25 MPG combined is fine for the 2020 BMW 840i Coupe 3.0L 6-cyl. It’s a statement piece, a luxury coupe that’s stylish and performs well. Its drivers probably care more about enjoying the drive and getting attention than saving gas.

City and highway performance

The EPA estimates the 840i Coupe at 23 MPG in the city and 30 MPG on the highway. These numbers show the trade-offs between stopping and going in the city and cruising on the highway. The 23 MPG city rating is good for a car with this much power and weight. However, expect this number to drop if you’re often in traffic or accelerating quickly. The 30 MPG highway rating is achievable, especially on long trips where the 840i can stretch its legs and the engine runs efficiently. This is where the car excels, easily covering miles.

Annual Fuel Cost

The EPA estimates the annual fuel cost for the 2020 BMW 840i Coupe at $2,300. This is based on driving 15,000 miles a year, using average national premium gasoline prices. Your actual fuel costs can change depending on your driving and local fuel prices. Driving hard, taking short trips, and living where gas is expensive can increase your costs. Understanding how this is calculated helps 840i owners budget and reduce fuel use.

Real-World Expectations

The EPA provides a standard, but real-world fuel economy can be different. Drivers who enjoy the 840i’s engine and handling might see numbers closer to the low 20s in combined driving. However, drivers who mostly drive on the highway and drive efficiently could get over 30 MPG on the highway, perhaps even reaching the mid-30s. Your driving and how you use the car will determine your actual fuel economy.

How It Compares

The 840i is in a class where performance and luxury are more important than saving fuel. The Mercedes-Benz C300 Coupe gets about 28 MPG combined, but it gives up some of the 840i’s power. The Lexus RC 350 F Sport drives like the BMW, but it gets about 23 MPG combined, lower than the 840i. Even the Porsche 911 Carrera, a sports car, gets around 21 MPG in the city and 28 MPG on the highway. Buyers of the 840i are okay with certain fuel consumption for its unique blend of performance, luxury, and exclusivity. You can also review 840I MPG across all years to see if a different model year suits your needs.

Tips to Maximize Efficiency

Driving smoothly is important. Avoid accelerating and braking hard, predict traffic, and keep a steady speed when you can. The 840i’s automatic transmission is designed for efficiency; let it shift smoothly and don’t change gears manually unless you have to.

Correct tire inflation is critical for fuel economy. Check your tire pressure often and make sure it meets the specifications on the driver’s side door. Underinflated tires increase resistance, making the engine work harder and burning more fuel.

Remove extra weight from the car. Take out anything from the trunk or cabin that you don’t need, because extra weight increases fuel use. Every pound increases fuel consumption, especially when accelerating.

Try using the 840i’s driving modes. Selecting “Eco Pro” mode optimizes the car’s settings for the best fuel efficiency. This mode adjusts the throttle, shift points, and climate control to save fuel, but it can reduce the car’s responsiveness.
