Japan’s Kouki Kato is the top seed at the SIGP Offroad Race in Xiamen, the Infinity team having the early advantage in China on the challenging 3-Circles track as team-mate Bruno Coelho managed to set the second fastest 3-consecutive laps. Over the two rounds of controlled practice Kato would set his best time in CP1 while Coelho would top the second round improving on his earlier time but unable to better that of Kato. Fresh from his double win last weekend at the new Hongyu GDC track in Guangzhou, Xray’s David Ronnefalk completed the Top 3 with his opening effort. Building his confidence on the bumpy track, Korean youngster Jung Hyunkyu took his Team Associated to the fourth fastest time ahead of Mayako pairing Pekko Iivonen and Joesph Quagraine.
A driver of few words, asked about seeding Kouki said, ‘The first one was very good but for the second one we made some camber changes and also changed the engine which took time to get right but I think we will go back to the CP1 set-up for the first qualifying.’ Pleased to have to deal with less traffic today, yesterday’s session open by class making for a lot busier track, the 2025 Asian Buggy Championships Champion said it is still hard to get around without mistakes. Running on Hotrace’s Sahara tyre, he added, ‘3 laps is already hard to make consistent so 5-minute is going to be very hard’, those were his thoughts before finding out qualifying will in fact 5 rounds of 8-minute heats!
Second fastest in Nitro but the Top Seed in eBuggy from defending class Champion Ronnefalk, Coelho said, ‘The second one was better for nitro, electric was pretty good in both seedings.’ The Portuguese driver, who is an SIGP regular both for the onroad and offroad events, added, ‘In nitro the first round was a bit tricky, the second round I had much more confidence so like I said yesterday it’s all about being consistent and not doing any mistakes.’ He continued, ‘The track is getting more and more bumpy. Yesterday at the end of the day it was really tough to drive on the track. They fixed it overnight but I heard they are not going to fix it until Sunday now which means the track is going to get worse and worse over the event so we need to be ready to have car easy to drive and have the shock package well set-up for the tough conditions that are coming. We also need to keep calm and learn the new lines that are coming.’ On his buggy set-up changes between rounds he said, ‘we changed quite a lot, we went more in the direction of the electric car. As we have two cars and the platforms are very close, so we tried two directions to know which one to go with and then we decided to go in the electric direction.’
Summing up his seeding performance Ronnefalk said, ‘The first nitro run was good. I was a little behind Kouki I thought but the pace was pretty strong and then we changed a couple of things for the last one to try a little bit on the tyre and the shock package and it wasn’t any better so we are just going to go back to what we ran in the first seeding and it should be all good.’ The Swede continued, ‘I just find out that, I mean I should have known, but I got to know they are 8-minute qualifiers so I guess we are going to see some pit stops in the qualifiers.’ He explained, ‘the lap is pretty long, you have an out lap, and then like if cross at like 7:50 you probably need like 9:20 to be safe on fuel.’ On his eBuggy he said for the first run his shock package was too stiff for the bumps, which made the car very sensitive, and he also had a lot of traffic in his heat. Redoing the shocks for the second one he said ‘it was a lot better.’
Giving his reaction to seeding, Hyunkyu said, ‘It’s not bad for me. My car is better compared to yesterday but I need to do more work to find a good set-up but I think we are on the right way for sure but its still quite off pace compared to Kouki, Bruno, David, and Pekko as well.’ He continued, ‘I will try some different things for qualifying and we will see how it goes. Having spent time in Italy with his World Champion team-mate Davide Ongaro testing at the Ongaroring as well as running a round of the Italian National Championships, asked if last year’s SIGP Champion was offering him any set-up advice, he replied, ‘I spoke with Davide yesterday and he gave me some pretty good advice but I need to figure things out by myself. I am driving here, he is advising from watching my videos.’ The 14-year-old continued, ‘I think the tyre is pretty important and I don’t have many set of bar tyre, I think everyone else is using the bar tyre right now, so I will just try to find the best set-up with JConcepts. I think it is good right now but bar is better. I only have a few sets of bar tyres so I save them for tomorrow.’
