I worked it out mathmatically. Using 795 revs/mile for that tire (Source=TireRack), at 60 MPH the engine is turning 1857 RPM. It may turn just a tad slower in reality as I have my tire pressures set high, about 49 psi cold on the fronts (may or may not make a difference in revs/mile).
Nice tall highway gearing, for sure, but I find I spend most of my time in 6th even around town. Part of my commute goes through a windy slow stretch along the Ottawa river that has a few gentle grades here and there. Traffic depending, as long as I'm able to keep my speed above 33 MPH (~53 km/h, ~1000 RPM) or so, this little 1.4T lugs the car up through that section with little complaint.
Drop the engine below 1000 RPM or so and torque drops off significantly. I get the feeling cam phasing angles change below 1k RPM to prioritize smooth idling over torque output. I don't think the turbo is contributing at all at those low engine speeds.
For such a heavy car with a small powerplant I can't complain.
