Newly crowned Monoplace Challenge champion Alex Peroni recorded a clean sweep of victories as he ended the season in fine style at the Estoril finale.
With the championship secured, Peroni showed his class by romping to his 14th race win of the season with a commanding drive in Sunday's final race.
The Hobart racer tamed a tricky damp circuit to complete a crushing 14 second victory for the TS Corse squad.
Before heading back to Australia, the rising single seater star will head to Belgium's Spa-Francorchamps circuit for a test with the renowned British squad Fortec Motorsport.
Peroni is evaluating a move to the hotly contest Formula Renault 2.0s Eurocup next year.
Formula V8 3.5
Tom Dillmann lifted the Formula V8 3.5 Championship following an impressive drive at the final round in Barcelona.
Dillmann entered the final race of the season six points adrift of series leader Louis Deletraz.
Deletraz finished second in the opening heat behind Egor Orudzhev, while Dillmann could only manage third.
The odds seemed to be stacked against Dillmann as he started the final race from seventh, while Deletraz was on pole position.
However, a poor start from Deletraz saw the Swiss driver drop four positions.
Meanwhile, Dillmann executed a perfect undercut to emerge from the pits ahead of Deletraz before charging on to win the race and secure the title.
Roy Nissany came through in second with Pietro Fittipaldi third and Deletraz in fourth.
As a result, Dillmann took the title by seven points.
Australian Thomas Randle retired from the opening race after suffering a DRS failure, before finishing 11th in the final race on his second appearance in the category.
Walter Hayes Trophy
Irishman Niall Murray produced a dominant display to win the prestigious Walter Hayes Trophy at Silverstone.
The annual competition sees the world's best Formula Ford racers compete in a series of knockout races before a final shootout.
Murray made swift progress through the competition ensuring his passage to the final by winning the first semi-final from countryman Wayne Boyd.
In the final Murray was in a class of his own as he took the crown by 8.5s from American Oliver Askew, while Josh Fisher was third.
Former Australian Formula 3 champion Joey Foster rounded out the top 10.
Meanwhile, Australian driver Scott Andrews missed out on securing a spot in the final after finishing 22nd in the first semi-final.
The Victorian racer, who finished third last year, began the weekend on the back foot with a gearbox problem.
Andrews did however produce a fine performance to win the Last Chance Qualifying Race from 33rd on the grid, that earned him a spot in the semi-finals.
Targa High Country
Victorian Matt Close has won outright victory and GT2 competition honours at Targa High Country at an icy Mt Buller.
Close (Porsche GT3) started the final leg with just a one second lead over fellow GT2 competitor, Tasmanian Michael Pritchard, driving a Dodge Viper ACR.
Overnight snow on Mt Buller saw Close adopt a cautious approach on the wet and slippery run down the mountain, dropping 16s to his rival.
But on the very next stage he bounced back, grabbing the lead on the 40km Jamieson test.
Close pushed on to extend his lead on every stage, finishing the three-day enduro 59s clear.
Third in the Mt Buller GT2 competition went to Craig Dean and Kate Catford in a 2015 Mustang Shelby GT, one minute 14 seconds further back.
Steven Johnson and Nathalie Ford were fourth in a 2010 Chevrolet Corvette ZR.
In Shannons Classic GT, Peter Nunn developed clutch problems in his 1985 Porsche 944 on the penultimate stage which handed the lead and the competition victory to South Australia's Craig Haysman, in his thumping 1979 Triumph TR7 V8.
Lindsay Stone and Simon Martin led from start to finish in their 1985 Mazda RX-7 in the Shannons Classic competition.
Alan Roe and Michael Lloyd took the Duttons Garage Early Modern honours in their 2000 Mitsubishi Evo 6.5RS.
In the RDA Brakes GT4 competition, Trevor Macleod had the highly experienced Steve Glenney calling the notes, and they proved a formidable combination in their 2010 Subaru WRX STI.
Anthony and Toni Rizzo continued their great form to take their 1977 Subaru WRX STI to victory in the Mansfield Shire GT Sports Trophy.
The combination of Brian and Justin Marshall, in a 2011 Volkswagen Polo GTI, proved too good to lead from start to finish in the TSD Trophy.
