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) system for enhanced traction.
Fitted exclusively to the Outlander PHEV (GA/GG), the S-AWC Hybrid was designed to balance zero-emission capability with all-terrain versatility. Emissions compliance was achieved through precise engine stop/start control, electric-only mode, and a three-way catalytic converter, allowing Euro 6 compliance across all production years.
One documented concern is premature degradation of the high-voltage lithium-ion traction battery pack due to thermal stress in hot climates or frequent DC fast charging. This issue, referenced in Mitsubishi Technical Service Bulletin TSB-HV-2019-05, can reduce all-electric range and trigger hybrid system faults. From 2020 onward, Mitsubishi revised the battery cooling ducting and updated the battery management system (BMS) calibration to improve thermal resilience.
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 S-AWC Hybrid enables up to 54 km (WLTP) of all-electric range, ideal for urban commuting, but requires adherence to 15,000 km oil change intervals using API SN/ILSAC GF-5 0W-20 oil for the petrol engine. Frequent DC fast charging or operation in ambient temperatures above 40°C accelerates traction battery degradation—avoid where possible. Post-2020 models feature improved battery cooling ducting (P/N MD776655) per TSB-HV-2019-05 and should be prioritized for hot-climate use. Use only EN 228-compliant fuel and ensure 12V auxiliary battery health to prevent hybrid system immobilization.
Oil Specs: Requires API SN/ILSAC GF-5 (0W-20) specification (Mitsubishi Owner’s Manual 2020). ACEA A5/B5 acceptable if GF-5 unavailable.
Emissions: Euro 6 certification applies to all 2013–2023 models (VCA Type Approval #VCA/EMS/5923). No market-specific deviations.
Power Ratings: Measured under ISO 1585 and IEC 62660 standards for hybrid systems (Mitsubishi PT-2022).

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.
Locate the powertrain code on the left A-pillar VIN plate and hybrid system label under the bonnet (Mitsubishi TIS HV-SAWC-C). The 7th VIN digit is 'H' for hybrid variants. Visual identification: blue trim on front/rear motor housings, orange high-voltage cables, and 'PHEV' badging. Critical differentiation from conventional 4B12: S-AWC Hybrid uses no timing belt, has no starter motor, and features dual inverters. Pre-2020 battery packs use P/N MD665544; post-2020 use MD776655 with improved thermal ducting per TSB-HV-2019-05.
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.
