Background
Designed in the late 1950s by talented British motorcycle engineer Edward Turner (Ariel Square Four, Triumph twins), the diminutive 2.5 liter Daimler V8 used aluminum alloy, hemispherical heads and closely resembled a miniature version of Chrysler’s legendary and much larger hemi.
Most famously fitted to the historically Jaguar-adjacent firm’s controversially styled, fiberglass bodied Dart SP250 sports car, the extra-small block Daimler hemi measured just 30” long and churned out a smooth 140 hp and 150 lb-ft of torque, later to be punched out to a full 4.5 liters.
According to the Jaguar Daimler Heritage Trust, Daimler’s 2.5 V8 provided smoother running and better performance than Jag’s own 2.4 liter straight-six, resulting in 1962-1969’s limited production Daimler 250, essentially a Mark 2 saloon with the little hemi in place of an XK dohc six.
