Do British sports cars have a 12V or 6V electrical system?

Modified on Wed, 11 Jan, 2023 at 3:49 PM

With very few exceptions, almost all British sports cars manufactured in the postwar era have 12V electrical systems, including those from Austin-Healey, Jaguar, MG and Triumph. 


Some models, such as the Austin-Healey 100, Austin-Healey 100-Six, MGA, MGB and MGC utilize twin 6V batteries that are wired together to deliver their voltage, but these are still 12V systems.
