Dulcibella King-Hall notched up a top speed of 108mph in a BMW M3 to celebrate her upcoming 107th birthday.
Miss King-Hall, of Tunbridge Wells, declared: "It could have been faster", as she was helped back into her wheelchair after completing four laps as a passenger.
Asked why she loved the thrill of speed, she replied: "Why shouldn't I? Don't you like it? I like the feeling of the vehicle going vroom."
Born in Devon in 1902, Miss King-Hall has loved cars since she tested vehicles commandeered from civilian use during the Second World War.
Pulling into the pit stop after three laps, Miss King-Hall sped off for a final loop of the circuit watched by a crowd of awestruck well-wishers.
Driver, chief instructor Gary Palmer, 39, said: "I said: 'Shall we do another lap?' and she said 'yes'. It's incredible. We don't normally see people of that age on the track."
Lena Akers, social events coordinator at the Halliwell nursing home where she lives, organised a trip in a Porsche for Miss King-Hall's 100th birthday, then a drive in a Rolls-Royce when she turned 105.
She said she felt she had to "up the ante" this year, adding: "Cars are an abiding passion of Dulcibella's. Her love of speed has her constantly asking our minibus driver 'to go a little faster please'.
"If you have a lady who loves speed, I couldn't think of anywhere else better to come than Brands Hatch."
