Black smoke billowed along the road after the blaze broke out in a blue Audi which was parked on a verge close to St Ouen’s Pond at about 1 pm on Tuesday.
An appliance with five firefighters was called from St Helier to deal with the blaze.
Toby Aubert, crew commander from the Jersey Fire and Rescue service’s Blue Watch, said the driver had pulled over after being notified by a motorist travelling behind that there was smoke coming from the rear of the vehicle.
He added: ‘It didn’t take us too long to get there but by that time the whole car was pretty much involved in fire.
‘When we extinguished the fire there was a lot of damage generally and more so on the driver’s side.
The wheels on the driver’s side were completely burnt out. They were alloy wheels, so they were burning at quite a high temperature.
‘The engine bay was pretty much burnt out. The explosion was the fuel tank – the fuel tank disintegrated.’
Nobody was injured during the incident and Mr Aubert said that it was not known why the fire broke out.
