About the Williams FW07

Patrick Head, Frank Dernie and Neil Oatley based the FW07 closely on the Lotus 79, developing it in the same Imperial College wind tunnel but with a stiffer chassis, and powered it with the Cosworth DFV. After Dernie improved the skirts and sealed aerodynamic leaks, Alan Jones took pole at the 1979 British Grand Prix and Clay Regazzoni won the race for Williams' first victory, with Jones winning four of the next five rounds. In FW07B form, so effective that front wings were unnecessary, it carried Jones to the 1980 title and Williams to the Constructors' Championship, helped from mid-season by John Judd-developed DFVs giving 500 to 510 bhp. The FW07C added a second Constructors' title in 1981, and the family won 15 Grands Prix before the FW08 replaced it early in 1982.

Williams FW07 rarity in CarSpot

The Williams FW07 is a Unicorn card in CarSpot, with a rarity score of 100 out of 100. The rarest tier: hypercars, one-offs and cars built in tiny numbers, typically fewer than about 500. A Unicorn card is worth 320 XP.

Each model's tier starts from a 0–100 score based on its value plus its power or production numbers. Once enough players have spotted a model, how often it is spotted can move it up or down one tier. How CarSpot rarity works

Rarity is a collectible game mechanic, not an assessment of real-world scarcity or value.
