Low figures relate to the least economical version; high to the most economical. Based on WLTP combined fuel economy for versions of this car made since September 2017 only, and typical current fuel or electricity costs.

Fuel economy

Petrol engines 37.2 - 44.8 mpg
  • Thirstier 2.0-litre engine still reasonably cheap to run
  • Smaller 1.5-litre car remains the most economical
  • Relatively low power output means reasonable insurance costs

The most economical Mazda MX-5 RF belongs to the 1.5-litre engine, with a claimed 44.8mpg. The 2.0-litre still manages to hover about 40mpg, with a figure of 40.9mpg, although the automatic gearbox sees this dip down to 37.2.mpg.

Mazda MX-5 RF SkyActive technology

Stop-start is standard on all engines, while fuel tank capacity is 45 litres, so you should see towards 400 miles between fill-ups.

Green credentials

If you’re looking to minimise your carbon footprint then the cheaper 1.5-litre MX-5 is the one to go for, emitting just 142g/km of CO2.

Emissions for the 2.0-litre manual rises up to 155g/km of CO2, although if you spec the automatic gearbox, this jumps up further to 171g/km.


  • Simple but well-engineered
  • No official recalls for MX-5
  • Hard-top roof worth keeping an eye on

The MX-5 RF’s reliability should be very similar to that of its soft-top sibling – a car that possesses very few major safety recalls or major faults.

However, there’s no denying that the RF is more complicated than the famously simple MX-5 soft top, with an electric folding hardtop roof and automatic gearbox option. Models with the latter fitted were subject to a recall in 2018 for a software update, as the automatic gearbox could unexpectedly downshift into a lower gear.

Make sure you treat both with care in order to get the best out of your MX-5 RF, regularly getting the vehicle serviced and not attempting to lower the roof in unsuitable conditions.

The Parkers’ Owners’ Reviews section suggests MX-5 customers are highly satisfied with their cars and rarely report any serious problems.
