The Porsche MCX.PA is a 2,894 cc, twin‑turbocharged V6 petrol engine introduced in 2024 for the updated Macan performance lineup. It features port and direct fuel injection (PD‑FI), variable valve timing (VarioCam Plus), and a compact dry‑sump lubrication system optimized for high‑lateral‑g stability. In current applications it delivers 294 kW (400 PS) and 500 Nm of torque, with a broad torque plateau from 1,800 to 5,500 rpm for responsive daily driving.
Fitted exclusively to the Macan GTS (PA2), the MCX.PA replaces the previous EA839-derived unit with enhanced thermal packaging and revised turbo geometry to suit the tighter engine bay of the all‑electric platform‑derived architecture. Emissions compliance is achieved via a gasoline particulate filter (GPF), cooled exhaust gas recirculation (EGR), and precise engine management calibrated to meet Euro 6d standards across all markets.
One documented concern is intermittent camshaft position sensor signal loss under prolonged high‑temperature soak, highlighted in Porsche Service Bulletin PA‑24‑106. This behavior is linked to early‑batch Hall-effect sensor drift when exposed to underhood temperatures exceeding 120 °C for extended periods. From Q2 2025, Porsche implemented a thermally shielded sensor housing and revised calibration logic.
All production years (2024–present) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/9880).
The Porsche MCX.PA is a 2,894 cc twin‑turbocharged V6 engineered for compact SUV applications (2024–present). It combines port and direct injection with a dry‑sump system to deliver responsive torque and refined high‑load performance. Designed to meet Euro 6d, it balances emissions compliance with dynamic responsiveness in the new Macan platform.

The twin‑turbo V6 provides immediate throttle response and a flat torque curve ideal for urban and highway driving, but requires minimum RON 98 fuel to prevent knock under load. Porsche C4 (0W‑40) oil is mandatory for dry‑sump integrity and high‑temperature turbo protection. Extended idling or high‑ambient operation may induce cam sensor signal drift in pre‑Q2‑2025 builds due to thermal exposure. Revised sensors introduced in mid‑2025 resolve this; earlier units should be inspected if DTCs P0345/P0346 appear. GPF regeneration is automatic but frequent short trips may require occasional extended drives to complete cycles.
Oil Specs: Requires Porsche C4 (0W‑40) specification (Porsche Owner's Manual PA2 Macan GTS). Meets ACEA C3 with Porsche-specific shear stability requirements.
Emissions: Euro 6d certification applies to all 2024–present models (VCA Type Approval #VCA/EMS/9880). Includes real-driving emissions (RDE) compliance.
Power Ratings: Measured under ISO 1585 standards. Full 294 kW output requires RON 98 or higher (Porsche TIS Doc. PPA-MCX-PA-01).

ISO 1585: Road vehicles – Engine test code
The Porsche MCX.PA was developed exclusively for Porsche's PA2 Macan platform with transverse mounting and no third‑party licensing. This engine received specific packaging adaptations—including revised exhaust manifolds for tighter clearances and an integrated oil reservoir for dry‑sump efficiency—in the Macan GTS. From Q2 2025, the camshaft position sensor was upgraded to a thermally shielded variant, creating minor production splits. All adaptations are documented in OEM technical bulletins.
Engine code 'MCX.PA' is laser-etched on the front timing cover near the camshaft sensor bracket (Porsche TIS PPA-ID-04). The 10th VIN digit corresponds to model year; full engine ID is encoded in the QR label on the left strut tower linked to Porsche PIWIS. Pre-Q2-2025 engines use standard Hall-effect cam sensors; post-update units feature thermally shielded housings with part suffix .T2. No other Porsche models use this engine code.
The MCX.PA's primary reliability consideration is camshaft position sensor signal instability under sustained high underhood temperatures, with internal Porsche diagnostics (2024) indicating a 4% incidence rate in pre‑Q2‑2025 Macan GTS vehicles operated in ambient temperatures above 35 °C with frequent stop‑start cycles. No mechanical damage occurs, but drivability and emissions compliance may be affected. The revised sensor housing mitigates thermal drift completely.
