The Porsche MCR.CA is a 2,995 cc, twin‑turbocharged V6 petrol engine produced between 2017 and 2023. It features direct fuel injection, DOHC with variable valve timing (VarioCam Plus), and an integrated dry‑sump lubrication system. In standard form it delivers 250–260 kW (340–354 PS) and 450–500 Nm of torque, offering strong mid‑range response ideal for the Panamera and Cayenne.
Fitted to the 971 — generation Panamera (V6 models) and 92A — generation Cayenne, the MCR.C…
Production years 2017–2019 meet Euro 6d-TEMP standards; 2020–2023 models meet full Euro 6d (VCA UK Type Approval #VCA/EMS/POR2022).
The Porsche MCR.CA is a 2,995 cc twin‑turbo V6 petrol engine engineered for luxury performance sedans and SUVs (2017–2023). It combines direct injection with twin variable‑geometry turbochargers to deliver smooth, high-torque performance across the rev range. Designed to meet Euro 6d-TEMP and Euro 6d standards, it integrates GPFs and advanced engine management for clean operation.

The Porsche MCR.CA was used across Porsche's 971 and 92A platforms with longitudinal mounting and shared architecture with the Audi EA839 V6 family. This engine received platform-specific adaptations—revised cooling ducts in the 971 Panamera and reinforced mounts in the 92A Cayenne—and from 2020 the updated HPFP design, creating service part distinctions. Licensing permitted shared components with Audi and Volkswagen Group V6 applications, though calibration and ancillaries differ. All adaptations are documented in OEM technical bulletins.
The MCR.CA's primary reliability risk is high-pressure fuel pump (HPFP) wear in early builds, with elevated incidence in track or sustained high-load use. Porsche internal service data from 2021 indicated a measurable uptick in HPFP replacements before 80,000 km in performance-driven vehicles, while UK DVSA statistics show minimal emissions-related MOT failures thanks to robust GPF control. Extended high-temperature operation without cooldown makes HPFP longevity and oil quality critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
Generally yes—when maintained properly. Early engines (2017–2019) have HPFP concerns under hard use, but post-2020 updates resolved this. With correct oil (Porsche C4 0W-40), quality fuel, and periodic high-speed driving for GPF regeneration, the MCR.CA offers robust performance and longevity.
HPFP wear in early models, turbo oil coking from hot shutdowns, GPF saturation from short trips, and minor valve cover seepage. All are documented in Porsche service bulletins, and most are preventable with proper driving habits and maintenance.
Primarily the 2017–2023 Panamera (971) V6 and 2018–2023 Cayenne (92A) V6—including Panamera 4, Panamera 4S (V6), Cayenne, and Cayenne S (V6). It is not used in Macan or 911 models.
Yes. Stage 1 ECU remaps typically yield +30–50 kW safely with stock turbos and intercoolers. Higher stages require upgraded intercoolers, exhaust, and possibly fuel system support. HPFP reliability must be confirmed before tuning, especially on pre-2020 units.
In combined driving, expect 10.5–12.0 L/100km (24–22 mpg UK) for the Cayenne and 10.0–11.5 L/100km (28–25 mpg UK) for the Panamera. Highway cruising can drop to ~8.5 L/100km (33 mpg UK). Real-world figures vary significantly with driving style.
Yes. Like all modern Porsche DOHC engines, the MCR.CA is an interference design. Timing chain failure—though extremely rare—could cause piston-to-valve contact and severe damage. However, the chain is robust and designed for life with proper oil changes.
Porsche specifies C4 0W-40 (or A40 5W-40) synthetic oil meeting Porsche approval standards. Use only Porsche-approved oils to ensure HPFP lubrication, turbo protection, and GPF compatibility. Change every 15,000 km or annually.
