Design, development and variant notes
The P60B40 is a naturally aspirated 4.0-litre racing V8 used by the E46 M3 GTR. The source describes a flat-plane crankshaft and dry-sump lubrication.
Wikipedia gives separate race and road-version ratings. Its engine index calls the fuel system direct injection while the individual P60 article describes multi-port injection; the sources disagree.
