The idea behind it of course is great but I've got doubts there'll ever be a decent implementation.
Since the idea behind CVT is to keep the engine at max torque regardless of output shaft velocity (ie: vehicle speed), yes that's brilliant. Which makes me wonder what in hell MS was on about back there.
But it doesn't for two reasons.
1. technically, most are tuned for max EFFICIENCY, which while in theory is where max torque is, if you lead-foot the gas in an emergency situation, it'll still rise above the, say, 3000rpm.
2. There is always a climb from no torque, to max torque every acceleration. (from 600rpm idle to 3000rpm), so this is where you feel shudder.
Bonus 3. They give drivers flappy paddles to 'limit' the gearbox manually if wanted (bad idea).
Lets not even look at the problems with running an engine at near the exact same RPM for its entire life. No visits to redline at all must mean hella amounts of carbon.
