Design, development and variant notes
The N74 is a twin-turbo V12 with direct injection and double-VANOS. Unlike the naturally aspirated N73, it omits Valvetronic; its turbochargers are outside the cylinder banks.
The B60, B66 and B68 versions have different displacement and applications. Later B66 technical-update versions and regional emissions equipment have different quoted outputs.
Variant dimensions and compression
These values are associated with the named variant and source qualifier; equipment and market specifications can differ. A dash means the value is not listed here.
