Mercedes doubled down on its failed 2022 concept in 2023, which left it unable to bridge the gap with the dominant Red Bull squad as it beat Ferrari to a distant second place in the constructors' standings.

Speaking to The Daily Telegraph, Wolff has shared positive preliminary reports from Mercedes simulator driver Anthony Davidson that the car feels much more together than its troubled predecessors, which proved unpredictable and hard to drive for Lewis Hamilton and George Russell.
"He was driving Melbourne [in the sim] and he said: 'The car feels like a car for the first time in two years'," Wolff said.
"Obviously, I would love this to correlate to the track but we've seen in the last two years that this was not always the case."
Wolff has previously likened Mercedes' challenge of being able to catch and beat Red Bull during the current regulations cycle, which runs for two more seasons, to scaling Mount Everest and "against the odds".
