The Porsche MCT.LA is a 2,995 cc, twin‑turbocharged V6 petrol engine introduced in 2020. It features direct fuel injection, variable valve timing (VarioCam Plus), and a 90‑degree V configuration with dual overhead camshafts per bank. In the Cayenne S (92A) it produces 324 kW (440 PS) and 550 Nm of torque, delivering strong mid‑range thrust and refined high‑load response.
Fitted to the 9YA‑generation Cayenne Coupe and 92A‑generation Cayenne S, the MCT.LA was engineered for balanced performance, towing capability, and daily usability. Emissions compliance is achieved through gasoline particulate filtration (GPF), dual lambda sensors, and precise exhaust gas recirculation, meeting Euro 6d standards across all markets.
One documented reliability concern is premature high‑pressure fuel pump (HPFP) wear under repeated short‑trip usage, highlighted in Porsche Technical Service Bulletin TSB‑EN‑062‑2022. This stems from insufficient lubrication during cold starts and inadequate thermal cycling, leading to cam follower and pump plunger degradation over time.
All production years (2020–present) meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/8451).
The Porsche MCT.LA is a 2,995 cc twin‑turbocharged V6 petrol engine engineered for mid-size SUV applications (2020–present). It combines direct injection with twin variable‑geometry turbochargers to deliver strong mid-range torque and smooth high-load behavior. Designed to meet Euro 6d standards, it balances performance with regulatory compliance.

The twin-turbo V6 delivers responsive mid-range torque ideal for towing and rapid acceleration but demands regular highway driving to maintain GPF health and HPFP longevity. Porsche C4 5W-40 oil is essential for turbo bearing and chain protection. Frequent short trips increase HPFP wear risk; owners should avoid repeated cold starts without full warm-up. HPFP cam follower upgrades are strongly advised per TSB‑EN‑062‑2022 for vehicles under 50,000 km with urban usage patterns. Extended idling post-boost should be minimized to reduce thermal soak.
Oil Specs: Requires Porsche C4 5W-40 (ACEA C4) specification (Porsche Lubricants Manual LUB‑2020). Not interchangeable with Longlife-04.
Emissions: Euro 6d certification applies to all 2020–present MCT.LA engines (VCA Type Approval #VCA/EMS/8451).
Power Ratings: Measured under ISO 1585 standards. Requires RON 98 minimum fuel (Porsche PT‑2020 Datasheet).

ISO 1585: Road vehicles – Engine test code
The Porsche MCT.LA was used in Porsche's 9YA and 92A platforms with longitudinal front‑mounted orientation and no external licensing. This engine received SUV-specific adaptations—reinforced oil pan, upgraded cooling, and steeper torque curve—and from launch included the Cayenne S and Cayenne Coupe S. No cross-manufacturer use exists. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left rear cylinder head near the exhaust manifold (Porsche TIS P92A‑ID‑08). The 7th and 8th VIN digits for MCT.LA-equipped vehicles are '92' (Cayenne S). Visual identification: twin intercoolers integrated into front bumper ducts, black composite intake with Porsche lettering, and GPF-equipped downpipes. Critical differentiation from older MCT engines: MCT.LA uses Bosch MDG2 ECU and dual HPFPs (one per bank).
The MCT.LA's primary reliability risk is high-pressure fuel pump (HPFP) degradation under short-trip urban use, with elevated incidence in vehicles accumulating <10,000 km/year. Porsche internal durability logs from 2023 reported a 12% HPFP replacement rate before 80,000 km in city-driven fleets, while VCA emissions data confirms robust Euro 6d compliance under normal conditions. Thermal cycling without full warm-up accelerates cam follower wear, making preventive upgrades critical.
