Riddle me this: Which will accelerate faster in first gear (all things being equal except those listed):

Transmission first gear ratio: 2.84 w/final gear ratio: 3.73
(effective final drive ratio 10.5932:1)

or

Transmission first gear ratio: 3.88 w/final gear ratio: 2.73
(effective final drive ratio 10.5924:1)

In other words, does it matter "where" the torque multiplication takes place (and why)?

Come on, get back to work.
The question, for the first 20 feet, the second choice.

Come on guys, doesn't anyone have any thoughts? :2huh:

In my mind they would accelerate at the same rate, but I'm not sure if that is true.

r429460: If the second one would accelerate faster.... why? :thumbsup:

I'm talking only theory here.

Assume:
Same car, same engine, same one speed transmission (just with the listed different gears), one speed rear end (again, just with the listed different gears), same temperature/humidity, no traction problems, etc.

This is just a question about does it matter acceleration wise "what device" (tranny or differential) does the torque multiplication?

Weight/Mass and Drag

Well, it would make sense to me #2 because even though the final ratio figures to be almost exactly the same, with the gearing early on, that is less weight/mass to spin up to speed since the output shaft/driveshaft/rear gears are all spinning less and the rotational acceleration of those components are lower. That results in less resistance/drag and less parasitic losses.

That's my analysis in a nutshell, but what do I know! :zdunno:
