Supermen with super powers?


A lot of myths have built up about what makes a driver quick. Surprisingly, superhuman eyesight and reflexes don’t seem to be a major factor. When tested, Michael Schumacher’s reflexes were decidedly average, for example. What makes a driver quick seems more to do with how the driver feels the behaviour of the car through the seat of his pants and his hands, and how soon and subtly he is able to perceive directional change through his inner ear.
This is where natural ability takes a driver places that data-logging and telemetry never can. Schumacher’s telemetry reveals entry speeds that team mates of the past have tried to simply copy – only to find themselves flying off the road. Only the natural feel and balance of a truly great driver can keep the car on the absolute knife-edge from the beginning of the corner to the end. This is where this most high

Cutting corners during qualifications


Braking for corners, and taking the corners, are where the skill is involved. Anyone can press their throttle foot to the floor and go quickly down the straights. How corners are taken is what separates the champion from the no-hoper.
Putting together the ultimate qualifying lap is an incredible balancing act for a driver. He must use his judgment and “feel” to find the latest possible braking point for each corner, the highest possible entry speed, and the earliest possible application of full throttle. Setting the car up during the practices is all about helping him achieve this. Different drivers have different styles and techniques and they need to set up the car in a way that best suits their individual requirements. Think of a corner as having three separate phases – entry (the approach to the corner), apex (the corner’s sharpest angle), and exit (the end of the corner). At this level of racing all the drivers will be on the correct line and travelling at about the same speed as they go into and through a corner. Finding an advantage is all about the tiniest of margins, and some drivers find theirs from their entry into a corner, others from their exit.
One tends to compromise the other – that is, going fast into a corner negatively impacts how quickly you can make it out the corner, and vice versa –so finding the ultimate trade-off is the key. A driver who can take more entry speed into a corner – who can get the car on the very limit right from the moment he begins braking – and then not be more than proportionally penalised on the exit, will be quick. But he needs to be able to do this on every corner for a decent qualifying lap.
Some drivers can deal with certain handling characteristics better than others. A car that oversteers (at the limit, the rear end breaks away first) can make some drivers very tentative. But while the opposite characteristic of understeer (where the front end loses grip before the rear) brings more stability and allows such drivers more confidence to push to the limit, it is usually slower. A driver relaxed with a measure of oversteer can usually get the car turned into the corner more efficiently than one who relies on the stability of understeer.

Getting pole is king


Being fastest in Saturday qualifying earns a driver pole position on the starting grid. This means he starts from the very front. Because overtaking is very difficult in a modern Formula One car, pole position carries an enormous advantage.
The tighter the track, the bigger this advantage tends to be. At tracks such as Monte Carlo or the Hungaroring, overtaking is close to impossible if the driver ahead doesn’t make a mistake. A driver getting pole position at either of these tracks may be considered to have the race half-won already.
In 2002, Michelin brought some super-soft compound qualifying tyres to Monte Carlo to enable its drivers to monopolise the front row of the grid. These tyres performed poorly in the race, as the soft compound led to rapid deterioration – but it didn’t matter. With track positioning all-important at Monte Carlo, Michelin-shod David Coulthard was able to keep Bridgestone user Michael Schumacher behind him throughout the race, even though Schumacher demonstrated that he could go at least 1 second per lap faster. Had he been able to lead from the start, Schumacher could conceivably have won by almost a lap. As it was, his qualifying position had consigned him to runner-up.
Not all tracks have such a lack of overtaking opportunities. At places such as Interlagos in Brazil or Hockenheim in Germany, you may see teams less concerned about pole position, especially if it means compromising their race strategies to achieve it.

Saturday qualifying: Improvisation


The rules dictate that no fuel can be added to the cars between the end of Saturday qualifying and the beginning of the race on Sunday. Furthermore, no changes can be made in the set-up of the cars during this period either. The direct result of these regulations is that the drivers must do their one qualifying lap on Saturday with enough fuel on board to get them to their first pit stop in the race on Sunday.
Driving a heavily-laden car on the limit without any build-up laps is an extremely difficult thing to do and perhaps represents the biggest challenge facing a driver all weekend.
When a driver spins or leaves the track during qualifying, that’s it. He gets no second chance. He does have the option, however, of continuing the lap (assuming the car’s still driveable) or aborting it. Aborting the lap can save him around a lap’s worth of fuel – which could be critical on race day. He will start from the back of the field then – but it’s likely that he would have done anyway had he spun.

