Porsche 911 (992.2) – MPG and running costs

Figures for the standard Carrera sit at 28mpg on the WLTP cycle, with the Carrera S capable of a combined 27.4mpg. The T, meanwhile achieves a marginally worse 26.9mpg, presumably because of its manual gearbox. 

Thanks to its hybrid system, the GTS achieves similar results despite being significantly more powerful and a little heavier than other Carreras. And from our experience, the claimed figures are well within reach – and sometimes surpassed – on a relaxed cruise. 

Porsche was rated as 2024’s top sports car brand in terms of overall customer satisfaction in the Driver Power Survey, run by our sister site Auto Express. There also haven’t been any stories of nightmare powertrain faults (early adopters of the 991.1 GT3 know what we’re talking about), but some electrical gremlins have been noted from owners we've spoken to. 

It's also worth noting Porsches are generally expensive to both buy and run. Aside from fuel, consumables such as tyres and brakes (particularly carbon ceramics) are expensive to replace, while general servicing and maintenance is also at the high end.
