I warned you it was government data.

I've always thought the "M" shape to some of those lines is intriguing

The PDF says the Subi is a 2.2L 4 speed auto. The only manual trans is the Corsica. It also says the data is from combined road and dyno testing, so this may be perfect (or better) conditions.

I've been trying to make sense of the data from the 1.8L 4 speed Celica and the 1.6L 3 speed Prizm (very similar engines and Cd) and how/if it relates to my 1.6L 5 speed manual Corolla.
