What You'll Learn

The McLaren MP4-12C has a 16-gallon fuel tank
The McLaren MP4-12C is a high-performance car with a 16-gallon fuel tank. This car is an engineering marvel, boasting a small-ish 3.8-liter engine that, with the help of two turbines, can output 592 horsepower. Tuners can modify the car to increase horsepower even further, with some reporting figures of over 800 horsepower.
The MP4-12C's fuel system is designed to provide the engine with the fuel it needs to generate impressive power. The car's fuel tank capacity is 16 gallons, as mentioned, and it utilizes a Sequential MPI fuel system. While I couldn't find explicit confirmation, it is likely that the 16-gallon figure refers to the US gallon, which is approximately 3.79 liters. This would mean the fuel tank can hold roughly 60.64 liters.
The McLaren MP4-12C's fuel tank size and fuel system contribute to its overall performance. The car's fuel system is designed to provide the necessary fuel flow to the engine, ensuring it can produce the desired horsepower and torque figures. The fuel tank capacity provides a good balance between weight and range, as a larger fuel tank would add more weight, affecting the car's performance and handling.
Additionally, the MP4-12C has become known for its distinctive "flames" shooting out from the exhaust. This phenomenon is caused by unburnt fuel detonating in the exhaust when the throttle body is closed, creating a rich condition. The amount of fuel used for these flames is minuscule compared to the total fuel tank capacity.
The McLaren MP4-12C's 16-gallon fuel tank is an essential component of this high-performance vehicle, providing the necessary fuel for its powerful engine while maintaining the car's overall balance and handling characteristics.

The handbook states the tank capacity is 60 litres
The handbook states the tank capacity of the McLaren MP4-12C is 60 litres. This is further supported by a McLaren driver who measured that their car only used 11 gallons of fuel when they filled up their tank with 40 miles of range left.
However, there is some discrepancy in the literature. The McLaren Automotive website and a dealer's options document both state that the fuel tank capacity is 72 litres. This confusion may have arisen from the handbook author using Imperial gallons, which equate to 72 litres, but treating them as US gallons, which equate to 60 litres.
The difference between these two figures is significant, especially when considering the range of the vehicle. If the tank is 60 litres, then when the gauge hits empty, there are approximately 8 litres left in the tank and an "emergency range" of 30 miles. If the tank is 72 litres, then there are 20 litres left when the gauge hits empty, with an increased range of 75 miles.
The McLaren MP4-12C is a high-performance vehicle, and its fuel tank capacity is an important consideration for owners. While the handbook states a capacity of 60 litres, other sources suggest a higher capacity of 72 litres. This discrepancy may be due to a unit conversion error in the handbook.

McLaren Automotive website lists capacity at 72 litres
The McLaren MP4-12C is a high-performance car manufactured by McLaren Automotive, a company known for producing technologically advanced racing cars. While the exact fuel tank capacity of the McLaren MP4-12C is not explicitly stated, there is information available on the McLaren Automotive website that provides insight into this matter.
According to the McLaren Automotive website, the fuel tank capacity of the McLaren 750 Spider is specified as 72 litres. This information is confirmed by a dealer who provided documentation indicating that the fuel tank capacity of the McLaren 750 Spider is indeed 72 litres. This clarification addresses a discrepancy where the handbook for the 750 Spider stated the fuel tank capacity as 60 litres, which would be accurate if calculated based on imperial gallons, but not US gallons.
The relevance of this information to the McLaren MP4-12C lies in the fact that both vehicles are part of McLaren's supercar model lineup, which includes the 12C and the 720S. While the fuel tank capacity of the MP4-12C may not be identical to that of the 750 Spider, the consistency in fuel tank capacity within McLaren's supercar models suggests that the MP4-12C may also have a similar capacity.
Furthermore, a discussion on McLaren Life, a forum dedicated to McLaren vehicles, provides additional insights. In this discussion, a user raises the question of determining the accurate fuel tank capacity of their McLaren 750 Spider. They note that the printed and PDF versions of the handbook state a capacity of 60 litres, while the McLaren Automotive website specifies 72 litres. This discrepancy prompts the user to investigate further, leading to their dealer confirming the capacity as 72 litres.
While the focus of this discussion is on the McLaren 750 Spider, the fact that it shares a platform and powertrain with the MP4-12C suggests that the fuel tank capacities of the two vehicles could be similar. It is important to note that the fuel tank capacity of a vehicle can vary depending on various factors, including the model year, trim level, and any modifications made. Therefore, while the McLaren Automotive website lists a capacity of 72 litres for the 750 Spider, the actual fuel tank capacity of the McLaren MP4-12C may differ.

The car can go 75 miles when the gauge shows empty
The McLaren MP4-12C is a high-performance vehicle with a 16-gallon fuel tank capacity. While there is no standard number of miles a car can go when the gauge shows empty, it is generally unsafe to push your vehicle to its limits. Most vehicles have a buffer of two to four gallons left in the tank after hitting "E", and the number of miles you can drive depends on factors such as the type of car, driving conditions, and fuel efficiency.
Smaller vehicles with smaller fuel tanks, like compact cars, may not go as far on empty as larger vehicles with bigger fuel tanks, such as SUVs. On average, smaller cars can travel about 40-50 miles on empty, while larger vehicles can go as far as 75 to 100 miles.
If your car has good fuel efficiency, it will be able to go further on an empty tank than a car with poor fuel efficiency. For example, a hybrid car can go much further on a gallon of gas than a pickup truck. Additionally, a well-maintained car is more fuel-efficient than one that is poorly maintained, so the age of your vehicle may not impact its fuel economy as much as its maintenance history.
It is important to note that driving your car on low fuel can cause several issues, including fuel pump damage, sediment in the fuel tank, and reduced performance. The fuel pump relies on gasoline to stay cool and lubricated, and running on low fuel can cause the pump to overheat and fail prematurely. Therefore, it is recommended to refuel at around a 1/4 tank and not wait until the light comes on.
