The build-up to the new season has officially begun with the first 2019 car launch date pencilled in.
Ferrari, who will be looking to finally overhaul Mercedes at the top of the Formula 1 tree, will be revealing their 2019 challenger on February 15.
That is just three days before the first pre-season test gets underway at the Circuit de Catalunya in Barcelona.
“The group led by Mattia Binotto has been working on next year’s single-seater for months now,” Arrivabene said at the Autosprint awards in Milan.
“The engines are already running on the test benches and there are parts of the car that are already in production.”
“The parts more related to the performance will arrive at the last moment.
“Even if the tension increases because the time is less and less. On February 15 we will present the car and everything must be ready for that day.”
Arrivabene said, though, that it is still too early at this stage to go into specific details about Ferrari’s new car.
“It is too early to give an overall picture of the car,” he added.
“Simulations are being done and we are working on the simulator, but the real test bench is only the track.
“That’s where you confront yourself, comparing the data you’ve collected during the winter period, and especially where you confront yourself with others.
“The technicians are working hard to complete the car. We have some information from the guys who work on the simulator, but it’s still too early to talk about performance.”
