2008 Cadillac CTS: Fuel Economy Update

April 30, 2009

Cadillac CTS at the test track

We haven't updated our Cadillac CTS' fuel economy in a looooooong time -- updating the fuel log just took me 30 minutes. But here's the damage.

Overall Average: 19.2 mpg
EPA Combined: 20 mpg

Best: 32.5 mpg (Bravo, Scott Oldham)
Worst: 9.9 mpg (Double bravo, Mike Magrath)
Longest Distance on One Tank: 401.2 miles (25.6 mpg by Dan Pund)
Most Fuel in One Tank: 20.598 gallons

(Update: As a sharp reader noted, the CTS only has an 18-gallon gas tank. Not really sure how the 20.598 happened. Maybe someone filled up their lawnmower on the company tab.)
