The Mitsubishi S — AWC Hybrid is a petrol — electric hybrid powertrain combining a 2.0 L MIVEC inline‑four petrol engine with two permanent — magnet AC synchronous electric motors. Total system output is 154 kW (209 PS) with combined torque of 332 Nm, engineered for responsive urban driving and all — electric low — speed operation. It features series — parallel hybrid architecture with regenerative braking and an electronically controlled Super All — Wheel Control (S — AWC)…
All production years 2013–2023 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/5923).
The Mitsubishi S-AWC Hybrid is a 2.0L petrol-electric plug-in hybrid powertrain engineered for compact SUVs (2013–2023). It combines a MIVEC DOHC petrol engine with dual electric motors and an electronically controlled all-wheel-drive system to deliver zero-emission urban driving and all-weather capability. Designed to meet Euro 6 standards, it integrates regenerative braking, engine stop/start, and advanced battery management for stringent emissions control.

The Mitsubishi S-AWC Hybrid was used exclusively in the Outlander PHEV platform with transverse mounting and no external licensing. This powertrain received model-year-specific adaptations—revised battery capacity in the 2019 facelift and updated S-AWC control logic in the 2022 model—and from 2020 the battery cooling system was enhanced, creating minor service part incompatibilities. All adaptations are documented in OEM technical bulletins.
The S-AWC Hybrid's primary reliability risk is traction battery capacity fade in early builds, with elevated incidence in vehicles subjected to frequent DC fast charging or sustained high-ambient-temperature operation. Mitsubishi internal durability reports from 2020 indicated battery degradation exceeding 30% in ~12% of pre-2020 packs before 80,000 km, while UK DVSA MOT records show low emissions failure rates due to robust petrol engine design. Thermal management and charging discipline make battery longevity highly usage-dependent.
Analysis derived from Mitsubishi technical bulletins (2018–2022) and UK DVSA failure statistics (2019–2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The S-AWC Hybrid is generally reliable with proper usage. Early models (2013–2019) had traction battery degradation concerns in hot climates, largely mitigated by 2020 cooling updates. The petrol engine is robust, and the electric drivetrain has few moving parts. Avoid frequent DC fast charging and ensure 12V battery health to maximize longevity.
Top issues include traction battery capacity fade (pre-2020), 12V auxiliary battery failure, rear inverter overheating, and engine oil dilution from short-trip driving. Most are preventable with proper charging habits, regular extended drives, and using OEM 12V batteries. Mitsubishi issued TSB-HV-2019-05 addressing battery thermal management.
The S-AWC Hybrid is used exclusively in the Outlander PHEV: GA generation (2013–2018) and GG generation (2019–2023). Despite marketing names like '2.4 PHEV', the petrol engine remains a 2.0L unit. No other Mitsubishi or cross-manufacturer models use this specific hybrid architecture.
Limited tuning potential due to integrated hybrid control. ECU remaps are not supported by Mitsubishi, and electric motor output is firmware-limited. Aftermarket options are virtually nonexistent due to high-voltage safety and system interdependence. Most owners focus on maintaining battery health rather than power increases.
In a 2020 Outlander PHEV, typical consumption is ~2.1 L/100km (combined, WLTP) when regularly charged, or ~6.8 L/100km if run solely on petrol. Real-world electric range is 35–50 km depending on temperature and driving style. It meets Euro 6 standards with EN 228 fuel and proper charging discipline.
Yes. The 2.0L petrol engine (4B12 derivative) is an interference engine. However, it uses a chain-driven valvetrain with no scheduled replacement interval. Failure is extremely rare if oil is maintained properly. The electric motors eliminate the need for a starter, reducing mechanical stress.
Mitsubishi specifies API SN/ILSAC GF-5 grade petrol oil in SAE 0W‑20 viscosity. Use a high-quality full-synthetic blend and change every 15,000 km or 12 months. Correct oil is essential for engine longevity, especially to prevent dilution in short-trip driving scenarios.
