The Porsche MCY.PA is a 2,894 cc, twin‑turbocharged V6 petrol engine introduced in 2023 for the second‑generation Macan lineup. It features port and direct fuel injection (PD‑FI), variable valve timing (VarioCam Plus), and a dry‑sump lubrication system optimized for compact transverse packaging. In current applications it delivers 260 kW (354 PS) and 500 Nm of torque, with peak torque available from 1,750 rpm for responsive urban and highway driving.

The Porsche MCY.PA is a 2,894 cc twin‑turbocharged V6 engineered for compact SUV applications (2023–present). It combines port and direct injection with a dry‑sump system to deliver immediate torque and high‑load stability. Designed to meet Euro 6d, it balances dynamic response with regulatory compliance in the new Macan platform.

The Porsche MCY.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 dry‑sump reservoir—for the Macan S. From Q4 2023, the high‑pressure fuel pump was upgraded to a reinforced diaphragm variant, creating minor production splits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The MCY.PA's primary reliability risk is high‑pressure fuel pump diaphragm fatigue under sustained high‑load, high‑ambient conditions, with internal Porsche diagnostics (2023) indicating a 6% incidence rate in pre‑Q4‑2023 Macan S vehicles operated above 35 °C with frequent mountain or track use. No secondary damage occurs, but drivability and emissions compliance degrade. The revised pump resolves this issue completely.

The most common questions about engine codes, what they mean, how to find them and how this database works
The MCY.PA is robust with proper maintenance. Early builds (pre-Q4-2023) had HPFP diaphragm wear under extreme heat and load, now resolved with reinforced hardware. With RON 98 fuel, Porsche C4 oil, and standard service intervals, it offers strong longevity. Dry-sump design enhances reliability in aggressive driving scenarios.
Main concerns are HPFP diaphragm failure in pre-late-2023 engines, GPF saturation from short trips, turbo oil coking after hot shutdowns, and minor oil cooler line seepage. All are documented in Porsche bulletin PA-23-098. Most are avoidable with cooldown discipline and updated parts.
Exclusively the PA2-generation Macan S (2023–present). This engine is not used in base Macan, Macan GTS, Taycan, or any other Porsche model. It was developed specifically for the transverse architecture of the new Macan platform to replace the Audi-sourced V6.
Aftermarket ECU tuning is common on the MCY-PA platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Approximately 10.6 L/100km combined (official WLTP). Real-world mixed driving yields 9.2–12.0 L/100km; highway cruising can achieve 8.0 L/100km. Official figure is 27 mpg UK combined. Turbocharging and GPF system inherently limit efficiency despite advanced injection.
Yes. Like all modern Porsche V6s, the MCY.PA is an interference design. Timing chain failure—though extremely unlikely due to redundant tensioners—could cause valve-piston contact. The system is engineered for full engine life under normal conditions.
Porsche C4 (0W‑40) synthetic oil is mandatory. It ensures high-temperature film strength for the dry-sump system and turbo bearing protection. Oil changes are recommended every 15,000 km or annually. Non-approved oils risk HPFP wear and turbo coking.
