X-axis "stretch" means you can stay in a lower gear for longer! Which can *help* acceleration performance.

On a car that will only be operating in a performance envelope of up to ~120mph, I’d rather have the graph stretched vertically (torque multiplication) than horizontally (increasing the mechanical top speed).

From 120 up to ~135mph, you can see that the 2.4 liter with 3.9 gears has a BIG advantage over 2.0 with 4.3 gears, 33% more drive torque to the wheels!

Nice software, btw. Do a version with a 4.3 versus a 3.9.

That IS 4.3 vs. 3.9!
Here's FA20 w/4.3 in black, FA24 w/3.9 in red, FA24 w/4.3 in blue:
