Porsche has issued a recall of the latest incarnation of the 911 GT3 after two of the sports cars caught fire.
The company warned owners to stop driving their £100,000 vehicles, which were first launched in 1999, until their engines have been replaced. Deliveries of the model have been frozen after two incidents in Switzerland and Italy.
So far Porsche has delivered 785 of the new cars worldwide and 100 in the UK.
Loose bolts in a piston-connecting rod are thought to be behind the fires. In both reported cases, engine damage sparked the fire after oil spilled onto hot components. Neither of the fires led to any injuries.
