At the recent Utah Salt Flats Racing Association’s (USFRA) World of Speed event at the Bonneville Salt Flats, a specially-modified 2019 VW Jetta recorded an impressive track speed of 210.16 mph. During the run, the Bonneville Jetta broke the Southern California Timing Association’s (SCTA) Blown Gas Coupe (G/BGC) class record.
Modifications to TSI Engine for Bonneville Jetta
For the speed record attempt, specialists at THR Manufacturing in Ventura, California made modifications to the Jetta’s 2.0-liter direct-injection and turbocharged TSI engine, with new connecting rods, pistons, valves, camshafts, turbocharger, and exhaust system. These enhancements resulted in an incredible output of 600 horsepower.
“Achieving this speed at Bonneville is a demonstration of the quality, durability, power, and efficiency of the Volkswagen TSI engine series and the stability and aerodynamic efficiency of the all-new 2019 Jetta.” – Hinrich J. Woebcken, President and CEO, Volkswagen Group of America
Additional Enhancements for Bonneville Jetta
In addition to the modifications to the TSI engine, the Bonneville Jetta had many other enhancements. The suspension was lowered, special salt flat wheels and tires were fitted, and a limited-slip differential was added to aid traction. Inside the cockpit, many of the original components were removed and replaced with a roll cage, a fire suppression system, and racing seat and harness. Also, the Bonneville Jetta had a couple of parachutes installed to help slow the car down after each run.
