Okay, I see what I did. This information isn't readily available on the web, but based on the gear ratios, final drive and tire size (from Ford) I calculate a speed of 24.35 MPH per 1000 RPM in 5th gear for the 2.0 and 26.85 per 1000 RPM for the EcoBoost. That gives 2875 RPM @ 70 MPH for the 2 liter and 2607 @ 70 for the Eco. Does that sound about right?
If I go through this exercise for 4th gear, I get 17.95 MPH/1000 RPM and 3342 RPM @ 60, close enough to what I was seeing. I must have been in 4th gear, I know the lever was down. In my defense, I was on a busy highway in an unfamiliar car, and concentrating more on not getting in an accident than what the tach was reading.
This does not change the fact that when I drove a 2 liter 5 speed car yesterday I found it had more power and delivered that power over a wider RPM range than the peaky Eco. It was just a more pleasing driving experience for me, so I bought it. I had to go 135 miles from home to find a 5 speed car, but I'm happy with the choice I made.
