The arrival of the 2013 Cadillac ATS in dealerships marks the completion of the listing of baby Caddy’s engines in the fuel economy area. This popular engine choice has an EPA-estimated rating of 21/31 mpg city/highway with rear-wheel drive and an automatic transmission. With this rating, it’s apparent that the base 2.5-liter four in the ATS is primarily a leader when it comes to costs compared with the 2.0T.
The 2.5 gains only one mpg in the city and two on the highway. As expected, the big 3.6-liter is engine in the ATS range with the highest fuel consumption since it returns only 19/28 mpg. The turbo-four and the V-6 are both offered with all-wheel drive, which lowers the 2.0T’s ratings by one mpg in the city and on the highway. It also drops the 3.6′s rating to 18/26 mpg.
These numbers are for ATS models that have the six-speed automatic. Testing for the six-speed manual in the 2.0T has yet to be done. Cadillac’s 21/31 number for the ATS 2.0T is lower than BMW 328i’s 23/33 rating when it uses an eight-speed automatic. But then, the ATS 2.0T produces an additional 32 hp from its turbo-four compared to the BMW.
The ratings of Cadillac’s new sport sedan don’t exceed those of the BMW but then, the turbo-four ATS has significantly more power than the Lexus IS 250, Mercedes-Benz C250, and Volvo S60 T5. It also offers fuel economy figures that are just about the same as the others. The ATS 2.0T is priced lower than rivals except for the Audi A4 and Volvo S60 T5.
