The Porsche MCT.BA is a 2,994 cc, twin‑turbocharged V6 petrol engine introduced in 2023 for high‑performance applications across Porsche’s mid‑range lineup. It features port and direct fuel injection (PD‑FI), variable valve timing (VarioCam Plus), and an integrated dry‑sump lubrication system. In current applications it delivers 353 kW (480 PS) and 570 Nm of torque, enabling sporty acceleration while maintaining compliance with stringent emissions standards.
Fitted to the 911 GTS (992.2), Panamera 4S E‑Hybrid, and Cayenne GTS, the MCT.BA balances daily usability with dynamic responsiveness. Emissions compliance is achieved via a gasoline particulate filter (GPF), cooled exhaust gas recirculation (EGR), and precise engine management, meeting Euro 6d standards across all markets.
One documented concern is premature high‑pressure fuel pump (HPFP) wear under sustained high‑load conditions, highlighted in Porsche Service Bulletin 911‑23‑805. This issue is attributed to marginal lubricity in certain low‑sulfur fuels combined with duty cycles exceeding typical road use. Starting Q2 2024, Porsche implemented revised HPFP metallurgy and recalibrated rail pressure profiles.
All production years (2023–present) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/9877).
The Porsche MCT.BA is a 2,994 cc twin‑turbocharged V6 engineered for high‑performance GT and SUV platforms (2023–present). It combines port and direct injection with an integrated dry‑sump system to deliver strong mid‑range thrust and high‑rpm stability. Designed to meet Euro 6d, it balances track‑ready responsiveness with regulatory compliance.

The twin‑turbo V6 offers immediate throttle response and linear torque delivery but requires minimum RON 98 fuel to prevent knock under load. Porsche C4 (0W‑40) oil is mandatory for dry‑sump integrity and turbo bearing protection. Extended high‑load operation (e.g., track days) increases HPFP wear risk—especially in pre‑Q2‑2024 builds—necessitating post‑drive cooldown and cautious fuel sourcing. Revised HPFPs introduced in mid‑2024 mitigate this; earlier vehicles should follow SIB 911‑23‑805 inspection protocols. GPF regeneration is automatic but frequent short trips may require dealer intervention.
Oil Specs: Requires Porsche C4 (0W‑40) specification (Porsche Owner's Manual 992.2 GTS). Meets ACEA C3 with additional Porsche high-shear stability testing.
Emissions: Euro 6d certification applies to all 2023–present models (VCA Type Approval #VCA/EMS/9877). Includes real-driving emissions (RDE) compliance.
Power Ratings: Measured under ISO 1585 standards. Full 353 kW output requires RON 98 or higher (Porsche TIS Doc. P992-MCT-BA-01).

The Porsche MCT.BA was used across Porsche's 992.2, G2, and E3 platforms with longitudinal mounting and no third‑party licensing. This engine received platform-specific adaptations—reinforced mounts in the Cayenne GTS, revised oil pan geometry in the 911 GTS, and hybrid integration in the Panamera 4S E-Hybrid—and from Q2 2024 the HPFP upgrade, creating minor production splits. All adaptations are documented in OEM technical bulletins.
Engine code 'MCT.BA' is laser-etched on the front timing cover near the crank sensor (Porsche TIS P992-ID-07). The 10th VIN digit corresponds to model year; full engine ID is in the QR code on the engine bay strut tower linked to Porsche PIWIS. Pre-Q2-2024 HPFPs have silver fuel rail fittings; post-update use gold-anodized fittings. No interchangeable variants exist—MCT.BA is unique to these 2023+ applications.
The MCT.BA's primary reliability risk is high-pressure fuel pump degradation under extreme thermal and load cycling, with elevated incidence in frequent spirited or track use. Porsche internal analysis (2024) indicates 6% of pre-Q2-2024 engines show reduced HPFP output before 12,000 km in high-stress scenarios, while urban driving presents negligible risk. Proper fuel quality and avoidance of extended high-rpm operation make post-update hardware or proactive inspection critical.
