What exactly is a DSM?

Technically, a DSM is a car built by Diamond Star Motors, a joint venture between Mitsubishi and Chrysler. More details about DSM are here.

For the purposes of the Talon Digest, the definition of a DSM has been extended somewhat; 

[Note: From time to time, debates on the definition of a 'DSM' emerge on the Digest. These debates usually center around a record-breaking car which, because it does or does not have a certain component or feature, 'should' or 'should not' be considered a 'DSM' in the 'true' sense of the word.

Such judgements are entirely subjective and cannot be resolved, except by arbitrary rules; resist the temptation to reopen any such debate as moderators and membership are tired of hearing about it. All race results that can reasonably be deemedrelated to DSMs are reported - whoever is king in your own mind is best kept to yourself.]

In further news, the now-merged DaimlerChrysler corporation purchased a 34% stake in the now-ailing Mitsubishi Motors corporation in April, 2000. This is not to be taken as a re-emergence of DSM, however - the DSM marque is now consigned to the pages of history.
