West Midlands Police are investigating a spate of carjackings which are believed to have involved the same gang in Solihull.
Video footage released by the police shows a woman who was knocked to the floor as her BMW X5 was taken from her drive.
The violent robbers, armed with a crowbar, have struck three times since the start of July.
Police are appealing for anyone with information to get in touch with them.
DC Amrit Nepaul, from Force CID in Solihull, said: “This was a terrifying situation for the victims to be faced with.
“These men were not afraid to use violence to get what they wanted. The victims were left in fear of what would happen to them.
“We’re following lines of enquiry but if you’ve heard anything, or know whose involved, we need you to contact us as soon as possible.”
Anyone with information is urged to contact West Midlands Police via Live Chat at www.west-midlands.police.uk, via 101, or via Crimestoppers anonymously on 0800 555111. Quote 20SH/164245E/20.
