How much will it cost to run?

  • Two petrols to choose from
  • Poor fuel economy lets the side down
  • An electric version is also on offer

Fuel economy is a claimed average of 49.6mpg for the 106hp 1.5-litre petrol, dropping to just 44.9mpg if you opt for the 1.0-litre three-cylinder unit. 

With just two petrol models on offer the MG ZS was never going to offer up especially low emissions given its price. The 1.5-litre engine emits 129g/km of CO2, while the 1.0-litre automatic produces 144g/km.

That said, a zero local emissions all-electric model called the ZS EV is also available

Servicing and warranty

  • Cheap to service
  • Seven-year warranty suggests MG is confident
  • Owners report gearbox issues

The ZS should be pretty cheap to service providing you’re close enough to one of the 90 UK dealers. It speaks volumes that MG is willing to put its money where its mouth is and offer a seven-year/80,000-mile warranty (with no mileage cap in the first year). That means that should anything go wrong within that period, MG should cover the cost of the replacement parts and repair.

Saying that, the owners’ reviews for the MG ZS aren’t all positive, with multiple drivers complaining about noisy gearboxes.
