Car tuning is a way to increase a vehicle's performance and efficiency. While it is possible to tune a car for better fuel efficiency, there are many factors to consider, and it may not always be the best option. For example, while chip tuning can increase fuel efficiency, it often comes at the cost of increased emissions. Additionally, car engines are typically tuned to strike a balance between fuel economy and power to appeal to a wide range of customers. This means that the default settings are usually already optimised for fuel efficiency to a certain extent.

What You'll Learn
A stiffer suspension improves fuel economy
Upgrading to a stiffer suspension system can improve fuel economy. Firstly, a loose suspension system causes a car to shake and rumble, requiring the engine to work harder to maintain the desired speed, which in turn uses up more fuel. By tightening the suspension or upgrading the system, the car remains level, and the engine doesn't have to work as hard.
Additionally, wheel alignment impacts fuel economy. Misaligned wheels cause the engine to expend more fuel to keep the car moving at the desired speed. Upgrading the suspension system improves wheel alignment, reducing the amount of fuel used.
The impact of suspension on fuel economy is also noticeable when cornering. A stiffer suspension setup reduces or eliminates the need to brake before taking a corner, saving energy. A softer suspension would require a driver to slow down more before cornering to account for body roll, which would use more fuel to accelerate back up to speed.
While some sources argue that a softer suspension setup would be more fuel-efficient as it would result in less energy lost compressing the suspension, the energy saved is negligible. Ultimately, the biggest payoff in fuel consumption is driving style, with a steady throttle opening making a 10-20% difference in fuel economy.

Driving style is the biggest factor in fuel consumption
There are several ways to modify driving styles to reduce fuel consumption. For example, accelerating more gradually can contribute to fuel savings. This is because the deceleration process of vehicles is decisive for fuel consumption under different conditions. Eco-driving, which refers to a driving style that emphasizes fuel efficiency, is another way to lower vehicle fuel consumption. It is estimated that eco-driving can result in energy and greenhouse gas emission reductions of 5–15%.
Another way to reduce fuel consumption is to avoid warming up the engine before driving. This process wastes fuel and causes more wear on the engine. Similarly, long periods of idling increase fuel consumption and should be avoided. Instead, it is recommended to use the cruise control function (if equipped) to maintain a steady throttle opening, which can make a 10-20% difference in fuel economy.
Other recommendations to improve fuel economy include shifting as early as practical while accelerating and using the highest possible gear while coasting or cruising. Additionally, maintaining reasonable highway speeds and anticipating traffic conditions to minimize hard braking can help reduce fuel consumption. These driving techniques can be taught in classes and have been made a mandatory part of driver's education in some countries.

Spark plugs can decrease fuel efficiency by 20%
While there are many factors that can decrease fuel efficiency, one of the most significant is the condition of the spark plugs. Spark plugs play a crucial role in the engine's combustion process, and when they are not functioning optimally, it can lead to a noticeable drop in fuel efficiency.
The primary function of spark plugs is to create an electric spark, which ignites the air-fuel mixture in the engine's combustion chamber. Over time, spark plugs can become dirty or worn out, which can lead to incomplete combustion and misfires. In fact, according to AAA, it is during the last 20% of a spark plug's life that misfires and incomplete combustion occur most frequently. This can result in a significant decrease in fuel efficiency, causing your vehicle to use up to 20% more fuel than necessary.
By replacing your spark plugs before they reach the end of their lifespan, you can prevent these issues and maintain optimal fuel efficiency. Additionally, proper maintenance of spark plugs can also improve engine performance and reduce the need for costly repairs. It is recommended to change your spark plugs at regular intervals and to choose high-quality replacements that are suitable for your specific engine.
Furthermore, it is worth noting that the gap between the spark plug electrodes can also impact fuel efficiency. A properly gapped spark plug will burn hot and efficiently, while a gap that is too small or too large can lead to insufficient combustion or a weak spark. As such, it is important to refer to the manufacturer's recommended gap settings and to make adjustments as needed based on your specific engine and driving conditions.
In conclusion, spark plugs play a crucial role in maintaining optimal fuel efficiency. By replacing them at the appropriate intervals and ensuring they are properly gapped, you can prevent a significant decrease in fuel efficiency and keep your vehicle running smoothly and efficiently.

Dirty air filters can reduce fuel economy by 10%
While car tuning can lead to small efficiency gains, a key consideration when it comes to fuel economy is the condition of your car's air filter. A dirty air filter can significantly impact fuel efficiency, leading to a reduction of up to 10% in fuel economy.
Air filters play a crucial role in trapping contaminants and preventing them from entering the engine. Over time, the filter media, made of paper and synthetic fibers, becomes clogged with dirt and debris. This restricts airflow and prevents the engine from breathing properly, resulting in decreased engine performance and increased fuel consumption.
The impact of a dirty air filter is more pronounced in older vehicle models. Modern, fuel-injected engines are less sensitive to dirty air filters due to the use of sensors and onboard computers that adjust engine operation. However, even with these advancements, a severely clogged air filter can still impact fuel economy.
To maintain optimal fuel efficiency, it is essential to regularly inspect and replace your air filter when necessary. A clean air filter ensures a steady supply of dense, fresh air, which improves engine performance and reduces the need for aggressive acceleration, further contributing to increased fuel economy.
Additionally, other factors such as driving style, engine maintenance, and vehicle aerodynamics also play a significant role in fuel economy. By combining proper maintenance, including air filter replacements, with efficient driving habits and optimal cruising speeds, you can maximize your vehicle's fuel efficiency and minimize fuel consumption.

Engine chip tuning can increase fuel efficiency
Chip tuning involves modifying the settings of the engine control unit (ECU) to optimize various parameters, such as fuel and ignition events, cam timing, and air-to-fuel ratios. By fine-tuning these settings, it is possible to improve fuel efficiency, especially when combined with responsible driving practices.
For example, the RaceChip app offers three tuning modes: Efficiency, Sport, and Race. The Efficiency mode is specifically designed to save fuel in urban traffic by optimizing torque and allowing for earlier gear shifts, resulting in less frequent shifting and lower fuel consumption. Additionally, chip tuning can increase the efficiency of fuel injection and combustion, further contributing to improved fuel efficiency.
It is worth noting that while chip tuning can enhance fuel efficiency, it may also increase emissions. The impact on emissions can vary depending on the specific modifications made and the type of engine. In some cases, such as the FIRE engine from FIAT, efforts to improve fuel efficiency led to increased NOx emissions. Therefore, it is essential to consider the potential trade-offs between fuel efficiency and emissions when considering chip tuning.
Moreover, driving style plays a significant role in fuel economy. Maintaining a constant throttle opening, using cruise control, shifting to higher gears early, and avoiding extended idling can all contribute to improved fuel efficiency, regardless of whether chip tuning is implemented.
