This is also true. With a flat road, and lots of distance.....maybe 180s-190s could be reached in 6th? (No idea)

The manual ran 180, the auto ran 184

If you read his post again, you'll see that he was answering a question about the 5th gen.

6th gen is still a mystery. M6 video that was posted, they let off the throttle. A10 is not even out yet.

I assumed that at least the manual couldn't do 200 mph because of the 3.73 gearing. The viper and zr1 have 3.31 gears in them. The 2013-2014 gt500's were switched from 3.73 in the 2011-2012 to 3.31 as well to get the claimed 200+ mph.

that spoiler looks good for downforce , bad for top speeds, I know tannot that extreme but look at the top speed difference between the acr viper and the non acr model.

With this change, 5th gear would be capable of 196, mathematically. 1st would also be capable of 70mph....can you imagine rolling away from a light with that!?

The transmission ratios and rear end need to be part of a cohesive system. Changing one by itself may not work.

[Stoner]

The Viper and ZR1 both have a significant aero dyanamic advantage over the ZL1. I can't remember the ratio between horse power, weight, and coefficient of friction, but it take lots of horse power to over come weight and aro dynamics.

When you look at the video of the auto on the "ring", even then it looks like it's struggling to get over 180. It appears that top end performance wasn't on Chevy's radar, even with 10 gears to work with. I hope all those ratios helps in knocking down some impressive 1/4 mile times. If GM truly got 127 mph out of their a10, this car should run very low 11s on street tires.

We already know it's going to shine on the road course.

...Keep in mind that 3/4 of that entire straight is up hill...

Found this:

At a few thousand dollars less than the 707-horsepower Dodge Charger Hellcat, the ZL1 is likely the cheapest new car with a top speed beyond 200 mph. Chevrolet isn't saying anything about the maximum velocity (at least not yet), but come on. This much power? With a lot less frontal area than the broad-beamed Charger? Two bills at the top end is inevitable.

Cant wait to see one run on the salt, or at one of the other top speed events!

Strange...it looks like it's mostly downhill from the video.

From timestamp 6:48 to 7:08 it's an uphill run...and the grade in the second half of that segment is quite steep. Then, immediately after the bridge, it goes downhill slightly, and the car climbs from 177 to 181 in a couple of seconds. But there's only a short distance before he needs room to brake for the next corners.

I look at the C6 ZR1, which reached 183mph @ 6550 rpms on that same straight...so 181 @ 5300 rpms out of the much more blunt instrument that is the ZL1....not bad!

I would very much like to see what the automatic version can do on a flat straight, or one of those huge oval top-speed tracks like Volkswagen has.

I still don't think top speed is very important, though.
