Gasly scared engine gap will decide Sauber battle

Pierre Gasly worries that Toro Rosso won't have enough compared to Sauber as the two teams battle it out in the Constructors' Championship.

The Toro Rosso driver desribed the differences in engines as "huge".

Sauber use a Ferrari engine and the Frenchman believes that there is a massive gap in power between the two sides.

Toro Rosso are watching over their shoulders now, with Sauber right on their tail in the Constructors' Championship.

The latter finished towards the bottom last season, but with new ownership, the future of Sauber looks very bright.

"Sauber is really fast, so I think it will really, really difficult to keep them behind with the pace we have because they have a stronger package," Gasly told Autosport.

"In terms of chassis we are still ahead of them but in terms of engine and power unit package that they get from Ferrari they just make a huge difference with that.

"I expect them to score consistently in the points now, so it will be really difficult to keep them behind but we will try what we can."

Gasly got P4 and then P7 in Bahrain and Monaco, but lost a point at Silverstone following a penalty that he strongly disagreed with.

"We need to make sure that when there are opportunities like Bahrain and Monaco we are there to score points," Gasly said.

"In normal conditions at the moment we don't have the package and speed to fight there.

"Haas is really fast and Sauber is really fast with the Ferrari engine.

"We saw Force India is doing well and Renault has a really strong package between the chassis and the power unit."
