What are the running costs?

  • Hybrid helps fuel efficiency 
  • No diesel option 
  • Real-world figures short of official WLTP

Hybrid power units have become increasingly popular in the last few years over their ability to cut down on running costs through improved fuel efficiency. Though the battery in the ZS isn’t very big, it provides enough electrical power to support the 1.5-litre petrol engine in moments when fuel consumption would otherwise be high, like when setting off. 

According to official WLTP figures, the ZS has a combined fuel efficiency figure of 55.4mpg. We could only achieve around 43mpg, which is far off the quoted number but still not bad for a car of this size.  

Servicing and warranty 

The ZS is offered with a seven-year or 80,000-mile warranty as standard – whichever comes first. This is a substantial degree of cover from a brand relaunch that still seems to be in its infancy, especially as some recent MG models have proven to be unreliable in recent years. 

Bespoke service plans are available from MG to help spread the cost of maintaining your car. Simply input your car’s registration and mileage with your expected yearly mileage and MG will calculate a plan for you.

A four-year service plan for a new ZS in Trophy spec would cost £2,082 with varying monthly premiums over the 48 month period, though shorter or longer time frames can be specified.

Reliability 

MG’s have had mixed reliability reports in recent years, but the 2024 car’s long warranty would suggest confidence from the brand in its product. The car felt robust during our test, without any flimsy parts that appeared easily breakable. The last model faced no recalls but we’ll report back here should any be announced.
