Many 2019 BMW 640i xDrive Gran Turismo owners accept 23 MPG combined as part of the ownership experience. This isn’t a fuel-sipping hybrid; it’s a spacious, luxurious hatchback designed for covering vast distances in comfort and style. Its buyers prioritize a smooth, powerful engine, all-wheel drive confidence, and a uniquely versatile cargo area over outright fuel efficiency. They understand the tradeoff involved in owning a vehicle that’s as much a high-speed cruiser as it is a practical family hauler.

City and highway performance

The EPA estimates the 2019 640i xDrive Gran Turismo at 20 MPG in the city and 28 MPG on the highway. The city rating reflects the demands of stop-and-go traffic on the 3.0L turbocharged inline-six engine, where frequent acceleration and idling take their toll.

The highway figure demonstrates the engine’s ability to cruise efficiently at higher speeds, aided by the smooth-shifting eight-speed automatic transmission (S8). Consider the highway MPG a more realistic projection for long road trips; this vehicle is designed to tackle those trips with ease.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 BMW 640i xDrive Gran Turismo at $2,500. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel cost will vary depending on your driving habits, the type of fuel you use (premium is recommended), and local fuel prices.

If your driving is mostly city-based or you have a heavy foot, expect to exceed this estimate. Drivers who predominantly log highway miles might land below the $2,500 mark. It’s one thing to review all all Bmw fuel economy data and find the right car, it’s another to adjust your habits to reach that MPG.

Real-world expectations

While the EPA provides a standardized benchmark, real-world MPG often differs. Owners of the 640i xDrive Gran Turismo frequently report numbers close to the EPA estimates, but achieving the 28 MPG highway figure requires diligent driving habits and minimizing aggressive acceleration. Factors such as weather, tire pressure, and cargo weight can also influence fuel consumption. Some drivers report slightly lower MPG if they’re consistently using the xDrive all-wheel-drive system in demanding conditions, versus dry pavement cruising.

How it compares

In the realm of large luxury hatchbacks and wagons, the 2019 640i xDrive Gran Turismo’s fuel economy positions it competitively. Other vehicles in this segment, such as the Audi A7, offer similar blends of luxury and practicality. For example, a 2019 Audi A7 with its 3.0L turbocharged V6 achieves an EPA-estimated 22 MPG combined, making it a close competitor. The Mercedes-Benz CLS-Class, while more stylish, often sacrifices some MPG for its sleek design. A 2019 CLS 450 delivers around 24 MPG combined. Buyers considering the 640I MPG across all years generally prioritize space and comfort; if efficiency is important, some may consider a smaller or hybrid luxury vehicle, but then give up the unique blend of space and cruising ability that defines the Gran Turismo.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the 640i xDrive Gran Turismo. The turbocharged engine delivers ample power, but resist the urge to constantly exploit it. Smooth, deliberate acceleration will significantly improve your MPG, especially in urban environments.

Maintain optimal tire pressure. Check your tire pressure regularly and inflate your tires to the recommended PSI, which is usually found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, which decreases fuel efficiency.

Minimize idling. Modern engines are designed to be efficient even when starting, so avoid letting the engine idle for extended periods. If you’re waiting for more than a minute, it’s generally more fuel-efficient to turn the engine off completely.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which reduces unnecessary acceleration and braking. This can improve fuel economy, especially on long highway drives, and using cruise control reduces driver fatigue, making those long trips more pleasant.

Remove unnecessary weight. Carrying extra weight in your vehicle reduces fuel economy. Clean out any unnecessary items from the trunk and passenger compartment to lighten the load. Every little bit helps, especially in stop-and-go traffic.
