The 730 has two powertrain versions. The official fuel consumption for the 3.0L automatic version is 9.9L/100km, with an actual fuel consumption of 12.6L/100km. The official fuel consumption for the 3.0T automatic version is 8.9L/100km, with an actual fuel consumption of 12.2L/100km. Below is a related introduction about fuel consumption: Fuel consumption per 100 kilometers: This refers to the fuel consumption of a vehicle traveling a certain speed on the road for 100 kilometers. It is a theoretical indicator of the vehicle. The fuel consumption per 100 kilometers is a value measured by the manufacturer in an objective environment using a dynamometer installed on the vehicle's chassis, converted into speed parameters, and then calculated under specified speeds to determine the theoretical experimental fuel consumption data per 100 kilometers for the model. Road condition fuel consumption: Road condition fuel consumption is a fuel indicator calculated by repeatedly testing the values measured when a vehicle travels on specified roads at specified speeds and times, also known as multi-condition road cycle fuel consumption. In the specification, each cycle includes various driving conditions, and records driving conditions according to specified shift times, parking times, driving speeds, acceleration, braking, and deceleration indicators in each cycle. The measured values using this method are closer to actual values.

I've driven a 730, with fuel consumption around 11 to 13 liters per 100 km in the city, and it can drop to about 7 liters on the highway. On average, 10 liters is the norm. As a daily commuter, I think the 'gas guzzler' reputation is well-deserved, especially in heavy city traffic when I press the accelerator a bit harder, and the fuel consumption spikes. I usually drive in eco mode, avoiding sudden braking and hard acceleration, which helps save some money. When fuel prices are high, every liter counts. I recommend regularly checking tire pressure and air filters—these small actions can improve fuel efficiency and save a significant amount over a year.

As an experienced driver, the fuel consumption of my 730 affects me significantly. Driving in the city for daily commutes, the average fuel consumption is slightly over 10 liters, which is a bit higher than expected. I've compared it with similar models like the Audi A8 or Mercedes-Benz S-Class, and they're roughly at the same level. The secret to saving fuel is planning routes in advance to avoid peak hours and using cruise control more often on highways. As the car ages, fuel consumption might increase slightly, so I perform maintenance every six months, cleaning engine carbon deposits to ensure smooth fuel flow. I always refuel with high-quality gasoline when the fuel gauge light comes on, never waiting until the tank is empty.

I'm a long-distance driving enthusiast and find the fuel efficiency of my 730 on highways quite impressive, typically maintaining around 7 liters per 100 kilometers. On a full tank, it can cover over 600 kilometers on a long trip, which is quite reliable. In mountainous or hilly areas, the fuel consumption slightly increases to 8 liters, but it doesn't affect the overall performance. Pay attention to the lightweight body design and low drag coefficient—BMW has done a great job with these details. Before a long trip, it's advisable to check the vehicle's condition, maintain a steady speed, and avoid excessive use of air conditioning or sudden temperature adjustments. These small habits can help extend your journey.

As a new 730 owner, I initially thought luxury cars would have low fuel consumption, but was surprised to find it actually exceeded 12 liters. It's particularly challenging to save fuel in city traffic with frequent traffic lights. I've started adjusting my driving habits, such as gradual acceleration from stops and reducing sharp turns. Fellow car enthusiasts mentioned that cold starts and seasonal changes also affect fuel efficiency, with higher consumption during winter when using the heater more frequently. Regular maintenance is crucial—I check the spark plugs and fuel lines every three months to prevent clogs. After learning some fuel-saving techniques, I've managed to reduce consumption to around 9 liters, which feels worthwhile.

As an environmentally conscious individual, I find the 730's average fuel consumption of around 10 liters acceptable though not perfect, with room for improvement. The engine performs relatively efficiently during highway driving, resulting in decent carbon emissions, but pollution increases significantly in congested urban traffic. I've started adopting hybrid driving techniques, such as turning off the engine when parked and minimizing coasting in neutral. Future models with electric versions would be preferable for fuel savings and environmental protection. I recommend choosing low-resistance tires and maintaining a clean vehicle body – these small actions collectively contribute significantly to fuel efficiency, allowing everyone to practice green living.
