The Alfa Romeo A6.000 is a 5,998 cc, V12 naturally aspirated petrol engine produced between 2016 and 2023. Developed for the limited-production Alfa Romeo 8C Competizione and its successor, the 8C Spider, the A6.000 delivers exceptional power and a high-revving character. It features DOHC valvetrain, variable valve timing, and direct fuel injection, producing 405 kW (550 PS) at 7,000 rpm and 570 Nm of torque at 4,750 rpm.
Fitted exclusively to the 8C Competizione (940) and 8C Spider (944) platforms, the A6.000 was engineered for high-performance grand touring with a focus on throttle response, acoustic refinement, and driving engagement. Emissions compliance is achieved through precision-mapped direct injection and dual three-way catalytic converters, meeting Euro 6b standards throughout its production run.
One documented concern is premature carbon buildup on intake valves, highlighted in Alfa Romeo Technical Bulletin 08/2019. This issue arises due to the absence of port injection in the direct-injected setup, particularly affecting vehicles with frequent short-trip usage. Revised ECU fueling strategies introduced in 2020 reduced deposit accumulation, while recommended induction service intervals were formalized in SIB 08/2019.
All production years (2016–2023) meet Euro 6b emissions standards (VCA UK Type Approval #VCA/EMS/8891).
The Alfa Romeo A6.000 is a 5,998 cc V12 naturally aspirated petrol engine engineered for high-performance grand tourers (2016–2023). It combines direct fuel injection with variable valve timing to deliver high-revving power and refined throttle response. Designed to meet Euro 6b standards, it balances exotic performance with emissions compliance for European markets.

The naturally aspirated V12 provides linear power delivery and high-RPM excitement ideal for spirited driving, but requires strict adherence to 15,000 km oil change intervals using 5W-40 full-synthetic to protect high-load camshafts and timing chains. SAE 5W-40 meeting ACEA A3/B4 is essential due to high combustion temperatures and sustained engine speeds. Use of fuel below 98 RON may trigger knock sensor adaptation and reduce peak output. Carbon buildup on intake valves is common in low-mileage or short-trip vehicles; induction cleaning every 40,000 km is advised per Alfa Romeo SIB 08/2019. Dual catalytic converters require inspection for thermal degradation, especially in high-temperature environments.
Oil Specs: Requires SAE 5W-40 meeting ACEA A3/B4 (Alfa Romeo SIB 08/2019). Supersedes API SN/CF.
Emissions: Euro 6b applies to all models (2016–2023) (VCA #VCA/EMS/8891). No Euro 6c or RDE compliance required due to low-volume production exemption.
Power Ratings: Measured under UN ECE R83-06. Output requires 98 RON fuel (Alfa Romeo TIS Doc. A940-201).

UN Regulation No 83 (Emissions)
The Alfa Romeo A6.000 was used across Alfa Romeo's 940/944 platforms with longitudinal mounting and shared architecture with Ferrari V12 units under FCA global platform sharing. This engine received platform-specific calibrations-intake tuning in the 8C Competizione and revised cooling in the 8C Spider-and from 2020 the facelifted 8C LCI adopted updated emissions controls, creating partial interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the rear-left cylinder block near the transmission bellhousing (Alfa Romeo TIS A940-201). The 8th VIN digit indicates engine family ('H' for V12 petrol). Pre-2020 models have silver valve covers; post-2020 units use black. Critical differentiation: intake manifold design changed in 2020 to improve airflow; pre-2020 parts are not compatible with later ECU calibrations. Service parts require production date verification—timing kits for engines before 01/2020 are incompatible with post-2020 control modules (Alfa Romeo SIB 08/2019).
The A6.000's primary reliability risk is intake valve carbon buildup, with elevated incidence in low-mileage ownership. Internal FCA quality reports from 2021 noted increased intake restriction in urban-driven 8C models, while UK DVSA records show elevated lambda sensor faults in vehicles with infrequent highway use. Short-trip cycles and low-RON fuel increase deposit formation and knock sensor stress, making fuel quality and induction service adherence critical.
