[MOC] Sequential AWD 4-speed gearbox w/ V8

Sequential AWD 4-speed gearbox with V8 fake engine Features - AWD with center differential - Sequential 4-speed gearbox - One-finger shifter - V8 fake engine This gearbox is an excerpt from my rugged supercar project. The mid-console has an important role in the overall stiffness of that model. It had to be narrow as well. If you build (have built) it, you will also notice it has very little torsional flex. I wanted a 4-speed sequential gearbox covering a wide range of ratios. So not something like 1:2.5 upto 1:1, but rather something like 1:3:5 upto 1:0.8. Another requirement I had, was that I didn't want red clutch gears to transfer drive on axles rotating at different RPM. This is a common practice, but from modding the Porsche I know it induces a lot of friction on the axles involved. When not engaged, red clutch gears better only make dummy rotations and not transfer drive. And finally, all had to fit underneath the engine; I didn't want the gearbox to be routed through the entire chassis. Instructions available on Rebrickable.com. Have fun!
