Well let's analyze the weasel words, shall we?
They're just saying "6-cylinder", not specifically an Inline-6, so it could be the much more common V-6 too. They also didn't say "BMW" 6-cylinder, so we can assume they could be comparing with non-BMW engines. Basically it sounds like they're comparing it with naturally aspirated V-6 engines from companies like MB, Audi, and the Japanese. I'm sure the engine is indeed lighter than the common V-6 engines, but NOT lighter than the N52. Otherwise why not say that it's lighter than the N52?
I'm guessing the N52 is probably the lighter engine. Two more cylinders, but no need for balance shafts, magnesium alloy block vs aluminum, and no turbos and associated plumbing and intercooler.
