Most of the 177 lb. weight discrepancy can be attributed to the AWD system. If the AWD option box was ticked for the V8 model the added weight could hinder "at speed" acceleration numbers but it could also help improve acceleration from a dead stop. But I wouldn't expect a significant change, up or down, as far as performance goes.
So I don't think there is a large enough performance increase (
at least based on the above example) to make the V8 Stinger an M, AMG or RS competitor. More power (
likely significant) will have to added to the V8 to compete. But the same could happen with the V6 if they so chose.
