1922 Daytona Beach Sig Haugdahl USA Wisconsin Special
6-cylinder in-line
IC 180+   This basically is to state vehicle did exist with potential of going way faster during this time period. He made runs according to his statement of 180 mph, the press said 170 mph. None had ever been confirmed. Why is his name in here, like they said vehicle was built, did race, and was capable of being the fastest vehicle in the world at that time.

The Wisconsin Special was driven by Sig Haugdahl to over 180 mph on a one-way run at the Daytona Beach racing oval. This was a tremendous accomplishment as the car had reached speeds a full 24 mph father than the previous record holder.

Haugdahl had built the car to prove to the USAC that he was a great race car driver and that he could outpace anyone. The heart of the Special was an enormous 836 cubic-inch Wisconsin Special Airplane engine connected directly to the rear axle. The width of the car measuring a mere 20 inches was basically the width of the engine.

To keep the car aerodynamic and stable at speeds, all exposed parts were taped, covered, and smoothed. The engine was mounted in the front with the driver, Haugdahl, sitting directly behind in it and just in front of the rear wheels. The boat-tailed rear end was designed to also reduce drag and increase the vehicles aerodynamics.
The design of the Wisconsin Special is eye-catching, the teardrop front grill, shark-gill heat vents on the underside of the bodywork, Spitfire style exhaust outlets and tiny little windshield are all quite unique as is the fact that Sig set a 180mph top speed on what appear to be wheels off a horse-drawn cart. They just don’t make ‘em like they used to.

Haugdahl determination and attention to detail paid off, and became the first person to travel three miles in a minute. The record breaking run was never officially observed by the USAC governing body, as none of its members were present during the event.
The unofficial record would stand for more than a decade.
