IE 20V Powered VW Passat, 220 MPH and Climbing!
Integrated Engineering (IE) and Potter Brothers Racing teamed up in 2012 to build the fastest Volkswagen in the world. The goal was to set a land speed record surpassing 230 MPH. While we are still working towards this goal, we have learned an enormous amount of invaluable information that IE has been able to apply to its products that several thousand enthusiasts use today. Weather permitting, we will be back out on the Bonneville Salt Flats for another attempt this summer, 2015. Below you will find a general overview of all the work and components that have gone into this project.
In 2013 the car reached a staggering 220MPH. Be sure to check back in the future as we continue to push towards beating the current record of 227MPH (set by Seat/Skoda).
The car: The 2000 Volkswagen Passat 1.8T was chosen by Potter Brother Racing as the best possible VW chassis, due to the fact that the B5 Passat Sedan has the lowest combined drag coefficient (.27 in stock form) and frontal area (2.1 m2) of virtually any production automobile.
