Everybody is praising the driving dynamics of the Cadillac ATS and CTS sedans, and while the latter already has a sporty version that puts its chassis to the test, the former doesn’t yet, and speculation as to what might power it continues.

To us, it would seem natural for GM to give the sportier ATS the same 3.6-liter twin-turbo V6 as you get in the CTS Vsport, an engine that makes 420 hp, and could probably be tuned to give the smaller sedan/coupe BMW M3/M4 rivaling horsepower figures.

Now, a report uploaded by Automobile suggests that this may very well not be the case, and while the ATS-V would still get its power from a twin-force-fed V6, it would be a different one of smaller displacement – a new 3.2-liter unit derived from the same basic architecture that also stood as the basis for Alfa Romeo’s 3.2 JTS motor.

Apparently, the displacement change is justified in order to allow for its tuning upwards of 500 hp, seriously surpassing what BMW plans to offer. If you ask me, this seems a bit unlikely and not very realistic, but since they are mere rumors, we won’t comment on their accuracy just yet.
