The Porsche MDC.NA is a 3,996 cc, twin‑turbocharged V8 petrol engine introduced in 2024. It features direct fuel injection, variable valve timing (VarioCam Plus), and a 90‑degree V configuration with dual overhead camshafts per bank. In the Panamera Turbo E‑Hybrid (G2 II) it produces 450 kW (610 PS) and 850 Nm of torque, engineered for high-performance hybrid propulsion and refined daily usability.
Fitted to the updated G2 II‑generation Panamera Turbo E‑Hybrid, the MDC.NA was developed for seamless integration with Porsche’s 400V electric drive system, balancing explosive mid-range thrust with low NVH characteristics. Emissions compliance is achieved through gasoline particulate filtration (GPF), dual lambda sensors, and exhaust gas recirculation, meeting Euro 6d standards across all markets.
One documented concern is early carbon buildup on high-pressure fuel injector tips under repeated short‑trip urban use, highlighted in Porsche Technical Service Bulletin TSB‑EN‑124‑2025. This stems from incomplete combustion cycles and insufficient injector self‑cleaning temperatures, leading to lean misfires and rail pressure instability.
All production years (2024–present) meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9721).
The Porsche MDC.NA is a 3,996 cc twin‑turbocharged V8 petrol engine engineered for plug-in hybrid executive sedans (2024–present). It combines direct injection with twin variable-geometry turbochargers to deliver immediate torque response and sustained high-load capability. Designed to meet Euro 6d standards, it supports 400V hybrid systems while maintaining regulatory compliance.

The twin-turbo V8 delivers immediate torque and refined high-load performance but requires regular highway driving to prevent injector carbon buildup and maintain GPF health. Porsche C4 0W-40 oil is essential for turbo bearing and chain protection. Frequent short urban trips increase injector fouling risk; vehicles used primarily in cities should undergo injector cleaning at 30,000 km per TSB‑EN‑124‑2025. Extended idling after boost should be minimized to reduce thermal soak. Highway driving for 20+ minutes weekly is recommended to enable passive GPF regeneration and injector self-cleaning.
Oil Specs: Requires Porsche C4 0W-40 (ACEA C4) specification (Porsche Lubricants Manual LUB‑2024). Not interchangeable with Longlife-04.
Emissions: Euro 6d certification applies to all 2024–present MDC.NA engines (VCA Type Approval #VCA/EMS/9721).
Power Ratings: Measured under ISO 1585 standards. Requires RON 98 minimum fuel (Porsche PT‑2024 Datasheet).

ISO 1585: Road vehicles – Engine test code
The Porsche MDC.NA was used in Porsche's G2 II platform with longitudinal front‑mounted orientation and no external licensing. This engine received hybrid-specific adaptations—reinforced oil pan for electric motor integration, revised exhaust manifolds for packaging, and updated ECU calibration—and from launch included only the Panamera Turbo E‑Hybrid. No cross-manufacturer use exists. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left rear cylinder head near the exhaust manifold (Porsche TIS G2II‑ID‑11). The 7th and 8th VIN digits for MDC.NA-equipped vehicles are 'G2'. Visual identification: black anodized intake manifold with central 'Turbo S' badge, twin intercoolers integrated into front bumper ducts, and GPF-equipped downpipes. Critical differentiation from MCV.VA: MDC.NA uses updated Bosch HDP7 injectors and is exclusively paired with the 190 kW electric motor in the G2 II Turbo E-Hybrid. ECU ID: Bosch MDG5 with software version ≥24.2.
The MDC.NA's primary reliability risk is high-pressure fuel injector carbon buildup under repeated short-trip urban use, with elevated incidence in vehicles accumulating <12,000 km/year in dense city environments. Porsche internal diagnostics data from Q2 2025 showed 13% of G2 II Turbo E-Hybrids required injector service before 28,000 km, while VCA emissions logs confirm full Euro 6d compliance under standard use. Incomplete combustion cycles prevent injector self-cleaning, making preventive cleaning critical for urban owners.
Analysis derived from Porsche technical bulletins (2024–2025) and UK DVSA failure statistics (2024–2025). Repair procedures should follow manufacturer guidelines.
