Z/28 Auto? I sure hope its an option cuz its quicker in the CTS-V

[BigDan]

I sure hope they offer the A6 as an option in the new z/28. Purely for performance reasons. The auto is quicker to 60mph and quicker in the 1/4 mile over the manual in the CTS-V and keep's getting better then the M6 once you start modding it. You definetly want a auto when you are drag racing a supercharged car since you dont loose any boost between shifts. There's an auto CTS-V with exhaust stock tune and DR running 12.2 and 11.2 (598whp) with pulley's and exhaust. Imagine a LSA with 2.9L Whipple with a cam exhaust , yank 3600, and 3.90 gear's should be good for 770whp easy and would get me off the fence pretty quick

I'm on the fence right now between the 2011 AL block GT500 vs the 2012 Z/28 if it has an auto.

I'd like the auto because it would be alot more controlable and safer at 750+whp range

BUT do you realize what the Z28 use to be (and the way it will probably lean this time)? the Z was not the drag strip car. SS 396's and ZL1's were. the Z28 was a road course car. for that you want that manual.

Paddle shifters..........
Seriously, though --
Outside of dragging the car, I think offering an Automatic makes a lot of sense...because the GT500 does not.

They might suprise us with the new six speed auto they are going to be offering.

I know they pulled a join-venture with GM to develop the transverse 6-speeds both companies use. I haven't heard of a RWD unit....

far from stuck in the past. looking to the future DI v8 with 6 speed manual TR-6060 (aka t-56 magnum). learning from it and making it better.

[TAG UR IT]

GM would have to be NUTS NOT to offer the Z28 with an auto.

There's a LOT of folks who want the go fast without all the work of shifting. There's the older crowd who either can't or don't want to use that left leg anymore for all that shifting. Then, there's the people who get tired of it in all the traffic..stop...go...stop...go...

The competition does NOT offer their top tier cars in auto (to my knowledge) and this is one area that GM could REALLY hit the nail on the head if they went with an auto.

GM....DO IT.

Get over it, its just a name, and if GM were to make a modern day z/28 they use a supercharged DI V6.

How much boost can a LSA take?

It comes from the factory with 9 pounds.

The Hennessey guys have upped the power to 700 hp with success...no idea on what boost they're running, but they did do a pulley swap, and did not mess with the insides other than a cam and heads.

is that the LSA or LS9?

LSA...alllll LSA.

[brick777]

I agree, a 6 speed auto like the one on the CTS-V should be offered for all the reasons stated in favor of it...it has greater performance potential on the strip and track ( just ask any cts-V owner who owns the auto...they swear by how great it performs) and because some people just don't want to shift, and because perhaps some people who desire to have a Z-28 just can't use the clutch for disability reasons. Let's not get arrogant and forget those people who desire to drive a great sports car. Options for all is a good thing!

wow. did I tell you to get over it? no, sorry just like some people on this forum this is more then a name and a car. some people are passionate about other things you sir must be.

the car you want is the ZL1. and hopefully they make it. the Z28 is not a V6 and would be completely stupid on the basis of the arguments I've seen on this forum. weight savings? not as much as you might think. not enough to count.

as for the LSA that will more then likely be in the Z28 and I have not argued the point it shouldn't be in the car with an auto. my argument is if you want a drag car the z28 shouldn't be your first choice. if you go with what the Z28 and ZL1 were. I'm also not saying it won't slaughter the 1320. just saying it's over all purpose is completely different then what you want to use it for.

why do you not want your car to turn? seriously some of us drive on curvy roads. and the 1320 just doesn't last long enough to matter. it's like a ton of build up for a ride at Disney world. 3 hr wait for a 30 second ride. but to each his own.

Yes - please keep things civil

I wanna' see some times from someone who knows how to drive a stick, drive a CTS-V with an M6. I, too, haven't read a review where the stick was faster than the auto', but I don't see a reason why that can't be the case, unless the TM in the stick is more pronounced to save the powertrain Anyhoo, with a couple rags' running almost bottom 12s, in an auto', I think there's a good chance of a good driver actually scratching the 11s with the stick.

