Yes and manufacturers NEVER lie about their own vehicles. Now that is comical. You do realize that marketing folks have say over a spec sheet, not engineers. Not only is the M3 engine more compact but they entire car was the result of a pretty good obsession by its engineers and designers on control of weight gain. There are enough hollow parts on the car including the engine to save some significant weight. Mercedes obsession over weight was obviously quite a bit less with the C63 and other vehicles that use the same engine. To believe that these specs are absolutely apples to apples is a big stretch in my opinion.
