. Conversely, a conscious effort to drive smoothly, anticipate traffic flow, and use the Eco Pro mode can help drivers achieve figures closer to, or even slightly above, the EPA estimates. Weather conditions also play a role. Cold starts in winter will reduce fuel economy due to increased engine load, while frequent use of air conditioning in summer places additional strain on the engine.

How it compares

When considering the competition, the 428i Gran Coupe’s fuel economy is competitive. The Audi A5 Sportback, another stylish four-door coupe, achieves a similar 25 MPG combined with its 2.0L turbo engine. The Mercedes-Benz C300 sedan, while not a direct competitor in terms of body style, manages around 28 MPG combined with its 2.0L turbo. Considering all Bmw fuel economy data, the 428i Gran Coupe sits comfortably within the range for BMW’s smaller gasoline-powered models. A prospective buyer might be cross-shopping the 428i Gran Coupe against a smaller, more efficient sedan, but the BMW’s unique styling and sporting character often outweigh minor MPG differences for its target demographic. If you are interested in models across the same years, you can find more data on 428I MPG across all years.

Tips to maximize efficiency

The 428i Gran Coupe’s driving mode selector offers Eco Pro, Comfort, and Sport settings. For daily commuting, Eco Pro mode should be the default, as it optimizes throttle response and shift points for maximum fuel efficiency. It can feel somewhat sluggish at times, but adapting your driving style will yield noticeable benefits.

Regular maintenance is key. Ensure the tires are properly inflated to the recommended pressure, as underinflated tires increase rolling resistance and reduce fuel economy. Schedule regular oil changes and air filter replacements to keep the engine running smoothly and efficiently.

Avoid unnecessary idling. If you’re stopped for more than a minute, turn off the engine. Modern cars are designed to restart quickly and efficiently, so minimizing idling time will contribute to less gas consumption. This is particularly relevant in urban environments with frequent stoplights and traffic congestion.

Gentle acceleration and smooth braking techniques can significantly improve MPG. Avoid jackrabbit starts and hard braking, anticipating traffic flow and maintaining a consistent speed. The less aggressively you drive, the less fuel you’ll consume.

Consider the weight you’re carrying. Remove any unnecessary items from the car’s trunk, as extra weight reduces fuel economy. While the impact might seem minimal, every little bit helps in maximizing efficiency over the long term.
