S3 Exige S V6 - Slow at the Ring?

[SarlechS]

Can anyone let me know why the Exige S is so slow at the ring when compared to a 981 Cayman GTS?

Exige S
Power - 345 BHP
Weight - 1130 KG
Time - 7:53

981 Cayman GTS
Power - 335 BHP
Weight - 1360KG
Time - 7:53

Now i know there's more to a cars performance than seeing how quick it laps the ring but i find its a good barometer for all round performance , when i was looking at the two cars i'm considering as my next car i was expecting the Exige S to be so much quicker than the 981 Cayman GTS, 230kg lighter, more power, it should be an easy win?

Does anyone know why the Exige struggles with the Ring? It may be something simple like Lotus don't send their cars to the ring and that time i found on the Exige is an amature time vs a Pro time from Porsche? I just found it interesting...

Keen to hear your thoughts!
