2. How Fuel Tank Capacity Affects Your Driving Range
Your BMW M5’s fuel tank capacity is directly linked to its potential driving range – the distance you can travel on a single tank of gas. While the tank size is fixed at around 21.1 gallons for many models, the actual distance you cover will depend heavily on your driving habits and the specific M5 model’s fuel efficiency. For instance, a more aggressive driving style, characterized by rapid acceleration and high speeds, will consume fuel much faster, significantly reducing your range. Conversely, gentle, consistent driving, especially on highways, will maximize your miles per gallon (MPG) and extend your range. If you’re planning a long road trip, understanding both your M5’s fuel tank capacity and its typical MPG under your driving conditions will help you plot your refueling stops efficiently. A rough estimate for the M5’s highway range, given its typical MPG figures, can often exceed 300 miles on a full tank, but this is highly variable. For a more precise understanding, monitoring your car’s trip computer is invaluable.
3. BMW M5 Fuel Tank Capacity Benchmarks Across Generations
While the 21.1-gallon capacity is common for recent M5 models, it’s interesting to see how this has evolved over the M5’s storied history. While specific figures can vary, many earlier generations also featured substantial fuel tanks to support their grand touring capabilities. For example, the E60 M5 generation, known for its powerful V10 engine, also boasted a fuel tank capacity of around 16.6 gallons (approximately 63 liters), which was generous for its time. The E39 M5 generation typically had a capacity of about 18.0 gallons (around 68 liters). These figures highlight BMW’s consistent approach to equipping their M5 models with tanks that support their intended use as high-performance vehicles capable of long-distance travel. The increase in capacity in later models reflects both the increasing size of the vehicles and the engineering to accommodate larger fuel pumps and emissions control systems. Below is a comparison of approximate fuel tank capacities for select BMW M5 generations:
| BMW M5 Generation | Approximate Fuel Tank Capacity (U.S. Gallons) | Approximate Fuel Tank Capacity (Liters) |
|---|---|---|
| F90 (2018-Present) | 21.1 | 80 |
| F10/F11 (2011-2016) | 21.1 | 80 |
| E60/E61 (2005-2010) | 16.6 | 63 |
| E39 (1998-2003) | 18.0 | 68 |
| E34 (1988-1996) | 21.1 | 80 |
Note: These figures are approximate and may vary slightly based on specific model year and region. Always refer to your vehicle’s owner’s manual for exact specifications.
4. Factors Influencing Your M5’s Fuel Economy
While your BMW M5’s fuel tank capacity dictates how much fuel it can hold, its fuel economy determines how far that fuel will take you. Several factors significantly influence your M5’s MPG. Firstly, driving style is paramount. Aggressive acceleration, hard braking, and high speeds consume fuel rapidly. Smooth, consistent acceleration and anticipating traffic flow can dramatically improve efficiency. Secondly, vehicle maintenance plays a crucial role. Properly inflated tires reduce rolling resistance, and regular engine tune-ups, including clean air filters and spark plugs, ensure the engine runs optimally. The type of fuel used can also make a difference; using the manufacturer-recommended premium gasoline is essential for optimal performance and efficiency in a high-compression engine like the M5’s. Environmental factors also contribute: driving in stop-and-go city traffic is inherently less fuel-efficient than cruising on the open highway.

5. Tips for Maximizing Your BMW M5’s Fuel Efficiency
Maximizing your BMW M5’s fuel efficiency isn’t just about saving money; it’s about making the most of the incredible engineering under the hood. Here are some practical tips to help you achieve better MPG:
- Drive Smoothly: Avoid sudden acceleration and braking. Gently apply the accelerator and coast when possible.
- Maintain Optimal Tire Pressure: Underinflated tires increase rolling resistance, forcing your engine to work harder. Check your tire pressure regularly and keep it at the manufacturer’s recommended level.
- Reduce Weight: Remove any unnecessary heavy items from your trunk or cabin. Extra weight requires more fuel to move.
- Minimize Idling: If you’re going to be stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine.
- Use Eco Mode (If Available): Many modern BMWs, including the M5, feature different driving modes. “Eco Pro” or similar modes are designed to optimize fuel consumption.
- Plan Your Routes: Combine errands to avoid multiple cold starts and short trips, which are less fuel-efficient. Utilize navigation systems to find the most direct routes and avoid unnecessary mileage.
- Keep Up with Maintenance: Ensure your M5 receives regular oil changes, air filter replacements, and spark plug checks. A well-maintained engine runs more efficiently.
Pro Tip: Before embarking on a long road trip, ensure your tires are properly inflated and that you have a full tank of premium gasoline. This simple preparation can significantly improve your vehicle’s range and fuel efficiency.
6. Understanding the Fuel Reserve and Warning Light
Every car, including your BMW M5, has a fuel reserve – a small amount of fuel left in the tank after the low fuel warning light illuminates. This reserve is a safety feature to prevent the engine from stalling unexpectedly. For most vehicles, including the M5, this reserve is typically around 2-3 gallons. When your M5’s low fuel warning light comes on, you generally have enough fuel to travel an estimated 30-50 miles, depending on your driving conditions and real-time fuel consumption. However, it’s strongly advised not to rely on this reserve regularly. Running the fuel tank very low can potentially draw sediment from the bottom of the tank into the fuel system, which could lead to costly repairs. It can also cause the fuel pump to overheat as it relies on gasoline for cooling. Therefore, it’s best practice to refuel when the gauge reaches or slightly exceeds the quarter-tank mark, ensuring your M5’s fuel system remains in optimal condition.
