"It's never going completely seamlessly or smoothly, as a matter of fact you're trying to push the boundaries and make the car as light as possible and eventually as quick as possible. We've had a good winter, I would say, no real drama. But there is always stress within the organisation at that time of year."
F1 never stops. It may be called the 'winter break' but at the factory, there's little time to pause and reflect. The focus is always on what's ahead. The development cycle of designing and creating F1 cars is relentless, but it's also a hugely rewarding time too, as things begin to properly take shape.
"The winter is intense", says Technical Director James Allison. "The planners have got thousands of lines of plans to deliver on, the design group have got to deliver several hundred new designs per day in order that they can be made.
"All of the test and development people and the people running the dynos have to stand ready as the pieces come in hot from the machines that made them to assemble them up and put them on all the in-house testing kit that allows us to be reasonably sure that everything is strong enough and has the right shape and will perform reliably."
