Before the twin-turbo N74<\/a> ushered BMW\u2019s V12 into the boost era, the N73 represented something arguably more ambitious: a naturally aspirated flagship engine that mixed old-school V12 smoothness with then-cutting-edge tech. It debuted in the E65\/E66 7 Series<\/a> as the 760i\/760Li, and it\u2019s widely credited as the world\u2019s first production V12 with gasoline direct injection\u2014a big leap over the outgoing M73.<\/p>\n

What you got in return was the kind of effortless, turbine-like power delivery V12s do best, plus a modern BMW twist: Double VANOS + Valvetronic, paired with direct injection\u2014a combo BMW itself highlighted as a first for the brand on this engine.<\/p>\n

Quick N73 Overview<\/h3>\n

At its core, the N73 is a 60-degree, all-aluminum DOHC V12 that was engineered as a clean-sheet \u201cNew Generation\u201d (NG) BMW development in 6.0-liter form (N73B60) for the 760i\/760Li.\u00a0 A larger derivative, N73B68 (6.75 liters), powered the first-generation Rolls-Royce Phantom VII<\/a> and related Phantom variants for years\u2014one of the more fascinating footnotes in BMW\u2019s modern powertrain history.<\/p>\n

Standout Features That Made the N73 Special<\/h3>\n

1. Direct injection, V12 edition<\/h4>\n

The headline: gasoline direct injection on a production V12\u2014years before DI became mainstream across lineups. BMW\u2019s training material positions DI as a major pillar of the N73\u2019s efficiency and performance goals alongside Valvetronic.<\/p>\n

2. Valvetronic + Double VANOS (a rare pairing on a V12)<\/h4>\n

Unlike the later N74 (which famously doesn\u2019t use Valvetronic), the N73 leaned heavily on BMW\u2019s variable valve tech: bi-VANOS plus variable intake valve lift via Valvetronic.<\/p>\n

3. High system complexity (because flagship)<\/h4>\n

BMW\u2019s own workbook dives into the N73\u2019s additional layers of control hardware around DI\/valvetrain management (it\u2019s a theme you feel any time you service or troubleshoot one).<\/p>\n
