Brabham BT46C
The fan was declared to be for cooling, which was true for about 30 per cent of what it did. Lauda won the 1978 Swedish Grand Prix by half a minute and the car was never raced again: Ecclestone owned Brabham and was building his position in FOCA, and the other team principals made withdrawing it the price. It remains the only car to win every Grand Prix it entered.

One of the design family that has a specified page of its own.
Why it mattered
The idea. If a flat-12 is too wide for ground-effect tunnels, make the downforce a different way: extract the air from under the car with a fan
New on this car. Surface heat exchangers in place of radiators on the original BT46 (which did not work); on the BT46B, an engine-driven fan drawing air from a skirted underbody
What it did. The BT46B won the one race it started. The conventional BT46 won at Monza the same year.

A blank is a figure nobody published for this car. Where several teams quote the same number in a season it is usually the rule they were all built to rather than a measurement, so it is kept with the regulation limits instead of here.
Every entry 0 entries
No race entry in this database resolves here. That is usually a constructor that ran several designs in a season and no source saying which raced when, not a car that never raced.
