The brakes of the Mercedes car carrying industrialist Cyrus Mistry and three others were applied five seconds before it crashed, the luxury carmaker said in its interim report submitted to Palghar police, an official said.
The police official also said that a team of experts from Mercedes-Benz is scheduled to visit Mumbai on Monday from Hong Kong to inspect the car.
Meanwhile, the German auto maker said in a statement that it was co-operating with the authorities in the investigation of the car crash and will share the findings only with them as it respects customer privacy.
Mistry (54) and his friend Jahangir Pandole were killed on Sunday afternoon when their Mercedes car hit a road divider in the Palghar district.
Two other car occupants, Anahita Pandole (55), who was at the wheel, and her husband Darius Pandole (60) suffered injuries and were admitted to a private hospital in Mumbai.
The accident occurred on the Surya river bridge when they were on their way to Mumbai from Gujarat.
