Rumor has it that it will reach 60mph in 4.7 seconds. Anyone else hear that?

Be careful giving such a large rpm range. 1000rpm versus 1500rpm is a HUGE difference in 6th gear.
Are you telling me that you shift to 6th gear at 45mph? I want you to go do this on your way out to lunch or home from work and tell me you think it is just fine and not lugging the engine.

Where I live we have LONG FLAT roads, Ive done it countless time, I dont make it a habit of cruising around like that. But when you have 5-8 mile to drive at 45MPH on flat road with traffic moving steadily, its fine to do so. If I need to accelerate, I go down a couple gears. To me lugging would be to try to go from 45-75 in 6th at the same rate that you would do it from a lower gear.

In Cincinnati, there is no such thing as a flat road or a straight road -- except Straight Street in the Clifton area. Of course, Straight Street is so steep that even if one has 4-wheel drive and chains, one can't drive up it with two or more inches of snow.

Um, how come nobody corrected the part about a cable drive speedometer??? 
Those haven't been used in most GM cars since the late ~80's / early 90's?!? 
A T56 uses an electrical speed sensor, and I'd bet dollars to donuts that the T6060 does too 
. Since we're into correcting mistakes in this thread and all

If I can get away from language (and I do agree that English is wonderful, and can be very precise, with many synonyms) two points: Way back in the beginning, someone accused GM of underrating HP, and I think that is accurate- the SAE ratings would guarantee a minimum HP rating, i.e., this car produces 'at least' XX HP- Ford and Toyota have both been sued for their (not there, not they're) vehicles not producing advertised HP numbers- hence a motive to rate the HP conservatively- that was claimed on the 4th gen cars, because of identical heads, cams, etc- and GM not wanting to steal the limelight from the Corvette- So, yes, underrating is common, and happens- would you complain if you bought a car that was rated 350 HP and it actually produced 365 HP? Not likely, you would think you got a bargain-
On the cable speedo, and lag- well, two things- by federal law, all speedo are required to be optimistic- they can read high, but never low- you can't be pulled over by a cop for going 65 and say that "my speedo only read 60" However, when your speedo reads 60, you most likely are in fact going 58 or 59- And I haven't seen a cable speedo or odometer in over 2 decades- with the advent of all the electronically controlled transmissions everything uses a vehicle speed sensor, and you change the programing, rather than using different gears in the tail of the transmission matched to the rear axle ratios- used to be they were color coded- they used to even sell adapters for trucks when you went to big tires-
Yeah, V-box rules- it's a GPS world- and I will be 55 this year- been doing this for quite a while- I still know how to set the dwell on points and change the weights in a distributor-

I think that the GXP has a 3:70 rear end compared to the Camaro's 3:45, so that will probably take car of the weight difference. I wish they would have put the 6-speed into the GT, the GXP is just too much $$ and more engine than I would want for my 4 door DD. Esp since it seems to gets much worse mileage.

I claimed that the speedo lagged and when sprinting to 60mph when it registers 60 on the speedo, it isn't there yet.
