23 MPG combined might not sound like much in the age of hybrids and EVs, but for the 2016 BMW 335i xDrive Gran Turismo, it’s a reasonable trade-off for its unique blend of sporty performance, spaciousness, and all-weather capability. This isn’t a car bought by hypermilers; it’s a car for those who appreciate a refined driving experience and need the practicality of a hatchback without succumbing to the blandness of a traditional SUV or wagon.

City and highway performance

The EPA estimates the 335i xDrive Gran Turismo at 20 MPG in the city and 30 MPG on the highway. The city figure reflects the realities of stop-and-go traffic where the 3.0L turbocharged inline-six engine’s responsiveness comes at the cost of fuel efficiency. However, the highway figure is more respectable, showcasing the engine’s ability to cruise efficiently at higher speeds. Considering the car’s curb weight and standard all-wheel drive system, achieving 30 MPG on the highway is BMW’s engineering, even if the number itself isn’t class-leading.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 BMW 335i xDrive Gran Turismo at exactly $2,500. This figure is based on driving 15,000 miles per year and using national average fuel prices. It provides a reasonable benchmark for potential owners to estimate their fuel expenses. However, actual fuel costs can vary depending on individual driving habits, local fuel prices, and the type of fuel used. The 335i expects premium fuel to deliver its maximum performance and efficiency, so budgeting for higher fuel costs is advisable.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy depends heavily on driving style and conditions. Drivers who frequently exploit the engine’s power will likely see numbers below the EPA estimates. Conversely, those who prioritize smooth acceleration, anticipate traffic, and maintain consistent highway speeds may achieve figures closer to, or even slightly above, the EPA ratings. The xDrive all-wheel-drive system also has a minor impact on fuel economy, as it adds weight and drivetrain losses compared to a rear-wheel-drive configuration.

How it compares

Compared to its rivals, the 2016 BMW 335i xDrive Gran Turismo’s fuel economy falls somewhere in the middle of the pack. For example, the Audi A5 Sportback, with its 2.0-liter turbocharged four-cylinder engine, manages around 24 MPG combined. The Porsche Macan, while offering similar performance thrills, typically delivers fuel economy closer to 20 MPG combined, especially in its more powerful configurations. The larger BMW 5 Series Gran Turismo, though conceptually similar, sacrifices fuel economy, offering around 21 MPG combined. The 335i GT is a niche vehicle, and its fuel economy reflects the compromise between performance, practicality, and efficiency that its target buyer is prepared to accept. For all BMW fuel economy data, this model’s efficiency is about average for its era.

Tips to maximize efficiency

Take advantage of the “Eco Pro” driving mode. This mode adjusts throttle response, transmission shift points, and climate control settings to prioritize fuel efficiency. Even if you normally prefer the sportier settings, engaging Eco Pro on long highway stretches can noticeably improve your MPG without sacrificing too much performance.

Avoid aggressive acceleration and hard braking. The 335i xDrive Gran Turismo’s turbocharged engine rewards smooth, gradual acceleration. Anticipate traffic flow and maintain a consistent speed whenever possible. Every time you floor the accelerator, you’re burning unnecessary fuel.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the driver’s side doorjamb. Even a slightly deflated tire can have a small but cumulative effect on your MPG.

Minimize unnecessary weight. The heavier your vehicle, the more fuel it consumes. Remove any unnecessary items from your trunk or cargo area that you don’t need on a regular basis. Every extra pound adds up, especially under acceleration.
