Brought to you by Aramco: https://bit.ly/3xCbsb1 The Brabham BT46B – better known as the fan car – only raced once in Formula 1. But it made a profound impact and is celebrated to this day as a beacon of technical ingenuity. Most F1 fans know the basic story of Gordon Murray’s car, which won the 1978 Swedish Grand Prix in the hands of Niki Lauda on its sole racing appearance. As an answer to the ground-effect innovation of Team Lotus, a large fan attached to the rear of the Brabham created a similar effect by sucking air out from below the car, pulling it closer to the ground and sealing the underfloor with the side skirts. But there’s a lot more to the story than that, as well as some legends about it that aren’t quite accurate. So we’ve dug into the detail of one of F1’s most legendary cars to bring you some facts you may not have known. And to make it easier to understand this famous car, we’re very grateful to @f1passionit for sharing their tremendous 3D model of the Brabham BT46B
