Fernando Alonso looks set to take on the "formidable challenge" of contesting the famous off-road Dakar Rally.
The Spaniard, who quit F1 at the end of last year, is this week testing a Toyota Hilux in South Africa.
"Fernando is now at a point in his life when he is open to any challenge," said rallying legend and Dakar regular Carlos Sainz, the father of the McLaren driver.
"And Dakar is a formidable challenge," Sainz told Cadena Ser radio.
If Alonso does take the bold step to Dakar, it will be with Toyota, for whom he also contests Le Mans in the LMP1 category.
"If Fernando comes, we could do a great job for him," Toyota's Dakar boss Glyn Hall told the Spanish daily Marca.
"It would be good for Toyota, good for our sport, good for the whole field. And Alonso would enjoy the challenge.
"Dakar is an incredibly difficult competition, but we know from formula one what a big fighter Fernando is," he added.
