I totally get the gearing taking mph off the top but if these #'s are accurate I don't quite understand the 0-60 time @ 4.2. It just seems to me that if I throw a 3:91 gear in the car, take 300 pounds off her, and have the hp/torque #'s we have been told that it should be sub 4. I know you don't time a road course car from a dead stop so I get it is irrelevant for the purpose of the car but I just find that a bit odd. I am not slamming the car, especially since this is all speculation it just seems to not add up to me.

And...if it has the close ratio gearbox, it likely needs a shift before 60 mph which will make the 0-60 time longer. We have no idea if this speculated information is correct, and if it is, I just don't care. It doesn't matter for those of us who will use the car for its intended purpose. |

Hopefully this will help put to rest the guesses that the Z/28 will cost less than the ZL1 that I see in almost every other thread.

According to GM/Media specifications, the gearbox ratios for the 2014 Z-28 and the 2013 1LE are identical, apparently they are going to use the same TR6060. Also, the first four gear ratios are identical for the ZL1, Z-28, and 1LE, the only difference is gears 5 and 6, with the Z-28/1LE having .74 for 5th, and .50 for 6th, with the ZL1 having .80 for 5th, and .63 for 6th.

Is the final drive gearing known for the Z/28? Sorry if I missed that. |

^, yes thats correct....3.91 rear axle gear ratio, and with 19'' square tire set-up over the 3.73 rear axle gear ratio<standard trans> and 20" tires on the ZL1, with lower fifth and sixth gear's, it's going to be much more of a gear jammer and selective in keeping in the power band for the layout at hand. It's going to be a shifting, high winding wheel mans car for sure...

FWIW I was playing with my EFI live and recorded a 0-60 time of 4.2 with my cam headers and intake on my 11SS, and I'm far from skilled when it comes to launching. I would think the lighter Z28 would have no problem matching it with bigger tires and lighter weight.
