The S 65 AMG leaves you in no doubt about the effortless superiority of the
12-cylinder engine, kilometre after kilometre: the powerful, effortless acceleration
in the highest engine speed range is another strength of the AMG 12-cylinder unit
along with its relaxed cruising at low engine speeds. Just as impressive as the
phenomenal flexibility is the smooth and refined running characteristics which
guarantee the high level of touring comfort traditionally associated with Mercedes.
Like its stablemate the S 63 AMG, fuel consumption and CO
2
emissions on the new
S 65 AMG have been reduced thanks to optimisation of the engine and transmission
setup as well as improvements to the aerodynamics and rolling resistance – all
despite no changes having been made to the engine data and performance values.
The NEDC consumption of the S 65 AMG is now 14.5 litres per 100 kilometres
(CO
2
: 346 g/km), an equivalent reduction of 0.3 l/100 km.
Know-how from the world of motorsport also with the AMG biturbo
V12 engine
The AMG 6.0-litre biturbo V12 engine also leverages the vast know-how amassed
by Mercedes-AMG from the world of motorsport. The V12 engine has a precision-
balanced crankshaft made out of high-strength materials, forged pistons made out
of special material which is extremely resistant to temperature and pressure, a
more effective oil-spray cooling system with a separate individual nozzle for each
piston plus larger piston pins. The main and big-end bearings are also made out of
improved materials to compensate for temperature and pressure peaks more
effectively.
The charge cycle in the cylinder heads benefits from optimised combustion
chambers and longer opening times of the intake camshafts. A modified oil pump
ensures that all lubrication points are supplied with oil - even in highly demand-
ing conditions. An engine oil cooler is integrated into the AMG front apron, with
an additional engine coolant radiator located in the wheel arch.
