What You'll Learn
Fuel efficiency of sports cars depends on driving style
Sports cars are designed to be powerful and fast, which often means they are less fuel-efficient than other vehicles. However, the fuel efficiency of a sports car is not solely determined by its design and specifications. The driving style and habits of the person behind the wheel can also have a significant impact on how much fuel a sports car consumes.
Aggressive driving, such as rapid acceleration, high speeds, and frequent lane changes, can lead to increased fuel consumption. On the other hand, adopting a more conservative driving style, such as maintaining a steady speed and avoiding sudden stops and starts, can help improve fuel efficiency. For example, the Mini Cooper Hardtop two-door is one of the most fuel-efficient vehicles in its class, thanks to its aerodynamic design. However, its fuel economy can still be significantly impacted by how it is driven.
The type of driving also matters. For instance, driving in sport mode or on a race track will likely result in higher fuel consumption than driving in normal mode or on city streets. This is because, in sport mode, the car is already in a lower gear, requiring less throttle for acceleration but resulting in higher fuel usage. Similarly, driving on a track may involve reaching higher speeds and experiencing more air resistance, which can decrease fuel efficiency.
The choice of transmission can also impact the fuel efficiency of a sports car. Traditionally, manual transmissions were considered more fuel-efficient than automatic transmissions. However, with advancements in technology, this is not always the case anymore. Some modern automatic transmissions, such as the eight-speed automatic in the 2025 Toyota GR Corolla, are designed to improve fuel economy. Additionally, the number of gears can play a role, with a seven-speed automatic transmission in the Mercedes-Benz SLK250 delivering 23 miles per gallon in the city.
Lastly, the type of fuel used can also make a difference. Premium gas may help a car run more efficiently, but it is typically more expensive. Using a lower grade of gas may save money, but it could also result in reduced fuel efficiency.
In conclusion, while the mechanical specifications of a sports car play a significant role in its fuel efficiency, the driving style and habits of the driver can also have a substantial impact. By adopting more conservative driving practices and choosing vehicles with efficient transmissions, it is possible to improve the fuel economy of sports cars without compromising their performance and fun factor.

Smaller engines are more fuel-efficient
Sports cars are designed with performance in mind, and fuel efficiency often takes a back seat. However, some sports cars are surprisingly fuel-efficient, and a few factors can help improve gas mileage. While engine size is not the sole determinant of fuel efficiency, smaller engines are generally more fuel-efficient than larger ones. This is because a smaller engine needs to operate at a higher RPM and in lower gears to achieve the same power output as a larger engine, which wastes fuel.
A smaller engine, in general, will have better fuel efficiency than a larger one, assuming all other factors are equal. This is because a larger engine will produce more power per revolution, and thus will not have to work as hard as a smaller engine to achieve the same output. However, this advantage can be offset by other factors such as torque, crank throw, conrod length, and the number of cylinders, which can all impact fuel efficiency.
For example, the 2020 Volkswagen GTI, with its small engine, delivers 24 miles per gallon in city driving. The 2025 Subaru BRZ, another car with a small engine, boasts an EPA-estimated 25 mpg combined in city/highway driving. The 2025 Toyota GR86, with its 228-horsepower four-cylinder engine, also offers excellent fuel efficiency. These cars demonstrate how smaller engines can lead to better fuel economy.
However, it's important to note that simply having a smaller engine does not guarantee better fuel efficiency. The overall design and specifications of the car play a significant role. For instance, a small engine in a large, heavy car may struggle to achieve optimal fuel efficiency due to being overworked. Similarly, driving style can significantly impact fuel consumption, with aggressive driving leading to higher fuel usage.
When considering fuel efficiency, it's worth looking beyond engine size. Modern engine technology and transmission design have a significant impact. For example, the 2025 Honda Civic Type R features a turbocharged four-cylinder engine with a six-speed manual transmission, delivering impressive fuel efficiency. The 2025 Mustang, with its 10-speed automatic transmission, achieves up to 33 mpg on the highway, showcasing how advancements in transmission technology can enhance fuel economy.

Automatic transmissions are more fuel-efficient than manual
While it was once true that manual transmissions were more fuel-efficient than automatics, this is no longer the case. Modern automatic transmissions tend to be heavier than manual transmissions, which increases the overall weight of the car and reduces its fuel efficiency. However, the weight difference is relatively small, and automatic transmissions with advanced features such as stop-start technology and adaptive cruise control can be more fuel-efficient than their manual counterparts.
For example, the 2022 Subaru Crosstrek with a 2.0-litre engine and a six-speed manual transmission gets an EPA-estimated 25 miles per gallon in mixed-driving conditions. However, the continuously variable automatic transmission (CVT) version of the same car, with the same 2.0-litre engine, is estimated to get 30 mpg in mixed driving—a 20% improvement.
The 2024 Nissan Z is another example of a car with better fuel economy estimates with an automatic transmission (22 mpg) compared to the standard manual transmission (20 mpg). Similarly, the V6-powered Camaro has an EPA-estimated fuel efficiency of 20 mpg with the standard manual transmission, but this number increases to 22 mpg with the automatic transmission.
The Ford Mustang is another example of a car that has become more fuel-efficient with the introduction of an automatic transmission. The 2025 Mustang comes standard with a 315-horsepower turbocharged four-cylinder engine and a 10-speed automatic transmission, which provides up to 33 mpg on the highway.
In addition to improved fuel efficiency, automatic transmissions are generally found to be easier to drive than manual transmissions. However, manual transmissions are often cheaper, which makes them more popular with new drivers. Ultimately, the decision between a manual and automatic transmission depends on various factors, including personal preference, budget, and specific vehicle requirements.

Lighter sports cars have better fuel efficiency
Reducing a vehicle's weight can lead to notable improvements in fuel efficiency. According to the Department of Energy, a 10% reduction in vehicle weight can result in a 6% to 8% increase in fuel economy. This principle applies to both conventional and hybrid vehicles. For example, using aluminum instead of steel in the body of a car can make it 10% to 40% lighter, leading to potential fuel savings of about 10%.
Automakers are increasingly recognising the benefits of lightweight materials in improving fuel efficiency. Luxury car brands like Audi have been utilising lightweight materials for years to maintain horsepower while incorporating larger powertrains. Additionally, BMW has invested significantly in carbon fiber, employing it in the construction of the i3 and i8 electric vehicles. Carbon fiber is approximately 50% lighter than steel and 20% lighter than aluminum, offering enhanced strength and weight reduction.
The benefits of lightweight vehicles extend beyond fuel efficiency. Lighter cars contribute to a reduction in greenhouse gas emissions, promoting a cleaner environment. They also tend to have lower operational costs due to reduced fuel consumption. Furthermore, advancements in crash safety technologies have addressed concerns about the safety of lighter vehicles, with stricter safety standards and the inclusion of safety features like airbags.
In summary, lighter sports cars generally exhibit better fuel efficiency due to their reduced weight. This weight reduction can be achieved through the use of lightweight materials such as aluminum and carbon fiber. The increased fuel efficiency of these vehicles not only offers financial benefits but also contributes to a more sustainable and environmentally friendly transportation system.
