Indeed...and a Class Record Holder. I don't recall any LTD wagons of such caliber, but Richard Charbenneau was a Champion with a "non-existant" 427-410 Fairlane Wagon and Lynda Pleva-Philipps' 427-410hp '67 LTD was a threat for a while in D/SA...but couldn't pull a wheel...

Is that a 1968 Roadrunner in the far lane? Is there in Hemi in there?

From AutoLine (which isn't a "line"): The automatic transmission equipped car ran the 11.93, but the manual which ran 11.96 did so without launch control.**

So, folks, the 11.93 was WITH PTM...

PTM =/= launch control. The auto cars don't have launch control.

Pretty soon we will be seeing the "broken in" cars at the track. It's going to be a lot of fun watching Camaro5 and the excitement this summer shall bring everyone!

Some of you are really showing your desperation right now

ZR1s were mentioned. 51-49 distribution (same as a ZL1!!). 3353 lb. Curb. Almost 400 fewer lb. over its 335s than the ZL1 plants its 305s with...

Ever wonder why, in the "old days", 6- and 9-passanger Wagons in Stock and Super Stock pulled such wicked 60' times? Extra weight over the rear wheels...

Here's an O/Stock-Automatic 350-255hp Impala Wagon...(NO transbrake!) pullin' daylite...

BTW, good luck with your Shelby in Sherwood...

Yeppers! I think that means a lot! It's also why the El Caminos had trouble hooking --- too light on the rear end!

I don't believe 'Launch Control' is the same as PTM. Aren't they two seperate things

Exclusive Performance Traction Management for the race course, and the drag strip
The Camaro ZL1 will also offer Performance Traction Management (PTM) as standard equipment, which is exclusive to General Motors. First introduced on the Corvette ZR1, PTM is an advanced system that integrates magnetic ride control, launch control, traction control and electronic stability control, to enhance performance on the racetrack and drag strip.

For example, the launch control feature (manual transmission only) automatically modulates engine torque for the best possible acceleration without excessive wheel spin. When the driver pushes the throttle to the floor, the system holds a predetermined engine speed until the driver releases the clutch. Then, the system modulates engine torque 100 times per second to maximize the available traction. The system is capable of approaching a skilled driver’s best effort and repeats it consistently.
Similarly, on a road course, the driver can apply full throttle when exiting a corner and PTM will automatically manage acceleration dynamics to maximize exit speed based on available traction.

Five PTM performance levels or modes are available to accommodate the given ambient and track conditions, driver experience/vehicle familiarity and driver comfort levels. They include:

• Mode 1 – Traction control set for wet conditions, with stability control on and Magnetic Ride Control set on Tour.
• Mode 2 – Traction control set for dry conditions, with stability control on and Magnetic Ride Control set on Tour.
• Mode 3 – Traction control set on Sport 1, with stability control on and Magnetic Ride Control set on Sport.
• Mode 4 – Traction control set on Sport 2, with stability control off and Magnetic Ride Control set on Sport.
• Mode 5 – Traction control set on Race, with stability control off and Magnetic Ride Control set on Track. Launch control tuned for VHT-prepped drag strips.

“Like the Magnetic Ride Control, the Performance Traction Management system improves the ZL1 experience as a daily driver and on the track,” said Oppenheiser. “By offering five distinct modes of traction management, the driver can select what’s best for them based on their experience and the driving conditions. As a result, novice drivers will find the ZL1 is very enjoyable to drive, while expert drivers will find PTM supplements their driving skill without interfering with their intentions.”?

My understanding is that Launch Control in not PTM, but is a function that is available when any of the PTM modes is selected.

/= means not equal to. PTM is not launch control.

Ok, the "7:41" may not have been disproven yet but with heatsoak issues like LPE just had going 200mph, how much heat soak was going on after five minutes of hard driving in Germany? Most people can put 2 and 2 together.

You could be right, but I have driven thousands of miles in Europe with Mustangs and Corvettes at very high speed and watched temperatures closely without ever experiencing overheating.

Another point: In one of the articles, GM and Chevy said they had run a drag strip launch over 1000 times in the ZL1 testing it's capabilities. That being said, wouldn't you think that they would have 1. chosen a very talented drag racing experienced driver? 2. with that many runs wouldn't they have experienced at least some Banzai runs that could have reached the levels they claimed? 3. If the driver weren't an experienced drag racer running the tests, wouldn't he have become one after a thousand launches? 4. After that many launches, wouldn't YOU be the world's expert on how to get the best times from a ZL1? In those scenarios, I think they could easily and honestly have quoted their best times. In all the delivered ZL1s I doubt the total would be 1000 runs even today. Patience is a virtue! We're most often finding the ZL1 surpasses most doubters expectations.

I think you missed the point. It has nothing to do with driving a mustang or vette at high speeds in Germany, or Africa for that matter. I'm assuming you've never owned or driven a PD blown car? Maybe im wrong. My old CTS would have its tongue hanging out after 3 back to back highway pulls. The intercooler fluid and blower gets hot and the engine starts pulling timing to compensate and not hurt itself. The ZL1 is not immune to this was the point. You go to any auto cross event and look at what all the big dogs are running. Usually not a PD blower.

The ZL1 runs cooler than you might think on track. Airflow was maximized in the tunnel with the ZL1 and tested extensively for road course use. The result is a FI motor that likes to run hard at speed. At the drags or an AC a ZL1 will get hotter than it would running the Ring or most any track due to lack of air flow except for short bursts.

honestly I think most people are missing the point.

drag race pretty much 100% load on the engine once you have traction. short bursts fully power only reach speed for a few seconds. basically ~12 seconds of airflow and then your down the retrun lane at real lows speed to sit. The engine will build heat wile sitting.

road corse alternating loads from 100% to 0%. you are allways at some speed so there is airflow. airflow is what cools a car.

now I tried to make that about is simple as I could. So as you can see it is plausable for a car that heats under drag race condition to sustain proper tempartures around a road coarse.

... I have been driving the car from day 1 on mode 5 as delivered. Haven't tried to power launch the car as described yet. I can say the car is freakin nutsy fast. I would like to do a 1320 with the nannies off however.
