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. 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-Large Station Wagons class for the 1991 model year is the Buick Century Wagon at 21 MPG.
  • EPA estimates this car costs around $9,500 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 1991 Mercedes-Benz 300TE. 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 17 MPG
City MPG 15 MPG
Highway MPG 20 MPG
Annual fuel cost $4,050
Tailpipe CO₂ 523 g/mi
Fuel type Premium

How the 1991 Mercedes-Benz 300TE compares

The most efficient car in the Midsize-Large Station Wagons class for the 1991 model year is the Buick Century Wagon at 21 MPG. The bar chart below puts the Mercedes-Benz 300TE alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 1991 model year (across all classes) returns 18.7 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 1991 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 premium gasoline, which is $4.61/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 882.4 gallons (the car's annual consumption at the rated MPG).

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $2,025
Average driver, 15,000 miles per year $4,050
Heavy driver, 25,000 miles per year $6,750

Specifications

The 1991 Mercedes-Benz 300TE runs a 3-liter 6-cylinder engine paired with a automatic 4-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.
