Fuel economy at a glance

These are the EPA's official ratings for the 1986 Cadillac Limousine. 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	18 MPG
City MPG	15 MPG
Highway MPG	22 MPG
Annual fuel cost	$3,300
Tailpipe CO₂	494 g/mi
Fuel type	Regular

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

Driving pattern	Estimated annual fuel cost
Light driver, 7,500 miles per year	$1,650
Average driver, 15,000 miles per year	$3,300
Heavy driver, 25,000 miles per year	$5,500

Specifications

The 1986 Cadillac Limousine runs a 4.1-liter 8-cylinder engine paired with a automatic 4-spd, 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.

Vehicle class: Large Cars
Engine: 4.1L 8-cylinder
Transmission: Automatic 4-spd
Drivetrain: Front-Wheel Drive
Fuel type: Regular
Annual petroleum use: 16.5 barrels per year
