The terms "performance" and "diesel" used to be mutually exclusive, but times, they are a-changin'. Audi's dominance of LeMans with its R10 TDI and the recent unveiling of the R8 V12 TDI
concept might be giving Mercedes a reason to turn towards oilburners for some of its high-po offerings. AMG has made a name for itself by providing, among other things, torque-rich engines that sometimes have to be electronically limited due to their tire (and differential) decimating potential. AutoExpress
supposedly has it on good authority that plans are in the works to offer diesel models with an AMG badge, but both Mercedes and AE
failed to provide any details about what vehicles or engines would be used. It might be a forgone conclusion that new CAFE standards in the U.S. are causing automakers to rethink their performance offerings, but in the meantime, we're going to throw this in the rumormill and see what comes out the other end.
