The driver reacted quickly to pull the flaming car to the side of the road.
It happened M1 Southbound, J22 - J21A near Markfield.
Two crews from Coalville and Southern fire stations were in attendance after receiving 'numerous calls' about a car on fire.
The Mini was well alight when the teams arrived and was destroyed by the blaze.

The cause of the fire is believed to be a fuel leak which caused petrol to ignite on the hot engine.
Nobody was hurt but 2 lanes of the Southbound carriage way of the M1 were closed.
