Kato takes thrilling last lap SIGP victory in China

Infinity’s Kouki Kato has just taken one of the most exciting wins of his career, the Japanese driver winning the Sunpadow International Grand Prix after a thrilling last lap duel with Top Qualifier & majority race leader David Ronnefalk following 45-minutes of racing around the very challenging 3 Circles track in Xiamen.  With Chinese host track of the 2017 1:10 Offroad World Championships famed for its challenging bumpy conditions, it looked like Ronnefalk had taken control of the race with the main battle being for second place between Kato and his team-mate Bruno Coelho.  However a track that even the world’s best respect as being one of the most challenge there is, it didn’t take much for Ronnefalk’s lead to be eroded.  Passed by Kato on lap 56 of 80, the 19-year-old with hold the former World Champion at bay for 9-laps until a mistake with 7-minutes remaining, the local crowd invested in the racing and providing exciting audio as the leading drivers fell foul of track conditions.  Back in front and with the clock ticking down, Ronnefalk would again get tripped up by the track on the penultimate lap.  Coming of the main straight side by side to start the final lap, just as the computer signalled the finish of the 45-minutes, the pair took the jump on to the back straight and touched in the air both buggies tumbling but Kato having the better luck landing on his wheels.  While Ronnefalk tried to get back in touch over the remainder of the 34-seconds lap it wasn’t to happen and Kato took the win, the crowd appreciative of the thrilling finish.  Behind, by over 8-seconds, it was once again Coelho, winner of the eBuggy finals, who completed the nitro podium while Pekko Iivonen and Jung Hyunkyu were best of the rest in fourth & fifth.

Picking up over $2,800 for his win, which is put up event organiser Sunpadow batteries, giving his reaction to the race, Kato said it was ‘Very exciting, the last 2-laps everything changing.  We had a good weekend because Bruno win EP and I get Nitro, so a wonderful weekend.’  Running through his race, the 19-year-old said, ‘the car felt the best of the weekend in the final so they gave me the best car for the race.  Also, I did have some mistakes, but I also have good pace so I just kept trying for the win.’  On his fuel stops, the Japanese National Champion phrased his father and team-mate Coelho’s mechanic Ricardo Monteiro for their role in his win saying ‘they did a very nice job’.  Asked the significance of today’s win, him winning the final Philippine Masters Race to be run at the famed Circulo Verde track earlier this year, he replied, ‘here is probably one of my best ever races.’

Asked for a run down on what from a spectators point of view was a very exciting race finish, Ronnefalk replied, ‘I wish I had of been on the other side of that finish of course but it was Kouki’s day, he had more luck when he needed to there towards the end.’  He continued, ‘It felt like he crashed a couple of times and landed on his wheels and every time I had a roll out there I was on the roof so that’s what you need to win the races and the luck wasn’t on my side in the last 5-minutes.’  His second time attending the SIGP Offroad race, he added, ‘this is not a track you can step down in terms of driving because you are going to miss your marks out there and lose a lot of time.  You have to push, I tried, but I had a tap there on the second to last lap on the pipe, saved it, he got by, and on the last lap he went a little wide on the difficult jump section coming on to the back straight.  I dived on the inside and we went side by side over the first jump and we both tumbled.  I ended up on the rough and he was the wheels, that’s it not much I could do.’  One the gap he had established in the middle of the race he said, ‘Everything was working very well but I had two rolls two laps in a row after building up like a 10-second cushion and both of those times I was on the rough so I needed a marshal and brought them back into the game.  It is frustrating when you lead like 95% of the final and then you don’t come out on top but it was a good race and it’s intense when you have that close of a battle.  Your not justing battling the guy, I feel like more here you are battling the track out there so that’s offroad.  It’s not many times you race on a track like this anymore so it’s good to feel what it used to be like in the old days I guess.’

