FORMULA ONE HAS undergone a radical overhaul of its technical regulations for the new season.
McLaren’s executive technical director James Key breaks down the “massive” changes in the rules, and how they’re likely to make races even closer and more dramatic in the battles for both the drivers’ and constructors’ championships.
Why have the regulations been revamped?
“The major reason is to improve the ability to race,” Key explains. “Formula One cars generate jet-fighter performance with huge amounts of downforce. But they rely on clean air to create that performance.
“When a driver follows another car and gets stuck in the so-called ‘dirty air’, the performance drop-off is massive, they cannot keep up, and that has made racing difficult.”
So, what’s changed?
“To remove that problem, Formula One, its governing body the FIA, and the teams, have come together to create a machine which is far less susceptible to the car in front.
“We have moved from 13-inch Pirelli wheels to 18-inch wheels. We have mud-guards over the front tyres, a simpler front wing design, and a new floor which has been raised a long way above the ground.
“The changes have been introduced to generate an air-flow which compliments the car behind, rather than hinder it. As far as aesthetics go, the most striking aspect are the new sidepods. The car is also heavier, up 50 kilograms from last year to almost 800 kilos.”
Does it work?
“The early signs seem to suggest that it is easier to follow. Hopefully it will also reduce the performance difference between the teams and create a tighter grid. The closer racing will be more fun for the drivers and the sport only benefits from that entertainment.”
How big a challenge has it been?
“From a technical perspective, it has been a huge challenge because it is a massive change. This is my 25th season in Formula One and it is certainly the biggest change I have seen during my time in the sport.
“We have had hefty changes in the past, but all of those were based around the same principles and you could adapt what you already knew. But this year, we have started with a clean sheet of paper, and that has never been the case before.”
And what about Mercedes’ new sidepods?
“Hats off to them for giving it a go. It is a brave decision to go for something so different which needs quite a lot of mechanical engineering to get it to work.
“You might also say it is just one of 10 different concepts. Mercedes’ tiny sidepods are on the other end of the scale to Ferrari’s, but I am sure they will both be competitive.
“Perhaps that suggests the sidepods will not be a major player. Mercedes have certainly gone the most extreme so it will be interesting to see how it pans out and if that was the right way to go.”
Has anyone stolen an advantage?
“This year, more than ever, it is really difficult to tell. Teams run different tyres, fuel, and engine modes – all of which significantly change how fast the car is – during testing and there is no point showing your hand. It seems to be reasonably close.
“One has to believe Mercedes and Red Bull will be strong. They have both been bold with their designs, which you might expect given their legacies of investment, success and the methodologies which have worked for them in the past. Ferrari do look strong and where we are in that mix? I don’t know.
“None of us can predict how the grid will shape up in Bahrain. We will only find out on Sunday.”
