Just a random Monday thought after a weekend of Le Mans viewing.

Many years ago the WM Peugeot team succeeded in their goal of sending their car down the Mulsanne at 400 kph. They only managed it by going for the lowest downforce spec with narrow tyres and all the radiator/cooling ducts taped over.

So radiators are a bit of a nuisance, stick out into the airstream, increase drag and upset the aero package. Many years ago before WM at Le Mans Gordon Murray designed the F1 Brabham BT46 with surface cooling, no rads, just a car covered in what looked like solar panels - although working in reverse.

It was a failure - the cooling was ineffective. Could it work in the 21st century - or do FIA regs disallow it ??

Only according to the Internal/men in pubs. According to the team themselves the car was designed to be low downforce and all they did for the high speed runs was to turn up the boost - http://www.dailysportscar.com/2018/06/15/le-mans-h...

The underwing radiators on the Supermarine Spitfire actually produced a small amount of thrust rather than drag.

Only at high speeds. At F1 speeds they'd be draggy.

Radiator cooling matrices have a lot of surface area which would be greater than that of the car body. So unlikely it would work.

The Meriedith effect from the radiators PLUS the thrust from the engine exhausts made the engine/cooling system almost drag neutral in certain variants.
