V8 - What for? To have a lower priced version?
Jeep is currently diluting their brand from capable, tough trucks to mall assault vehicles just like GM did with the Hummer H2 and H3. Will they dilute the Viper with a V8 version? Maybe. Then a V6 followed by an inline 4 (that makes class leading power!!! woohoo). This will boost sales and increase profits, but it will become meaningless to own a Viper.
It happened to me with the Hummer brand. I can't tell you how many times I've been asked "You have a Hummer? One of the new ones?" I reply "No, I own a REAL one."
If Dodge makes a Viper with less than a V-10 when you tell someone that you have a Viper they'll assume you have the less expensive, high volume version, just like their Aunt Maggie has.
Personally I don't care what others think but I don't want to be cubby holed with something I don't like. I'm the type of person that has a V-10 Viper - not the V8 kinda guy. And really, if I wanted a Vette, I would've bought a Vette.
