RE: Gear ratio
If I can get 2K RPM at highway cruising speeds then 4:10 gear ratio has my vote.
What is real cool are some of the cars do not need shifting into 2nd gear until 60-70 MPH. Mostly because they have a lot of torque and the gear ratio is not too high.
As a result, they beat other cars at the start and win because there a fewer gear changes since they win in 2nd gear.
