slk55 2006 355 hp vs 2005 362hp
Regardless, the SLK55 has always been 355hp in US. Some of the reviews picked up the 362 number early on from the MB european marketing literature, that added to the confusion.
When the E55 came out they made the HP lower for marketing reasons but the HP is the same as the SL,CL,S when you put in on a dyno.
