One appliance from Newport Fire Station was called to Staplers Road shortly after 10:35 after a fire developed under the bonnet of a Silver Peugeot 307.
The occupants of the vehicle, a couple in their 40s, realised there was a problem and pulled into the crown offices at Broadlands House, where security guards used fire extinguishers to tackle the blaze before the arrival of the Isle of Wight Fire and Rescue Service.
Island Echo understand the small fire was caused by an electrical fault in the dashboard.
It follows a vehicle fire yesterday in Sandown that destroyed the front of a Land Rover Discovery and a fire in Shanklin on Wednesday that destroyed a Vauxhall Zafira.
