Power output from the drivetrain is around 400kW ‘What could be very interesting to see is a challenge between conventionally powered rallycross cars and electric cars,’ Sakowicz says. ‘I think this would be something that people would love to see and it would also demonstrate the capabilities of an electric car and might also encourage the fans to accept electric cars more.’ Over-charging For easy access the batteries are located at the side of and behind the driver and can be changed in under 15 minutes.

A car peels off to take its Joker Lap, something each racecar must do once in every race, whether it’s a heat, semi final or the final. It’s Playing the Joker proved so successful that the WTCC’s now going to adopt the concept It’s not all flat-out, no-holds-barred racing in rallycross – there’s also the need for cool, strategic thinking to make the most of the Joker Lap. Racecar investigates

The Joker Lap essentially injects a short sprint race with all the drama and strategy of a pit stop, just in a much narrower time-frame

Therefore, the average sector and accumulated throughout these heats are then With such compressed races, there is no need cases. This is a clever way of adding an element the Joker Lap gains or loses time, you want Peugeot-Hansen. ‘This happened at Lydden lap times change with every lap, adding used to classify the drivers, with the top 12 for pit stops, of course, and safety cars are of strategy to the race, because there is no to complete it as efficiently as possible and Hill, for example, where the tyre stacks moved another element of complexity that has to making it through to the semi-finals.

you already know how the track changes with weather and temperature,’ explains Hansen. ‘You also need to consider the position of the entrance to the Joker Lap. At Lydden Hill, for example, the Joker Lap was before the first corner, so if you were on the outside of the grid and believed that nothing unexpected would happen, then it made sense to take the Joker on the first lap. Of course, things change and you can’t expect anything so you need to have a second strategy and quickly come up with new ideas. Who are you competing with? Who has been on the Joker? What is the gap to the driver who has already been on the Joker? As a spotter, you try and inform your drivers to keep them up to speed on whether they need to push more. The problem is, it’s never clear and you only have a few seconds to have a quick discussion with your other team spotter before you have to make a decision. It’s very stressful, but it’s a positive stress.’ Old jokes Hansen’s past experience as a driver offers a great advantage during these stressful situations, however, as he understands the feelings and emotions of the driver in the car. This means he can think in a way that is perhaps more relevant to the driver. This has clearly proved advantageous. The other spotter is also a previous driver and both have contributed to the successful Joker Lap strategy for Team Peugeot-Hansen. Making decisions in this high-pressured environment can lead to mistakes, where sometimes the drivers miss the Joker Lap entirely, as Reinis Nitiss, a driver for EKS, did in round five at Lydden Hill. This destroys the team’s weekend as the penalties are harsh: a 30-second time penalty if the Joker is missed during the qualifying heats, or a drop down the order to last place and consequent loss of points for missing the Joker during a semi-final or final. ‘It looks quite stupid when someone misses a Joker Lap or everyone goes into the Joker Lap at the same time,’ Hansen says. ‘The driver completely trusts the spotter, but the spotter doesn’t have an easy job. Also, sometimes the radio communication can break down at a crucial point, so the driver never receives the radio message and therefore misses the Joker.’ Punch line One of the few ways to try and add some certainty into the strategy is to analyse any trends as to when other teams usually take their Joker Lap. In this way you can then try and predict how the race will unfold and therefore when you should take the Joker. Typically, the privateer teams always complete the Joker on the first lap.

Therefore, it is almost impossible to go into each race with a clear picture of what is going to happen due to the uncertainty.
