It’s a mystery to us, but somehow this Russian gentleman has obtained and successfully transplanted the heart of a Pagani Zonda into a Mercedies-Benz W123.
In what could be considered the ultimate sleeper, this W123 went from a 2.8L M110 straight-six to a 7.3L AMG M120 V12, producing a colossal 416kW and 720Nm of torque. Power is transmitted through a S73 W140 automatic transmission.
This is quite possibly one of the greatest engine swaps to date. It’s unknown how the owner obtained the engine however, one things for sure, somewhere in the world there’s a Pagani Zonda missing an engine.
