There are "interesting developments" in the exhaust area however.
Jan.17 (GMM) Ferrari's new car will look similar to the 2012 model, team boss Stefano Domenicali has admitted.
Indeed, that will be the trend up and down the grid this season, as teams handle the complicated transition to the radical new V6 engine rules for 2014.
Ferrari, "it won't be very different from the 2012 car."
But La Gazzetta dello Sport quoted him as saying there are "interesting developments" in the exhaust area, while Ferrari is now pushing "the boundary of the regulations" harder than before.
2013, Domenicali admitted, will be arguably tougher than ever before.
"Since the budgets and manpower are limited by the rules," he is quoted by Tuttosport, "this is a very delicate task."
He is referring to the need to focus almost simultaneously this year on winning the 2013 world championship with a 2012-like set of rules, and preparing for the all-new turbo era.
"I'm also assuming that some teams in the summer of 2013 will abandon the development of their (2013) project or severely restrict it, if the title is out of reach.
"Since I assume that we will be fighting for the title, this is not a possibility for us," said Domenicali.
