How to manage your fuel in ACC

Learn how to manage your fuel in ACC endurance events. Never miss a pitstop or run out of fuel again.

In Assetto Corsa Competizione there are a number of details that each driver must get right to give yourself the best opportunity to achieve the best result possible. 

One of the most vital details in any race is the amount of fuel used for a race. This is firstly to make sure the race can be completed, but there are a number of other reasons too. Another key feature of any race car is the engine maps, these will affect power, fuel consumption and throttle maps.

Understanding how both of these factors work can be key to extracting the most out of every race. In this piece, both will be covered giving you an insight into what to do, how to do it, and what advantages you could gain.

How do we calculate fuel? 

This task can sometimes be a bit confusing and difficult to interpret as there are a number of different metrics you can follow. First, we will cover where to find the relevant information to calculate the fuel load needed. 

The first place to look for an idea of your fuel consumption is the setup screen where an average fuel consumption figure will be displayed. The figure displayed will alter as more laps are completed and should be treated as a rough estimate. The second place, arguably more accurate, will be next to the tyre graphic while on track. The graphic will be updated in real-time so will show a better indication lap to lap on what is consuming more fuel and how as you push the car the consumption will change.

Now we have an understanding of where to find the fuel estimation the fuel loads can be calculated using already available information within the game. The simplest way to calculate your fuel is to use The Sim Grid Fuel Estimator.

You will need the following information to get the most accurate result:

  • Total race time 
  • Average lap time
  • Total laps 
  • Fuel per lap 
  • Fuel tank capacity

Once this information has been input you will receive an estimation of the fuel level needed and the number of stops required to complete the race. However, it must be noted these are estimations and it is always best to give yourself at least one lap of extra fuel to ensure you complete the race. 

If you’re short on time and need to calculate the fuel levels just before a race there is a simple equation that can be used 

FR = ((TR x 60) / TL ) x FL + (2 x FL)
  • FR – Fuel for race 
  • TR – Race duration in minutes
  • FL – Fuel per lap
  • TL – Average Lap Time 

This equation will output a similar result to the calculator so keep in mind these are estimations. 

What does fuel load affect?

As it has been covered, fuel load is an important factor in simply finishing the race but also affects on the car dynamics and tyre wear. 

In simple terms, less fuel in the car means there is less weight on board and with less weight, the car becomes more direct, faster over a stint and tyres wear out less. However, running less fuel than needed will require fuel saving to be done throughout the driving stint. If you must fuel save this means you will begin to lose lap time through techniques such as lifting and coasting or short-shifting. 

It will be a fine balancing act to be able to understand how much time will be lost or gained through a lighter car and less tyre wear, as a rule of thumb this is not recommended to amateurs as driving to your maximum pace will ultimately be faster. 

Although it may seem counterintuitive running a slightly heavier car – using more fuel can provide some benefits to yourself as a driver. One reason is that the more fuel you carry the more you can push the car, use all the revs and be confident you will complete the race.

Another benefit can be a more stable car as the weight will keep the car more planted through the corners. However, it should be noted a heavier car will reduce average lap time and potentially add an increase to tyre wear over a full stint.

The best way to approach the level of fuel that is best for a race is to run multiple stint simulations yourself in a practice session. Running these sessions will allow you to see how the fuel is consumed and get a feeling for how running different levels will change the car’s characteristics. Most importantly practice will give you confidence that you have made the right choices and can focus solely on the driving 

What are Engine Maps?

In simple terms, engine maps are settings for the car that will adjust factors such as; fuel consumption, throttle maps and power output. Getting these settings correct in each situation is key to getting the most out of your car not only with fuel, but also to maximise the life of the tyre. In this guide, we shall explain the engine maps settings in ACC.

Dry Condition Map

  • Full power with highest fuel consumption and most aggressive throttle map.
  • Full power with lower fuel consumption and more gradual throttle map.
  • Lower power with lowest fuel consumption and a progressive throttle map. 

Wet Condition Map 

  • Full power with high fuel consumption and a much more gradual throttle map. 
  • Full power with lower fuel consumption and a much more gradual throttle map. 
  • Lower power with lowest fuel consumption and a much more gradual throttle map. 

Pace Car Map 

  • Lowest power with lowest fuel consumption, only to be used behind a pace car.

As you can see there a number of different settings covering a range of different needs and situations.

Looking first in detail at the dry engine maps, these are the most commonly used settings to provide the best power and throttle response and therefore allow you to extract the most pace from the car. In almost every dry condition race you will want to use the most powerful engine map other than for personal preference, where you want to change the throttle map to be more progressive or gradual.

The adjustments in fuel settings are often negligible and there are much more effective methods in adapting your driving style that can save on fuel, such as lifting and coasting or short shifting to name a few.

Looking at wet condition maps, these are used when the track becomes damp or wet during quali or race conditions. What these maps will often do is reduce the aggressiveness of the power output by making the throttle more gradual rather than linear and reducing overall power output. These maps can be useful to most drivers as it allows you to be more consistent in wet conditions without making mistakes or spinning up the tyres and causing overheating.

Although it must be said some drivers are known to adapt their driving and continue using the dry map settings to give the most power potential, but be careful this can end in an easy mistake and is only recommended for the most experienced drivers.

The final setting is often a pace car setting, this is mainly there to mimic the similarities to the real life cars. What a pace car setting does is limit both the power of the engine and the reduce the fuel consumption to the absolute minimum. This will cause the car to be much slower and should not be used in a race situation.ACC does not currently support the use of pace cars so this setting is not to be used as is to limit fuel consumption to an extreme degree.

Now that you have a general understanding of what engine maps are and when and why to use them it is important you understand what each of these settings does in your chosen car. The reason for this is that not all of the cars use the exact same settings, some have up to 12 such as the Mclaren 720s and some only have 3 such as the Mercedes AMG. Here is the full list of all the engine maps created by ACC themselves for you to study for each and every car.