I agree that a good 1320' car will usually be an auto' for most drivers, and for good reason. It's certainly not as fun, for the most part, but it's usually quicker down the track. I DEFINATELY agree that an auto' should be offered in Z28 too; they already have the 6L90 from the CTS-V, so why not?

I'm sure I'll go with a stick (regardless of engine in Z28) because I miss driving one. I'll admit there was nothing like my last car with a somewhat big stall and drag radials, but it wasn't fun after I past the 60' mark. The last two cars we've had have been A6s, with paddles shifters, and I just don't like them for serious playing around, let alone driving. Put a nice stall in one of these though, and I bet there's a big payoff.

M6 for me though

[RSHugger]

Lets just say after two slices and dices on the clutch actuating knee that I want the auto option. The stick would be great fun but I know how tired/sore the knee gets after a day of pushing in the clutch and I do not want to find out that after I get the big bad dog (what ever Z they want to call it) that I can not enjoy it because the Aleve wore off and the car just sits in the garage! And I am really not that old (maybe compared to Fenwick) ... too much basketball!

The CTS-V that set the record at the Nurburgring?

Auto.

I think it will do just fine

It state's that it will be in all car's by 2013.

Ohhh, I do remember that. I had written it off in cars like the 'stang due to their inability to handle high-torque applications. Porche and BMW are shying away from them...

Interesting. I could see GM buying these units if they're any good, because they aren't developing their own.

Who are they?

Honestly that could be why they are'nt using it on the Mustang's yet.

700... probably around 10-11lbs. tho with the h/c swap, 700 at the crank isnt too hard with the LSA.

LSA is ~9 stock, LS9 is ~10 stock

but who likes stock? lol

Auto's can be used for more than the 1/4.

why should it be faster than the auto? these aren't the slushboxes of yesteryear.

[ColorBlind]

I hope they offer the auto and the manual in the Z28. I love a manual, especially since I live in the mountains and run a little on a road course, but I am getting older and have a bad ankle. A lot of driving in a manual starts to hurt so I will probably get the automatic if they offer it. I know that the manual is more fun and in my experience a better road car (I have never driven a paddel on a road course) but I can still have fun with an auto and be able to walk without a limp when I get out. Its not always about being the fastest anymore, just about having the most fun.

agree. but the op wants it for Drag racing. which is fine and believe me when I say I know autos are more consistent for bracket racing. which is what counts. being fast and consistent.

I have not said once the auto shouldn't be in the car. I think it would be utterly stupid for them not to offer it. but that's just me.

in the future most "super" cars will have paddles, oh wait most due. reason an auto can shift faster then a human (for the majority of us). who knows with a better transmission setup (gearing clutch etc) the manual may be just as fast if not faster. but we won't know that because of the current setup is what GM went with. unless you can show me a CTS-v manual with a more agressive setup.

I just think because of the direct connection, there should be less power loss, and a great driver will be able to go faster than a stock auto'. I've seen it many times, in terms of trap speed and ET for LS1 cars, but like you said, I recognize the newer slushboxes are far more advanced, and I think the gear spread now is certainly better than on the 4L60s and 700R4s. That's just me. Until someone can either show me factual data the otherwise, or show be in a car, that's just the opinion I have. All bets are off though with a converter and tranny tuning though; I'm not even going to go there.

[gunslinger]

For me, there will be no transmission that offers the degree of control and fun gained from being able modulate the clutch... not to mention the thrill of a perfectly executed heel-toe down-shift, done not by a computer, but by a skill that has taken a long time for me to perfect.

Also, with a clutch you can go from daily driver smooth by letting the clutch out just above idle or you can do a hard launch by revving to 4,000 RPM and feathering the clutch...all without having to reprogram the PCM.

I want to tell the car how to behave and no automatic or even DSG will allow this. Performance and Sport buttons don't do the same.

That's just my opinion and is only valid as long as my left leg works ok.
