[ASKED] Manual Transmission Gearing
I have a great quesiton for Tadge as I've seen this on both the C7 and the C6:
/question/
On the manual transmisison Corvette (C6 & C7 included), what thought goes into how the specific gear ratios are spaced? I used to own a C6 and currently own a C7; both manual. In both generations, the Z51 package has short gearing for 1st thru 3rd gear. When you get into 4th gear the RPMs drop considerably as it is such a long pull.
On both models 3rd gear hits red line at approximately 100 MPH. 4th gear then makes a pull all the way to just under 150 MPH. As speed builds, the aerodynamic drag increases exponentially.
With that said why are there so many overdrive gears? I understand using the top most gear in their respective generations as an overdrive gear for fuel economy but closer spacing to match the lower gears would have likely gained better acceleration in the 100-150 MPH range.
