When we talk about fuel efficiency, the term you’ll hear most often is miles per gallon, or MPG. This rating tells you just how far a vehicle can travel on one gallon of gasoline. It can range quite dramatically, from as low as 11 miles per gallon to much higher figures that we’ll explore.
Historically, diesel engines have been known for their superior fuel economy compared to gasoline engines. However, with advancements in technology and shifting consumer preferences, particularly in the US, gasoline engines, especially when paired with hybrid systems, are closing the gap and offering impressive MPG. This guide will walk you through some of the top cars available that boast the highest MPG ratings, covering both gasoline and hybrid options.
Before diving into specific models, it’s important to understand that a car’s actual fuel economy can vary depending on driving habits. Aggressive driving, for example, will decrease MPG, while smoother, more consistent driving will improve it. The MPG figures we’ll be discussing are official average fuel economy ratings, designed to provide a standardized comparison across different vehicles.

5. Hyundai IONIQ – 60.0 MPG
Similar to the Toyota Prius, the Hyundai IONIQ is available in hybrid, plug-in hybrid, and all-electric versions. For maximizing MPG, the plug-in hybrid IONIQ offers compelling value in the used car market.
The Hyundai IONIQ plug-in hybrid combines a 1.6-liter gasoline engine with an electric motor, providing an electric-only range of up to 39 miles on a full charge. This makes it a versatile option for daily driving and longer trips.
Experts highlight the IONIQ’s overall cost-effectiveness, noting that in addition to fuel savings, owners can expect lower insurance and maintenance expenses compared to less efficient vehicles. It also offers a generous list of standard features and a larger cargo area than the Prius, all while maintaining impressive fuel economy.

Maximizing Your Car’s Fuel Efficiency
When selecting your next vehicle, prioritizing fuel efficiency is a smart move. It not only reduces your fuel expenses but also contributes to environmental responsibility.
Modern car engines, especially gasoline engines with hybrid assistance and newer diesel engines, are designed for optimal fuel economy. Turbocharging and hybrid technologies play a significant role in enhancing efficiency across various engine types.
Simple Driving Habits to Boost MPG
Beyond choosing a fuel-efficient car, adopting certain driving habits can significantly improve your vehicle’s MPG.
1) Minimize Air Conditioning Use
Reducing your use of air conditioning can lead to noticeable fuel savings. The air conditioning system places an additional load on the engine, requiring more power and thus consuming more fuel.
2) Drive Smoothly and Steadily
Smooth acceleration and consistent speeds are key to fuel efficiency. On highways, maintaining a steady speed and avoiding sudden acceleration or braking maximizes MPG. Gentle starts from a standstill also reduce engine strain and fuel consumption.
3) Combine Errands and Reduce Short Trips
Short trips, especially when the engine doesn’t fully warm up, are less fuel-efficient. Cold engines operate less efficiently as engine fluids haven’t reached optimal temperatures. Combining multiple errands into a single trip allows the engine to warm up fully and operate more efficiently, saving fuel over time.
