The action-packed 2010 FIA World Touring Car Championship series finally reached its closing round. The traditional Macau Grand Prix concluded the season on the renowned, exciting and challenging street track, Guia Circuit.

At the time when the previous Japanese round at Okayama had finished, both championship fights were to be decided in the final races at Macau. However, an unexpected turn of events brought about an unanticipated ending. The FIA Court of Appeal decided to disqualify the BMW's factory cars from the result of Okayama round for using sequential gearboxes and running their cars in lighter weight limit - even though the race stewards of the Japanese event allowed them to do so.

Consequently, their two drivers, August Farfus and Andy Priaulx lost the points they earned in Japan. This meant the drivers' championship hope was now out of Priaulx's reach and Chevrolet's ace Yvan Muller secured the title when the verdict came.

It might be unfortunate for fans that the drivers' championship fight ended out of track but it didn't detract the heat of Macau Grand Prix at all. As with WTCC, ADVAN has been designated as the official tire supplier of the F3 Intercontinental Cup and, even in other supporting races, many competitors chose ADVAN tires. Thus, the race weekend of Macau Grand Prix was strongly colored with black and red of ADVAN/YOKOHAMA.

The WTCC time table at Macau was a bit unusual and had to be modified further. There was a 30 minute special test session on Thursday prior to two 30 minute practice session on Friday. Then, according to the original schedule, the qualifying session, was run in the normal format - Q1 for all drivers and Q2 for the top ten, was to be held on Friday afternoon before a day off on Saturday and a warm-up session and two races on Sunday. But Q2 was eventually postponed to Saturday morning because the Friday's time table was badly delayed and the darkness fell before starting the session.

Being led by two Chevrolet drivers, Rob Huff and Muller, who started the race from the front row, Race 1 got underway but was immediately interrupted by Safety Car period. After a side-by-side battle with Tiago Monteiro's SEAT, Alan Menu running in third hit the barrier at Lisboa and lost a lot of ground. Then a few cars including Andre Couto and Priaulx made a contact, which required the intervention of the Safety Car.

As soon as the race resumed on Lap 5, Tom Coronel spun and Darryl O'Young (Chevrolet Lacetti) and Fredy Barth (SEAT Leon) weren't lucky enough to steer clear of it and they ended up with hitting the wall. O'Young was still contending for Independents Trophy but the disappointing retirement was a blow for his title chase.

After the second restart from Safety Car period, Henry Ho's BMW was stranded in the Solitude Esses on Lap 9. The track clearing work took some time and Race 1 ended under yellow flag.

Thus, in the eventful first race of the day, two leading Chevrolet Cruzes homed safely, keeping away from any accident, and Huff scored his third win of the season following the victory in Okayama. With Muller also adding some points by the second place finish, Chevrolet sealed the manufacturers' championship title. This was the first title in six seasons for the American marque which has kept its presence in the championship since the inaugural year of WTCC. They must be more than happy as the long awaited maiden titles came in a pair.

Huff got on the top place of podium at Macau for three years running. In the year before Huff's first, Menu had also won a race with Chevrolet Lacetti, so it could be said that Macau has been one of the Chevrolet's specialty tracks.

YOKOHAMA Independents Trophy was won by Kristian Poulsen. While Franz Engstler finished in second, the championship leader, Sergio Hernandez ended the race in fourth and this meant the championship winner was to be decided in the final race. By finishing in fifth overall, Norbert Michelisz secured the Rookie Challenge title for which only newcomers in WTCC were eligible.

For the 2010 season concluding Race 2, the pole position was given to Paulsen. The Dane became the early leader, as another front row starter, Menu, made a mistake to stall his engine at the start.

However, there was a multi-car accident in which as many as 12 cars were involved at Police bend on the opening lap. As the halted cars blocked the track, the red flag was put out to stop the race. All of the three Japanese drivers were involved in this accident and five retirements included Nobuteru Taniguchi, Yukinori Taniguchi and one of the Independent Trophy title contenders in this final race, O'Young.

After a 20 minute interruption, the race started again and the newly crowned Rookie Challenge champion Michelisz grabbed the lead position before the field reached to Lisboa. The 2009 drivers' title winner, Gabriele Tarquini, followed him but the Hungarian rookie gradually pulled away from Taruquini.

Meanwhile, the winner of Race 1, Huff - therefore starting from the eighth grid, made a hectic chase. He was 0.5 second behind Farfus at the end of Lap 3 but managed to pass the Brazilian three laps later at Mandarin Oriental bend and moved up to third. Then, Huff began to push Tarquini in second and their close battle continued until the checkered flag fell. Eventually, the ex-champion was able to keep his runner-up position and secured second place in the championship standings at the same time.

Michelisz scored the maiden WTCC victory in his rookie season. As he drove a diesel turbo engined SEAT Leon, he wasn't eligible for Independents Trophy but the team, Zengo-Dension, is pure privateer based in Hungary and has no direct relation with the ex-SEAT factory SR-Sport team. His overall win with a non- factory prepared car was only second example in the WTCC history, following the same feat achieved by Coronel who won a race in Japan in 2008.

By finishing Race 2 in ninth overall and ahead of championship rival Engstler, Hernandez won the Independents Trophy class and sealed his second championship title since 2008.
