TCC’s Bottom Line

The 2018 Porsche 718 range adds an impressive GTS variant to an already outstanding lineup.

The 2018 Porsche 911 is a superlative sports car that has defied its age. It’s a classic, but performs better than nearly any newcomer to its arena.

TCC Likes

Impressive new GTS version
Great engines
Impeccable interiors in all models

Breathtaking performance

TCC Dislikes

Room for two and not much else
Gets expensive in a hurry
Flat-6 sound is gone now

Not affordable for many
Everything is an option
“Purist” Porsches are exorbitantly expensive
