RE: Which viper
The SRT-10s, both the Coupe and Convertible have them, I'm not sure off the top of my head about the GTS or RT/10.
Romesky gave a good reason why the Viper can't (stock) hit 200Mph:
Don't be suprised if the 2008 Viper hits it though

Ok.
I have questioned the vipers top speed for a while. I did some research yesterday and found some very interesting things. First Dodge and everone who test the viper says it's top speed is about 190. People on the forums talk about it making trips to 199 ungoverned. I have only found facts pointing towards the viper having a rev limiter but not governed. So I look a little deeper in this whole mess. First I used a control car. The new ZO6. I picked that car because it has be test but everybody and their brother. It top out at 198. It has about 505 hp with a drag coefficient of .34(now keep this in mind .34cd). Understanding that at 190 mph a car needs 5 hp to go 1mph faster; a picture starts to be painted. If the ZO6 wants to hit 200mph it needs about 515 hp. Ok very good example. Now the viper. IT is said that it could do 199, well that would seem to add up at first. ZO6 does 198, the viper has about 510 hp, 1mph =5hp. IT seems like that could happen, but wait Oh, do you remember that drag thing I was talking about. Well the vipers CD is .39, and with some math tricks I came to a top speed sum of 189 for the viper. That is 1mph slower than anything I have seen before so I thought my math was a little shady. Until I found a website by a guy that said his viper would do 189 and some change. It all started to make sense. 189.758946887 is rounded to 190 and everyone is happy to print that. SO what I'm saying is that the viper is drag limited to 190. Yeah you could get a stock one to do 199 but you would have to push out the back of a cargo plane.
formulas I used; Cd=D/rA*v^2/2
Aerodynamic drag= 1/2D*A*v^2

RE: Which viper
Let's not forget the z06 went through an intense weight reduction program. A stock srt10 is already geared for 314mph, thats why the vipers gears are messed up, and perhaps a factor related to the vipers top speed.

RE: Which viper
No, the production of the 2007 Viper is being halted. Dodge plans to revamp the design and all so it's comparible to the level of a Saleen S7. From sources, it will no longer have competition with the Vette, or the GT and will finally be America's Supercar... under 100k obviously.
