McLaren grabbed the headlines with the fastest time in first practice at Turkey but there’s no missing the potential of Red Bull either.

The typical Friday pattern of little action early in the session was exaggerated as the Istanbul Park circuit sees little running outside of F1 weekends and so was particularly dirty.

That led most drivers to venture out even later than usual which is clear to see from the interactive chart above.

Lewis Hamilton put the best lap in on the fifth lap of a six-lap stint, impressively almost a second quicker than his team mate.

McLaren have tended to look good on Fridays this year, particularly as they’re chasing better performance in qualifying. This is the seventh time they’ve topped a Friday practice session this year.

The fastest Red Bull was Sebastian Vettel’s in fifth place, but look at when he set his best time for a clue to the RB6’s real potential here.

He set his fastest time on tyres that were 25 laps old (teams tend to use just one set of tyres in FP1). His sector two time, which includes the fast turn eight, was almost a match for Hamilton’s.

There was some encouragement for Force India with their trial of a new F-duct in practice. Vitantonio Liuzzi was the second fastest driver through the speed trap at 311.5kph.
