Randy Pobst Unleashed at an HPDE in a Modded GT4 RS - the Art of Coordinated Chaos
Randy Pobst

Randy Franklin Pobst, known as "RFP" or "The Rocket," is an American professional racing driver and automotive journalist with more than 90 professional wins across multiple racing series. As Motor Trend magazine's primary test driver, Pobst has become America's answer to Europe's test driver legends, setting track records and providing authoritative performance evaluations for over two decades. With 114 recorded laps across 94 vehicles on LapMeta, his data represents a comprehensive survey of modern performance car capabilities.

Pobst's racing pedigree is exceptional: he won the SCCA World Challenge GT championship in 2003, 2007, 2008, and 2010, captured the 1996 North American Touring Car Championship, and was vice-champion in SCCA World Challenge TC for 2005, 2006, and 2007. He is also a two-time class winner of the 24 Hours of Daytona (2001 and 2006). This extensive racing background provides him with the skill set necessary to extract maximum performance from any vehicle he tests.

His Motor Trend work focuses heavily on Virginia International Raceway, where he has recorded 62 laps on the Pre-2023 configuration and 27 on Big Willow. Pobst holds the production car lap record at VIR's Grand Course, set in the 2019 McLaren Senna—a time that no one, in any street or race car, has beaten. His notable achievements include lapping Laguna Seca in the 2016 Dodge Viper ACR in 1:28.65, faster than the Porsche 918 Spyder hybrid supercar, and breaking Road Atlanta's track record in the 2019 Corvette ZR1.

Beyond raw lap times, Pobst hosts "The Racing Line" on the MotorTrend YouTube channel, where he educates enthusiasts on racing fundamentals. His ability to communicate complex driving concepts in accessible terms, combined with his empirical lap time data, makes him invaluable to both manufacturers seeking validation and consumers making purchasing decisions. Randy Pobst represents the intersection of elite racing skill and journalistic integrity.

In this follow-up video at Circuit of the Americas (COTA), we welcome back Randy Pobst to drive my GT4 RS, now modified with Dundon parts based on his initial feedback.

Did these changes address his concerns—and did they make him faster on track, as they did for me? It’s time to find out!

We didn’t just hand him the car and walk away. We worked closely with Randy to dial in the setup to his liking: adjusting compression and rebound, repositioning sway bars, adjusting aero, and tweaking ride height to get the most out of the car.

By the end, the car felt even more compliant, but was it enough for a record lap? Watch and find out.
