Vipers are stupid...they just tried to put gobs and gobs of power by using a modified HD truck engine and puttin it into a car. Didn't work. Beats the Vette, sure, but I know of a "family sedan" that can beat the RT10's (0 - 60 in 4.
. The GTS and GTS R are faster than that @ 4.3, but they are trying to get around engineering. That is why a V8 (that's is less than half of the size of that 8L engine in the Viper) is placed in a well-engineered car, the Lotus Esprit (pronounced eh - spree, not e spirit), and kicks the crap out of any of the Vipers at the price of the RT10!!! And it is a whole lot more exotic too!!!
