The Controversy of the 331mph SSC Tuatara World Record - Case Closed?
The SSC Tuatara's 331mph world record top speed run has certainly been a controversial discussion! Following my questions surrounding the published video, Jerod Shelby has now announced that SSC will be doing another run with the Tuatara to set the record straight. However, there are still concerns that haven't been addressed that will play a part in the next attempt.
SSC reported that on 10th October, 2020, the Tuatara in production specification form broke a top speed record with one direction at 331.15mph and the other at 301.07mph for an average of 316.1mph - beating the previous record of the Koenigsegg Agera RS by 38.2mph (from 277.9mph). The runs took place on the very same road, the Nevada Highway 160 from the intersection with Tecopa Road with the Tuatara's fastest direction heading South-East towards Las Vegas and the slow speed on the return.
After the initial questions I raised surrounding the video published by Top Gear, a number of statements, press releases and bits of information have surfaced which introduce further questions to discuss. Equally, the topic has generated all sorts of stories published and discussed at length, some of which have perhaps been incorrect.
With further analysis of the initial record run itself, join me to further establish the particular video footage used, the gearbox within the car through sonic visualisation, and the speed traveled relative to an Airbus H125 helicopter flying alongside.
A huge shout out goes to Kaare for his work starting on the analysis of the audio, and the guidance to continue doing so in a bid to understand the gearbox ratios further.
