b
In September 2012 Mercedes-AMG will introduce
the new 12-cylinder V-engine M 279 AMG in the
new SL-Class
(model series 231).
This advanced V12 engine with the model designa-
tion M 279 focuses rigorously on performance and
fuel efficiency in equal measure. It replaces the
su
ccessful unit of engine model M 275
.
Numerous combustion-related and applicational
optimizations have significantly reduced fuel
consumption and emissions while simu
ltaneously
increasing engine performance. Also helping to
improve emission levels and fuel economy is the

second-generation "Controlled Efficiency" start/
stop function including alternator management,
which has been modified to cope with the high
torque of the M 279 AMG.
