The 2021 BMW 330e xDrive achieves 25 MPG combined. This fuel economy won’t break any records, but it balances the BMW driving experience and all-weather security with the benefits of electrification. It’s a sport sedan that plugs in, not an efficiency-focused car like a Prius.

City and highway performance

The EPA estimates the 330e xDrive gets 22 MPG in the city and 30 MPG on the highway. These figures highlight the plug-in hybrid’s dual nature. In cities, drivers can use the electric motor for short trips, improving fuel economy or even driving without using any gas if their commute is within the car’s 20-mile electric range. The hybrid system smoothly blends electric and gasoline power, and the electric motor provides adequate acceleration. On the highway, the 30 MPG figure is respectable, showing the 2.0L 4-cylinder engine’s efficiency at consistent speeds. Expect lower fuel economy with aggressive acceleration and higher speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 BMW 330e xDrive at $2,300. This is based on 15,000 miles per year with combined city and highway driving, assuming average national fuel prices. Individual fuel costs will change based on driving, local fuel prices, and charging frequency. Drivers who primarily use the 330e xDrive for short commutes and regularly charge the battery can expect to spend less on gasoline and see better overall fuel economy.

Real-world expectations

The official MPG figures are a starting point, but real-world fuel economy depends on driving style and charging. Someone with short commutes who plugs in the car every night might average over 30 MPG. A driver with a longer commute who rarely charges could see figures closer to the EPA’s 25 MPG combined estimate, or lower. The 330e xDrive rewards active engagement with its hybrid system. The car’s computer is designed to maximize efficiency based on typical routes. Expect reduced fuel consumption from aggressive driving, frequent Sport mode use, and extended high-speed highway driving.

How it compares

The 2021 BMW 330e xDrive occupies a specific place in the luxury sedan market. The non-hybrid BMW 330i xDrive achieves around 28 MPG combined. The Lexus IS 350 AWD, a popular alternative, gets around 22 MPG combined, making the 330e more efficient. A purely electric vehicle like the Tesla Model 3 offers better efficiency (MPGe ratings over 130), but lacks the gasoline engine’s flexibility. The Acura TLX returns around 24 MPG combined with its SH-AWD system, similar to the 330e’s number. Ultimately, the 330e appeals to buyers wanting a balance of performance, efficiency, and all-wheel drive, and who will actively manage charging to benefit.

Tips to maximize efficiency

Prioritize electric-only mode for short trips to use less gas, taking advantage of the 330e xDrive’s electric range. Plug in the vehicle whenever possible at home, work, or public charging stations. Charging the car often is the best way to improve fuel economy.

Use the car’s navigation system. The 330e xDrive anticipates hills and traffic to manage power and regenerative braking. This can improve efficiency on longer trips by managing the battery’s charge.

Avoid hard acceleration and braking. Driving smoothly improves efficiency in any vehicle, especially a hybrid. Accelerate gently and anticipate traffic to minimize hard braking to help the battery recharge and reduce fuel use.

Check tire pressure regularly. Low tire pressure raises rolling resistance, reducing fuel economy. Check tire pressures monthly and inflate them to the recommended levels, found on a sticker inside the driver’s side door.
