Cadillac ATS MPG Summary

The Cadillac ATS will arrive as a fuel efficient Cadillac.  We live in a fun time, when a high tech four cylinder engine can produce 200+ hp and deliver 30+ mpg on the highway.  A lot of the credit here has to be shared with the light weight and careful design of the Cadillac ATS.

I remember when my 1992 Cadillac STS with 4.9L OHV V8 made 200 hp and weighed more than the new ATS 2.5L Four will weigh.  Now we get equal power from a Four, and with a 6-speed automatic to keep it in its power band!  Also note that in today’s terms, my V8 STS would have been rated 15/23 mpg city/highway versus the 22/32 mpg for the ATS 2.5L!
