The V8 in the M3 (S65) is quite light for all the tech it has (Double over-head cams, double-vanos variable valves, a seperate throttle body for each cylinder), with a weight of 202kg, 15kg less than the M3 E46 six. For it's displacement, it has an excellent torque curve from low down, and can of course rev to 8400rpm, which makes for a tremendously wide usable power band. Agreed, that's not really less than an LS2, but the M3 V8 is a much more sophisticated and complicated design, which results in the said advantages. BMW could have made that V8 much bigger without a lot of weight added, but they opted for high revs and superior response.
Of course, the V12 Twin Turbo in the 760i / RR Ghost isn't terribly light, but it's a V12 with two turbos and all technical finesses available. That results in maximum torque from 1500rpm to redline, and manners as smooth as an electric engine, just without the noise.
The new, single twin scroll turbo straight-six in the 335i weighs in at about 180kg.
I don't have the numbers for the Ferrari engines, but they are technically excellent with record-setting power/displacement and torque/displacement numbers. And excuse me, but an LS9 just wouldn't fit such a car.
