Fuel-efficient cars of 2024
With gas prices remaining high and the climate crisis ever-looming, fuel economy is a significant concern for prospective car buyers. While electric cars are an option, they are not always the most practical choice. Many people opt for a hybrid, while some are still attached to ICE vehicles.
The 2024 Mitsubishi Mirage is an affordable and efficient option in a shrinking class of subcompact cars, but its similarly priced rivals are more modern. The Mirage gets a respectable 36 MPG in the city and 43 MPG on the highway, making it a class leader in fuel economy. However, this victory isn't enough to save the little Japanese hatchback, which is set to disappear in 2025 in North America.
The 2024 Nissan Versa is another ridiculously economical option without a hybrid powertrain. In the city, the Versa will clock around 32 MPG, increasing to 40 MPG on the highway, for a combined 35 MPG.
The compact 2024 Toyota Corolla offers sedan and hatchback body styles, front- or all-wheel drive, and a hybrid powertrain. The Corolla Hybrid achieves 53 MPG in the city and 52 MPG on the highway, allowing drivers to save significantly on fuel costs without sacrificing reliability or comfort.
The 2024 Honda Accord Hybrid sets the bar high for mid-size sedans with its combination of fuel efficiency, luxury, and technology. With 48 MPG in the city and 47 MPG on the highway, the Accord Hybrid provides impressive mileage for a larger sedan. It also offers a refined driving experience, spacious seating, and a quiet cabin.
The 2024 Chevrolet Bolt EV is one of the most affordable all-electric cars on the market, offering an impressive 131 MPGe in the city and 109 MPGe on the highway, with a range of up to 259 miles on a full charge.
For SUV lovers, the 2024 Ford Escape Hybrid is a solid choice, offering 44 MPG in the city and 37 MPG on the highway. The 2024 Toyota Grand Highlander Hybrid is another option, achieving a respectable 35 MPG combined.
Other fuel-efficient cars to consider in 2024 include the Toyota Prius, the Hyundai Elantra, the Volkswagen Golf R, and the Volkswagen GTI.

Fuel efficiency is one of the most important factors to consider when buying a new car. While most modern vehicles are more efficient than older models, some cars outperform others. Here are some of the most fuel-efficient cars of 2025:
Honda CR-V
The Honda CR-V is a popular choice for buyers seeking a reasonably priced, family-friendly SUV.

Tips to improve fuel efficiency
Fuel efficiency depends on a variety of factors, including the car, the driver, and the driving conditions. Here are some tips to improve fuel efficiency:
Choose an efficient car
Firstly, when choosing a car, opt for one with good fuel efficiency. Many modern cars are far more efficient than older models due to advancements such as turbochargers and hybrid technology. For example, the 2024 Toyota Prius is known for its high fuel economy, offering 57/56/57 mpg. The Hyundai Elantra Hybrid and Kia Niro Hybrid are also good options, with 51/58/54 mpg and 53/54/53 mpg, respectively.
Maintain your vehicle
Ensure your tires are inflated to the recommended pressure. Underinflated tires can increase fuel consumption by up to 10%. Remove any unnecessary items from your car, as every extra 50 kg reduces fuel efficiency by 2%.
Adapt your driving style
Drive smoothly and steadily to reduce strain on the engine. Avoid heavy acceleration and try to maintain a constant speed. Use cruise control if your car has it, and when driving a manual car, stay in a higher gear when appropriate. When approaching a hill, start accelerating before you reach it, rather than when you're already on it. Plan your route to avoid stop-start traffic, which can burn more fuel.
Use air conditioning wisely
Using air conditioning can increase fuel consumption, so it's best to turn it off when possible. However, when driving at high speeds (over 60 mph), it's more fuel-efficient to use the air conditioning than to open the windows, due to reduced wind resistance.
Plan your trips
Avoid taking your car for very short trips, as the engine may not have time to warm up and reach its optimal operating temperature. This results in lower fuel efficiency.
Reduce weight and drag
Remove roof racks or boxes when not in use, as they increase drag and reduce fuel efficiency. Try to minimize the weight of the car by removing unnecessary items from the trunk or backseat.

Fuel economy ratings
In the US, the Environmental Protection Agency (EPA) provides data and ratings on the fuel efficiency of vehicles. The official US government source for fuel economy information is FuelEconomy.gov, which is administered by the Oak Ridge National Laboratory for the US Department of Energy and the EPA. The website provides information on vehicle fuel economy, including current emissions regulations, automotive trends, and details on a new car's window sticker.
The EPA data is used to rank vehicles according to their fuel efficiency. For example, the 2024 Toyota Prius is rated highly for its fuel economy, achieving 57/56/57 mpg, and up to 196 horsepower. The Hyundai Elantra Hybrid is also rated highly, achieving 51/58/54 mpg. The Kia Niro Plug-In Hybrid, with its 1.6-litre engine and two electric motors, is another fuel-efficient option.
Other vehicles with good fuel economy include the Honda Accord, which is praised for its spacious cabin, refined road manners, and first-rate build quality; the Lexus ES, a reasonably priced mid-size luxury sedan with a plush interior; and the Toyota Corolla, which offers a 169-hp, 2.0-litre four-cylinder engine and is rated at 32/41/35 mpg.
