Jilles Groskamp is back on top of the World, the Infinity driver becoming the new IFMAR 1:10 Onroad World Champion at the Huge RC Circuit in Bangkok 12-years after winning the Electric Touring Car World Title. Having booked his way directly into the 1-hour Main by winning Super Pole, Groskamp would in the end cruise to victory to become Nitro Touring Car’s 10th different Champion as outgoing Champion Tadahiko Sahashi struggled in his quest to be the first driver to successful defend the title. Starting as the Top Qualifier, this being his second time to secure pole at the Worlds, Teemu Leino’s race lasted less than 10-minutes as the Finn flipped his Infinity after his second fuel stop and the impact with the boards broke a front shock. With 2018 Champion Naoto Matsukura looking like he was on to repeat his earlier dominant Semi final performance, as the race reached halfway and he had a clear lead over the field, a touch of the curbing ended his challenge. The subsequent impact after the roll would break a rear shock shaft but with the car still running on the spring he would limp home in P6, 7-laps down on his winning team-mate. For 1:8 World Champion Dario Balestri a dead receiver battery would cause him to crash out of a podium finish and DNF with just over 2-minutes to go. Behind Jilles, having managed to un-lap himself towards the end of the race, Capricorn’s Toni Gruber would claim second with tenth place starter Charlee Phutiyothin making it two Capricorns on the podium.
‘This one is special because my son was 2-years old when I won Electric Touring Car and this year my daughter is two and I win here in nitro’, was Groskamp’s reaction to his massively popular victory in a country that he used to call home for many years. Running over how his race unfolded the Dutchman explained, ‘It was a good start, I felt the car was easy to drive. Then Teemu rolled it and I was in the lead. In the first fuel stop we had a slow stop and Naoto went into the lead and kind of pulled away. I had already been a couple of times on two wheels and I knew my tyre strategy was only (to change) one side so I really had to drive my own pace and he pulled away a lot. After 20-25 minutes I was second but Naoto had a big lead so I thought I just continue to run my own race because something can happen and it did, I think he flipped and broke something.’ The now 44-year-old continued, ‘we then changed one side of the tyres which was a risk but I knew I could do it so after 28-minutes we changed and after only a few laps they came in and I had a good pace. Then Sahashi came in to change 4 tyres and I already had a lap & a half in front and from that moment on I just cruised around and tried to keep the car on four wheels.’ Describing the car as ‘quite difficult to drive at the end’ because of tyre size, he said, ‘I really drove the car as an EP car, I go slow in, use a lot of brake, just drive as smooth as I could, still I flipped one time at the end of the straight and from that moment on I knew OK I have to be very careful now so I let some guys go. I said bring it home safely and I did, so it’s amazing. I can’t really say how happy I am now. For sure Naoto was the fastest and I think I was the second fastest but that’s OK.’
Reacting to his 2nd place, after a long pause Gruber said, ‘On one side I am happy and can cry but now when I see only 13-seconds to Jilles when we had a flame out and I had a mistake & flipped, it’s hard to image what could have been without these’. The 2023 1:8 Onroad Vice Champion, continued, ‘starting from 8th and then having a flip that put me last, coming back step by step we where not so far away. We made some little changes after the Semi and it helped a lot the car so I could drive easier because I feel no flip but you never know if you push more if it is going to happen or not.’ Doing a full tyre change, he said unlike his rivals he never considered only making an outside change, and that his flip in the race was a result of touching the curb adding the first left corner ‘was always a critical point for my car.’
A previous World Championship podium finisher in 1:8 GT, Phutiyothin was delighted with his podium finish. The Thai driver said, ‘when we practiced here the car was very good but then once the event started the car was no good’ and he had ‘lots of engine problems’, however after a chassis and engine change on the day things counted most, ‘everything was super good’ with him stating ‘today was my day, the car was perfect.’ A finalist at last year’s 1:8 Onroad Worlds in Japan, choosing to change all four tyres during today’s final, he said everything ‘finally’ went as planned and he couldn’t have planned for the race to go any better.
Asked about his topple from the front of the race when looking so in control of proceedings, Matsukura, the only other driver to have won both the nitro & electric touring car WC titles coming in the race, said, ‘I just touched the inside curb a little too much and the car flipped into the wall which broke the shock. I still had the spring (keeping the suspension up) so I could drive the 35-minutes left.’ The only driver to run a 14-second lap in the final, he added, ‘in the beginning of the race the car was perfect, and I was just driving, driving, you know, but on this track it takes just one mistake.’ Originally planning to stop for tyres at 40-minutes, believing he had damaged his tyre in the impact he told his crew to change the outside tyres early which was when they discovered the damaged shock and he knew his shot at regaining the title was over.
