Sorry but I don't think it can beat the GT-R, the MP4-12C, the Aventador, the F12 or the Veyron.
With all due respect, I beg to differ. In fact the Viper handed all of these cars (except F12, which has yet to be tested) their a.rse on Nurburgring and/or Laguna and a bunch of other famous tracks. It's amazing that it continues the proud legacy of the "working class" American hero that boldly spits in the face of the European aristocrat hypercars, a tradition started by the great Carroll Shelby and the Cobra and continued with the GT40 which totally dominated Le Mans for years.
Yet the Jeremy Clarkson types in Europe continue to program people's minds into thinking that American supercars can't handle corners or break. "No finesse to the suspension..." my ar.se! Funny enough the only Viper Top Gear EVER had on their track was a Gen III vert on a completely soaked track (which still put down an amazing time for such conditions). Yet Pagani was recently forced to admit to cheating with their Top Gear record-breaking Huyra (that used Zonda R slicks), while the Ferrari cosa nostra regularly sends an F1-like team of staff and two cars (one for straight line speed, one for track) on any pre-approved magazine test.
So please don't tell me record breaking laps don't count, BECAUSE THEY DO. It's part of the Viper DNA, not just some awesome side benefit. That's why the 1.33, 7.22 and 7.12 proudly decorate our ACR soldiers. That's why we had a 23-page thread (with SRT Engineers spending hours viewing it) on the original loss to the ZR1. That's why the T/A was rushed. SRT's CEO is most likely the fastest CEO on the face of this planet. The SRT engineers are probably the fastest engineers on the planet. It's a purpose-built car and that purpose is mostly to obliterate anything on a track.
To me it's the the voluptious body lines oozing aggression that is side benefit of ownership, not the fastest-ness of these cars.
So, to recap: on Laguna Seca the T/A would beat a similarly equipped ZR1 by more than 2 seconds, which in turn would beat the $300k+ Eurodream cars by another 2 seconds. Yes, it matters.
