IE Powered VW Passat, 220 MPH and Climbing!
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.
Chassis features: -Stripped to bare shell for race preparation. -Double-hoop rollcage built to SCTA specs for 'over 200 mph'. Rollcage constructed of 180 feet of 1.625" DOM thickwall tubing, by local Salt Lake City expert fabricator, Brian Thomas -DJ Safety parachute system with expertly engineered ‘neutral’ tether point, fabricated by Brian Thomas -Roll cage and interior bodywork painted in OEM Satin Silver -Four doors gutted, with lightweight trim panels and dashboard top padding installed as per SCTA Production Category rules -All windows except windshield constructed of Lexan by Potter Bros Racing -Fully adjustable 4-link front suspension, with custom dampers, spring rates, and alignment settings by Potter Bros Racing, OEM brake components -Custom zero-offset 15x4.5 rear wheels with Goodyear Eagle 26” diameterracing tires -Fully blueprinted and seam-welded OEM VW steel front wheels with 23" to 26" diameter tire choices for gearing flexibility. Moon Discs with Dzus fasteners for Aero and Cool factor -Entire OEM electrical system discarded, one-off electrical system designed and installed by Integrated Engineering -All exterior lights, equipment and trim in place as per SCTA production rules, with only allowance being removal of exterior mirrors -IE designed and constructed driver-actuated dual independent aerospace-spec foam fire suppression system with multiple cockpit and engine bay nozzles -Drag Coefficient with allowable modifications:(cD) .26 -Completed vehicle dry weight: 2950 lb.
