Ferrari has faced problems with their windtunnel and have developed their 2013 challenger using Toyota's facility in Cologne.
"The development of the 2013 car began in the Cologne wind tunnel and is on-going," said Domenicali. "I certainly expect to see greater efficiency than last year because we will no longer need to carry out comparisons of data and correlation with the Maranello wind tunnel, which is currently being rebuilt and is due to be operational again after the summer break."
The Italian described 2013 as 'complex', courtesy of the rule changes arriving in 2014.
"We face a few changes on the technical front which will have a significant impact on all areas of the company, not just in terms of design, but also when it comes to the investment and infrastructure required to develop the new engine".
"Within the limits imposed by the regulations, we need to put every effort into reaching our objectives, while making the best use of the timescale in preparing for 2014. Our aim is clear, to win and the priority is still that of giving our drivers a car that will be competitive right from the very start."
