I thought it had 260 lb-ft of torque?
Yes, it does, but not over that wide range of rpms. Note the ">" sign...
These days, we frequently see numbers like BMW 335i's 295 lb-ft @ 1200~5000 rpm. That is NOT strictly speaking true. The 335 engine, when dynoed, does not peak until about 2800 rpm and it doesn't peak at 295 lb-ft, more like 340~360 using a 12.5~15% drive train loss conversion factor. This in part explains why 335s are faster than their specs would suggest. However, it is not that BMW is lying, at least not if you take their number to mean "at least" instead of "exactly". You see, the 335's engine does indeed make around 295 lb-ft or more from 1200 rpm to around 5000 rpm. The 1200 rpm part is hard to measure on a dyno, but it is around that much as low as you can measure. BMW advertises the 1200~5000 rpm range -- albeit at a lower torque figure -- because it appears more impressive than 350 lb-ft @ 2800 rpm.
In this case, I guess you can say that the ATS 2.0T will have about 234 by 1500 rpm and keep it above that level until a very impressive 5800 rpm -- a whopping 4300 rpm wide plateau. It will have 260 lb-ft somewhere in there; probably around the low 5000s because that is how you get to 270hp (any higher and you'll blow past 270hp, any lower and it wouldn't add up).
