Fuel economy at a glance
These are the EPA's official ratings for the 1988 Porsche 944 S. 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 | 19 MPG |
| City MPG | 17 MPG |
| Highway MPG | 24 MPG |
| Annual fuel cost | $3,650 |
| Tailpipe CO₂ | 468 g/mi |
| Fuel type | Premium |
How the 1988 Porsche 944 S compares
The 1988 Porsche 944 S returns 19 combined MPG. Cars in the Minicompact Cars class for the same model year average 23.8 MPG, which puts this car behind the class average by about 20%.
The most efficient car in the Minicompact Cars class for the 1988 model year is the Chevrolet Sprint Metro at 47 MPG. The bar chart below puts the Porsche 944 S alongside the class best and the class average so you can see the full picture.
For broader context, the average new car of the 1988 model year (across all classes) returns 19.5 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 1988 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 789.5 gallons (the car's annual consumption at the rated MPG).
| Driving pattern | Estimated annual fuel cost |
|---|---|
| Light driver, 7,500 miles per year | $1,825 |
| Average driver, 15,000 miles per year | $3,650 |
| Heavy driver, 25,000 miles per year | $6,083 |

Specifications
The 1988 Porsche 944 S runs a 2.5-liter 4-cylinder 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.

-
Is the 1988 Porsche 944 S fuel efficient?
Not particularly. The 1988 Porsche 944 S returns 19 combined MPG, which trails the average car in the Minicompact Cars class for the same model year by about 20%. -
What MPG does the 1988 Porsche 944 S get?
The EPA rates the 1988 Porsche 944 S at 19 combined MPG, 17 MPG in city driving, and 24 MPG on the highway. Real-world numbers depend on your driving style, the weather, and how loaded the car is. -
How much does it cost to fuel a 1988 Porsche 944 S per year?
The EPA estimates an annual fuel cost of $3,650 for the 1988 Porsche 944 S. That figure assumes 15,000 miles of driving per year, a 55% city and 45% highway split, and the EPA's published average fuel price for the rated fuel grade. -
Does the 1988 Porsche 944 S require premium gas?
Yes. The EPA lists the 1988 Porsche 944 S as requiring premium gasoline. Running it on regular can reduce performance and may affect engine warranties, so it is not a recommended way to save at the pump. -
How much CO₂ does the 1988 Porsche 944 S emit?
Tailpipe CO₂ emissions are 468 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 7,016 kilograms of CO₂. -
What is the difference between the city and highway MPG of the 1988 Porsche 944 S?
City driving returns 17 MPG and highway driving returns 24 MPG, a gap of 7 MPG. A spread that wide is typical of cars with conventional automatic or manual transmissions, where stop-start city traffic eats more fuel than a steady highway cruise. -
What engine is in the 1988 Porsche 944 S?
The 1988 Porsche 944 S has a 2.5-liter 4-cylinder engine (EPA description: (FFS)). -
What transmission and drivetrain does the 1988 Porsche 944 S have?
The 1988 Porsche 944 S comes with a manual 5-spd transmission and rear-wheel drive. -
How does the 1988 Porsche 944 S compare to the best car in its class?
The most efficient car in the Minicompact Cars class for the 1988 model year is the Chevrolet Sprint Metro at 47 combined MPG. The Porsche 944 S returns 19 MPG, a gap of 28 MPG. If you are comparing on fuel economy alone, the class leader is worth a look. -
How much more does the 1988 Porsche 944 S cost in fuel compared to an average car?
The EPA estimates that over five years, the 1988 Porsche 944 S will cost about $7,500 more in fuel than an average new vehicle of the same model year. The difference accumulates because the car uses more fuel per mile, not because of any one-off charge at the dealership.
