STRAIGHT TALK –
RICARDO DIVILA
Taking the nuts to Brazil
Recalling a time when getting to an event was as much an adventure as the race itself
F
orty-six years ago there was an expedition
to the darkest parts of the South American
continent by a band of intrepid Brits, doing
all the things people did in the comics such as
The Eagle.
It wasn’t meant to be that way, but the
combination of the idea of sending a gaggle of Brit
Formula Ford racers on a ‘Temporada’ in Brazil with
a sprinkling of South American drivers for local
interest, sponsored by Ford of Brazil and British
United Airways, coupled with the sheer size of the
sub-continent, made for some interesting moments.
Emerson Fittipaldi had won the
Formula Ford Championship by May 1969,
in his first year in the UK, and both UK F3
championships by the end of it. TV company
Rede Globo and Ford thought it would be a
good idea to contact John Webb, then owner
of Brands Hatch and a Formula Ford race
organiser, to corral a suitable representative
group of Formula Ford stalwarts and
capitalise on this. British winter being what
it is, it was not too difficult to find a group of
racers and mechanics happy to escape from
the snow, while the good prize money on
offer might have helped a little, too.

I – a local brought up in this sort of climate – was
struggling a bit, as I had spent the European winter
in the UK, losing my acclimatisation. But the sizzling
weather did not deter the crowds, and there was a
sizeable audience of 35,000 spectators for the start
of the event – not bad for a Formula Ford race.
