It was just one of several differences. I don't think anyone has quantified any of those things because it's nearly impossible to do a proper A-B-A comparison:

- lighter curb weight (1621 vs 1650 lbs for the LSi)
- no passenger side mirror (OK, that one's easier to estimate)
- different engine computer
- different cam shaft & sprocket
- different piston design (2 vs 3 rings)
- taller final drive
- 49 hp / 58 lbs-ft vs 55 / 58
