The event was supported by the usual works entries from Citroën, Ford, Subaru, Stobart Ford, and Suzuki, plus regular privateers Conrad Rautenbach in his Citroën C4 and Mads Ostberg in a Subaru Impreza WRC. A notable omission was Urmo Aava who was scheduled to enter the event with his semi-works effort Citroën C4, but had to pull out only days before the event due to the ongoing economic problems. In another Citroën C4 was Frenchman Sébastien Ogier who was handed the drive as a reward for winning the JWRC category of the 2008 championship. The most newsworthy entry of all was that of 2008 Moto GP champion Valentino Rossi who was competing in a Ford Focus WRC complete with a Children in Need livery. Rossi was aiming to beat his previous two efforts in a WRC event, an early retirement at Rally GB in 2002 and an eleventh-place finish at the 2006 Rally New Zealand.
Summary
Day one
The rally began in tricky conditions with ice and heavy rain making the roads very slippery and fog hampering the competitors' visibility. For safety reasons, the first and fourth stages held in Hafren were cancelled. Stages 2 and 4 were slightly shortened and the third and sixth stages at Myherin were dramatically shortened, using the middle 18 km of the original 35 km. The FIA regulations came in for criticism from several of the teams and champion elect Sébastien Loeb for the lack of flexibility in the tyre rules which state that only one type of tyre is allowed on the event with no modifications allowed to that tyre. Loeb also spoke out against the lack of gravel crews, which run through the stage before the start and report any bad conditions to the drivers. The year's junior world champion Sébastien Ogier surprised by winning his first stagein a World Rally Car, albeit he was among the competitors to benefit from a late starting position. On the same stage, Production World Rally Championship leader Juho Hänninen retired after his drive shaft broke, leaving Andreas Aigner to take the title if he finishes the event in the top three. On the fifth stage, last year's winner Mikko Hirvonen rolled his Ford Focus WRC and lost several minutes. The next top entrant to roll was Subaru's Chris Atkinson, who was placed sixth before retiring after a bad accident on the first corner of stage seven, the first super special stage. After day one, Ford's Jari-Matti Latvala led from Citroën's Sébastien Loeb, Suzuki's Per-Gunnar Andersson and Subaru privateer Mads Østberg.
Day two
Day two began with a long stage in Resolfen. Two of the rally's surprises ran into problems; Østberg's Impreza WRC suffered an engine problem and Ogier rolled his C4 WRC very close to the stage finish. The crews reported more icy conditions in the stages, with Latvala feeling particularly ill at ease as he was the first caron the road and therefore the first to encounter the treacherous patches of ice. Throughout the day the conditions improved enough for Latvala to manage to hold off the challenges of firstly Dani Sordo, and then Sébastien Loeb. Latvala held a 10.8 second lead going into the short Cardiff superspecial but clutch problems developed when he had to queue in heavy traffic on the approach to the stage and he lost 3.5 seconds of this advantage. In fourth position was Petter Solberg who was only twenty seconds behind third place. Per-Gunnar Andersson had slipped back to fifth place, but was still three places ahead of his more experienced teammate Toni Gardemeister. The two other points positions were held by Henning Solberg and François Duval. Mikko Hirvonen was homing in on a world championship point, ahead of top home driver Matthew Wilson who was in a slightly disappointing tenth position. Valentino Rossi was making progress after a very steady start and was now in fifteenth position - ahead of WRC regulars such as Khalid Al-Qassimi and Conrad Rautenbach.
Day three
Freezing conditions overnight meant that there was ice again on the remaining stages at Rheola and Port Talbot. This was not ideal for rally leader Latvala, who had hoped for warmer conditions overnight for a better chance of holding Loeb at bay. Loeb had been told by Citroën boss Olivier Quesnel to push for the victory as a third place for Sordo would be enough to clinch the manufacturers title. After the first loop of Sunday's stages the gap was down to 1.4 seconds and a victory for Loeb was looking inevitable. Loeb was then initially handed a ten-second time penalty for a jump start at SS18 which meant that Latvala took a slender advantage of 2.2 seconds into the last stage. However, Loeb's pace was too strong and a further stage win meant that he won the rally by 12.7 seconds after his earlier time penalty was rescinded. Latvala finished a disappointed second but believed that the battle with Loeb would make him mentally stronger for next season. Sordo followed team instructions to drive carefully and finished third. Petter Solberg maintained his fourth place and the remaining points positions remained the same, except for a late retirement for Henning Solberg which meant that Hirvonen claimed eighth place. Wilson took the position of highest Brit position, ahead of Barry Clark. Rossi continued his progression and finished in twelfth position, earning praise from Ford team boss Malcolm Wilson.
