Fuel Efficiency and Gas Mileage

I've been driving my '18 CTS with the 3.6L V6 and I'm consistently getting around 25mpg in city driving and 32mpg on the highway, not too shabby for a larger sedan

I'm surprised by how little attention has been given to the fuel efficiency of modern Cadillacs. The CT6 V-Sport's estimated 18mpg combined is quite low considering its size and power output. What are your thoughts on this?

I recently purchased a 2022 CT5 and was surprised to see an improvement in fuel efficiency with the new engine technology. On average I'm getting around 27mpg combined which is impressive considering it's a V6. Overall happy with the performance and fuel economy.
