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

However, the simple fact is the basic turbocharged petrol engine powering this 1.5-tonne SUV is not going to return the best economy figures, especially compared to rivals that are equipped as standard with hybrid powertrains or fuel-saving cylinder-deactivation tech.

The HS petrol struggles here, delivering 37.9mpg at best when paired with the six-speed manual gearbox, while the seven-speed auto manages only 36.6mpg on the WLTP combined cycle. High CO2 emissions starting from 168g/km won’t appeal to company car drivers, either, because the HS attracts a top 37 per cent Benefit-in-Kind (BiK) rate.

Starting from a smidge over £31,000, the HS plug-in hybrid sacrifices the standard model’s attractive price point, but offers savings elsewhere. As well as 32-mile electric driving range, MG claims the HS PHEV model can return up to 155.8mpg. A CO2 figure of 43g/km also puts the plug-in HS in the 12 per cent BiK tax bracket for company car drivers.

Electric range, battery and charging

The MG HS Plug-in Hybrid uses a single electric motor that draws power from a 16.6kWh battery. MG claims the set-up allows for up to 32 miles of pure-electric driving, or 44 miles if you’re just driving in town, as well as the improved fuel economy and emissions. Like most plug-in hybrids, the plug-in MG HS doesn’t have any rapid-charging capabilities. Fully recharging the 16.6kWh battery will take four-and-a-half hours using a 7kW home wallbox, so overnight top-ups will be a doddle.

Insurance

Insurance premiums for the MG HS will be much higher than they were just a few years ago. The petrol model previously sat in insurance groups 16-18, but the updated versions now land in groups 21-22, which is higher than more expensive rivals such as the Hyundai Tucson and Kia Sportage.

Meanwhile the plug-in hybrid HS sits in group 27-28, depending on specification, which again is higher than many of its rivals from Ford, Hyundai and Kia.

Depreciation

MG’s pricing strategy, combined with good levels of standard equipment, means the HS keeps its value well. Our latest industry data suggests that after three years and 36,000 miles of ownership, the HS should retain around 54 per cent of its original list price.
