The 2018 BMW 330i xDrive Gran Turismo, with its 27 MPG combined rating, suits drivers who value space and all-weather capability more than ultimate fuel efficiency. This liftback sedan combines versatility and driving pleasure, appealing to a particular driver who’s okay with a few less MPG in exchange for the added utility and unique styling of the GT body style.

City and highway performance

EPA estimates put the 2018 BMW 330i xDrive Gran Turismo at 23 MPG in the city and 33 MPG on the highway. These figures come from its 2.0L turbocharged 4-cylinder engine working with an 8-speed automatic transmission and BMW’s xDrive all-wheel-drive system. The city MPG shows the engine’s efficiency when not constantly cruising at high speed, and the highway MPG shows how the 8-speed transmission optimizes engine RPM at higher speeds. These numbers will vary based on driving style and traffic, like any vehicle.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2018 BMW 330i xDrive Gran Turismo to be $2,150. This number uses the EPA’s combined MPG rating, an estimated 15,000 miles driven per year, and the national average fuel price at the time of calculation. Remember that this is an estimate, and your actual costs can change based on your driving, the fuel you use, and fuel price changes. Drivers covering significantly more or less than 15,000 miles a year will see a direct effect on their yearly fuel spending.

Real-world expectations

While the EPA provides a standard estimate, real-world fuel economy often changes based on driving and conditions. Drivers who often drive fast or encounter stop-and-go traffic might see fuel economy closer to the 23 MPG MPG city figure. On the other hand, those who mainly drive on highways with little traffic could see numbers close to or even better than the 33 MPG highway rating.

Factors like tire pressure, car maintenance, and outside temperature can also change fuel consumption. The 330i GT rewards smooth, careful driving with better MPG, but its weight and all-wheel-drive system mean a higher baseline fuel use than a lighter, front-wheel-drive sedan.

How it compares

The 2018 BMW 330i xDrive Gran Turismo’s fuel economy is generally competitive compared to other vehicles in its class and price range. A similarly equipped Audi A4 allroad, for example, gets around 25 MPG combined. The Mercedes-Benz C300 4Matic sedan, another competitor, is similar. More fuel-efficient options exist within BMW itself. The standard 330I MPG across all years in rear-wheel-drive typically rates slightly higher.

Buyers of the Gran Turismo often value its unique style and cargo space, accepting a slight MPG trade-off for these advantages. For those considering other BMW models, all Bmw fuel economy data is easily accessible.

Tips to Maximize Efficiency

Drive smoothly and evenly. Avoid fast acceleration and braking, as these burn more fuel. Predict traffic and keep a consistent speed when possible. The 330i GT’s turbocharged engine provides enough torque for relaxed driving even at low RPMs.

Make sure your tires are inflated correctly. Underinflated tires increase rolling resistance, which lowers fuel economy. Check your tire pressure often and inflate them to the specifications listed on the driver’s side doorjamb.

Reduce aerodynamic drag. Remove unnecessary items from the roof rack or cargo carrier, as these can increase wind resistance and hurt fuel efficiency. Even leaving windows open at higher speeds can reduce your MPG.

Use the BMW’s driving modes. Select “Eco Pro” mode when trying to save fuel, as this mode optimizes engine and transmission settings for efficiency. Use “Comfort” or “Sport” modes when performance matters more.

Regular maintenance is important for fuel economy. Make sure your engine is tuned correctly and all fluids are at the correct levels. Addressing mechanical issues quickly can prevent them from hurting your fuel efficiency.