Asked how seeding had gone for him, Iivonen replied, ‘Not too bad but I just need to find a bit of pace to catch Bruno and Kouki. I think the car is quite easy to drive so it should be easy to make the apparently 8-minute qualifier, with one pit stop in there, but I think with a bit more steering and support in the rear the car will be super good. I am looking forward to the qualifiers. On his eBuggy, the Finn said, ‘electric was kind of the same, I just need to find a bit but pace wish electric is a bit better than nitro at the moment.’

After successfully returning to the international 1:8 Offroad race calendar last year, the latest edition of the Sunpadow International Grand Prix is under way with the moving of the race date to a month earlier than last year making for much warmer conditions. The 2017 IFMAR 1:10 Offroad World Championship host track’s signature annual event, there also an SIGP Onroad race earlier in the season, last year’s winner Davide Ongaro is absent from the entry which is now headed by last year’s eBuggy winner David Ronnefalk. Fresh from a double win at the opening race of the new Hongyu GDC 1:8 Offroad track last weekend in Foshan, drivers making their way between races on the China’s bulletin train system, Ronnefalk’s main challenge is going to come from his old team-mate Bruno Coelho, the then Xray driver finishing on the SIGP podium in the nitro final. Now part of the Infinity team, the Portuguese driver is joined at the 3-circle ARC International RC Racing Track in Xiamen by Kouki Kato, the Japanese driver making his 1:8 Buggy debut on the large track which is built on the grounds of the massive Sunpadow batteries factory. Also making his SIGP debut, Pekko Iivonen joins his returning Makayo team boss Joseph Quagraine, in taking on the challenging track the Finn more enthused about the track conditions than his main rivals for the large cash prize fund on offer. With no Ongaro this year, Team Associated will be pinning their hopes on young up & coming Korean talent Jung Hyunkyu, who like Ongaro last year is struggling to get to early terms with bumpy track.
Summing up the track after Thursday’s free practice, Ronnefalk said, ‘The track is similar to last year but a little bit more grip. I felt last year with the temperature being cooler it was a bit more slick on top and that was a big challenge for us then but this time you have the grip. The amount of bumps & stuff is the same pretty much. Last year we were sliding and then grabbing the holes, now we have the grip and we are driving through the holes a little harder. So this requires a little bit of a different set-up with the tyres and the shock balance but in the end it was pretty close to what I ran here last year.’ Asked about coming off his double win last weekend, the Swede said, ‘I think this is the complete opposite to what I ran there last weekend. There we were really fast so hopefully we can fine tune it tomorrow and be ready for qualifying here too. It is a pity the competition is a little less this year compared to last year but we are going to try make the most out of it and so far so good today.’ As last year’s eBuggy winner asked how each of his buggies have been working he said, ‘the schedule was pretty tight today running 2 times in an hour so I already decided to go with only one car and that was nitro. Then once that was feeling good I just changed the whole electric (buggy) to the set-up on the nitro and made one pack this afternoon and the electric car was feeling good too.’
With this race last year marking his final Xray outing after a successful decade with the Slovakian manufacturer, wrapping up Thursday’s practice Coelho said, ‘It’s tough as always, the track is very challenging and always changing getting more and more bumpy during the day but we know and already expect this’. Claiming the final step on the podium in Nitro Buggy last year behind Ongaro and a very impressive Mattia Polito in second, he added, ‘It is a race that is very tough and we need to work a lot on the car and be very careful with everything. We want to go faster but we know we cannot so we need to be patient and work on the car to make it safe and easy to drive. With electric I am pretty happy at the moment, with nitro we have some more to do.’ The reigning Touring Car World Champion explained, ‘because the car is always jumping it is a kind of mix. When it has the wheels on the ground it is very good but as soon as it starts to jump it is very difficult to drive.’ On this year’s grip levels, the temperature hitting in the range of 30 degrees today, he said, ‘last year we had a heavy rain which made the track very polished on the top and the cars were sliding all around. This year we had no rain and I don’t expect any rain before Sunday so the grip is like it was at the beginning of last year. The grip I would say is not high but medium.’
