----------------------...The
Lotus Seven began as an uprated
----------------------version
of the successful Lotus Mark 6.
----------------------Its
introduction was put off until time was
----------------------found
in the busy racing schedule.
---------------------...The
chassis is a simplified version of the
----------------------Eleven.
----------------------...It
has a steel tube frame with stressed
----------------------aluminum
panels in the undertray and sides,
---------------------
and aluminum bodywork, ( later with glass-
----------------------fiber
nose and fenders ).
----------------------...A
variety of engines ( BMC, Ford, and
----------------------Coventry
Climax ) were used, and many
----------------------upgrades
were made over the 16 years of
----------------------production.
----------------------...Low
and light, with incredible handling, it
----------------------is
very quick, and a winner of innumerable
----------------------club
races.
----------------------...Lotus
discontinued production after the
----------------------introduction
of the steel backbone framed,
----------------------glass-fiber
bodied, Series 4 ( Type 60 ).
----------------------...Licensed
replicas are still in production
----------------------today
as a variant of the Series 3 Seven,
----------------------called
the Caterham Seven.-----
