With gas prices reaching record highs, it's more important than ever to consider fuel efficiency when buying a car. While electric vehicles are an option, they may not suit everyone's budget or driving needs. Hybrid vehicles are the most fuel-efficient, but if you're looking for a traditional internal combustion engine, there are still plenty of fuel-sipping cars available. This paragraph introduces a list of the most fuel-efficient cars, focusing on both hybrid and traditional gas-powered vehicles.

What You'll Learn
Hybrid and electric vehicles
Hybrid Vehicles
- Toyota Corolla: The 2023 Toyota Corolla comes equipped with a 1.8-liter four-cylinder engine that offers excellent fuel economy. It is estimated to achieve around 32-36 miles per gallon (mpg) in the city and 41-43 mpg on the highway, depending on the trim and transmission choice.
- Hyundai Elantra: The Hyundai Elantra achieves an EPA-estimated combined rating of up to 36 mpg. It uses a 147-hp inline-four and a CVT (Continuously Variable Transmission).
- Mitsubishi Mirage: The Mitsubishi Mirage is a highly fuel-efficient and affordable non-hybrid car. It features a 1.2-liter three-cylinder engine with an automatic CVT. While it is not a fast car, with a 0-60 mph time of around 11 seconds, it makes up for it with its fuel efficiency.
Electric Vehicles
- Electric vehicles have motors capable of moving them at any speed within their operational range.
- Electric motors do not consume any power when the vehicle is stopped (idling) and do not require a transmission to keep themselves within the optimal range.
- The efficiency penalty for sizing an electric motor for peak power is not very significant compared to an internal combustion engine (ICE).
- Electric motors have efficiencies ranging from 70% to 95%.

Driving style
Avoid shorter trips
Your engine needs time to warm up, so if you're only driving a short distance, it's likely that your engine will still be cold by the time you return. This is because the fluids haven't had a chance to flow around the engine, which can result in decreased fuel efficiency.
Maintain a steady speed
Keeping your revs and speed as consistent as possible when driving, especially on motorways, can help to maximise fuel economy. When setting off, a smooth acceleration will also reduce the strain on your engine and improve fuel efficiency.
Turn off air-conditioning
Your engine is powering more than you might think behind the scenes, and air-conditioning can add a surprising amount to your fuel usage. Turning off your air-conditioning is an easy way to save a fair amount of fuel.
Choose a fuel-efficient car
Some cars are designed to be more fuel-efficient than others. For example, hybrid vehicles tend to be more fuel-efficient than cars with only a petrol or diesel engine. When choosing a car, you can look for one with a smaller engine or a lower horsepower, as these will generally be more fuel-efficient. Additionally, continuously variable automatic transmissions (CVT) are often more fuel-efficient than traditional manual or automatic transmissions.

Engine size
Generally, a larger engine will consume more fuel than a smaller engine. This is because bigger engines have more space to burn fuel, resulting in higher fuel consumption. For example, a 2-litre engine will consume more fuel than a 1-litre engine with the same amount of petrol. Therefore, if you are aiming to minimise fuel consumption, opting for a smaller engine is generally recommended.
However, there are exceptions to this rule. The type of fuel and the presence of turbocharging can impact fuel efficiency, regardless of engine size. For instance, a diesel engine will typically consume less fuel than a petrol engine of the same size. Additionally, turbocharging can enhance the power of smaller engines, allowing them to accelerate just as well as some larger engines while maintaining better fuel efficiency.
It's worth noting that driving conditions and usage patterns also play a significant role in fuel consumption. If you frequently drive long distances on highways, a larger engine may be more suitable as they excel in maintaining higher speeds without consuming excessive fuel. On the other hand, if your driving is mostly limited to short distances in urban areas with frequent stops and starts, a smaller engine is more efficient as they are designed for better fuel economy in stop-and-go traffic.
In summary, while smaller engines generally consume less fuel, it's important to consider other factors such as fuel type, turbocharging, and your typical driving conditions when selecting a car with optimal fuel efficiency.

Manual vs automatic transmission
When it comes to fuel efficiency, there are a few factors to consider when comparing manual and automatic transmission cars. While manual transmissions have traditionally been more fuel-efficient, modern advancements in automatic transmission technology have narrowed the gap, and in some cases, surpassed the fuel economy of manual cars.
In the past, manual transmissions were known for their superior fuel efficiency. This was partly due to the fact that the engine in a manual car doesn't have to work as hard as an automatic to shift gears. Older manual vehicles, even those just a few years old, tend to have better gas mileage. For example, according to Consumer Reports, as recently as 2015, manual transmissions could offer 2 to 5 more miles per gallon (mpg) than their automatic counterparts. Additionally, manual transmissions were often offered on smaller and more fuel-efficient cars, contributing to their reputation for better fuel economy.
However, starting with model year 2016, improvements in automatic transmission design have made them more fuel-efficient than manuals. Automatics began adding gears more quickly, reducing the stress on the engine and transmission, and thus improving fuel economy. The increased number of gears, along with other design enhancements, have contributed to the improved fuel efficiency of modern automatic transmissions. As a result, some of the latest automatic-transmission designs have surpassed the fuel economy of manuals, offering comparable or even better mpg.
It's worth noting that the availability of manual transmissions is becoming more limited. They are now mainly found on small cars and sports cars, with only a few models exclusively offering manual gearboxes, such as the Honda Civic Type R and the Ford Shelby GT500. On the other hand, many modern sports cars use a dual-clutch automatic transmission, which offers faster shifts and combines the control of a manual with the convenience of an automatic.
While the fuel efficiency advantage of manuals over automatics has narrowed or even reversed in recent years, there are still some potential benefits to choosing a manual transmission. Manuals typically have lower initial costs, with prices that can be $800 to $1,200 less than their automatic counterparts. They also tend to be easier and less expensive to repair due to having fewer moving parts. Additionally, some drivers find driving with a stick shift more engaging and fun.
In summary, while manual transmissions have historically been associated with better fuel efficiency, modern automatic transmissions have made significant improvements in fuel economy. When considering fuel efficiency, it's important to look at the specific make and model of the car, as well as the number of gears and overall design, as these factors can have a significant impact on gas mileage.
