ok... so dont activate it during idle, only when cruising
The problem they claim is that it kicks a little when switching, and a torque converter absorbs that
ok....so how bout a computer controlled servo on the clutch to temporarily disengage it while it switches. if it only takes 250milliseconds then it shouldnt be too noticeable
If 6th is really only for economy, it damn well better be good for 65mph at 1000rpm. Those of us trying for high MPG don't need blast-off acceleration in our top gear...my VW revs 3000 at 70mph and accelerates far more than necessary for general highway driving. I usually get into high gear under 30mph unless I'm in a hurry. I've never driven a GM manual transmission but I hope they use tall gears like they do with automatics.
check the spec sheet on the gearing, they are around .5X:1 or something like that for the 5th/6th (dont remember off the top of my head)
50+mpg is territory for a 2000 pound car with 85hp and very low aerodynamic drag (low coefficient of drag AND low frontal area). With the tall 6th as I request above, AFM, and DI, the Camaro could get 35mpg highway, depending on the size of the engine and its torque band...maybe even up to 40mpg with some aerodynamic improvements, but by then it would piss off everyone on this forum.
i know 50mpg isnt totally conceivable, but it could still get higher than the proposed mpg
Making it GM mild hybrid or Prius-like hybrid could help with city mileage, and Volt-like hybrid could help with both city and highway.
i dont see it going hybrid...ever...lol
There's still no torque converter to absorb AFM's kick. It's not like the computer can feather the clutch under load to let AFM switch on and off...that'd be even worse than a little kick from the engine.
not necessarily, the computer can control the clutch in some applications *though the price of such as system i dont even want to fathom* but it wouldnt be that big of a kick, like i said before 250milliseconds is not very long, a quick pulse in the clutch via hydraulic actuatedservo from the cpu hits it just slightly enough to let it slip till the motor switches over
