Fuel economy at a glance

These are the EPA's official ratings for the 2018 Honda Accord Hybrid. 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.

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 47 MPG
City MPG 47 MPG
Highway MPG 47 MPG
Annual fuel cost $1,250
Tailpipe CO₂ 187 g/mi

How the 2018 Honda Accord Hybrid compares

The 2018 Honda Accord Hybrid returns 47 combined MPG. Cars in the Large Cars class for the same model year average 26.5 MPG, which puts this car ahead of the class average by about 77%.

The most efficient car in the Large Cars class for the 2018 model year is the Tesla Model S 75D at 103 MPG. The bar chart below puts the Honda Accord Hybrid 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.

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 319.1 gallons (the car's annual consumption at the rated MPG).

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $625
Average driver, 15,000 miles per year $1,250
Heavy driver, 25,000 miles per year $2,083

Year-over-year MPG for the Honda Accord Hybrid

The EPA has rated the Honda Accord Hybrid across 15 model years, from 2005 Honda Accord Hybrid through 2026 Honda Accord Hybrid. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.

The 2005 Honda Accord Hybrid returned 28 MPG. The most recent 2026 Honda Accord Hybrid returns 48 MPG. That is an improvement of 20 MPG over 21 model years, the kind of gain that usually comes from smaller engines, hybrid systems, or aerodynamic redesigns.

Specifications

The 2018 Honda Accord Hybrid runs a 2-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.
