The World Rally Championship will introduce digital chicanes for the primary time in competitors at Rally Finland, in a transfer that has helped re-introduce the legendary Ouninpohja stage.
The development in expertise has seen digital chicanes turn out to be extra prevalent in rallying with the system already being utilized in varied championships together with the European Rally Championship at Rally di Roma.
This weekend will see the idea graduate to the WRC following a take a look at of the system throughout shakedown at Rally Latvia earlier this month.
A digital chicane supplies a strategy to sluggish vehicles down forward of a difficult part with out organisers putting a bodily impediment for drivers to navigate round. As an alternative of utilizing heavy hay bales to mark out a chicane, organisers can now designate predetermined areas the place drivers are required to sluggish city o 60kph.
Digital chicanes can be deployed once more in shakedown in Finland and can characteristic within the Ouninpohja stage, which can be run twice as stage 13 and stage 16 on Saturday. Ouninpohja returns for the primary time since 2016 and is being run within the legendary 33-kilometre ‘lengthy’ format however in the other way this 12 months.
The stage is among the many most well-known in WRC historical past, identified for its high-speed jumps and its difficult sweeping corners and its return may be credited to the introduction of digital chicanes.
“It was nice for the organisers to ask about it [Ouninpohja’s return],” Nicolas Klinger FIA rally security delegate informed Motorsport.com.
“They needed Ouninpohja and to run it once more, however for certain we all know it is vitally quick. It isn’t in regards to the quick straights it [the virtual chicanes] are to keep away from coming into a dodgy nook that’s quick to decrease the danger a bit.”

Why are digital chicanes being launched?
As Klinger defined above one of many explanation why digital chicanes have been launched is because of security. The idea reduces the velocity of vehicles previous to a difficult part of highway and does so in a approach that additional reduces the danger with out utilizing bodily objects that would trigger collisions and trigger harm to autos.
Nevertheless, the development in expertise to allow occasion organisers to undertake such a system coupled with struggles to supply hay bales to designate chicanes has additionally performed a component within the rise of digital chicanes in rallies the world over.
“In some nations, they cannot have straw bales and it has turn out to be an increasing number of troublesome to get straw bales. Straw bales weigh 400kg and it’s worthwhile to transfer them, and in addition typically roads may be very slender, so you’ll be able to’t implement the chicane simply due to the width of the highway,” Klinger added.
“So, this is likely one of the causes and I’ve to say that expertise has modified, and it now permits us to do digital chicanes. It’s one thing which is run in Australia, in Netherlands, in Germany, in Italy as properly, so it isn’t one thing new. It’s simply utilizing the expertise that we did not have earlier than.
“For certain [safety is factor] as a result of sooner or later that may assist us and permit us to do different issues and go into different phases the place we’re not allowed to go.
“There may be additionally a sporting facet as everyone is slowing right down to the identical velocity [for the virtual chicane] so that you received’t have somebody who comes and pushes the straw bales after which the next automotive can go 20kph sooner and take benefit.
“In Latvia, it was not a take a look at for us. We all know that it really works it has been examined and in different nations, it was extra for the drivers.”

How will the digital chicanes work?
Rally crews will see indicators counting right down to the digital chicanes throughout the stage with the stage facet markers counting down from 300 metres right down to 100 metres earlier than the digital chicane zone begins. These warnings can even seem on the monitoring field situated within the cockpit of the automotive, the machine which additionally flashes up purple flag warnings throughout phases.
The automotive should decelerate to a most of 60kph throughout the 200-metre zone previous to the digital chicane. The monitoring field will present a inexperienced gentle when the right velocity is reached. As soon as that velocity is achieved the automobile can speed up once more.
Failing to decelerate to 60kph will incur a penalty of two seconds per each kph over the restrict and can be added to the general stage time.
