The KWC championship started of as the Indoor Kart World Championship (also known as IKWC). It was raced for the first time in Phoenix, Arizona, USA at the track of F1 Racing Factory in 2005. For three years on a row we visited the USA. After victories by Werner Truegler and Alex Gumpenberguer from Austria in 2005 and 2006 respectively, the Brazilian, Rodrigo Faulhaber took the title in 2007.

In 2008 we left North America for the first time and we took the event to the track of Worldkarts in Kortrijk, Belgium. This was also the only time the championship was divided into two categories, +80kg and -80kg. Local driver Mathias Grooten took the victory in the +80 category. His fellow countrymen, Gregory Laporte won the -80kg category. This was also the first year we introduced Nations Cup, which was won by Bluestar Racing Team from Belgium.

Macae, close to Rio de Janeiro, Brasil was our next location in 2009. The race track was specially built inside a convention center for a period of thirty days thanks to the contribution of Petroleum & enegery PETROBRAS, a local sponsor.

The sixteen year old Brazilian, Maxwell Jansley took the title after a close and tough battle with the Belgian driver Kenny Geldhoff and local driver Gustavo Loureiro. Maxwell was also a member of Larimax, the winning team in the Nations Cup.

In 2010, KWC went back to Phoenix, Arizona. After showing his talent the year before in Brazil, Kenny Geldhoff took his first victory as a KWC Champion. This takes the victory count for Belgium up to 3, Austria and Brazil both have 2 titles. Nations Cup was not raced this year in Phoenix.

Eupener Karting, Belgium was our next stop in 2011. After a strong battle amongst Belgian and German drivers, Kenny Geldhoff took the victory and became the first two time KWC Champion. The Nations Cup title went to Bluestar Racing Team, where Kenny was also a driver.

In 2012, the KWC train made a stop in Essen, Germany where the Daytona racing track hosted KWC. It was a very tough competition between the Germans, amongst them Maximilian Beer and Maximilian Fritz, against the Belgian squad with Kenny Geldhoff, Mathias Grooten, Gregory Laporte and the equally fast Robin Borremans. The Nations Cup was won by the Germans with a brilliant victory. They started last after a first lap accident and took the lead in the last lap after a pit stop mistake by Robin.

In the individual championship the tremendous battle between the German and Belgian drivers continued. This time, Robin Borremans took the victory in the final race, supported by an international crowd. This was the first time KWC used a match race to determine the grid formation for the final race. Robin took the match race battle up against Maximilian Beer and also won the final leaving no doubts about who was the best driver on the track that week.

Next edition took place in the North. The host for 2013 was the great track of Racehall, Aarhus, Denmark. Amongst the participants we had Karting multi-champion and ex-formula1 driver Giorgio Pantano with his CRG Team. For the first time Indoor drivers in KWC would battle agains pro-outdoor drivers. Also the first time KWC moved up to 13hp karts to upper the challenge. Again Robin Borremans was very dominant. He won the title with convincing victories over Filipe Vieira from Portugal and Jannick Nielsen from Denmark.

In Nations Cup, Bluestar Racing Team invited Giorgio Pantano as a guest driver and they took their 3th victory.

Back to South America in 2014, with the FIA/CIK outdoor track in Campinas, close to São Paulo as a KWC host. For the first time in KWC history, we had chosen an outdoor track with, again, 13hp karts that were used. It was a very leveled championship and the local Mauricio Pereira that had won the brazilian championship several times, took the title in the final race. In Nations Cup, it was Team Mota, formed by Luir Miranda, Nicolas Costa, Matheus Porto, all brazilians, and the portuguese Felipe Vieira, that won the title.

In 2015, the KWC championship moved to Camerano, Italy. We used the state of the art KZR Padle shifter Karts tuned to 18 HP. The Belgian Mathias Grooten was dominating the championship and won the title by large margin, becoming the second two time KWC champion. For Nations Cup the history was quite different. The team Hola Lulu/Costa Blanca with 2013 Jr champ Giovanni Baccelieri, Matts Breckpott, Arnaud Teeuwen from Belgium, and Francesco Betti from Italy took the victory passing the Brazilian team 5 laps before the end of the race.

In 2016 KWC repeated Italy, but this time at Martinsicuro, using again the amazing KZR karts. This marked a change on KWC standings. The history above shows a massive domination by belgian drivers with the exception of the races outside Europe where brazilians and austrians played their part. Now it is the orange drivers from the Netherlands taking control. Seventeen year old Rico Haarbosch raced very well and took the title in the last race, leaving his countrymate Ruben Boutens in second place. The Dutch Value Team also picked the victory in Nations Cup.

In 2017, we moved to Karting Rivas in Madrid. We left the KZR´s behind and raced with 13 HP Dino Karts on a two floor outdoor track. The event counted with 180 drivers from 23 different countries. World ranked number one Ruben Boutens from the Netherlands finally claimed his long deserved title after finishing on the podium five times between 2009 and 2016. The runner up was his teammate and 2016 champion Rico Haarbosch. Mathias Grooten took Belgium to the podium, finishing 3th.

Nations Cup was taken home by the british team led by Sean Brierly, Sam Spinnael, and Mark Oddy.
