I checked and it requires workshop level 50 and vehicle level 60.
Thank you for reporting. It is worth at least 60 Zombie cookies.
I have just pushed an update to fix that. The progression.xml had a reference to craftingVehicles and it has been changed to craftingWorkstations for the unlock. And from level 60 to 50 to match the Chemistry Workstation. It was an oversight due to copy/paste from another reference.
To manually update, simply changing those to craftingWorkstations and 50,100 will be appropriate.
