Fuel economy at a glance

These are the EPA's official ratings for the 2008 Cadillac SRX 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 17 MPG
City MPG 14 MPG
Highway MPG 22 MPG
Annual fuel cost $3,500
Tailpipe CO₂ 523 g/mi

Trim variants rated for 2008

The EPA rates 2 separate variants of the 2008 Cadillac SRX 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
3.6L, 6-cyl, Automatic (S5) 4-Wheel or All-Wheel Drive 17 MPG 14 MPG 22 MPG $3,500
4.6L, 8-cyl, Automatic (S6) 4-Wheel or All-Wheel Drive 15 MPG 13 MPG 20 MPG $4,600

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 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 $1,750
Average driver, 15,000 miles per year $3,500
Heavy driver, 25,000 miles per year $5,833

Specifications

The 2008 Cadillac SRX AWD runs a 3.6-liter 6-cylinder engine paired with a automatic (s5), sending power through 4-wheel or 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.
