Won't be SL60.
It'll be SL63 or something.

 

I was reading my Car and Driver and it mentions that Mercedes had the new V12 AMG engine with 4-valves out for a while in car call a parda.

 

The Zonda Pagani?

 

I think that is it. It was blue and look kind of like a viper.

 

I think that's the 7.3L from a while back isn't it?

Yeah it's a 48 valve engine.
48 / 12 = 4

I saw the article about two months ago in a magazine at the store. I thought the engine was new because Mercedes engines have 3 values per piston.
