Vettel calls Verstappen's signing 'borderline' in terms of age

Aug.27 (GMM) Max Verstappen made his debut in a Formula One car on Tuesday.

The well-connected Dutch newspaper De Telegraaf claims Red Bull, having newly signed the 16-year-old son of former F1 driver Jos Verstappen, has targeted October's Japanese Grand Prix as a potential first official outing for Max in 2014.

That is despite Toro Rosso chief Franz Tost saying at Spa that Verstappen's first Friday practice outings will only be in "Austin, Sao Paulo and Abu Dhabi".

But Red Bull may now be speeding up the teenager's already-accelerated F1 programme even more.

"Max is in England for a brief introduction," Max's father Jos is quoted as saying.

He is referring to an outing for Verstappen at Rockingham, at the wheel Red Bull's title-winning 2011 car, in Toro Rosso livery.

It is a shakedown ahead of a forthcoming demonstration event in Rotterdam.

"It (the Rockingham debut) is not a test," Verstappen's father said.

There is some sort of limit and Max is very young

"Today (Tuesday) he is driving back and forth on the straight to get used to a Formula One car."

Red Bull's Dr Helmut Marko confirmed: "Everything went well. Max did everything right, but I expected nothing else.

"When you talk to Max, you realise quickly that he is a confident young man who knows exactly what he is doing," he told Bild.

Vettel isn't completely convinced

But even Red Bull's very own Sebastian Vettel, who made his F1 debut as a teenager, has described Verstappen's age and experience as "borderline".

"There is some sort of limit and Max is very young," the German said on a visit to Sochi this week to try the new Russian Grand Prix layout.

"I guess he should go to school, but he is not going to have much time for that next year!

"He already has a lot of racing experience, and his talent is obvious," continued Vettel. "So why shouldn't he be in Formula One?"
