SIGP returnees & debutants agree over challenging track

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.’

2025 1:10 Offroad World C/ships Chassis Focus Index

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, the year Kaerup came of age & became a double World Champion

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.’

Kaerup just holds off Ongaro to take A1

An intense A1 of 4WD at the IFMAR 1:10 Offroad World Championship saw Top Qualifier Marcus Kaerup just hold off defending Champion Davide Ongaro as the two Team Associated drivers dogged it out over the 5-minutes.  With Kaerup struggling out of the corners, Ongaro was all over the rear wing of the Dane making contact on a number of occasions.  The Italian’s big chance to go to the front would come as the race approached the final minute, Kaerup catching the pipe at left side double and coming up short on the landing.  However Ongaro would land on the inside pipe and miss the corner handing the lead right back.  With Ongaro then coming under pressure from the Xray of David Ronnefalk, Kaerup was able to bring home the win.  Having got by his team-mate Phend, when they touched wheels coming off the main straight & into the double double, the American coming off worst, Ronnefalk completed the Top 3 ahead of Mugen Seiki’s Burak Kilic and Schumacher’s Daniel Kobbevik.

Giving his thoughts on A1, Kaerup said, ‘The car really hard to drive, the rear was stepping out everywhere so I had to single single a couple of times to make sure I didn’t do the same as the practice final (he came up sort allowing Ongaro to go to the front).  Overall it was a good run and I just need to find some comfortability for the next one.’  On the error that allowed Ongaro to momentarily take the lead, the 17-year-old said, ‘the car was stepping out so I ran into the pipe and I couldn’t clear the jump.  Thankfully he hit the pipe on the landing and I was able to maintain the lead.’

Joking that the race was ‘super relaxed and nothing crazy’, Ongaro said, ‘Let’s try in A2 and see what happens, but actually we have the pace to be there.  I was a bit on one side unlucky when he missed the double and I hit the pipe but then was lucky to not flip so it was 50-50 on my side.’  On his car, the 3-time back to back 1:8 Buggy World Champion said, ‘It was super super good.’

Summing up his race, Ronnefalk said, ‘It was pretty good.  Unfortunately we were not close enough to the guys in front when they made some mistakes.  We were just a little bit too far back but stuff happens and I am sure Davide is not going to let Marcus win that easy in A2 so I expect the same things to happen.  We have got to be a little closer and try to pick up the pieces when something happens in front.’