While he raced here previously 8 years ago when it hosted the IFMAR 1:10 Buggy World Championships, giving his first impression of the track for 1:8 Buggy, Kato said, ‘It’s a big track and the traction is ok but there are many bumps.’ The new Asian Buggy Championships Champion, added, ‘It is a challenging track but a super fun track drive, I’m enjoying it.’ Finishing the day’s practice, things getting more official tomorrow with seeding and the first two of the 5 rounds of qualifying, with almost half his Lexan rear wing missing, he explained, ’There was a lot of traffic and many crashes, so my bad.’ On the switch from last weekend’s low traction conditions of the covered Hongyu GDC track to the higher traction here, he said, ‘the traction is quite different because GDC is quite low. Will still need some fixes but I think I am already fixing things n the right way so I think we are looking good for when racing starts.’
A driver who is enjoying a jet set 2025 season that also included him making his first visit to Australia where he took on Round 3 of the Asian Buggy Championships in Bribane, giving his thoughts on the SIGP track Pekko said, ‘I think it looks quite cool. It’s a nice big track and I think it’s kind of how I like it, more like offroad to have some bumps and character. I think it will be a good race for sure.’ Describing traction levels as ‘medium grip’, the Finn continued, ’so we have the grip and there are sharp kind of bumps so that doesn’t make it easy but I think it will be nice racing here.’ On his car and asked if had change much over the and after coming from Hongy GDC, he replied, ‘Not too much. I will make for changes overnight, change the diffs oils because we didn’t have much time today. Today was almost all about trying to get as much track time as possible for me because I have never been here but other guys have been and the layout is the same as last year so I just wanted to get laps in.’
Asked his initial opinion of the SIGP track, 14-year-old Hyunkyu replied, ‘The track is so difficult. I think the shock set-up is so important here because it’s so bumpy.’ He continued, ‘Today was a bit of a lost day for me. We tried to find the right shock set-up but in the end we couldn’t find it today so I think I need to try a different piston tomorrow and see how that goes.’ In terms of the track he is used to racing at at home, the 14-year-old said, ‘It actually pretty big compared to my Korea track and it is my first time to see this like high grip and a rough track. It’s a pretty difficult track so I think the car is pretty important here. We will see tomorrow, I need to do fine tuning.’ Coming off his podium finish at Hongyu GDC last weekend he said ‘its a completely different track, there is low grip while here it is high grip & rough.’
It is one of those World Championships that will be etched in the memories of everyone for many years to come both in terms of the dirt track racers got to race on, the new World Champions that were crowned, and the great efforts of the Hills RC Off Road track to put on a World class event that marked the 40th anniversary of the 1:10 Offroad World Championships. Thanks to Radbody, Red RC was able to make the trip Down Under and witness the crowning of two new World Champions – Broc Champlin giving Schumacher their first title in 2WD and Marus Kaerup taking the Team Associated’s tally to 35 with his 4WD victory!! As we experienced during our coverage of the recent inaugural 1:8 Electric Buggy World Championships in Portugal, manufacturers where being protective of the set-ups/new parts and again we had to wait till after racing was complete to get to photograph some of the buggies. The most exciting Chassis Focus would be the brand new Mugen Seiki 4WD. While it has been raced before by Burak Kilic at the European Championship, we were honoured to get the permission of its designer Shin Adachi to unveil his latest work to the World. Kyosho came to Australia with some new designs for its upcoming 4WD buggy release but they were not quite ready to unveil it to the World. We managed to photograph buggies from 6 manufacturers including the two winning buggies and we have compiled the 9 buggies we got our hands on in our latest Chassis Focus Index –

2025 will go down as the year the Danish teenager Marcus Kaerup came of age with the Team Associated driver becoming the new IFMAR 1:10 4WD World Champion just 37-days after winning the inaugural 1:8 eBuggy World title in Portugal. The son of former European 1:10 Electric Touring Champion Jonas, becoming a double World Champion on a Monday was made even more special by the fact this time his dad was here in Australia as his mechanic – this father & son team’s working relationship & bond special to watch. Having secured the TQ, his second of the week as he also started on pole in 2WD, a podium the end result there, Kaerup would see off a brilliant title defence effort from his own team-mate Davide Ongaro. Taking the win in A1 ahead of the Italian, he would have to work even harder in A2 to keep his main challenger at bay, but he did to secure a title that is widely viewed as just the beginning, the legend of our sport Atsushi Hara one to tip Kaerup for greatest. With Ongaro going onto win A2 ahead of the Xray of Dakotah Phend, a long 9-days in Sydney would concluded with an AE 1-2 with Phend taking the final step of the podium. Driving his Mugen Seiki 4WD prototype, Burak Kilic would just miss the podium taking fourth ahead of European Champion David Ronnefalk.
