The
BMW M3 GTR was powered by a V8 as opposed to the straight 6
which powered the regular BMW M3. Only 10 street legal M3 GTR's
were produced for homologation
purposes to enter the American Le Mans Series (ALMS). The asking
price for one of the 10 street legal BMW M3 GTR's was a stratospheric
$218,000 ( £120,000).
However homologation rules were later rewritten, requiring 100
street cars and 1000 engines to be produced. Because of this
BMW decided to withdraw the M3 GTR from the ALMS, and therefore
axed the M3 GTR altogether.
