Considering the prototype was the first of three iterations before the SE5 Spyder goes into production, it was already highly evolved and well-functioning. In place of the foot shifter and clutch, there's a little black button that I pushed forward to upshift. I didn't need to roll off the throttle as I shifted. I just pushed the button and the transmission smoothly kicked it up a notch without bucking me like a bronco as it attempted to mesh gears; the sensation was similar to the seamless, continuously variable transmission of a car.Downshifting, I had two options. I could push the button toward me, which required an act of finger contortion, or simply let the SE5 adjust to my slowing speed and downshift for me, which was my preference.
That made me wonder: Why didn't Can-Am just make the thing fully automatic on the upshift also? Mostly it was a matter of cost and efficiency. To make a fully automatic, CVT-type transmission would have required Can-Am to develop an entirely new transmission, instead of just modifying the one it was already using. That in turn would have upped the cost on the SE5 version, which already comes at a $1,500 premium.
