We get the base GP5 in Singapore.
Everything is similar to Japan's top spec S-Sensing except without the electronic gizmo's, HID's and rear disk.
Driving wise, its way ahead of the RS which uses a CVT. The GP5 has a 7 speed dual clutch. The base model has no paddle shift, but thats a small loss compared to RS which has a lower power rating and definately miles ahead of Toyota's boring but efficient CVT.
In Singapores heavy traffic, the best I got was 23.8km/l, with the worst at 19.9km/l ( because of my heavy footed enjoyment of the 7 speed).
I thought I share this since nobody had done so to enlighten me before my taking delivery of the GP5 3 weeks ago.
