Fuel economy

Petrol engines 36.6 - 37.9 mpg
Plug-in hybrid petrol engines 155.8 mpg
  • Decent fuel economy
  • Reasonable BiK rates
  • Affordable tax

In standard petrol form, the fuel economy is reasonable, at 37.2mpg. For the manual, the CO2 output is 148g/km, while the auto is 157. VED in year one is £210 for a manual, £530 for an auto. BiK is 33% across the board.

The MG HS PHEV looks more promising - its WLTP combined fuel economy figure is 155.8mpg and the CO2 output is 43g/km. When plugged into a 7kW wallbox, the HS PHEV’s battery pack will fully charge in three hours.

Residual figures are looking stronger than previous MGs, and these will be further improved by the arrival of the more desirable PHEV.


MG's cars aren't exactly complicated by the standards of the class, and there are fewer items to go wrong. Though 'made in China' isn't exactly a buzzword for high quality, owners seem extremely satisfied with the quality of their MGs so far, and there's no reason that the HS shouldn't continue this. A well-liked - and rapidly growing - dealer network is also on hand should anything go wrong.

MG's clearly confident in the quality of its engineering as it gives its cars the joint-longest warranty in the business, with the seven-year period matching both Kia and SsangYong. The mileage limit's slightly lower than those manufacturers, though, at 80,000 miles.