Friday qualifying: No compromise


The results of Friday qualifying determine the order the cars take to the track on Saturday. The fastest car on Friday is the last car out on Saturday –theoretically the best slot. The results of Saturday qualifying determine the starting order of the race.
For Friday qualifying, the driver and his engineers don’t need to concern themselves with anything other than how to get the car around the track on its one flying lap as fast as possible. The car need have only enough fuel on board to get it through an out-lap, the flying lap, and an in-lap. Typically, cars will carry less than 10kg of fuel – compared to as much as 70kg during Saturday qualifying when there also needs to be enough fuel on board to enable the car to do its first race stint on Sunday. The difference between 10kg and 70kg of fuel can be as much as 1.8s per lap at some tracks. In addition to the lower weight, the cars are set up for ultimate speed over one lap, with no compromise for tyre wear or raceablity. For these reasons, on Friday qualifying, you will probably see the cars go faster than at any other stage of the weekend. A spin or a non-completion of a lap on Friday means that you will be at the back of the timesheets and therefore the first one to take to the track for Saturday qualifying – theoretically the slowest slot because the track will be at its dirtiest. Tyres of other cars will clear the dust and build up a layer of rubber on the track surface, making the track faster as the session goes on.

Debriefs and why the drivers disappear for hours


The engineers and drivers have an awful lot to discuss amongst themselves after the practice sessions have finished. This is why the drivers aren’t generally seen around the paddocks and garages for hours afterwards. Instead, they’re huddled together in the team motorhomes analysing the meaning of all the data thrown up by practice.
During these debriefs, the team can look in more detail at all the electronic data logging information and compare it with lap times and the driver’s subjective feelings. The pros and cons of one set-up over another, one tyre choice over another, one strategy over another can be discussed indefinitely. The more trouble a team is in, the longer the debriefs tend to take. Engineers value the debriefs immensely because it’s their best chance of bringing all the information together, at a time when it is still fresh in everyone’s minds. Not all drivers share the enthusiasm of the engineers, though. Some find debriefing sessions a little dull, especially coming immediately after the adrenaline-filled rush of driving a Formula One car at the limit. The very top drivers, however, look on these sessions as opportunities to extract the maximum out of their own performance and they give the appropriate time and effort.

What you may notice during F1 practice


When you watch Formula One drivers practice, keep a couple of things in mind.
First, being fastest isn’t everything. Although practice times are issued after each session, these times aren’t necessarily a definitive indicator of what shape every car is in. All teams work through their programmes in different ways and with different aims in mind. It’s often not until the qualifying sessions or the race that you see the true picture unfold as everyone tries to put together their best combination of factors. Treat the practice times as only a very loose indicator of competitiveness.
Second, some people get extra sessions. If you get to the track very early on Friday morning – well before the first official practice session – you’ll see some teams lapping the track while others never venture out and you may wonder why everyone isn’t out trying to beat the band. As a way of helping smaller teams cut costs, the FIA, the Formula One governing body, introduced a policy at the beginning of 2003 stating that a team could opt for one of the following:
  • To have unlimited test days.
  • To test up to a maximum of 20 car days (10 days for two cars or 20 days for one car) and be allowed to test for two hours on the Friday morning of each Grand Prix meeting.
The latter option is the cheaper one, but it has other advantages as well. It gives the teams a head-start in choosing the ideal tyre, in establishing fuel consumption figures, and in coming up with a good set-up. In terms of the work dedicated to the race weekend, by the time practice begins, they’re already one step ahead of those teams who can’t do the Friday test because they’ve opted for an unlimited number of test days outside of the Grand Prix weekends. The benefit of unlimited testing is that the total number of hours available for testing new developments and innovations is far greater. This particularly benefits the bigger teams who have more of such things to test than their smaller rivals.
