The 2017 UIM F1H2O World Championship reaches its climax with the final two rounds to be held in the UAE, the Grand Prix of Abu Dhabi (6-8 December) and the Grand Prix of Sharjah (13-15 December), writes Nigel Quilter.

Heading into the penultimate round at his team’s home Grand Prix, a circuit where he has qualified in pole three times and won three times, Abu Dhabi’s Alex Carella is tantalisingly close to chalking up his fourth world title in eight years.

The scenario for the climax to the year is simple; two races to go 40 points maximum on offer. Mathematically a clutch of drivers are still in with an outside shot at the title but the percentages are stacked heavily against the majority of them.

It looks to be a three-way duel between Carella, Sweden’s Erik Stark (below) and CTIC F1 Shenzhen China’s Philippe Chiappe, the defending world champion.

Carella is in command on 58 points with a 16 point advantage over Stark and a further three over Chiappe and one outcome in Abu Dhabi will seal the deal for the Italian driver.

If Carella wins, the title race is over with one race to go and he is champion for the fourth time. To keep the championship and their title hopes alive Stark and Chiappe simply have to finish ahead of him. That said, should any of the three front runners falter the flood gates will open and the permutations as to who will actually be crowned champion at year end are endless.

It has been a fascinating season that has seen three different pole sitters, Shaun Torrente in Portimao, Alex Carella in Evian and Liuzhou and Erik Stark in Harbin and three different race winners, Chiappe, Carella grabbing two and Stark.

The title race has swung one way then the other; Chiappe led after winning the season opener in Portugal leading home Mad Croc BABA Racing’s Sam Selio and F1 Atlantic’s Duarte Benavente. Carella grabbed the pole and race double in France but it was Selio who took over top spot in the standings with second place ahead of Victory’s Shaun Torrente, Chiappe (below) losing ground after failing to finish.

From Europe the tour headed to the Far East for its mid-term campaign in the People’s Republic of China and the pendulum swung again; Stark’s brilliant pole and race win in Harbin catapulted him right into contention with Carella now on top after a measured drive to fourth behind his Abu Dhabi teammate Thani Al Qemzi and Victory’s Ahmed Al Hameli. This time it was Selio who faltered, crashing out in qualifying and failing to go the race distance.

In Liuzhou Carella took control of his title destiny, going quickest in qualifying and then driving himself to near exhaustion to take the win ahead of Stark and Chiappe to extend his points advantage over both, with Selio all but conceding his title challenge was over after a second crash in qualifying and again failing to post points.

Twenty one drivers from 13 countries will line-up in Abu Dhabi with two newcomers making their UIM F1H2O tour debuts.