Summing up his race as ‘tough’ Coelho explained, ‘I had some very good momentum in the final and some bad.  I felt like sometimes the car was really good and on rails but then I would grab some hole or something and I’d flip and then it was difficult to get back to the pace.  It was very difficult to keep that momentum during the 45-minutes and I think that is what cost me the fight for the win because I can’t say I would have been in front of everybody but I am sure if I didn’t make the 10 or 12 mistakes I made in the final I would have been with them in the front.  I was still not far away from them 5-6 seconds from them.’  With himself and Kato running together for much of the race, on this he said, ‘I would make a mistake and was able to catch him, and then another mistake and able to catch him all the time like this, until I make 2 or 3 mistakes in a row that pushed me back a lot.  My last 15-minutes were very good but not enough to catch back up.’  Also finishing third last year behind Italian duo Davide Ongaro (winner) and Top Qualifier Mattia Polito, asked how this year’s track conditions in the final compare, the reigning Touring Car World Champion replied, ‘It was probably a little bit easier to this year because last year was super slippery.  It was even more difficult to jump more jumps and this year you were able to jump so I would say a little bit easier than last year but still challenging.’  He added, ‘This is a very old school track so it’s the kind of track where the tyre doesn’t really make a huge difference but everyone was actually on the same tyres so it looks like a controlled tyre which is very good because that is were comes the pace.  The track is very rough and you need to be very calm but at the same time you want to capitalise and move forward but sometimes you pay for that.  I like it a lot and it is really challenging and always very difficult.’

Asked about his race to fourth, SIGP first timer Iivonen said, ‘It started quite bad, I made a couple of stupid mistakes.  After that I couldn’t really catch the guys and made some other other mistakes and then I stated to hear that my gears were cracking so I just wanted to save it til the end.  At least that paid out’ – the Finn collecting 3,000RMB in prize money for his efforts.  Summing up his first experience of the SIGP, the 19-year-old said, ‘it’s a tough track so I think I did quite good overall.  My pace was there but I had a couple to many mistakes and maybe the cars were slightly too hard to drive.’   Asked if it was a track he would like to take on again, he said, ‘I think I would be happy to come back here for sure.  I would say like David (Ronnefalk) this is old school kind of racing.’

Kato & Coelho win Semi Finals at SIGP

Infinity pairing Kouki Kato and Bruno Coelho have won their respective Semi Finals at the SIGP in China, with Kato’s winning time meaning he leads the charge behind David Ronnefalk, the Xray driver locking in his spot in the 45-minute final yesterday when he claimed the overall TQ.  Qualifying third, and fresh from taking the overall win in eBuggy, Coelho would lead away the first of the 25-minute Semis ahead of young Korean talent Jung Hyunkyu and Mayako’s Joseph Quagraine, that order still the same at the finish.  Missing out on the TQ on tiebreak and starting the second Semi on pole ahead of fellow SIGP debutant Iivonen, Kato would run a much faster race time than his team-mate him crossing the line in 44/25:09.945 compared to Coelho’s 44/25:18.462.  With Iivonen second, also with a faster time than the first Semi, the Finn will start 3rd ahead of Coelho with Hyunkyu’s Associated completing the top half of the starting grid.  Reacting to his Semi win Kato, who switched to Hotrace’s Bangkok tyres, said,’I feel my car is super nice now but the track is getting more bump and also traction so its super difficult to drive.  I had many mistakes over the 25-minutes.  Starting 2nd I think I have a chance for the win.’

Asked how the track was after his Semi final experience, after taking some time to consider his response, Coelho said, ‘Challenging is one thing, rough is another one.  I think it is pretty rough the track right now.’  A driver well aware of the gruelling final that lies ahead having finished on the podium here last year, he added, ‘It will be super tough to drive the 45-minutes on these conditions.’  Opting to switch from Sahara to Napoli tyres for his Semi, a decision he admitted he was lucky to get away with he added, ‘the car was really difficult to drive right now so we will see, it is about surviving I think.’  For the main he will fit a set of Hotrace’s Bangkok tyres to his IFB8.

