We also don't know the gear spreads and final drive ratio yet (do we?) so it may just be an engine redline issue, the top in the automatic may just be shorter than the typically very tall T56/T6060 top.

175mph is still very, very serious speed and I have no trouble at all with being 'limited' to that number. I've only knocked on the 155 number a few times with the M5 (and probably most of that time was during the Euro Delivery trip) even though the limiter is now gone.

That's one thing that Cadillac can't quite match, though current Olde Worlde gas prices and exchange rates (and some changes to California use-tax regulations, if the term '91-day rule' means anything to you) make it less appealing than it once was.

A little caddy bashing, yes, but overall I think there is a lot of curiosity!

There are a couple threads over there about the new V - I think it's pretty positive for the most part. There are a couple of brand-loyal guys, but that happens on every board. Even here

We do know the ratios but don't have them handy. Maybe Stealth could run the numbers real quick.

Euro delivery...maybe they'll do a Lansing/Grand Rapids delivery program.


I bet they'll have a V academy available on this one!

The gear ratios are exactly the same as in the A6 and the MN6(non-Z51) of the C6 Corvette. The only difference are the rear end ratio's. The A6 will get a 3.23 compared to a 2.56 in the C6 Corvette. This is a HUGE difference and might explain why the auto is faster( the A6 is geared very strong to begin with which is why the vette can get away with 2.56's.). Alot of the C6 guys are switching to 3.15's and the 08's come with a "2.73 peformance option" rear end. The MN6 will have a 3.73(in the V2) compared to a 3.42 for the C6. Not much of a difference.

There is not much difference between an auto C6 and an MN6 in the qtr. But if you analize the gearing above it becomes readily apparent why I think the A6 will be faster. It's gearing advantage more than overcomes it's weight and RWHP disadvantage. A 3.23 geared A6 vette would most likely walk a 3.42 geared MN6 vette. I see no reason why it should be different with this car........but don't quote me on it.

Torque converters come into play here also. I wonder what the towing capacity of the auto will be? A loose converter means it will not tow anything but have great performance as the loose conv allows the rpms to jump up in the operating range faster.

One reason that the trailblazer SS is not as quick as the GC SRT-8 is it's tight conveter allowing it to tow more than the GC.

Well the one wild card in your analysis is our favorite subject.... traction.

Not a lot of difference from the original auto show specs, 6 hp and 1tq. I guess there wasn't much tuning left for them with that motor after all, at least what they felt safe with.

As far as the top speed difference between the auto and manual, I'll almost certainly never see 175mph, so 191 doesn't matter. The only advantage I could see for the manual would be better Hwy mileage, but won't know how much difference until they release that info.

Nice 0-60 and 1/4 mile times.

Where are you now, non-believers?

Amen Tony ^5. Apparently the weight is not quite the spoiler many people predicted ;-)
