The driver sped away, only to then crash into another vehicle in the 5700 block of N. Broad at Old York Road.
The 14-year-old driver and a 14-year-old passenger were found inside the stolen vehicle with multiple injuries.
Those teens, plus the 34-year-old man driving the other vehicle, are all hospitalized in critical condition. Police say they are expected to survive.
The teens are being held as prisoners, police say.
A police cruiser was damaged when it was struck by the stolen car at one point during the incident but no officers were injured.