Coelho takes eBuggy win at SIGP

Bruno Coelho has taken the eBuggy win at the annual Sunpadow International Grand Prix, the Infinity driver pocketing himself almost $2,800 for his efforts around the challenging 3 Circles track in Xiamen, China.  Lining up as the Top Qualifier, the Portuguese driver taking pole position counting 2 TQ runs & a P2 from the 5-rounds of qualifying, it would be the Xray of 2024 winner David Ronnefalk who would be his biggest challenger in the finals.  Starting from P2 on the grid having topped 2 qualifiers together with a P3, Ronnefalk would have the fastest car in A1 and while the Swede piled the pressure on Coelho he couldn’t find a way to the front, a number of mistake meaning he had to catch back up for repeated attempts.  In A2 again Coelho wasn’t the outright fastest on the bumpy track but he had the consistency and after some early challenges from Ronnefalk he would take win to wrap up the overall victory.  Ronnefalk’s challenge ultimately ended when he tangled with third place qualifier Kouki Kato, waiting on the Japanese driver who needed to be marshalled after the contact.  With Kato’s Infinity recording the fastest lap he would finish 2nd ahead of Ronnefalk as they both retook the Mayako of Pekko Iivonen who buckled under the pressure while holding second going into the final stages of the race.  With Coelho using A3 as a test session and not taking up pole position, the race would see Ronnefalk take the win ahead of Iivonen and Kouki, the latter have a costly off while holding second and having to work his way back up in to the Top 3.  This result meant Ronnefalk (2nd) and Kato (3rd) would join Coelho on the eBuggy podium while Iivonen claimed fourth ahead of Team Associated’s Jung Hyunkyu and SIGP regular Joseph Quagraine.

A driver who has enjoyed a long term relationship with Sunpadow as his battery sponsor, reacting to his win, Coelho said, ‘It is always fantastic to win at Sunpadow, it’s always great to be here and say thanks for all the support during the year.’  He continued, ‘The track is very characterful.  I know it doesn’t suit maybe everybody but everyone who comes here knows it is like this and it’s very tough.  It’s almost like the TITC (touring car race in Thailand), it’s a track that is not fantastic asphalt but every goes there every year because it is very challenging and I think this race is exactly the same as that.  You need to work a lot and make the car good for the race.’  On the eBuggy finals, the winner of the SIGP Onroad race earlier in the year said, ‘The first A-Main was very tough with David all 10-minutes.  He would do some mistakes and come back very strong.  I just wanted to play safe to get some result because in such tough conditions it is very easy to make a mistake and be back in the pack fighting for the middle positions which is always very hard.  So I just tried to not force anything and just drive and finish the run, and luckily for me the other guys were doing many mistakes.  David made a lot of pressure and for the last three laps we were very close together.  I was defending well and he was also attacking very well & very respectfully and we finished 1 and 2.  In A2 I tried to be more aggressive and not as defensive as A1 because I already had one result.  I think I was able to show a little more pace and then slowly pulled away.’

Ronnefalk is Top Qualifier at SIGP as Coelho takes Q5

David Ronnefalk is the Top Qualifier at the 2025 Sunpadow International Grand Prix, the Xray driver securing his direct stop in tomorrow’s 45-minute Main in Xiamen, China, thanks to his outright fastest TQ run in the penultimate qualifier.  With it all to play for going into the fifth & final qualifier, Ronnefalk and Infinity’s Kouki Kato both having two TQ runs each and a second, neither would be able to deliver a third TQ run.  Instead that would come from Bruno Coelho, the Infinity driver appearing to have finally found his way just in time for finals.  After a trouble start to the day, with Q2 & 3 becoming throw outs, Pekko Iivonen was another to conclude qualifying on a positive as he set the second fastest time in Q5 with his Mayako.  Overall while Ronnefalk doesn’t have the worry of Semi finals, the TQ secured on the tiebreak, in the final qualifying order it was Kato who ended up second to give the Japanese driver pole in the second of the 25-minute Semis, while Coelho’s 3rd overall means he lines up on pole for the first Semi.  Iivonen’s strong finish to the day bumped him up to 4th ahead of leading Team Associated contender Jung Hyunkyu while Jason Nugroho made it three Infinity IFB8s in the final Top 6 qualification ranking.

Asked about the run that gave him the TQ, Ronnefalk said, ‘Q4 was really close between me and Bruno the whole run.  He was behind me starting on the clock maybe 3 or 4 seconds behind and I felt it was pretty much the same gap the whole 8-minutes even with the pit stop.  Towards the end I didn’t really remember where he started exactly, I had a point on the straight where I passed and he was on the jump section but I felt like I was always just a little bit ahead and I tried to push until the end without making a bobble and luckily it worked out and I was able to get the TQ and did so with the faster time which was a little surprising cause the track was a little slower than the previous rounds.  It was a mistake free run and that gave me the TQ because of the fastest time.’  On the last qualifier the 2016 World Champion said, ‘I had a silly mistake on my own.  I felt like jumping short on the back straight was a little bit better for me and then I just jumped way too short and cased the jump and crashed onto the infield and lost 6-7 seconds.  I didn’t change anything from Q3, I kept the car the same and just tried to work on my driving and try to follow how the track develops.’  Looking to tomorrow he said, ‘I just spoke to Max (Lim) and he said they are going to fill the worst spots on the track where the biggest holes are so the beginning of tomorrow should be smoother out there but towards the end I don’t think what they are going to fix is going to hold up throughout the whole day, so in the nitro main it is definitely going to be rough like it was now and it is going to be a challenge for sure.’  On tyre wear Ronnefalk feels it was higher the first day of the event and it has since got a little bit better so he feels they should all be good on the Saharas adding ‘it’s not the easiest tyre probably out there but it’s definitely the faster one, I think Bangkok would be a little easier to drive but it doesn’t have the forward bite that the Sahara has so we just have to make it with the Sahara it looks like.’

