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.
OEM-verified: read from the MG HS Range Owner’s Manual (UK, 2025) and the MG HS Owner’s Manual (Middle East edition). Both are published by MG, so where they agree they corroborate our reading rather than adding an independent check of it — which is why these figures carry the label our verification ladder gives an official primary document standing on its own, not the two-source rule.
