Can't see the 2-liter 4-pot adding much magic to the relatively large Atlas.
Related Note: I've got a loaner Volvo S60 T5. Drives beautifully, but the new turbo 4 is a soulless little appliance. Ugh.
The questions remaining from that article are that the 2.0T only comes on the FWD drive version, but is tuneable. The VR6 is required for the 4Motion, but since there's no turbo you can't eek much more performance out of it.
