Ford Mustang Convertible: is it expensive to run?

Considering the Mustang’s heft and performance, running costs are, at best, reasonable. A hybrid version is expected for the future but, for now, you’d have to be optimistic to run either of the two petrol engines on a tight budget.

The 2.3-litre Ecoboost claims to return 31.0mpg with the manual gearbox, dipping to 29.7mpg if you select the automatic.

The 5.0-litre V8 will be gulping fuel at a more considerable rate, returning 22.0mpg with the manual gearbox, or 22.5mpg if you choose the automatic.

Despite the slightly larger 61-litre fuel tank in the V8 – compared with 59-litres in the EcoBoost – this will still mean frequent visits to the petrol station.

While neither of these engines will be remembered for their fuel efficiency, our testing has found they at least come close to matching their official figures when driven gently over a long distance.

  • Look elsewhere if you seek low CO2 emissions
  • Tax costs won’t impress anyone either
  • Ecoboost best on emissions

Ford Mustang Convertible: is it eco friendly?

The Ford Mustang’s engine line-up won’t be winning awards for being particularly clean anytime soon. The 2.3-litre Ecoboost engine with the manual gearbox is the cleanest, emitting 200g/km of CO2, rising to 211g/km with the automatic gearbox.

Unsurprisingly, the larger 5.0-litre V8 will sit in a more expensive tax band, with CO2 emissions of 285g/km on the manual version. Curiously, if you choose the automatic gearbox, the V8 will emit fewer emissions, at 279g/km. Despite the marginal drop in emissions, it doesn’t result in a lower road tax band. 

  • First UK Mustang has limited issues so far
  • Tech and engines used elsewhere
  • Two recalls since 2016

Ford Mustang Convertible: is it reliable?

While Ford may not sit at the top of the table for solid build quality and reliable cars, the Ford Mustang Convertible has been subject to two recalls so far.

These were issued in 2016 and 2017 applying to the safety equipment in cars. One was to counter a potential fire risk in V8-engined cars while the later-dated recall corrected the driver’s side airbags.

These shouldn’t a concern when buying new but make sure Ford fixed the issue in the history of one should you buy used.

While the materials in the cabin may not age too well, the construction feels well-built enough to last.

While V8-engined Fords are relatively scarce in the UK, Ford has decades of experience in other markets, so expect few issues in that regard. While the 2.3-litre EcoBoost may have had a recall in the Focus RS, this detuned version in the Mustang has had no such problems so far.
