This page collects every fuel-economy figure the EPA publishes for the 2023 Cadillac XT5 AWD. 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 2 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

  • Returns 34% worse combined MPG than the average car in the Small Sport Utility Vehicle 4WD class for the 2023 model year (34.6 MPG class average).
  • The most efficient car in the Small Sport Utility Vehicle 4WD class for the 2023 model year is the Tesla Model Y AWD at 123 MPG.
  • EPA estimates this car costs around $4,250 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 2023 Cadillac XT5 AWD. 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 2 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 23 MPG
City MPG 21 MPG
Highway MPG 27 MPG
Annual fuel cost $3,000
Tailpipe CO₂ 386 g/mi

Trim variants rated for 2023

The EPA rates 2 separate variants of the 2023 Cadillac XT5 AWD. 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.

Engine and transmission Drive Combined City Highway Annual cost
2L, 4-cyl, turbo, Automatic (S9) All-Wheel Drive 23 MPG 21 MPG 27 MPG $3,000
3.6L, 6-cyl, Automatic (S9) All-Wheel Drive 21 MPG 18 MPG 25 MPG $2,850

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

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

Specifications

The 2023 Cadillac XT5 AWD runs a 2-liter 4-cylinder turbocharged engine paired with a automatic (s9), 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 2023 Cadillac XT5 AWD

Quick answers to the questions people most often search for when looking up the 2023 Cadillac XT5 AWD.

  • Is the 2023 Cadillac XT5 AWD fuel efficient?
    Not particularly. The 2023 Cadillac XT5 AWD returns 23 combined MPG, which trails the average car in the Small Sport Utility Vehicle 4WD class for the same model year by about 34%.
  • What MPG does the 2023 Cadillac XT5 AWD get?
    The EPA rates the 2023 Cadillac XT5 AWD at 23 combined MPG, 21 MPG in city driving, and 27 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 2023 Cadillac XT5 AWD per year?
    The EPA estimates an annual fuel cost of $3,000 for the 2023 Cadillac XT5 AWD. 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 2023 Cadillac XT5 AWD require premium gas?
    Yes. The EPA lists the 2023 Cadillac XT5 AWD 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 Cadillac XT5 AWD become more fuel efficient over time?
    Combined MPG has stayed close to flat across the run. Both the earliest (2017 Cadillac XT5 AWD, 21 MPG) and most recent (2026 Cadillac XT5 AWD, 23 MPG) versions sit in the same range.
  • How much CO₂ does the 2023 Cadillac XT5 AWD emit?
    Tailpipe CO₂ emissions are 386 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 5,790 kilograms of CO₂.
  • What is the difference between the city and highway MPG of the 2023 Cadillac XT5 AWD?
    City driving returns 21 MPG and highway driving returns 27 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 2023 Cadillac XT5 AWD?
    The 2023 Cadillac XT5 AWD has a 2-liter 4-cylinder turbocharged engine (EPA description: SIDI). Smaller turbocharged engines like this one tend to deliver bigger-engine power on demand while keeping fuel economy closer to a non-turbo version of the same displacement.
  • What transmission and drivetrain does the 2023 Cadillac XT5 AWD have?
    The 2023 Cadillac XT5 AWD comes with a automatic (s9) 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 2023 Cadillac XT5 AWD compare to the best car in its class?
    The most efficient car in the Small Sport Utility Vehicle 4WD class for the 2023 model year is the Tesla Model Y AWD at 123 combined MPG. The Cadillac XT5 AWD returns 23 MPG, a gap of 100 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
