Wait, what? Who designed these cars?

Im confused about how many gears these hypothetical cars have to create the shown peaks and valleys, and why they are so poorly designed. My guess is 1980's GM. Also how does one get 25 mpg’s when stationary? So many questions.

Its 25mpg at 10 mph. The x axis starts at 10 mph

Ah, but the graph starts at 10mph, so that’s first gear. Every positive inflection point should be a shift, correct? So I’m counting 3, or maybe 4 gears. Four speed automatic checks with 1980s GM.

Proof positive school zones are a conspiracy formulated by big oil.

4-speed? Isn’t that awfully optimistic for 80s GM?

I had to write code to generate just such a plot, once. The source car was a ‘96 Taurus.

Ok I agree this is a bad chart but it also sort of jives with my experience. I get stellar gas mileage in my Discovery when overlanding, which is at about 30mph average. Easily get 2 MPG over highway mileage.

The th700r4 came out in the early 80s so it was probably pretty widespread by the end of the decade. I don’t know about their FWD transmissions, though.
