16 MPG combined is not going to win the 2019 Mercedes-Benz Maybach S650 any honors for lower fuel costs. But frankly, lower fuel costs are not on the minds of those who purchase this rolling palace. This is a vehicle for those who prioritize supreme luxury, effortless power, and undeniable presence above all else. Fuel economy is a distant consideration, a mere line item in the cost of owning one of the most exclusive automobiles on the road.

City and highway performance

The EPA estimates for the Maybach S650 break down to 13 MPG in the city and 21 MPG on the highway. The city figure, unsurprisingly, suffers most from the stop-and-go nature of urban driving, a situation where the 6.0L V12’s prodigious power is largely untapped. The highway number, while still low relative to more mainstream vehicles, reflects the engine’s ability to cruise effortlessly at high speeds. The seven-speed automatic transmission is geared for relaxed progress, and the abundance of torque means downshifts are rarely necessary, contributing to a more efficient (relatively speaking) highway experience.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2019 Mercedes-Benz Maybach S650 at $3,600. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, at the national average fuel price. While this is a significant sum compared to more fuel-efficient vehicles, potential Maybach owners are unlikely to be deterred. The cost of fuel is a small fraction of the overall expense associated with owning and maintaining a vehicle of this caliber.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy can vary significantly depending on driving habits and conditions. Aggressive acceleration, frequent hard stops, and extended idling will all negatively impact fuel consumption. Similarly, driving primarily in congested urban areas is likely to result in fuel economy below the EPA’s city estimate. Conversely, consistent highway cruising at moderate speeds could potentially yield slightly better results than the EPA’s highway figure. However, it’s safe to assume that most Maybach S650 owners are less concerned with squeezing every last mile out of each gallon and more focused on the comfort and convenience of their journey. They may be interested in all Mercedes Benz fuel economy data but are unlikely to drastically alter their driving style to improve their MPG.

How it compares

Compared to other ultra-luxury sedans, the Maybach S650’s fuel economy is predictably at the lower end of the spectrum. For instance, the Rolls-Royce Phantom, with its larger 6.75L V12, achieves an EPA-estimated 12 MPG combined. The Bentley Flying Spur, equipped with a W12 engine, manages around 15 MPG combined. Even the more technologically advanced plug-in hybrid versions of the Porsche Panamera, while offering significantly better fuel economy in hybrid mode, can’t match the effortless character of the Maybach’s V12 when relying solely on gasoline power. Other S-Class models can achieve higher MPGs, and more data is available on MAYBACH MPG across all years. However, for the very specific buyer seeking the ultimate in handcrafted luxury and a twelve-cylinder engine, the competition simply isn’t relevant. They are buying an experience, not merely transportation.

Tips to maximize efficiency

While outright fuel efficiency might not be a primary concern, a few simple adjustments can help minimize fuel consumption without compromising the Maybach S650’s driving experience.

Gentle acceleration and smooth braking are key. The V12 engine delivers prodigious torque at low RPMs, so there’s no need to aggressively push the accelerator pedal. Anticipating traffic flow and avoiding sudden stops will also conserve fuel.

Ensure proper tire inflation. Correctly inflated tires reduce rolling resistance, which can improve fuel economy. Consult the vehicle’s owner’s manual or the sticker on the driver’s side door jamb for the recommended tire pressure.

Minimize idling. Modern engines consume fuel even when idling, so avoid prolonged periods of idling, especially in traffic. Turn off the engine if you anticipate being stopped for more than a minute.

Use cruise control on the highway. Cruise control maintains a consistent speed, which can help optimize fuel economy during long highway drives. However, avoid using cruise control in hilly terrain, as the system may downshift frequently, negating any potential fuel savings.
