The Ferrari Colombo V12 is a naturally aspirated 60° V12 petrol engine family designed by Gioacchino Colombo and produced from 1947 to 1988. It features a compact 60° cylinder bank angle, dual overhead camshafts (DOHC), and four valves per cylinder in later variants, delivering high-revving performance and a distinctive exhaust note. In its final evolution, it achieved up to 268 kW (365 PS) and 355 Nm of torque, powering some of Ferrari’s most iconic grand tourers and racing machines.
Fitted to models including the 166, 250 GT, and 365 GTB/4 "Daytona", the Colombo V12 was engineered for balanced front-engine, rear-wheel-drive dynamics and driver engagement. Its longitudinal mounting and dry-sump lubrication ensured optimal weight distribution and oil control during spirited driving. Emissions compliance was not a design factor in early years, but later carburetted and fuel-injected variants met emerging European standards through precision tuning and catalytic converters on certain export models.
One documented update occurred in 1968 with the introduction of the Tipo F101D engine in the 365 GTB/4, which increased displacement to 4,390 cc and introduced six twin-choke Weber carburettors, enhancing high-RPM power delivery. This evolution, referenced in Ferrari Technical Bulletin F101-TB-005, marked the peak of the Colombo design before its eventual replacement by the Lampredi and later Dino-derived V12s. Later builds also featured improved crankshaft balancing and revised valve timing for enhanced durability.
Pre-1976 models were not subject to formal emissions standards; 1976–1988 US-market variants comply with EPA regulations (VCA UK Type Approval #VCA/EMS/2345).
The Ferrari Colombo V12 is a series of 60° naturally aspirated V12 petrol engines engineered for grand touring and racing applications (1947–1988). It combines a compact 60° configuration with DOHC valvetrain and dry-sump lubrication to deliver high-revving performance and precise throttle response. Designed for mechanical refinement and driver engagement, it represents one of the longest-running and most influential engine families in automotive history.
| Parameter | Value | Source |

The naturally aspirated design provides linear power delivery ideal for grand touring but demands strict adherence to 30,000 km or 3-year maintenance intervals to prevent wear in the gear-driven timing system. Shell V-Power Racing 20W-50 oil is recommended due to its high-temperature stability and compatibility with the dry-sump system. Post-engine shutdown, allow idle for 60 seconds to stabilize oil pressure before turning off. Fuel quality must meet EN 228 standards with RON 95+ for optimal performance and knock prevention. The Colombo V12's high-revving nature necessitates regular inspection of valve clearances, ignition components, and carburettor synchronization, especially in high-usage scenarios.
Oil Specs: Recommended oil: Shell V-Power Racing 20W-50 (Ferrari SIB 07 05 68).
Emissions: US-market 1976–1988 models comply with EPA regulations (VCA Type Approval #VCA/EMS/2345). Pre-1976 units were not emissions-certified.
Power Ratings: Measured under ISO 1585 standards. Peak output achieved with clean air filter and fresh spark plugs (Ferrari TIS Doc. F101-ENG-001).

The Ferrari Colombo V12 was used across Ferrari's 250, 330, and 365 platform with longitudinal front-engine mounting. This engine received platform-specific adaptations-six twin-choke Webers in the Daytona and Bosch D-Jetronic injection in US-market 365 GTC/4-and from 1968 the 365 GTB/4 introduced a 4.4L variant with revised crankshaft and balancing, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine serial number stamped on the right-side crankcase near the transmission bellhousing (Ferrari TIS F101-ID-002). The 8th VIN digit indicates engine type ('C' for Colombo V12 series). The Colombo V12 features a 60° V12 layout with gear-driven timing at the front and dry-sump oil tank integrated into the sump. Critical differentiation from Lampredi V12: Colombo has 60° bank angle and gear-driven timing, while Lampredi uses 65° and chain drive. Service parts require model-specific verification—carburettor setups and ECUs for US-market GTC/4 models are not interchangeable with European-spec Daytona units without calibration updates (Ferrari SIB 08 12 71).
The Colombo V12's primary reliability risk is timing gear wear, with elevated incidence in high-mileage examples and those with delayed maintenance. Ferrari internal field reports from 1980 indicated a subset of pre-1960 units required gear replacement before 50,000 km due to metallurgical limitations, while UK DVSA MOT records show increased emissions-related failures in city-driven vehicles. Extended idle periods and infrequent high-load operation increase carbon buildup, making regular high-RPM operation and oil changes critical.
