No more V12 SL's this generation - M275 twin turbo V12 discontinued in SL, nearing the end of its line?
M275 V12 twin turbo production for the Mercedes SL has ended. That makes us very, very sad pandas. The SL600 is the first to go followed by the SL65 AMG. The Black Series will likely be sold for a little while longer but at its price point they are not exactly flying off lots. Will the V12 re-appear in the next generation SL? We do not know, but with the M157 and M278 twin turbo V8's the demand for a twin turbo V12 will not likely be there. These are newer motors with better emissions that are also lighter. We will have to wait and see but this may be the beginning of the end for the M275.
