How this compares
At 24 MPG combined, the 2020 Cadillac CT4 ranks 16th of 18 compact cars EPA rated for 2020 — 6 MPG short of the 30 MPG median for that group.
That places it in the lower third of its class. If annual mileage is high, the running-cost gap against a class-average rival compounds quickly.
EPA puts annual fuel spend at about $3,150, $1,075 more than the $2,075 typical for the class. Over five years at 15,000 miles a year that is roughly $15,750, a $5,375 difference against a class-median vehicle.
Tailpipe CO₂ is 373 grams per mile — about 5.6 metric tons over 15,000 miles of driving.
