23 MPG combined. That’s not going to win any hypermiling competitions. But for the buyer who chooses the 2015 BMW 335i xDrive Gran Turismo, fuel economy is often a secondary consideration. This isn’t about squeezing every last mile from a gallon; it’s about getting a practical wagon-esque experience, a potent turbocharged six-cylinder engine, and all-wheel-drive confidence in a package that, while polarizing in its looks, provides a uniquely versatile driving experience. These buyers prioritize space and performance, and they’re willing to accept a fuel bill that reflects those choices.

City and highway performance

The EPA estimates offer a breakdown of the 335i xDrive Gran Turismo’s fuel consumption. In city driving, expect around 20 MPG. Stop-and-go traffic and the engine’s eagerness to rev will decrease gas mileage. On the open road, that figure climbs to a more respectable 30 MPG. This disparity highlights the engine’s efficiency at cruising speeds, aided by the smooth-shifting eight-speed automatic transmission. The xDrive all-wheel-drive system also contributes, adding a degree of mechanical drag compared to a rear-wheel-drive model but providing improved traction in all conditions.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2015 BMW 335i xDrive Gran Turismo 3.0L 6-cyl at precisely $2,500. This figure is based on driving 15,000 miles per year and using the national average fuel price for premium gasoline, which this engine requires. Your actual fuel costs will vary depending on your driving habits, the type of driving you do, and the price of gasoline in your area. Aggressive driving or consistent short trips will inflate this number, while more highway-heavy commutes could lower it.

Real-world expectations

While the EPA figures provide a benchmark, real-world MPG often deviates. Owners of the 335i xDrive Gran Turismo frequently report figures mirroring the EPA’s estimates, though some experience lower numbers, particularly in urban environments. You can expect the best economy on longer highway trips at a steady pace. Short trips around town will yield much lower numbers. The key is adapting your driving style to maximize efficiency. Something easily forgotten with that tempting turbocharger. Regular maintenance, including properly inflated tires, is also key to getting the best fuel economy. For a broader view, reviewing 335I MPG across all years can provide additional insights.

How it compares

Compared to its direct competitors, the 2015 BMW 335i xDrive Gran Turismo’s fuel economy is reasonably competitive. For instance, a comparable Audi A4 allroad from the same year, also featuring a turbocharged 2.0L four-cylinder and all-wheel drive, typically delivers around 24 MPG combined. The Volvo V60 Cross Country, known for its wagon practicality, achieves similar numbers in real-world driving to the A4 allroad. The BMW’s advantage is its more powerful engine, justifying the slight dip in fuel efficiency. This buyer isn’t cross-shopping with Prius owners. They’re comparing performance-oriented vehicles and understanding the trade-offs. Checking all Bmw fuel economy data can put this model in perspective.

Tips to maximize efficiency

Take advantage of the Eco Pro driving mode. This setting re-maps the throttle response and shift points, encouraging a more relaxed and efficient driving style. It might not be the most exhilarating way to experience the 335i’s power, but it can improve fuel economy, especially on longer journeys.

Minimize idling. An engine burns fuel while stationary. On cold days, modern engines warm up quickly while driving, making extended idling periods obsolete. Shutting off the engine during prolonged stops can save fuel.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels, typically found on a sticker inside the driver’s side doorjamb. A simple check with your tire gauge can make a big difference.

Anticipate traffic flow. Smooth acceleration and braking are key to maximizing fuel efficiency. By anticipating traffic changes and avoiding sudden stops, you can minimize wasted energy. A more even driving style helps the engine operate more efficiently.
