France’s all-new world championship qualifier, which takes place in the country’s Alsace region from September 30-October 3, is set to be a Tarmac rally like no other with inconsistent stage surfaces, narrow and wide sections and temperature variation all adding to the challenge facing the competitors, more than 60 of whom will use Pirelli’s PZero asphalt tyre.
Based in Strasbourg close to the border with Germany, the bulk of the event’s 20 special stages are contained within hilly forest areas with the exception of Sunday’s runs: a 24-kilometre test through the Bitche Camp military training area, and a 4.10-kilometre blast through Haguenau, Sebastien Loeb’s home town.
Loeb, who can land his seventh world title by winning the event, is expected to dominate in his Citroen C4 World Rally Car. An established asphalt specialist, the last time Loeb was defeated on a pure Tarmac event was in Spain in October 2004 when he retired due to a mechanical problem.
“We saw in Bulgaria in the summer, a new rally for everybody, that Sebastien was a little bit ahead of everybody,” said Sven Smeets, team manager of the Citroen factory squad. “And we really expect him to be up front fighting for the victory in France where he can bring the championship home. There will probably be a little bit of pressure because it’s his home town and people expect him to win but we know his skills on Tarmac and Sebastien is never really under pressure.”
Pirelli, the official tyre supplier of the WRC under a three-year agreement with the FIA, motorsport’s world governing body, will supply the hard and soft compound variant of its PZero tyre to all crews in four-wheel drive machinery. The hard compound is designed for hot and dry conditions with the soft version better suited for cooler temperatures and a damp stage surface.
Matteo Braga, Pirelli’s senior WRC tyre engineer, says he expects tyre compound choice to have an impact on the final result.
“Although we expect Sebastien Loeb will be world champion, we know that the weather will be less easy to predict and this will influence the choice of tyre compound,” said Braga. “Okay, we have seen that the soft compound PZero tyre works well in warm and dry conditions but, in France, there is a chance of some rain so it’s likely we will see more soft compound tyres being used on this event. The quantities available have been selected with rain in mind so there is no problem with supply, the only concern is if it rains very hard, which it can do in the mountains.”
The tyre regulations set out by the FIA don’t allow for a specific ‘rain‘ tyre, nor do they allow the insertion of artificial ‘cuts‘ into the tread pattern to provide extra grip. The measures were all designed to ensure the tyre could be used on a wide variety of asphalt and in different conditions to ultimately control costs. “It means drivers will face a compromise if it rains and maybe won’t be able to push at 100 per cent,” continued Braga.
As with all rallies using mountainous stages, there is a constant risk of changeable weather conditions and localised precipitation. But even if it doesn’t rain, the stage surface is likely to be slippery in places according to George Black, the Ford team’s tyre technician.
Black has driven over the competitive route and described the problem of stage “pollution“, adding: “Because the rally is mainly in forest areas you have a problem of pollution with pine needles and leaves falling like snow on the road. It puts moisture on the ground and with the temperature quite cool in the morning it’s going to be quite a challenge. Apart from the Bitche Camp stage, no stage on the rally has one consistent surface with smooth, coarse and bumpy Tarmac, even gravel in some places, all featuring. It will compromise car set-up and make for a difficult rally.”
Black also pointed to the variation in stage width as being another factor on the event and singled out Friday’s 24.5-kilometre Grand Ballon stage, which reaches a peak of 1424 metres. “You’ve got single-width tracks and then when you approach the ski resort the road is very wide so you can straight-line lots of the corners. Then it’s narrow again through the trees and bumpy like hell. You will also have a big variation in temperature from start to finish.”
P1 and P2 drivers can select from a quantity of 24 hard compound PZero tyres and 22 soft compound PZero covers on Rallye de France. However, they cannot exceed 36 tyres for the entire event. All other four-wheel drive crews can select from 20 hard compound tyres and 16 soft compound tyres but are restricted to a total of 25 for the duration of the rally. Crews in the Junior World Rally Championship will use the RX tyre, available in 16- and 17-inch diameter.
Rallye de France is the fifth event of the season for the Pirelli Star Driver programme, a joint initiative between Pirelli and the FIA. It gives the opportunity for five promising young talents, Nick Georgiou, Peter Horsey, Hayden Paddon, Alex Raschi and Ott Tanak, to contest six rounds of the World Rally Championship in identical Pirelli-backed Mitsubishi Lancer Evolution Xs.
As well as counting as round 11 of the main WRC, Rallye de France is also round eight of the Production Car World Rally Championship, for two-litre turbocharged Group N cars, and round nine of the Super 2000 World Rally Championship, which uses normally aspirated two-litre cars. Pirelli supplies its hard and soft compound PZero tyres to both support championships, thereby underlining the performance and efficiency of the Italian rubber on a wide range of machinery.
Rallye de France features 351.80 competitive kilometres over 20 special stages. Action gets underway at 0843hrs local time on Friday October 1 with the final stage around Haguenau town centre set to begin at 1336hrs on Sunday October 3.
