Monocoque was not an option in the late 1950s, so Triumph made a virtue from a necessity and developed a chassis which could be modifed for multiple body styles – including the Spitfire and GT6 covered separately. Perhaps intended as an interim but survived the 60s, beyond its putative FWD replacements.

Triumph Herald
Replacement for the Standard 8 and 10 (with a Standard-type name). On a chassis as Standard-Triumph struggled to source monocoques. Smallest turning circle of a production car, excellent all-round vision, independent suspension.
