A koala called Timberwolf has survived an 88km freeway ride clinging to the bottom of car.

Timberwolf the koala is lucky to be alive after surviving a terrifying 88km ride down a busy freeway clinging to the bottom of a car.

The four-year-old male, who survived with nothing more than a torn nail, was struck by the vehicle near Maryborough in Queensland last week.

The Australia Zoo wildlife hospital said it latched onto the bottom of the car as it sped away, with the family inside not knowing they had a marsupial on board.

It was only when they stopped in Gympie after a high-speed freeway drive that they noticed it, and called the hospital for help.

Australia Zoo vet Claude Lacasse said it was amazing the koala, named Timberwolf by the rescuers who brought him in, was in such great health.

“It is absolutely amazing that he has such minor injuries and he survived,” Lacasse said.

“It is a truly remarkable story, he is a very lucky koala.”

Timberwolf was given pain killers for the torn nail and is recovering in a tree at the zoo north of Brisbane as vets work out exactly where he grabbed hold of the car so they can return him to the wild.
