Last time we talked about the SSC Tuatara was when the automaker claimed the car had reached well over 300 mph in top speed testing. The problem with that was there was a discrepancy in the data and video that resulted in the claim being withdrawn. SSC has now taken the Tuatara back out for top speed testing, and the speed has been certified by Racelogic.
The top speed run happened on January 17, 2021, at the Johnny Bohmer Proving Grounds at Kennedy Space Center in Florida. Data was collected by a Racelogic VBOX 3i 100Hz GNSS system that is accurate to within 0.06 mph. The equipment is also traceable to ISO standards for speed measurement.
On run one going northbound, the Tuatara reached 279.7 mph. The top speed for the southbound run reached 286.1 mph. Averaging the two runs together gives a two-way average of 282.9 mph. SSC says that data and video are available publicly.
The Importance of Accurate Speed Measurement
Accurate speed measurement is crucial in the world of high-performance vehicles, especially when attempting to set world records. The Racelogic VBOX 3i 100Hz GNSS system used in the SSC Tuatara’s top speed run is one of the most advanced systems available. It provides highly precise data, which is essential for verifying such extraordinary claims. The system’s accuracy to within 0.06 mph ensures that any recorded speeds are reliable and can be confidently presented to the public and regulatory bodies.
The use of ISO standards for speed measurement further adds to the credibility of the data. ISO standards are internationally recognized and ensure that the measurements are consistent and repeatable. This level of precision and standardization is what allows automakers like SSC to make bold claims about their vehicles’ capabilities and have those claims stand up to scrutiny.
The Journey to 300 mph
The journey to achieving a top speed of 300 mph is not just about raw power; it involves a combination of advanced engineering, aerodynamics, and meticulous testing. The SSC Tuatara is powered by a 5.9-liter twin-turbocharged V8 engine that produces an astonishing 1,750 horsepower when running on E85 fuel. This immense power is harnessed through a lightweight carbon fiber body and a highly aerodynamic design, which minimizes drag and maximizes stability at high speeds.
However, achieving such high speeds also requires a suitable testing environment. The Johnny Bohmer Proving Grounds at Kennedy Space Center in Florida provides a perfect setting with its long, flat, and straight runway. This allows the vehicle to reach its top speed safely and provides ample space for deceleration.
The previous attempt by SSC to break the 300 mph barrier was marred by discrepancies in the data and video, leading to the withdrawal of their claim. This time, SSC took extra precautions to ensure the accuracy and transparency of their results. The involvement of Racelogic and the use of their highly accurate measurement system played a crucial role in validating the new top speed run.
The Tuatara’s achievement of a two-way average speed of 282.9 mph is a testament to the vehicle’s engineering excellence and the rigorous testing protocols followed by SSC. While it falls short of the elusive 300 mph mark, it still places the Tuatara among the fastest production cars in the world.
The SSC Tuatara’s recent top speed run, certified by Racelogic, marks a significant milestone in the quest for automotive speed records. The use of advanced measurement systems and adherence to ISO standards ensures the credibility of the results. As technology and engineering continue to advance, it may only be a matter of time before the 300 mph barrier is finally broken. Until then, the Tuatara’s impressive performance remains a remarkable achievement in the world of high-performance automobiles.
