And what it it was a "competition package" option on the car?

If you have a data point many std. errors away from the expected value, then you have an outlier. Statistics can tell you that accurately. The GTR is an outlier in that sense. That's all the chart/stats is saying. We will probably find out what makes it an outlier in a few weeks.

What I mean is this. power/weight is just one of many factors. We know what many of the other factors are. Tires, suspension, drivetrain. Now if you had hundreds or throustands of data points I would start to believe you did regress the data you meant to. However, you don't have enough data points to eliminate the other factors like tires from influencing the overall trend line.
