Mercedes boss Toto Wolff admits there will be teething problems during pre-season testing this year, but he has dismissed suggestions of a possible "bloodbath".
With new regulations coming into effect at the start of the 2014 campaign, teams, drivers, engineers and just about everyone else will have plenty to learn during testing.
The first winter test gets underway at Jerez, Spain, on January 28 and many believe quite a few teams will struggle on the opening few days as they come to grips with the rules.
However, Wolff feels talk that a lot of cars will break down is over the top.
"I don't think that it is going to be a bloodbath with cars not being on track and breaking down," he told Autosport. "But it is not going to be the usual testing, when you have an evolution of technical regulations and we are going to do 100 laps per day.
"It is probably going to be something in the middle. But this is part of a new development that you need to run to find out what the problems are. This is why we are going testing."
Lotus have already decided to skip the first test as they look to spend more time working on their new car in the factory and they have suggested several other teams could follow.
Wolff, though, says everyone will eventually come to grips with the new regulations.
"It is just a huge challenge with competition among the engineers - and this is an essential part of F1," he said.
"F1 has always been successful and has become the number one motorsport brand because it is about the innovation and competition among racing drivers and also the teams. Competition also comes with innovation.
"What we are getting next year is just 'wow'! One third more fuel efficiency and trying to maintain the level of performance, plus trying to fit all of that under the skin of a racing car.
"Cooling is an issue. Managing fuel efficiency is going to be key and at the same time having less aerodynamic downforce. Wow! It is good."
