MG HS Owner’s Guide (2018–present)
The MG HS is two different cars under one name: the first generation (2018–2024, including the eHS plug-in) and the second generation launched July 2024 with petrol, full-hybrid and plug-in options. Before anything else: if you own a 2021–2022 first-generation HS plug-in, check the fire-risk recall below — 5,168 cars in Australia and the equivalent UK campaign.
Generations at a glance
| Generation | Years | Powertrains |
|---|---|---|
| HS (first generation) | 2018–2024 | 1.5T petrol (1,490 cc, MT/DCT); eHS PHEV from ~2021 |
| HS (second generation, AS33) | 2024–present | 1.5T petrol (125 kW), 1.5T Hybrid+ (HEV), 1.5T PHEV, 2.0T (170 kW, select markets) |
Generation history cross-verified: official MG documents × model-history records (unveiled Goodwood, July 2024; HEV added 2025).
Second-generation engines — official figures
| 1.5T (MT/DCT) | 1.5T EDU (HEV/PHEV) | 2.0T | |
|---|---|---|---|
| Displacement | 1,496 cc | 1,496 cc | 1,986 cc |
| Power / torque | 125 kW / 275 Nm | 105 kW / 230 Nm (engine alone) | 170 kW / 380 Nm |
| Compression | 10.5 | 13.5 (Miller-cycle high CR) | 11.5 |
| Fuel | RON 95+ (E5/E10 compatible) | ||
Hybrid drive motors (official): HEV traction motor up to 146 kW / 340 Nm; PHEV up to 154 kW / 340 Nm — the electric side, not the petrol engine, does the heavy lifting.
Cross-verified against two independent official manuals: MG HS Range Owner’s Manual (UK, 2025) × MG HS Hybrid Owner’s Manual (Middle East edition) — tables match line for line.
