For avid Gran Turismo 7 (GT7) racers, fuel consumption is a critical factor that can significantly impact race strategy and overall performance. Understanding which cars offer the best fuel economy can be the key to securing victory, especially in endurance races. After extensive research and in-game testing, we’ve compiled a comprehensive guide to the Best Car Fuel Consumption rates in GT7, helping you make informed decisions on the track.
Top Fuel-Efficient Cars in GT7 Across Different Groups
To provide a clear picture of fuel efficiency across various car categories in GT7, we’ve broken down the data by Gr.1, Gr.2, Gr.3, Gr.4, and Gr.B classes. Within each group, we present the top cars with the lowest fuel consumption rates, both with and without Balance of Performance (BoP) regulations applied. This distinction is crucial as BoP can alter car performance and fuel efficiency in online races.
Group 1 (Gr.1) Fuel Consumption Leaders
The Gr.1 category features high-performance racing prototypes and hypercars. Fuel efficiency here is paramount for endurance racing success.

The Audi TT Cup ’16 and Honda NSX Gr.4 share the top spot for fuel efficiency under BoP in Gr.4. In No BoP conditions, the Mazda Atenza Gr.4 excels in fuel economy.
Group B (Gr.B) Fuel Consumption
Gr.B rally cars are known for their power and off-road capabilities. While not typically associated with fuel efficiency, understanding their consumption rates is useful for rally-cross events in GT7.
- Ford Focus Gr.B Rally Car (45.69 L/100km)
- Ford Mustang Gr.B Rally Car (45.69 L/100km)
- Hyundai Genesis Gr.B Rally Car (45.69 L/100km)
- Mitsubishi Lancer Evolution Final Gr.B Rally Car (45.69 L/100km)
- Nissan GT-R Gr.B Rally Car (47.12 L/100km)
Notably, many Gr.B rally cars exhibit identical fuel consumption figures, with the Ford models and Hyundai Genesis leading in fuel efficiency within this group.
Testing Methodology for Fuel Consumption Data
To ensure consistent and comparable fuel consumption data, a standardized testing procedure was employed in GT7. The tests were conducted under the following conditions:
- Track: Spa-Francorchamps (Normal Layout)
- Opponent: 1 AI car, Easy difficulty
- Fuel Consumption Rate: 10x
- Tire Wear Rate: 0x
- Start Type: Rolling Start
- Tires: Comfort Soft
- Equal Conditions: ON
For BoP testing, Racing Soft tires were used, and optimal shift points were referenced from external resources to maximize consistency. Cars not listed in the shift point database were driven with best judgment. Fuel consumption for Internal Combustion Engine (ICE) cars was recorded after one full lap.
For electric vehicles (EVs) and unique vehicles like the Chaparral 2X, fuel consumption was tested at a 5x rate until fuel depletion. Distance traveled and the first lap time were recorded to calculate consumption.
The Impact of Engine Modes on Fuel Consumption
Further investigation explored the effect of engine modes on fuel consumption using the Toyota Crown Athlete G ’13 as a test vehicle. The car was tested in various engine states: stock, fully restricted, fully upgraded, and across different engine modes (Mode 1 to Mode 6).
The results revealed that running in engine mode 6 significantly reduced fuel consumption by 38% per lap, albeit at the cost of a 4-second lap time increase. Conversely, a fully upgraded engine increased fuel consumption by 35% but improved lap times by 8 seconds. A fully restricted engine reduced fuel consumption by 55% but resulted in a substantial 19-second slower lap time, indicating a less favorable trade-off for performance.
Conclusion: Mastering Fuel Efficiency in GT7
Understanding car fuel consumption is a crucial element for success in Gran Turismo 7, particularly in longer races and online multiplayer events. This data provides a starting point for racers to select fuel-efficient vehicles and optimize their race strategies.
