Lewis Hamilton has conceded he is like a "broken record" in his push for Mercedes to change aerodynamic development direction in F1.
The Silver Arrows made strides with its major upgrade package at the Monaco Grand Prix, with the team since taking over second in the Constructors' standings.
Hamilton secured his first pole in 19 months at the Hungarian Grand Prix, pipping rival Max Verstappen by 0.003secs with a stunning lap.
But the seven-time World Champion was powerless to defend into Turn 1 as the current title holder surged clear, eventually finishing 33 seconds up the road from McLaren's Lando Norris as Hamilton fell to fourth.

A lot of work to do
Hamilton has been vocal about the shortcomings of the W14 and its predecessor last season given Mercedes' struggles, as the Brackley-based outfit bids to recover lost ground on the dominant Red Bull RB19.
The pace at the start of stints in the race was a far cry from the performance on display across one lap at the Hungaroring and asked why the car seems faster on low fuel, Hamilton told Sky Sports F1: "The car isn't much quicker [generally]. This weekend it was quicker.
"We generally have a bigger wing than some of the others, like the Red Bulls for example, but they seem to have more downforce from their floor.
"We have a lot of work to do. I'm like a broken record, I have just got to keep telling the guys that we need to go in that direction.
"I would love to see that either this year or at least on next year's car."
