It’s no secret that the new era of cars introduced for the 2017 Formula One season are tougher to handle out on track. But a lesser-known, if equally significant challenge is getting these mighty beasts off the line.
Gone are the clever engineering maps to help find a clutch position
New restrictions governing the influence of engineers over race starts is the latest move to reduce so-called ‘driver aids’. For 2017, there are new limits on clutch control, as well as the movement and location of the steering wheel paddles.
The target? To make the relationship between what the driver does with the clutch and the amount of torque that gets transferred through to the racetrack much more direct. Drivers still use a single clutch paddle. But, unlike previous years, clutch control is now a linear relationship. Gone are the clever engineering maps to help find a clutch position – that special sweet spot for the perfect getaway.
Previously, a driver only needed to drop the clutch in the wide zone – a launch map setting predetermined by an engineer – for a clean start. Now, they have to control the torque themselves with the steering wheel paddle, making it a very direct relationship between what the driver wants and what he gets.
To that effect, the rules have been tightened on teams using any kind of steering wheel reference to assist drivers with race starts. The movement of the clutch paddle is limited to 80mm and it is forbidden to set a position in the motion of the clutch paddle that feels different, or where the driver can hold it in a particular position to get a specific torque.
This has been achieved through the introduction of a significant exclusion zone around the paddle, meaning the driver can’t access anything else whilst using the clutch. Fundamentally, the driver operates the paddle by himself without any external reference.
The Silver Arrows have lost just one position in three races thus far
It’s now completely up to the driver to position his hand and feel the torque of the car as it accelerates. Those drivers who have a feel for modulating the torque to the rear wheels, keeping the wheel spin under control and accelerating smoothly will get better starts. Those who are a bit too aggressive will get wheel spin. It’s all down to the men at the wheel.
Given the extent of the challenge, it may therefore come as something of a surprise to see how little variability there has been between drivers and teams over the first three races of 2017. The biggest single loss off the grid so far this year has been by Sergio Pérez, who dropped three positions in the wet start in China – the weather adding another variable. In contrast, the two McLarens were quick off the line in Shanghai, both gaining three spots each.
The Silver Arrows have lost just one position in three races thus far – Lewis dropping behind Sebastian Vettel’s Ferrari in Bahrain under braking into Turn 1. In the same race, Pascal Wehrlein was shuffled down the pack on his first full race start of 2017, before battling his way back through the field to P11 by the flag.
So how has this been achieved? Simply put, a major contributor is that drivers are doing more practice than ever before. It’s the typical Formula One case study – present a set of world class athletes and the world’s very best engineers with a challenge and they’ll rise to it. Being the world’s quickest racing driver does not automatically equate to being able to pinpoint release a paddle to nail that perfect start. Practice makes perfect.
This brings with it some entirely different challenges
More so than ever in 2017, a driver’s start is a result of hard work over pure luck. Teams have reimagined starts into a science through systems, technology and practice. And the perfect start is a result of hard work and dedication from the drivers, continuously working with their engineers to perfect this procedure.
The outcome of a driver’s race can be determined by what they do in those first three seconds. They now have more control over this aspect of racing, so they’ve taken on more responsibility. And as the early data shows, they’re stepping up to the challenge – just as one would expect the world’s best to.
However, looking ahead to Sochi this weekend, the long run down into the braking zone at Turn 2 – the scene of last year’s opening lap accident – provides another new challenge. 501m covers the sprint from pole to Turn 1 in Bahrain; 458m in Shanghai and, for Melbourne, a relatively short 383m dash before sweeping into the first corner. Sochi on the other hand is a 1,029m stretch from pole to the Turn 2 apex.
This brings with it some entirely different challenges. Factor in the increased drag of the 2017 cars, for example, which will affect each car on the long run into the first braking zone. The man on pole will take a big hit to those following from the second row and further back, who can make use of the tow to take advantage of, or even negate the effect of, a poor start. With a run down into Turn 2 at twice the distance of Bahrain, the opening seconds of the Grand Prix may prove the most exciting and variable we have seen so far in 2017...
