Cadillac ATS Engine choices

The 3 Series-size Cadillac, codenamed ATS, obviously would get naturally aspirated and breathed-on V-6s, probably of the current 2.8 (but with gas direct-injection) and/or 3.0-liter configurations, and maybe the 3.6. However, Mercedes and BMW are planning to sell C-Classes and 3 Series in the U.S. with four-cylinder engines (and Audi already is there with the A4/A5 2.0 TFSI), so a 2.0-turbo or 2.4-liter four in the ATS wouldn’t be a surprise.

The new, bigger, Alpha-based CTS will stick with 3.0- and 3.6-liter high-feature engines, of course, but given where the competition is looking, a turbo four could be in its future. As we reported before, the Mk III CTS will again be sold only as a sedan, with no coupe or wagon variants. The ATS will get multiple bodystyles instead, including probably a convertible. The bigger question may be whether a small block or a turbo 3.6 powers a next-generation CTS-v.

So sounds like the Cadillac ATS may offer the 260 hp 2L Turbo engine, along with the 3L 270 hp V6 and perhaps a 3.6L at 04 hp? The confusing thing in that mix is why offer the 2L Turbo 4 and the 3L normally aspirated V6 if they make about the same power?

The Gen 3 CTS will be larger and offer the 270hp 3L, 304hp 3.6L, and a 350+ hp TT 3L?