Reacting to his win having had the opportunity to watch A3 from the sidelines and let the result sink in, Kaerup said, ‘It’s still completely unbelievable. I feel like this was way harder than Portugal because I didn’t have such a pace advantage but we managed to hold off Ongaro’s pressure.’ On that pressure from the 4-time World Champion he said, ‘He didn’t really let me off easy.’ With his father having been unable to travel to Barcelos for eBuggy but making the long trip Down Under for these Worlds, the 17-year-old said, ‘It’s more than amazing to have him here, he missed out on Portugal, so it was really special to have him here.’ Asked what goals he had for these, the 40th anniversary of the 1:10 Offroad Worlds, before boarding the long flight to the Hills RC Off Road track he revealed, ‘I didn’t even expect to be in the Top 3. I didn’t really do any practice for this event because the focus was on 1:8 but not winning the 2WD fuelled me to do everything I could for 4WD.’ Asked what was next for him, he replied, ‘Well I have a lot of school work to catch up on.’
Grateful in defeat, Ongaro said, ‘I am happy with P2, we were trying to defend my title but actually it didn’t work out.’ Coming close in A1 to a win on A2 he said, ‘I was confident with my car after Q5, I knew I had the pace to stay with Marcus but the track is really tight and lets say you can’t overtake easy so I tried to pass him fair because I can’t take him out. I tried it, I tried my best, and I gave 100% so I am happy.’ On A3 he said, ‘On the first lap I jumped a little bit short on the right step-up which cost me a little bit of time but then I was confident with me pace and I knew I was good. It was great to give AE a 1-2.’ He concluded, ‘next year it’s 8th scale, that’s the main one’, Ongaro going for an unprecedented 4-in-row in the USA in 2026.
Summing up his finals, Phend said, ‘Obviously the goal was to win, that’s why we come here, but a podium is still decent.’ The US Champion continued, ‘We definitely lost pace today come main time with the weather being a little bit colder and stuff. I made some changes and got it better for that last run, but yeah it is what it is and we did what we could do.’ Getting close to Ongaro for a time, he said, ‘I felt I was a little bit faster on the left side and was kind of able to reel him in there but he was able to gap me a little bit on the right side, so we yoyo a little bit. This track is really tough, you give a little bit of wheel spin it’s a couple of tenths.’
While making his first 1:10 World Final in Sydney and finishing fourth with a prototype car, which he has had little wheel time with, Kilic’s deep disappointment at missing the podium was written all over his face. With the Turkish driver, who didn’t have any pre-event experience of the dirt track, impressing many with how he drove in 4WD, the 21-year-old said, ‘My car and electronics were mega good and I drove good in A1 and A2 but I’m a bit sad to not make the podium but at least I made Top 5 with a prototype car on only the second time running it. It’s really promising and I will come back for the trophy in 2-years for sure.’ Only racing 3 or 4 1:10 events a year, 1:8 Offroad his speciality, the two 1:8 Nitro Buggy World finalist said, ‘Still Top 5 in the world is really good but I wanted that podium really bad, I just didn’t quite find the speed in the last one. I made a small bobble in the second lap, it was the first time I made a mistake in the triple.’
