The Porsche MCV.VC is a 2,894 cc, V6 twin-turbo petrol engine produced between 2017 and 2023. It features a 90-degree bank angle, direct fuel injection, dual overhead camshafts (DOHC), and two mono-scroll turbochargers arranged in a hot-V layout between the cylinder banks. In standard tune it delivers 250–260 kW (340–354 PS) with torque spanning 450–500 Nm, offering refined performance with strong mid-range response.
Fitted to the Panamera (G2) and Cayenne (E2) platforms, the MCV.VC was engineered for luxury performance applications, balancing smooth power delivery with emissions compliance. Emissions adherence was achieved via port-assisted direct injection, variable valve timing on intake and exhaust, and a close-coupled three-way catalytic converter, ensuring compliance with Euro 6d-TEMP and later Euro 6d standards from launch.
A documented concern involves premature wear of the high-pressure fuel pump (HPFP) drive pinion, potentially causing hard starts and misfires. This issue, addressed in Porsche Service Information Bulletin 9135/2020, is linked to thermal stress and marginal metallurgy in early production batches. From 01/2021, Porsche implemented an updated HPFP actuator and reinforced camshaft lobe profile.
All production years (2017–2023) meet Euro 6d-TEMP or Euro 6d standards (VCA UK Type Approval #VCA/EMS/8912).
The Porsche MCV.VC is a 2,894 cc V6 twin-turbo petrol engineered for executive sedans and SUVs (2017–2023). It combines a hot-V twin-turbo architecture with port and direct injection to deliver linear power and responsive torque. Designed to meet Euro 6d from 2020 onward, it integrates advanced emissions controls without compromising drivability.

The hot-V turbo layout minimizes lag but elevates under-hood temperatures, increasing thermal stress on the HPFP drive mechanism. Use only EN 228-compliant RON 95+ fuel. Porsche C3 (0W‑40) oil is mandatory—non-compliant oils accelerate HPFP and turbo wear. Oil changes every 15,000 km or 12 months are critical. Pre-01/2021 engines should be inspected per SIB 9135/2020. Port injection mitigates intake valve coking, reducing maintenance compared to pure GDI engines.
Oil Specs: Requires Porsche C3 (0W‑40) specification (Porsche SIB 9150/2017). Equivalent to ACEA C3 and BMW LL‑04.
Emissions: Euro 6d-TEMP applies to 2017–2019; Euro 6d to 2020–2023 (VCA Type Approval #VCA/EMS/8912). All UK-market units comply.
Power Ratings: Measured under ISO 1585. 260 kW output requires RON 98 fuel (Porsche TIS Doc. G2-ENG-210).

ISO 1585: Road vehicles – Engine test code
The Porsche MCV.VC was used across Porsche's G2 and E2 platforms with longitudinal front-engine mounting and exclusively in luxury performance applications. This engine received platform-specific cooling upgrades in the Cayenne and revised engine mounts in the Panamera. From 2020, updated emissions calibration for Euro 6d introduced minor ECU differences, affecting software compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the rear of the left cylinder bank near the exhaust manifold (Porsche TIS G2-ENG-215). The 7th VIN digit is ‘V’ for MCV.VC applications. Pre-2021 engines use HPFP part number 9A2.128.156.00; post-2021 units use 9A2.128.156.01 with reinforced pinion. Visual ID: silver valve covers with ‘Porsche’ in relief; twin downpipes visible from below. ECU is Bosch MDG8 mounted near firewall—calibration files differentiate 340 PS vs 354 PS variants.
The MCV.VC's primary reliability risk is high-pressure fuel pump drive pinion wear on pre-2021 builds, with elevated incidence in high-ambient-temperature regions and frequent short-trip driving. Porsche internal field data from 2021 indicated a notable rate of HPFP-related repairs before 75,000 km in affected batches, while UK DVSA records show minimal emissions-related failures due to robust GPF and catalyst integration. Thermal stress and fuel quality make adherence to OEM oil and petrol specifications critical.
Analysis derived from Porsche technical bulletins (2017–2023) and UK DVSA failure statistics (2019–2023). Repair procedures should follow manufacturer guidelines.
