Engine 113 - Technical highlights
SLK 55 AMG
The SLK 55 AMG affered by
Mercedes-AMG is the only vehicle in
this class available with an
8-cylinder engine. The AMG 5.5 I
naturally aspirated engine in the new
SLK develops 265 kW and 510 Nm
tagether with the AMG sports
exhaust (which is perfectly tuned for
the 8-cylinder engine).
Engine 113
The engine's technical characteris
tics are:
• Two-stage variable-length intake
manifold
• Near-engine mounted catalytic
converter for lower emissions
• Specially tuned engine oil cooler
in the right wheelhouse
• Redesigned engine cover
• • Model Year 2005 @ Model 171
• Engine control module installed
in the vehicle (in an AMG-specific
module box)
• Lower fuel consumption due to
optimized combustion, reduced
friction and consistent
lightweight construction
Engine 113 - Exhaust system
AMG exhaust system
The AMG sports exhaust system in
the SLK 55 AMG satisfies the US
emissions Iimits and is perfectly
tuned in terms of function and
sound to the AMG 5.5 I VB engine. The near-engine mounted bulkhead
catalytic converter is coated with
palladium/rhodium while the under
floor catalytic converter is plat
inum/rhodium-plated. The longevity
of the exhaust system is provided by
the use of stainless steel
throughout.
Exhaust system
The catalytic converter system
incorporates one bulkhead and one
underfloor catalytic converter (both made from thin-wall ceramic) in
each exhaust stream. Downstream
of the separation point of the two
catalytic converter systems, the
exhaust streams are combined in
the center muffler. Further on, the
exhaust flow continues in twin pipes
to the two rear mufflers.
The AMG sports exhaust system
ends in two chrome-plated twin
tailpipes bearing the AMG logo.