On his final qualifying attempt needing a faster TQ time than Ronnefalk’s Q4, Kato explained, ‘I tried the shocks from my EP car and the Bangkok tyre because the track is getting dusty and the car was OK but it was just my mistake, 3 big mistakes.’  Asked the different between his nitro and electric buggy shocks, the newly crowned Asian Buggy Championships Champion said the EP runs a softer spring.  Asked his opinion on tyre wear in the final, the 19-year-old replied with ‘it is going to be very difficult’ while also adding that when it comes to fuel strategy his plan would be to ‘play it safe’.  On EP, him lining up third on the grid for the triple A-Main, he said while he had a big mistake at the beginning of Q5 the car ‘was nice’ and he is confident for tomorrow.

Reacting to his Q5 TQ run an upbeat Coelho said, ‘Finally a TQ run the nitro class.  The car got better and that is a good sign to get a TQ run on the last one because it is more close to the track conditions we are going to have tomorrow (for the final).  We improved the car a lot this round, the car was much more safe to drive.  It was a clean drive for the 8-minutes, just 1 or 2 bobbles but the track was really tough to drive.  We changed a lot the geometry on the front of the car and also the shock package and I was much more confident now.’  Asked how he would say they track is now the 2024 podium finisher replied while laughing ‘destroyed I would say’.  He added, ‘I cannot say this is the best conditions for me because I am majority like an onroad driver, my main class is onroad, so offroad is OK when it is not like this but somewhere like Portugal – flat just with jumps.  These conditions are very tough for me but if the result is coming this means the car is very good so I am positive for the finals.’  Asked if he expects tyre stops in the final, Coelho replied, ‘It might happen, the tyre wear is pretty high so it might happen because the track tends to break down more & more which means a lot of dust on the track.  Now we are running on Saharas which is like no pin which means they become slick very early in the final, it will be for sure very difficult.’  Securing the overall TQ in eBuggy ahead of last year’s winner Ronnefalk, on that he said, ‘Electric was good.  The last round the car was very very good but I had a big crash at the beginning and I lost immediately 4-5 seconds but after I was able to recover and still be second (in Q5) so the car is good and I will just try to keep on the wheels tomorrow and don’t make any mistakes.’

Summing up his strong finish to qualifying Iivonen said, ‘I think the qualifying ended at the right time because right now the pace is right there and the car actually feels super good.  I feel quite confident going into the mains.’  The Finn continued, ‘There will be some mistakes for sure, it’s quite hard to go around the track, so anything can happen even in the eBuggy finals and of course in the long nitro final everything can happen.’  Making his first World Championship final earlier this year at the inaugural IFMAR eBuggy Worlds in Portugal, he added, ‘Now my cars were the best and also the tyres.  I ran Saharas today and that has been the best tyre so far and now they are fixing the holes so for sure tomorrow it will be the same case.’    On the improvements to his cars, the 19-year-old said, ‘I had some bad luck in the qualifiers today but ended out ok.  We found some shock stuff, we have TRC here and they are going a good job with our shock package and we have been working hard changing shocks for every run and I think now it paid off and we have found the best one so far and it will be good tomorrow.’

On his final qualifying position of P5, Hyunkyu said, ‘It’s not bad.  My car was not that bad compared to the last run but I had a stupid mistake on the entry to the pit lane and two mistakes on the right side.  So I need to work on getting the car more comfortable on the right side.’  Starting P5 in the eBuggy Main, the 14-year-old said, ‘the electric was so good, I got P3 the last round, so electric was good and I am looking forward to tomorrow.  For the (Nitro) Semi I will change the set-up because I lose sometimes the rear so we’ll see what happens tomorrow.’
