Jack Young led home Max Coates for a Renault UK Clio Cup one-two finish in the special International Renault Clio Cup Finale race at Paul Ricard.
Both drivers had earlier taken a win apiece in the Renault Clio Cup Central Europe rounds across the weekend, while Brett Lidsey also starred in France.
Originally the top six from the 2018 UK standings were invited to take part in the event, but most declined so Young and Lidsey entered alongside Coates.
The end of season spectacular included races for the Central Europe, Italy, France, Spain and China series, before they combined for the finale.
The British trio were added to the Central Europe field for the weekend and instantly made an impact, with Young heading free practice before qualifying second.
Coates and Lidsey finished third and seventh respectively, with the former storming through to take a great victory in the opening encounter.
Young posted the fastest lap of the race but suffered misfortune and dropped back to fourteenth, though he hit back in style with race two victory.
Coates was hot on his heels to complete a one-two result, while Lidsey followed up a ninth place finish in the opener with a great fifth place in race two.
The three drivers replicated those results in qualifying for the International Finale race, joining two Clio Cup France contenders in the top five.
While Lidsey was unfortunately involved in a dramatic incident in the final race, Young and Coates excelled as they stormed to a one-two finish.
Young comes away with the honour of being the International champion and comes away with a brand-new Megane Renault Sport road car.
It ends a season in which the 17 year old, who is coached by BTCC champion Colin Turkington, became the youngest driver ever to take a UK Clio Cup pole.
“It was important I made the most of pole position in the Final. I just managed to keep Max behind – he was pushing like mad so I had to push even harder,” said Young.
“Somehow I’ve come out on top. A big ‘thank you’ to MRM for their support – I wouldn’t be here without them.”
Coates commented: “I felt like I had the pace to challenge Jack and was biding my time, but there was a safety car period and at the re-start he just got the jump on me and that was it.
“I had to defend my position a bit after that and he was gone. Second here having also come so close to winning the UK Clio Cup title… still it’s been a great year with lots of wins and podiums.”
