Seven other people - including children - were injured when two lorries, a box van, a Nissan car and Mini crashed near Kemsing on Wednesday, April 16.
Two occupants of the Mini car - a man and seven-year-old boy - remain in hospital.
In a previous statement police said the group travelling in the Nissan were a family of four. The fourth passenger is believed to have survived, but it is not known if it is the girls' mother. The father's name has yet to be released.
Inquests into the deaths of the Akande sisters have now been opened and adjourned.
The pair were students and born in Créteil, a suburb of Paris. They lived with their family in Sarcelles, a northern suburb of Paris.
The inquest has been adjourned until Wednesday, July 23.
The Nissan driver died in a London hospital overnight, police said.
Insp Martin Stevens, of the serious collision investigation unit, said: "It is with great sadness that we report that the man died overnight in hospital.
"If anyone saw anything of the collision, or the vehicles involved prior to the collision occurring, and who has not yet contacted police we ask that they contact the Serious Collision Investigation Unit urgently on 01622 798538."
A 45-year-old lorry driver arrested after the crash has been released on bail until Friday, August 15, pending further inquiries.
