1986 Peugeot 505 Sedan: MPG and fuel economy
The 1986 Peugeot 505 Sedan is rated by the U.S. Environmental Protection Agency at 26 combined MPG, with 24 MPG in the city and 30 MPG on the highway. That puts it well above the average for cars in the Compact Cars class in the same model year.
This page collects every fuel-economy figure the EPA publishes for the 1986 Peugeot 505 Sedan. 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 6 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 Compact Cars class for the 1986 model year is the Ford Escort FS at 38 MPG.
- The Peugeot 505 Sedan has lost 6 MPG since its first rated model year, the 1984 Peugeot 505 Sedan at 25 MPG. That is often a sign of larger engines or heavier curb weights in newer generations.
- EPA estimates this car costs around $4,750 more in fuel over five years than an average new vehicle of the same model year.
Fuel economy at a glance
These are the EPA's official ratings for the 1986 Peugeot 505 Sedan. 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 6 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 | 26 MPG |
| City MPG | 24 MPG |
| Highway MPG | 30 MPG |
| Annual fuel cost | $3,100 |
| Tailpipe CO₂ | 392 g/mi |
| Fuel type | Diesel |
How the 1986 Peugeot 505 Sedan compares
The 1986 Peugeot 505 Sedan returns 26 combined MPG. Cars in the Compact Cars class for the same model year average 22.4 MPG, which puts this car ahead of the class average by about 16%.
The most efficient car in the Compact Cars class for the 1986 model year is the Ford Escort FS at 38 MPG. The bar chart below puts the Peugeot 505 Sedan alongside the class best and the class average so you can see the full picture.
For broader context, the average new car of the 1986 model year (across all classes) returns 19.8 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 1986 model year is on its own page.
Trim variants rated for 1986
The EPA rates 6 separate variants of the 1986 Peugeot 505 Sedan. 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.
The most efficient configuration on this page returns 26 MPG, while the least efficient returns 18 MPG. That is a spread of 8 MPG between trims of the same nameplate.
| Engine and transmission | Drive | Combined | City | Highway | Annual cost |
|---|---|---|---|---|---|
| 2.5L, 4-cyl, turbo, Manual 5-spd | Rear-Wheel Drive | 26 MPG | 24 MPG | 30 MPG | $3,100 |
| 2.5L, 4-cyl, turbo, Automatic 4-spd | Rear-Wheel Drive | 22 MPG | 21 MPG | 24 MPG | $3,700 |
| 2L, 4-cyl, Automatic 4-spd | Rear-Wheel Drive | 19 MPG | 18 MPG | 22 MPG | $3,150 |
| 2L, 4-cyl, Manual 5-spd | Rear-Wheel Drive | 19 MPG | 18 MPG | 22 MPG | $3,150 |
| 2.2L, 4-cyl, Manual 5-spd | Rear-Wheel Drive | 19 MPG | 17 MPG | 22 MPG | $3,650 |
| 2.2L, 4-cyl, Automatic 4-spd | Rear-Wheel Drive | 18 MPG | 17 MPG | 20 MPG | $3,850 |
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 diesel, which is $5.40/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 576.9 gallons (the car's annual consumption at the rated MPG).
| Driving pattern | Estimated annual fuel cost |
|---|---|
| Light driver, 7,500 miles per year | $1,550 |
| Average driver, 15,000 miles per year | $3,100 |
| Heavy driver, 25,000 miles per year | $5,167 |
Year-over-year MPG for the Peugeot 505 Sedan
The EPA has rated the Peugeot 505 Sedan across 5 model years, from 1984 Peugeot 505 Sedan through 1989 Peugeot 505 Sedan. 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 1984 Peugeot 505 Sedan returned 25 MPG. The most recent 1989 Peugeot 505 Sedan returns 19 MPG. That is a drop of 6 MPG over 5 model years. Newer trims that grow heavier or carry larger engines tend to lose efficiency even as the rest of the lineup improves.
| Year | Combined MPG | Open year page |
|---|---|---|
| 1989 | 19 MPG | 1989 Peugeot 505 Sedan |
| 1988 | 19 MPG | 1988 Peugeot 505 Sedan |

Specifications
The 1986 Peugeot 505 Sedan runs a 2.5-liter 4-cylinder turbocharged engine paired with a manual 5-spd, sending power through rear-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.
