2022 Porsche 911 Targa 4: MPG and fuel economy

This page collects every fuel-economy figure the EPA publishes for the 2022 Porsche 911 Targa 4. 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.

Fuel economy at a glance

These are the EPA's official ratings for the 2022 Porsche 911 Targa 4. 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).

How the 2022 Porsche 911 Targa 4 compares

The 2022 Porsche 911 Targa 4 returns 20 combined MPG. Cars in the Minicompact Cars class for the same model year average 19.8 MPG, which puts this car ahead of the class average by about 1%.

The most efficient car in the Minicompact Cars class for the 2022 model year is the MINI Cooper Convertible at 32 MPG. The bar chart below puts the Porsche 911 Targa 4 alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2022 model year (across all classes) returns 30.7 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 2022 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 750 gallons (the car's annual consumption at the rated MPG).

Year-over-year MPG for the Porsche 911 Targa 4

The EPA has rated the Porsche 911 Targa 4 across 10 model years, from 2014 Porsche 911 Targa 4 through 2024 Porsche 911 Targa 4. 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.

Combined MPG has stayed in roughly the same range across the run. The peak rating came with the 2017 Porsche 911 Targa 4 at 24 MPG.

Specifications

The 2022 Porsche 911 Targa 4 runs a 3-liter 6-cylinder turbocharged engine paired with a automatic (am-s8), sending power through all-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.

Common questions about the 2022 Porsche 911 Targa 4

Quick answers to the questions people most often search for when looking up the 2022 Porsche 911 Targa 4.

• Is the 2022 Porsche 911 Targa 4 fuel efficient?

  It is in line with the rest of the class. The 2022 Porsche 911 Targa 4 returns 20 combined MPG, and the average car in the Minicompact Cars class for the same model year sits at 19.8 MPG.
• What MPG does the 2022 Porsche 911 Targa 4 get?

  The EPA rates the 2022 Porsche 911 Targa 4 at 20 combined MPG, 18 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 2022 Porsche 911 Targa 4 per year?

  The EPA estimates an annual fuel cost of $3,450 for the 2022 Porsche 911 Targa 4. 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 2022 Porsche 911 Targa 4 require premium gas?

  Yes. The EPA lists the 2022 Porsche 911 Targa 4 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.
• Has the Porsche 911 Targa 4 become more fuel efficient over time?

  Combined MPG has stayed close to flat across the run. Both the earliest (2014 Porsche 911 Targa 4, 22 MPG) and most recent (2024 Porsche 911 Targa 4, 20 MPG) versions sit in the same range.
• How much CO₂ does the 2022 Porsche 911 Targa 4 emit?

  Tailpipe CO₂ emissions are 442 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 6,630 kilograms of CO₂.
• What is the difference between the city and highway MPG of the 2022 Porsche 911 Targa 4?

  City driving returns 18 MPG and highway driving returns 24 MPG, a gap of 6 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 2022 Porsche 911 Targa 4?

  The 2022 Porsche 911 Targa 4 has a 3-liter 6-cylinder turbocharged engine (EPA description: SIDI).
• What transmission and drivetrain does the 2022 Porsche 911 Targa 4 have?

  The 2022 Porsche 911 Targa 4 comes with a automatic (am-s8) transmission and all-wheel drive. All-wheel-drive variants typically read 1 to 3 MPG lower than the front-wheel-drive equivalent of the same engine, since the extra hardware adds weight and parasitic loss.
• How does the 2022 Porsche 911 Targa 4 compare to the best car in its class?

  The most efficient car in the Minicompact Cars class for the 2022 model year is the MINI Cooper Convertible at 32 combined MPG. The Porsche 911 Targa 4 returns 20 MPG, a gap of 12 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
