Frequently asked questions
Which Mg HS engine is the most reliable?
1.5 T DCT / 2.0 T (MG HS) — History-Dependent verdict. The current HS is sold as a 1.5 turbo with a 7-speed dual-clutch (15S4C, about 162 hp) or a 2.0 turbo with a torque-converter automatic (20L4E). This row carries both because the catalog lists them together; they are not the same gearbox. The MG EHS plug-in — a flat spot around 45 mph, a 6-speed DCT paired with a 4-speed EV drive — is a different car, and those threads must not be pasted onto this petrol HS. Owner forums read for this pass (MGEVs and the usual UK groups) did not produce a repeatable European failure of the 1.5T engine or of its dual-clutch: no mileage, no part, no code. Content-farm pages that quote clutch-pack replacement intervals were not used. What is repeatable on the MG4 and the ZS Hybrid+, and only there, is a 12V that flattens and software that misbehaves. Test those on an HS. Do not pretend they are a measured HS fault. Prefer the 2.0 automatic if the driving is queues, because a dual-clutch is the unproven part of the 1.5 car, not because a forum has already condemned it. A car with no stamps is the gamble. A car with stamps and a smooth queue test is not a known write-off.
