Developed under the leadership of Chief Engineer – Engine Design and Development Willem Weertman and head of performance tuning Charles "Pete" Hagenbuch, who had worked on most of Chrysler's V-8 engines and the Chrysler Slant-6 engine, [1] it was introduced in the 1981 Dodge Aries, Dodge Omni, Plymouth ...
V-8 engines were produced by the Daimler Company in displacements of 2.5 L (153 cu in) (1959-1968) and 4.5 L (275 cu in) (1959-1968). Designed for Daimler by Edward Turner, they were initially used in the SP250 sports car and the Majestic Major saloon respectively; ultimately, the 2.5 L was mostly used in the Daimler 2.5 V8 (later named V8-250) saloon made with Jaguar Mark 2 unit bodies from ...
