MG HS review - MPG, CO2 and running costs

The HS offers below average day-to-day running costs, although the more expensive plug-in hybrid model brings better efficiency

Possibly the most important priority for family motoring is keeping an eye firmly on running costs. Despite the car being a fairly large SUV MG has wisely chosen to steer away from offering the HS with all-wheel-drive or the option of adding huge alloy wheels - both of which adversely affect fuel consumption and bring higher CO2 emissions.

All HS models feature a stop-start function which helps with overall efficiency, while a tyre-pressure monitoring system and adaptive cruise control are useful additions.

What can’t be disguised, however, is that a basic turbocharged petrol engine powering a 1.5 tonne SUV is not going to return the best economy figures, compared to rivals that are equipped with smart new hybrid systems or fuel-saving cylinder deactivation tech.

The HS petrol model struggles here, delivering a best of 37.9mpg when paired with the six-speed manual gearbox, while the seven-speed auto only manages 36.6mpg on the combined cycle. High CO2 emissions starting from 168g/km won’t appeal to company car drivers, either, as the HS will attract a top 37% BiK rate.

Starting from almost £30,000, the HS plug-in hybrid gives away the standard model’s keen price point, but offers savings elsewhere. If you keep the 16.6kWh battery topped up you’ll benefit from the 32 miles of pure electric drive, while MG claims overall economy is as much as 155.8mpg. 

With increased trends towards working from home and shorter commuting distances, this figure may well be achievable in real-world conditions. A CO2 figure of 43g/km puts the HS plug-in hybrid model in the 11% BiK tax bracket.

Insurance

Insurance premiums shouldn’t be too expensive for the MG HS, as the petrol models sit in groups 16-18, which is about on par with rivals.

The plug-in hybrid model is in group 27-28, depending on specification, which is a little high in comparison to the Ford Kuga PHEV starting from group 21.

Depreciation

MG’s pricing strategy, combined with good levels of standard equipment, means the HS keeps its value well. Industry data suggests that after three-years and 36,000-miles of ownership, the mid-size SUV should retain around 47-49% of its original list price. These figures are just short of the Skoda Karoq and Ford Kuga, but similar to the Peugeot 3008.
