Ferrari boss Maurizio Arrivabene says his team has made huge strides forward with its engine in 2015 and is anticipating more improvements with its chassis next season.

Arrivabene has responded to comments from Niki Lauda who believes Ferrari has matched Mercedes in terms of power unit performance and fully expects a stronger challenge from the Italian squad in 2016.

The Ferrari team principal has heaped praise on his team behind the engine developments but isn't convinced by Lauda's words.

If Niki says so, I am quite suspicious!" Arrivabene joked. "Looking at the data, we are there because our engine department have done a great job and I want to take this occasion to thank them because, for us, the engine is the core of the car.

"I know we have other parts of the car where we have to work but this year it was not possible to make some huge changes. But we look forward for next year."

Without outlining any specific development areas for 2016, Arrivabene says Ferrari will aim to improve each area and teases positives to come for the new year.

"Of course, we can go next season with the same engine as this season, but this is what we are doing: we are looking to improve the car in every single part," he said. "The engine was a big improvement for this year, and next year we are working very hard on all the other parts of the car."
