VIDEO: How good does the new SRT Viper sound? This Good.

So how good does the music from the 8.4-liter, all-aluminum, overhead-valve V-10 engine from the new SRT Viper sound? Well a few seconds of this clip brought to us by Road & Track can answer that for you. You’ll be reaching for words like bad-arse, menacing, throaty, mother of gawd, and so on, and so on. With 640 ponies mated to a 6-speed manual transmission, the venomous snake is so back, and badder then ever. We can’t help but want Christmas to come a little earlier this year.
