Mercedes team boss Toto Wolff has demanded Mercedes get everything they can from their car and put in as much effort as possible to do so.
"After the Barcelona test, we felt that we were the challengers," Wolff said. "Whatever the Melbourne result says, our mindset hasn't changed since then.
"One race doesn't determine the pecking order for the rest of the season. We need to extract every bit of performance from our package and keep on working hard to improve the car over the weekend to be competitive."
Mercedes have every right to be optimistic ahead of the Bahrain Grand Prix having come out on top their in three of the past five years.
