Toto Wolff suggested that Ferrari may have shown their hands in terms of strategy for the Bahrain Grand Prix after utilising an "unconventional" approach to Friday practice in Sakhir. Sebastian Vettel and Charles Leclerc were dominant in both sessions, topping both by more than half a second from the Silver Arrows.
Leclerc and Vettel topped a session apiece, with Vettel in P1 during FP2 – the only session run in night-time conditions similar to the race and qualifying.
Although Mercedes' advantage from Australia melted away in the desert, Wolff said it was little surprise.
"We're quite happy," Wolff told Sky Sports. "You can see enormous straight-line power from the Ferrari on the straight, it's where they're making all the gains.
"It's definitely a different Ferrari than we've seen in Melbourne.
"I don't know how there operating it [the car] but in terms of pure pace, definitely more Barcelona [Ferrari's strong pre-season form] than Melbourne."
