This page collects every fuel-economy figure the EPA publishes for the 2018 Toyota Corolla LE Eco. Below you will find the headline combined, city, and highway MPG, the estimated annual fuel cost at three different driving levels, the tailpipe CO₂ emissions, and a full breakdown of the engine and drivetrain. The EPA rates 2 separate variants of this car (different engine, transmission, or drivetrain combinations), and you can compare them side by side in the trims table. If you want to know whether this generation got more or less efficient over the years, the year-over-year table further down covers every model year the EPA has rated.

Key takeaways

  • The most efficient car in the Midsize Cars class for the 2018 model year is the Hyundai Ioniq Electric at 136 MPG.
  • EPA estimates this car saves around $2,000 in fuel over five years compared with an average new vehicle of the same model year.

Fuel economy at a glance

These are the EPA's official ratings for the 2018 Toyota Corolla LE Eco. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

When the EPA tests several variants of the same nameplate (for example, a front-wheel-drive version and an all-wheel-drive version), each gets its own rating. The figures shown here are the headline variant, taken as the configuration with the best combined MPG. The trims table further down covers all 2 variants side by side.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

Combined MPG 34 MPG
City MPG 30 MPG
Highway MPG 40 MPG
Annual fuel cost $1,750
Tailpipe CO₂ 263 g/mi
Fuel type Regular

How the 2018 Toyota Corolla LE Eco compares

The 2018 Toyota Corolla LE Eco returns 34 combined MPG. Cars in the Midsize Cars class for the same model year average 32.6 MPG, which puts this car ahead of the class average by about 4%.

The most efficient car in the Midsize Cars class for the 2018 model year is the Hyundai Ioniq Electric at 136 MPG. The bar chart below puts the Toyota Corolla LE Eco alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2018 model year (across all classes) returns 25.6 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2018 model year is on its own page.

Trim variants rated for 2018

The EPA rates 2 separate variants of the 2018 Toyota Corolla LE Eco. The differences come from the engine size, transmission type, and drivetrain (front-wheel drive, all-wheel drive, and so on). The same nameplate can land several MPG apart depending on the configuration you actually buy.

Engine and transmission Drive Combined City Highway Annual cost
1.8L, 4-cyl, Automatic (variable gear ratios) Front-Wheel Drive 34 MPG 30 MPG 40 MPG $1,750
1.8L, 4-cyl, Automatic (variable gear ratios) Front-Wheel Drive 33 MPG 29 MPG 38 MPG $1,800

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for regular gasoline, which is $3.99/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 441.2 gallons (the car's annual consumption at the rated MPG).

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $875
Average driver, 15,000 miles per year $1,750
Heavy driver, 25,000 miles per year $2,917

Specifications

The 2018 Toyota Corolla LE Eco runs a 1.8-liter 4-cylinder engine paired with a automatic (variable gear ratios), sending power through front-wheel drive.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.
