Porsche 718 Boxster: what will it cost me to run?

The double-edged sword of turbocharging means these smaller engines make more power than their bulkier six-cylinder predecessors while still offering better running costs.

In manual cars, you can aim for 38.2mpg in the 718 Boxster and 34.9mpg in the S - up to 13% more efficient than before in official tests.

If you choose the PDK dual-clutch automatic gearbox, claimed economy is more impressive. The standard 718 Boxster achieves a claimed 40.9mpg, while the S returns up to 38.7mpg.

If you bought a Boxster for the frugal engines, then something’s gone amiss. If you enjoy driving it and taking advantage of the power and performance on offer, economy like this won’t be achievable, but on a steady run it’s easy to get above 30mpg.

Reliability

3 out of 5 3.0
  • Plush materials and solid build
  • High engineering standards
  • Not entirely without fault, though

Porsche 718 Boxster: will it be reliable?

Porsches are meticulously built and the standards of engineering are very high too. The average Porsche owner has high expectations from their car and few are ever disappointed by reliability. This is reflected in our owners' reviews, which at time of writing show one five-star review, and another with a one-star rating. A sample size of two isn't huge, but it's an indicator that all perhaps is not as it should be here.

And while it all looks and feels very well screwed together, the 718 hasn’t been without fault since it was launched.

There have been four recalls issued affecting the car and other Porsche models, so it’s worth checking any remedial work has been carried out if you’re buying a used example.
