How this compares

At 25 MPG combined, the 2016 Cadillac CT6 ranks 3rd of 8 large cars EPA rated for 2016 — 2.5 MPG better than the 22.5 MPG median for that group.

That places it a little above the middle of its class. Fuel cost is close enough to its rivals that other running costs will probably matter more.

EPA puts annual fuel spend at about $2,450, $275 less than the $2,725 typical for the class. Over five years at 15,000 miles a year that is roughly $12,250, a $1,375 difference against a class-median vehicle.

Tailpipe CO₂ is 357 grams per mile — about 5.4 metric tons over 15,000 miles of driving.
