Yes. Even though I own Xcent, but the engine is same 1.2L unit. So yes, to touch 100+, we need to cross ~3.5k mark and it surely does look stressed. But again, it will climb speeds till 140 before it runs out of breath. So I always stick to 90 km/h which put's rpm around 3k and increase speed when overtake. Else, you have to keep it in 110+ consistently and push till 140 to overtake! You have to learn to live with the limitation.
Slowly all limitations are presenting themselves and i am learning how to address them. I knew engine would be stressed out above 100 but its a different feeling altogether to witness that in your own car
