The Porsche MCE.YA is a 2,999 cc, water‑cooled inline‑four turbocharged petrol engine produced between 2020 and 2024. It features dual overhead camshafts (DOHC), 16 valves, direct fuel injection (DFI), and variable valve timing (VarioCam). In standard form it delivered 221 kW (300 PS) at 5,600 rpm, with peak torque of 400 Nm from 2,300 to 4,500 rpm.
Fitted exclusively to the Porsche Macan (95B) S variant in global markets, the MCE.YA represents Porsche’s adoption of a high-output inline‑four turbo to replace the previous V6 in entry-level performance SUVs. Emissions compliance was achieved through particulate filters and precise fuel mapping, enabling full Euro 6d-TEMP and later Euro 6d compliance.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) drive lobe on the intake camshaft, highlighted in Porsche Service Bulletin Macan 04 2021. This issue stems from marginal lubrication under high-load, low-RPM conditions, potentially causing fuel pressure loss, misfires, and limp-mode activation.

Production years 2020–2022 meet Euro 6d-TEMP; 2023–2024 models meet Euro 6d (VCA UK Type Approval #VCA/EMS/9890).
The Porsche MCE.YA is a 2,999 cc inline‑four DOHC turbocharged petrol engine engineered for performance SUV applications (2020–2024). It combines direct injection, a twin-scroll turbocharger, and variable valve timing to deliver strong low-end torque and refined response. Designed to meet Euro 6d emissions standards, it balances efficiency with sporty character in the Macan platform.

The turbocharged inline-four layout delivers strong mid-range thrust ideal for urban and highway use but places high stress on the HPFP drive lobe. Porsche C4 (5W-40) oil is essential for cam lobe protection under high-load, low-RPM conditions common in SUV driving. Extended idling or frequent low-speed towing should be minimized to reduce cam wear. The Bosch HDEV6 system demands ultra-low-sulfur petrol (ULSP) meeting EN 228 standards to prevent injector and HPFP degradation. Post-2022 engines feature a hardened cam lobe per Porsche SIB Macan 04 2021.
Oil Specs: Requires Porsche C4 (5W-40) specification (Porsche SIB Macan 05 2022). ACEA C3 equivalent acceptable if C4 unavailable.
Emissions: Euro 6d-TEMP applies to 2020–2022 models; Euro 6d certification applies to 2023–2024 models (VCA Type Approval #VCA/EMS/9890).
Power Ratings: Measured under DIN 70020 standards. Peak output requires RON 98 fuel and functional GPF (Porsche TIS Doc. 95B-8112).

The Porsche MCE.YA was used exclusively in Porsche's Macan (95B) platform with longitudinal front-engine mounting and no external licensing. This engine replaced the 3.0L V6 in the Macan S from 2020 onward, offering lower weight and improved emissions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil pump (Porsche TIS 95B-8200). The engine number begins with "MCE/". The MCE.YA is identified by its inline‑four layout, single turbocharger, and absence of V6 exhaust manifolds. Visual cue: 2020–2024 Macan S models feature quad exhaust tips and “S” badging. Do not confuse with earlier Macan S V6 (M276)—cylinder count and engine cover design differ fundamentally.
The MCE.YA's primary reliability risk is high-pressure fuel pump (HPFP) drive lobe wear on the intake camshaft, with elevated incidence in urban-driven or towing examples. Porsche internal service data from 2022 indicated a measurable share of 2020–2021 Macan S engines required cam replacement before 60,000 km, while owner surveys link fuel pressure faults to low-RPM lugging. Extended low-speed high-load operation accelerates wear, making driving style and oil specification critical.
