  The history of the Triumph Herald engine that is used to power the Amphicar.

The Herald engine started as 948cc in 1958. It was uprated to 1147cc (1200) in 1961 at which time is was considered the best small engine in the world for power/weight ratio and ability to run cool. This is why it was chosen for the Amphicar. In 1964 a more powerful version was developed called the 12/50. In 1968 the 1300cc version called the 13/60 became available followed by the 1500cc in 1971. The Spitfire used the same engine, normally with twin carburettors and higher compression. Up to 10:1 instead of the normal 8:1 or 8.5:1  Spitfire engines can be used in Amphicar but do not run as well at low speed, because of their more "racey" camshaft.

Visit all areas in one month
Do the 10CR
Do the HCR
Drive to the Arctic
Tunnel Runs
