The aerodynamic changes have been a key focus in the development of the W12, but some of the parts on our new car are identical to the W11 owing to the new carryover rules. In some ways, this has lessened the peak of work required for the new car, but it’s also produced its own new challenges and difficulties.
“What’s carried over will look different from team to team, because the rules didn’t require you to carry over the same things,” explained James Allison. “The rules freeze a large chunk of the car, but then give each team two tokens to spend on changing their car. Along with the tokens comes a shopping list showing how many tokens are required for each change. How teams decided what to use their tokens on was entirely up to them.
“In addition, there are some parts of the car that you can change token-free, for example the Power Unit, the cooling systems, the suspension and of course all of the aerodynamic surfaces. We have spent our tokens, but we won’t reveal how we used them just yet. That’ll become clear in good time. Once the racing gets underway, pretty much everything under the skin of the car must then be frozen for the entire year. With the specific permission of the FIA, you can make changes for reliability or cost saving, but if part of your car isn’t performing well, then you are stuck with it for the whole season.”
