The Porsche MCW.CA is a 2,894 cc, twin‑turbocharged V6 petrol engine produced between 2020 and 2024. It features direct fuel injection, DOHC with variable valve timing (VarioCam Plus), and a dry‑sump lubrication system. In standard form it delivers 260–280 kW (354–381 PS) and 500–520 Nm of torque, engineered for responsive performance in compact SUV applications.
Fitted exclusively to the 9YA-generation Macan GTS and select Macan S trims, the MCW.CA was developed as a high-output evolution of the EA839 V6 family tailored for transverse mounting. Emissions compliance was achieved through gasoline particulate filters (GPF), dual lambda sensors, and precise fuel control, allowing full Euro 6d compliance across all production years.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) plunger assembly under sustained high-temperature operation, highlighted in Porsche Technical Bulletin PTB‑2022‑07. This stems from thermal stress on the pump’s cam follower interface during repeated aggressive acceleration cycles, particularly in vehicles used for canyon or track driving.
All production years (2020–2024) meet full Euro 6d standards (VCA UK Type Approval #VCA/EMS/POR2024).
The Porsche MCW.CA is a 2,894 cc twin‑turbo V6 petrol engine engineered for the transverse-mounted Macan platform (2020–2024). It integrates Bosch HDP6 direct injection with twin BorgWarner turbochargers to deliver immediate torque and linear throttle response. Designed to meet Euro 6d emissions standards, it features gasoline particulate filtration and adaptive combustion control for clean, dynamic operation.

The MCW.CA delivers strong mid-range torque and agile throttle response ideal for dynamic urban and highway driving. However, the transverse layout and compact engine bay increase under-hood temperatures, accelerating HPFP wear in early units. RON 98 fuel and strict adherence to 15,000 km oil intervals with Porsche C4 0W-40 are essential. Extended high-load use requires a 30–60 second cooldown to prevent turbo bearing coking. GPF regeneration is passive but may require forced cycles after repeated short trips. Pre-2022 units should be inspected for HPFP wear per PTB-2022-07.
Oil Specs: Requires Porsche C4 0W-40 (ACEA C3-aligned) or Porsche A40 5W-40 (Porsche Lubricants Guide 2023).
Emissions: Full Euro 6d compliance for all 2020–2024 models (VCA Type Approval #VCA/EMS/POR2024).
Power Ratings: Measured per ECE R85. Power figures assume RON 98 fuel quality (Porsche PIWIS Doc. ENG-MCW-2020).

EU Regulation (EU) 2017/1151
The Porsche MCW.CA was used exclusively in the 9YA-generation Macan platform with transverse mounting and no external licensing. This engine features platform-specific intake manifolds, reinforced motor mounts, and revised oil pan geometry for all-wheel-drive integration. From mid-2022, Porsche introduced an updated HPFP with enhanced plunger metallurgy, creating service part distinctions documented in technical bulletins.
Engine code MCW.CA is stamped on the front face of the engine block near the timing cover (Porsche PIWIS ENG-ID-04). VIN 7th digit 'G' or 'H' indicates V6 petrol in 9YA Macan. Pre-2022 models use HPFP with part number 06K127025G; post-2022 use revised 06K127025K with improved thermal durability. Visual cue: black composite valve covers with 'V6 TwinTurbo' embossing. Do not confuse with MCT series (longitudinal V8) or MCR.CA (longitudinal V6 in Panamera/Cayenne). HPFP replacement on pre-2022 units must follow PTB-2022-07.
The MCW.CA's primary reliability risk is HPFP plunger wear in early builds, with elevated incidence in aggressive or hot-climate driving. Porsche internal quality data from 2022 indicated a measurable uptick in HPFP replacements before 60,000 km in performance-driven vehicles, while UK DVSA statistics show minimal emissions-related MOT failures due to robust GPF control. The transverse layout increases thermal load on the fuel system, making oil quality and cooldown protocol critical.