Asked about his race, Sahashi replied, ‘the start was ok but then I struggled to see in the dark. The car was OK, the engine was OK, but the human not.’ With the final starting just after 16:36 local time while the covered track lighting was on, the lack of natural outside light did affect the brightness in the second half of the race. While in contention for a podium, he said after his tyre stop his car was ‘very difficult’ and having made the decision to run positive front camber as the tyres worn down it left him with a challenging car to drive at the end of the race costing him any podium chances.’

Tadahiko Sahashi’s 1:10 Nitro World Championship title defence is back on with the Infinity driver booking his place in final at Huge RC Circuit after finishing second to team-mate Dario Balestri in the second of the two Semi Finals. Having topped seeding, Sahashi then struggled throughout qualifying and found himself scrapping his way onto the back of a direct spot in the Semis. In the early stages of the final it looked like the Japanese driver’s quest to become the first back to back Champion of the class was over, however by the 10-minute he was up to third, helped in part by 2012 Champion Meen Vejrak and Takaaki Shimo both running out of fuel. Up front a flip by pole sitter Balestri allowed Chavit Saligupta to lead but shortly after third way distance his car came to a permanent stop ending his hopes of repeating his 2022 final appearance. Looking like he was safely into the final as he lapped in 3rd position there was a heartbreak for Australian Jessie Davis. With three minutes to go and having just exited pit lane his car came to a stop and with his engine refusing to restart his Worlds was done. Capricorn’s Thilo Diekman would finish 3rd to book the German’s first World Final start. In the other Semi, Naoto Matsukura looked like he was out for a Sunday drive, the 2018 World Champion lapping the entire field with a flawless drive that has the Infinity driver highly motivated for the final. Having started on pole, Capricorn’s Toni Gruber came home 2nd as he continues to challenge the might of Infinity here in Bangkok but the 1:8 GT World Champion admitted himself that his Semi performance was not a Title contending performance and they need to improve for the final. On the road it would be Viktor Wilck that would complete the Top 3 but his car would be deemed to be too wide in post race technical inspection and Charlee Phutiyothin was promoted to the final. The final two places on the grid would be decided on fastest times which went to Milan Holthuis and Sinnosuke Yokoyama.
Reacting to his Semi Final, finishing 2.6 seconds behind Balestri, Sahashi said, ‘I am happy. Qualifying was not good but now I am back.’ One of only two drivers to hold nitro onroad titles in both 1:8 and 1:10, asked about tyre wear he replied, ‘After 30-minute there was nothing left so the car had understeer and no traction in the rear so w must make one change in the final.’ On making changes to his car for the title decider, for which he will start P5, he plans to change the rear wing saying he feels a little less wing will give him a better car.
Summing up his race, reigning European Champion Balestri said, ‘It was super safe with the set-up, engine, carburetion set-up so we try to make something more for the final. It all went to planned, maybe a little too safe, but the point was to arrive at end and get into the final.’ A driver capable of becoming the first reigning 1:8 Onroad World Champion to also hold the 1:10 Title, the Italian said, ‘everything is on the limit here so we need to have an easy set-up on the car and engine set-up for a long final.’
‘I just drove around and did my own race. Today my car is very nice, I am so excited for the final’, was Matsukura’s reaction to his dominant Semi performance which as the fastest of the two encounters will see him line-up P3 behind Top Qualifier Teemu Leino and Super Pole winner Jilles Groskamp. Describing himself as ‘relaxed driving’ in the Semi, the only driver to be both a nitro and electric Touring Car World Champion said, ‘I hope I can do the same in the final and carry that momentum.’ Planning no changes for the final, on tyre wear he said, ‘I think the tyre is still OK (after 30-minutes) for me and my car was driving OK at the end but we need to check for the final.’ Impressed by his diver’s performance, master of World Championship winning pit crews Masayuki Miura described Matsukura as driving the Semi like it ‘was just a practice run.’
Asked about his Semi performance, Gruber said, ‘In the beginning we lacked a bit of steering because of the fresh tyres, in then in the middle of race the tyre was there but then it was critical to flip and I flipped one time. After that I took it a little easier to not flip again but overall the feeling of the car today is not so good, also the engine was a little too rich and that effected the shifting in the infield. Sometimes it change gear, sometimes it didn’t and that effected my driving and my confidence’. Asked about changes for the final, the German said, ‘We will change some very small things built not much, 1-hour is a completely new and different race.’
