Brain-cramping amounts of info about BMW M5's V10 engine

It's more than you could ever hope for— both the engine and its explication. Not only are there the typical horsepower and torque figures, there are power charts, piston behavior explained, cylinder heads described, material science discussed, and pictures showing the engine from every angle. The basic gist of the story for the non-mechanical engineers out there is that the new M5 is going to be awesome, due in large part to all of the technology put to use in the engine room. And despite the inherent complexity of a 500-hp V10, BMW feels they've paid such incredible attention to every minute aspect that engine maintenance will actually be reduced.
