What You'll Learn
GT3 car fuel consumption and performance
GT3 cars are grand tourer racing cars designed for use in various auto racing series worldwide. The GT3 category was initially created in 2005 as a third rung in the ladder of grand touring motorsport, below the Group GT1 and Group GT2 categories. The concept behind GT3 was to simplify the process of racing by combining several existing cars from one-make series, such as the Porsche Supercup or Ferrari Challenge, and allowing them to compete on a level playing field through strict control of their performance by the FIA.
GT3 cars are based on mass-production road car models that are being built and sold at the time of homologation. While the base car must be a road car, the engine does not have to be, for example, the BMW Z4 GT3 used a 4.0 V8, while the Mercedes-AMG GT3 used a 6.2 V8. There are almost no limits on engine sizes, configurations, chassis construction, or layout. The performance of all GT3 cars is regulated by the FIA through the balance of performance formulae, which adjusts limits on horsepower, weight, engine management, and aerodynamics to prevent a single manufacturer from dominating the class. The cars in GT3 are designed to have a weight between 1200 kg and 1300 kg, with horsepower between 500 hp and 600 hp.
GT3 cars can be used in sprint or endurance races, with manufacturers offering upgrade kits to enable their use in endurance races. The fuel consumption of a GT3 car will depend on various factors, including the race's fuel consumption rate, pit stop speed, and tire degradation. Engine mapping can also significantly impact fuel consumption, with different mappings resulting in reduced fuel consumption. For example, using mapping 6 can result in a 30%-38% reduction in fuel consumption, saving 1.3 liters per lap or 13 liters over 10 laps.
The fuel economy of a GT3 car will also depend on driving style, with different throttle inputs resulting in different consumption rates. Additionally, the type of transmission can impact fuel economy, with automatic transmissions offering better city fuel economy, while manual transmissions provide better highway fuel economy. For example, the 2025 Porsche 911 GT3 and GT3 RS are rated for 14 mpg city and 18 mpg highway with the automatic transmission, while the manual transmission drops the city figure to 13 mpg but increases the highway figure to 19 mpg.

GT3 car weight and horsepower
GT3, or Group GT3, is a set of regulations maintained by the Fédération Internationale de l'Automobile (FIA) for grand tourer racing cars. The category was conceived to use sprint formats for races, but manufacturers can develop and sell an upgrade kit to allow GT3 cars to be used in endurance races. GT3 cars are based on mass-production road car models that are being built and sold at the time of homologation. However, this does not necessarily include the engine. For example, the BMW Z4 GT3 used a 4.0 V8, while the Mercedes-AMG GT3 used a 6.2 V8 from the Mercedes SLS AMG GT3.
The performance of all Group GT3 cars is regulated, either by the GT Bureau of the FIA or by a series-specific ruling body, through the balance of performance formulae. This formula adjusts limits on horsepower, weight, engine management, and aerodynamics to prevent a single manufacturer from dominating the class. The cars in GT3 are designed to have a weight between 1200 kg and 1300 kg (2645 lbs and 2866 lbs) with horsepower between 500 hp and 600 hp. This results in all cars having a very similar power-to-weight ratio, achieved either by high power and high weight (e.g. the Mercedes-Benz SLS AMG) or low power and low weight (e.g. the Porsche 911 GT3).
The Porsche 911 GT3 and its variants, the GT3 RS and GT3 Touring, are examples of cars that fall under the GT3 category. The 4.0-liter engine in the GT3 produces 502 horsepower, while the same engine in the GT3 RS is tuned to generate 518 horsepower. The GT3 RS is considered the closest thing yet to a 911 race car for the street, with its outrageous rear wing and drag-reduction system similar to those on Formula 1 race cars. The GT3 and GT3 RS both feature a chassis derived from Porsche's 911 RSR and 911 GT3 Cup race cars, with a control-arm front suspension design and standard adaptive dampers for tremendous cornering grip and feedback.

GT3 car fuel capacity
The fuel capacity of GT3 cars varies depending on the make and model of the car, as well as the specific racing series and regulations. GT3, or Group GT3, is a set of regulations maintained by the Fédération Internationale de l'Automobile (FIA) for grand tourer racing cars. These regulations were first introduced in 2005 and have since expanded to become the standard for many national and international racing series.
GT3 cars are based on mass-production road car models, with a wide variety of car types homologated, including models from Porsche, Ferrari, Aston Martin, Dodge, and Nissan. While there is almost no limit on engine sizes and configurations, the performance of GT3 cars is strictly controlled by the FIA to ensure a level playing field for all competitors. This includes adjustments to limits on horsepower, weight, engine management, and aerodynamics.
The fuel capacity of GT3 cars can range from around 100 to 110 litres, as mentioned in a discussion about the Assetto Corsa Competizione videogame, which simulates the GT3 championship. However, it's important to note that the actual fuel consumption and range of these cars can vary depending on various factors such as racing conditions, pit stop strategies, and tire degradation.
In terms of fuel consumption, GT3 cars prioritize cooling, fuel efficiency, and reliability over outright power. This is due to the nature of endurance racing, where these cars may be competing in 24-hour races. GT3 engines are also detuned to reduce servicing costs, and their smaller engines and fuel tanks contribute to faster lap times compared to larger, more powerful cars.

GT3 car fuel capacity in racing
GT3 cars are grand tourer racing cars designed for use in various auto racing series worldwide. The concept behind Group GT3 was introduced by Stéphane Ratel, head of the SRO Group and promoter of the FIA GT Championship in 2005. GT3 cars are based on mass-production road car models that are being sold at the time of homologation. This does not necessarily include the engine, for example, the BMW Z4 GT3 used a 4.0L V8 while the Mercedes-AMG GT3 used a 6.2L V8. The performance of all GT3 cars is regulated by the FIA to prevent a single manufacturer from dominating the class.
GT3 cars are designed to have a weight between 1200 kg and 1300 kg, with horsepower between 500 hp and 600 hp. The fuel capacity of GT3 cars varies depending on the specific car and the race. For example, the Ferrari GT3 car has a maximum fuel capacity of 110 litres, while the Porsche 911 GT3 R has a fuel capacity of 90 litres. The fuel consumption of GT3 cars is an important factor in racing, as it affects the weight and performance of the car.
In general, GT3 cars are designed to have smaller engines and fuel tanks than other racing cars, such as V8 Supercars. This allows them to have a more balanced power-to-weight ratio and faster lap times. The fuel consumption of GT3 cars can vary depending on various factors such as engine mapping, tyre choice, and driving style. For example, changing the engine mapping can save up to 30% of fuel.
The optimal fuel strategy for a GT3 race depends on the fuel consumption and the ability to maintain tyre life without losing too much time. Starting a race with less fuel can provide a weight advantage, but it may also require more frequent pit stops for refuelling, which can cost valuable time. On the other hand, starting with more fuel can provide a longer window of optimal performance but will also increase the weight of the car.
Overall, the fuel capacity and consumption of GT3 cars are important factors to consider in racing. By optimizing fuel strategies and engine performance, drivers can gain a competitive edge and improve their chances of winning.
