8. Mercedes 73 SL AMG
As an integral part of the Mercedes Benz company from the late ’90s, AMG had access to all Mercedes models and development resources. So, it started to expand to all classes including the famous and well-known SL range. Since the SL always had a special place in Mercedes’s nomenclature, AMG had to take extra care of this model.
The factory 6.0-liter V12 engine wasn’t good enough, so AMG tuned it to 7.3-liters with the power output of 525 HP. It basically was a supercar they disguised as a luxury roadster. However, the price was high and availability was limited, so AMG only made 85 of them. Interestingly, the engine lived on in the Pagani Zonda supercar and as an experienced engineer, Horacio Pagani praised its power and torque.
