“The dressmaker in the other people do, “says Murray in the podcast Previous the Grid '.

He counts himself for the second stroke: “The revolutionaries, like Chapman or me, have thought differently: 'Me do not like, the others became. Let America reroll the rules and see where we can give Americans an unfair advantage. “

The Briton always wondered, “How can we make the car a lot better, not just a little better? “With this motto, he also went into the season 1978. “This story begins with a necessity, because Lotus has discovered with the so-called 'wing cars'. “

Murray battle demanded he wanted to implement the ground effect as well. However, the battle of the Alfa-V in the tail too wide and big dime nsioniert. He still used the ground effect with side aprons to increase the downforce and speed in the corners.

“I saw us Therefore, he studied the regulations again exactly. “I found a loophole – and it became the 'fan vehicle'.”

The BT “It just had a vacuum cleaner, so it had peripheral aprons and a (******************************************************************) Inch fan in the rear, which sucked the car to the ground. ” After the model of the US sports car Chaparral 2J, he actually installed a fan in the rear.
