Character

MCF 4.8 V8 TT

"Panamera Turbo/Turbo S. Last Porsche 4.8 V8. Twin-turbo. Timing chain. Oil consumption under track use. Replaced by 4.0 V8. Powerful and refined."

9A2 B4T (2.0/2.5)

"Porsche 2.0 and 2.5 turbo flat-four from the 9A2 engine family, used in the 718 Boxster and 718 Cayman (base, T, S and 2.5 GTS) from 2016. Not the IMS-era flat-six: no bore-scoring pattern is documented for this engine. Known faults are cooling-system items covered by Porsche bulletins and an early fuel-pipe recall. The sound divides opinion, the engine itself has a good record so far."
