One of the most critical factors to consider when purchasing a car, whether used or brand new, is fuel economy. This is important because it determines how much you’ll be spending on fueling your vehicle depending on how often or far you need to drive. In other words, the better the fuel economy of your car, the cheaper your fuel costs will be in the long run, and vice versa. This is hugely important considering how steep fuel prices can get.

Fuel economy is typically calculated and measured in mpg, or miles per gallon. This refers to the distance in miles that a vehicle can cover on one gallon of fuel. Generally, the higher the mpg, the more fuel-efficient a car is. It’s worth noting, however, that a car’s mpg is not fixed and can change depending on factors like traffic and road conditions.

For this reason, the EPA is responsible for certifying car mpg figures and runs tests over standard courses to determine a vehicle’s official mpg. It’s also worth noting that mpg only applies to cars that use gas, not electric vehicles. The latter’s efficiency is measured in miles per charge.

Fuel Economy for Chevy Vehicles

The EPA typically provides each vehicle with three different mpg ratings. These are:

  • Highway mpg: This is a car’s score when driving on an open stretch at high speeds.
  • City mpg: This describes the average a car will get when driving in normal city conditions, starting and stopping at low speeds.
  • Combined mpg: This is the combined average between a car’s highway and city mpg.

Below is a chart detailing the mpg for different Chevrolet cars.

Car Highway.  City   Combined 
Equinox 31 26 28
Silverado 31 23 26
Traverse 27 18 21
Blazer 29 22 25
Trailblazer 33 29 31
Colorado 30 20 23
Malibu 36 29 32
Suburban 27 21 23
Tahoe 28 21 24
Camaro 30 22 25
Corvette 24 16 19
Trax 32 24 27

Which Chevy Vehicle Has the Best MPG?

2022 Chevrolet Spark Red

The most fuel-efficient Chevrolet vehicle is the Chevy Spark, with a city fuel economy of 30 mpg and a highway fuel economy of 38 mpg. This amounts to a combined fuel economy of 33 mpg.

Several factors make the Chevy Spark so efficient regarding fuel consumption. First, the Chevy Spark is powered by a 1.4L ECOTEC four-cylinder engine that delivers 98 horsepower and 94 lb-ft of torque. The large four-cylinder engine helps maximize energy efficiency, thus ensuring that every drop of fuel goes a long way.

Likewise, the size of the Chevy Spark also contributes significantly to its energy efficiency. Smaller cars generally require less energy to run than larger ones, making their fuel requirements much lower. It’s no surprise that the Chevy Spark’s small 93.9-inch wheelbase 93.9 can conserve fuel efficiently.

The Chevy Spark’s 1.4L engine also comes with an airflow sensor that helps regulate the amount of air entering the machine. This controls fuel injection into the engine, thus maximizing fuel efficiency.

Which Chevy Vehicle Has the Worst MPG?

The least fuel-efficient Chevy as of 2022 is the Chevrolet Corvette. With this sports car icon, you can expect a city fuel efficiency of 16 mpg and a highway fuel efficiency of 24 mpg. As with most supercars, the low mpg of the Chevy Corvette is courtesy of its high-powered engine. The Corvette is powered by a 6.2L V-8 engine with an eight-speed dual-clutch transmission. This powertrain delivers a staggering 495 horsepower and 465 lb-ft of torque to its hind wheels.

MPG of Different Categories of Chevy Vehicles

In general, different categories of cars will tend to have varying levels of fuel efficiency, hence different mpg. Here is a brief overview of the mpg of different chevy vehicle categories:

MPG of Chevy Trucks

Let’s be honest, when you think of pickup trucks, regardless of whether they’re midsize or full-size, gas or diesel, the first thing that springs to mind likely isn’t their phenomenal gas mileage. If you’re like most people, you’re probably willing to overlook fuel efficiency for sheer power. However, with Chevy trucks, you don’t have to sacrifice gas mileage for great towing ability since a lot of Chevy trucks come with impressive fuel efficiency.

The Chevy truck with the best mpg presently is the Chevy Silverado which comes with a Duramax turbo-diesel engine. It gets a city fuel efficiency of 23 mpg and a highway fuel efficiency of 31 mpg, which gives it a combined fuel efficiency of 26 mpg. Its smaller cousin, the Chevy Colorado, also performs exceptionally well in gas mileage, with a city fuel efficiency of 20 mpg, a highway fuel efficiency of 30 mpg, and combined fuel efficiency of 23 mpg.

MPG of Chevy SUVs

Chevrolet is a brand revered for manufacturing some of the best full-size SUVs. And while Chevy SUVs are best known for their incredible road presence, some are just as great regarding fuel efficiency. The Chevy Trailblazer, for instance, comes with a highly efficient 1.3L three-cylinder turbocharged engine that gets a city fuel efficiency of 29 mpg, a highway fuel efficiency of 33, and combined gas mileage of 31 mpg.

Another model worth mentioning in the SUV category is the Chevy Equinox, which is powered by a 1.5L turbocharged four-cylinder engine. This larger counterpart of the Trailblazer gets a city fuel efficiency of 26 mpg, a highway fuel efficiency of 31 mpg, and combined fuel efficiency of 28 mpg.

MPG of Chevy Cars

Besides the Chevy Spark, which has the best gas mileage of any Chevy vehicle, plenty of other Chevy cars offer excellent fuel economy. For instance, the Chevy Malibu gets a city fuel efficiency of 29 mpg and a highway fuel efficiency of 36 mpg, averaging a combined gas mileage of 32 mpg.

With fuel prices increasing daily, owning a fuel-efficient car is one of the smartest moves you can make, ultimately saving you thousands of dollars in recurring fuel expenses.
