Ex-F1 driver Johnny Herbert reckons Ferrari's early advantage in Hungary comes from the SF-75 being a well-balanced machine.
Carlos Sainz and Charles Leclerc each topped one of Friday's two practice sessions, and Herbert said the Ferrari's handling characteristics made it an ideal vehicle to tackle the twisty Hungaroring circuit.
"That car just looks so balanced," Herbert told Sky Sports F1.
"That's exactly what you need around this circuit because that allows you to get pinpoint accuracy at the apex, and shoot the car out on the exit.
"[Ferrari] don't seem to have an issue where the car is slightly squirming around, which then overheats the tires.
"It just seems to be a very, very well-balanced car that gives you the lap time."

Herbert not ruling out Red Bull
While Ferrari seemingly drew first blood after Friday's running, Red Bull and Max Verstappen remained in close attendance throughout, and Herbert said the championship-leading squad could not be discounted.
"You're never going to rule out that Red Bull, because you always know when you're thrashing it and get it right on the very edge, that's where Max and sometimes [teammate] Sergio [Perez] get the very best out of it," said Herbert.
"They've (Ferrari) got a car that is working very, very well, but they're very aware that Red Bull are going to be very much on their heels on Saturday."
