Vettel out on his own again as rest are left to play catch-up

SEBASTIAN VETTEL is adamant he is not unbeatable despite his near-perfect start to the defence of his Formula One world title.

From four grands prix this season Vettel has scooped four poles, three victories and a second to give him 93 points from a potential maximum of 100.

The 23-year-old’s latest triumph in Turkey yesterday was untroubled as he led for 56 of the 58 laps around the Istanbul Park circuit in a Red Bull that appears virtually untouchable.
