Mercedes-Benz built the R129 SL from 1988 all the way up to 2001. A regular person who wanted big power would go for the top-of-the-line SL 600. However, if that wasn’t enough, AMG built 85 examples of the SL73 AMG with an engine out of a hypercar.

The Mercedes-Benz SL73 AMG was powered by a 7.3-liter V12 naturally aspirated engine that produced 518 hp @ 5500 rpm and 553 lb-ft of torque @ 4000 rpm. This is the same unit that was later used in the Pagani Zonda.

Collecting Cars currently has one of these iconic Mercs on sale. Moreover, it’s not just a regular SL73 AMG either. This particular car was built for the Sultan of Brunei and has merely 1880 miles on the clock.

Unlike most of the cars from his collection, the SL73 is finished in a rather discreet AMG Diamond Black Metallic with Black leather on the interior. It features the AMG body kit that adds a subtle ducktail spoiler at the back, Recaro seats, an AMG steering wheel, suspension, exhaust and 2-piece 17-inch alloy wheels.

The 1st year of the r129 chassis was not 1988, it was 1990. The 560 Sl was still in play in ’88.
This SL73 has its own specific engine, the pagani zonda has a different version of this engine. You should probably rewrite your title.
How can you lied about the engine, it is not Pagani Zonda engine it’s Mercedes Benz AMG engine installed in Pagani and similar engine is used in Aston Martin,you should apologize and correct your bullshit.
Everyone knows it’s an AMG engine. But, the main talking point here is that it was later used in Pagani Zonda. The same is mentioned in the article.
