First - there's the power. Okay - this is where, if anywhere, I would have any worry or concern about performance. While I think ZL1 might get up to about 580 horsepower, I'm not sure if that's enough staying power to keep fighting off the GT500 until the end of it's run for this generation. I don't know if I believe reports of 620 horsepower, however, I believe replacing the current Eaton with the newer 2300, it would be pretty easy to get to 600. Would I care if there was a 20 horsepower disparity? No - considering the following. Besides, I'll be pushing my warranty anyways, lol.

Next - the chassis. New generation Electric Power Steering (EPS) and next generation Magnetic Ride (MR) suspension systems, in addition to the newly announced Performance Traction Management (PTM). While the GT500 already posesses this feature, EPS would impart ZL1 with similar tunability from the engineers to maximized feel and handling. The MR is something the competition doesn't have and allows track settings for all-out fast times and a touring-type ride for on your way home. Look how effective this feature is on GM's other two top rides: ZR1 and CTS-V. They pretty much OWN nearly all cars in their respective segments and price ranges. The closest car to ZR1 is the GTR if I understand correctly and the improvements to the '12 ZR1 should pretty much keep it at bay and only the Panamera is faster around the 'Ring than CTS-V, and it's something like nearly twice as much money. PTM is another feature on ZL1 that will make the most of the power available from ZL1's LSA. This is a reason I'm not too worried about the GT500. These three systems, working together, are going to be quite formidable for any car in ZL1's price point.

Furthermore - powertrain. While ZL1 may be giving up in 4-digit power potential with it's LSA, OEM power should be great. In addition, from the balancer back, it's going to be built to take the abuse. While not many details have been confirmed by GM, recently, we've seen a tiny bit of the cast iron differential case on ZL1. Comparing it's relative size to respective SS differential cases, it's reasonable to extrapolate that it's ring and pinion are going to be seriously strong. While there's no confirmation on the exact size, members have stated it's a 14-bolt ring and pinion, which in truck terms, meant either a 9.5" or 10.5" ring gear. For those that don't know, those were used in 3/4 and 1-ton pickup trucks. There's no confirmation, but I think the extrapolation is sound. In addition, we've seen one axle shaft and a member reported it was the "small" one. It's spline count wasn't announced, but it looks probably in the neighborhood of the low-to-mid 30s, which is highly desirable for strength.

Finally - aerodynamics, brakes, and tires. GM's stated a deliberate effort was made to tune aerodynamics and DOWNFORCE for ZL1. What this will translate to, is using more of that LSA power around and down the track or the strip. Pushing that car down will impart more tire friction and result in higher grip from the new Generation II F1s. The are still working with Goodyear (from what I've gathered) and a lighter and wider wheel and tire package (from SS) will impart greater available traction and allow to carry the speed into and out of the corners more effective. The 6-piston front calipers, along with the 0.5" larger rotors will bleed the heat off better and stave off brake fade more effectively.

GM's stated many times that they don't want to be equal to the competition - they want to dominate. With the improvements to the '12 V6s, the upgrades for SS, and the introduction of ZL1, I believe they are completely serious. For a person to have an opinion otherwise on a CAMARO website confuses me, so I could've just wasted the last half hour with all the crap I posted above. Take it or leave it. I'll spend my money where I like, like everyone else. Just don't come into this Section, with the attitude it seemed like you had, and not expect some flames.

Over-and-out.
Wasted? Noo...

I quite enjoyed reading that post! More than I have in a very long time!

Thumbs up 2012 Chevrolet Camaro ZL1 Gets Optional Six-Speed Automatic Transmission

Link to this article in Motor Trend appeared on the Camaro Facebook page this morning:

http://wot.motortrend.com/2012-chevr...ion-86545.html

Buyers who opt for the high-performance 2012 Chevrolet Camaro ZL1 will now have a choice between automatic and manual transmissions. Though the company had previously said it would only come with a true manual transmission, Chevrolet says that high customer demand means the ZL1 is also being offered with an optional six-speed automatic.

Chevrolet Camaro spokesman David Caldwell told us that the company had been considering offering the ZL1 with an automatic transmission for some time, and once customer feedback indicated there was a strong interest in such an option, the company made the decision to develop the transmission. Caldwell said “the majority” of Camaros are sold with automatics.
The ZL1’s automatic will be a six-speed unit with manual shift controls. It’s a unique transmission that is designed for the high power and torque loads of the ZL1’s engine, but Caldwell told us the design is a “sister” to the automatics employed by the Chevrolet Corvette and Cadillac CTS-V.
We also learned that the Camaro ZL1 will score Performance Traction Management, which debuted on the Corvette ZR1 and can now be optioned on the Corvette Z06. PTM is an extension of traction control that modulates engine torque to maintain maximum grip and acceleration when cornering.
The 2012 Camaro ZL1 bowed at the Chicago auto show earlier this year, with a supercharged 6.2-liter LSA V-8 engine under the hood, and output ratings of 550 hp and 550 lb-ft of torque. Those could change before the car reaches production, though, as Chevrolet previously said it was still fine-tuning the engine’s performance. The current Camaro SS boats 426 hp and 420 lb-ft from a normally aspirated 6.2-liter V-8.
To keep the ZL1 on the road and out of ditches, it rides on lightweight 20-inch wheels, has upgraded brakes (14.6-inch discs front, 14.4-inch discs rear), and Magnetic Ride Control suspension. The ZL1 wears a chiseled new look thanks to a new front fascia and rear diffuser, and trims weight with a hood made from aluminum and carbon fiber.
Expect the gutsy Camaro ZL1 to go on sale around February 2012.

I'm hoping it will be in the 12.0 range or maybe into the high 11s.......that will put a bad taste in Shelby owners mouths...lol

If its at all like the CTS-V, it should be quicker than the manuals

I think this will be helpful as a reference.

Based on the numbers in this vid, how much power and weight would the Z need to gain/lose to get into the sub 3 sec 0 to 60 and sub 12 sec 1/4 mile?

Assuming you meant sub 4 sec 0-60, I'd say that a 4100 lb ZL1 with 560 hp should manage to pull both of those off.

One would assume so as it's already available on the 2SS.
