A decade on – life is different, but the drive & focus on winning in Chile are the same for Kurzbuch

2025 marks a decade since Simon Kurzbuch became the Champion of the World.  A driver Red RC have had the pleasure of following on his journey up through the ranks and into 1:8 Onroad racing history books, we first got to know him through the early days of the Euro Nitro Series and as one half of the talented Swiss racing duo that was himself and Silvio Hachler.  Unfortunately we would miss him claiming the biggest prize the sport has to offer, Brazil in 2015 the only 1:8 Onroad World Championship we have missed since going online in 2006.  Thankfully Simon, being the super nice guy he is, hasn’t held that against us and just before he caught his long flight to Chile we had a quick chat to get his thoughts on where he feels he is at as he attempts to become only the 3rd driver to ever win IFMAR’s original WC category more than once.  If he can pull off that feat he would also be the first non Italian to ever do so.  While legend of the category Lamberto Collari won’t be in Santiago for a chance at a 10th World title, and defending Champion Dario Balestri’s chances of a hat trick are on hold as he also wont be there, Simon did address the big talking point around this year’s 24th running of the Worlds – the absence of the entire Infinity team.  ‘I am disappointed that the Infinity drivers are not coming, it is a real shame for Kenji that none of them are coming, but no Infinity does not affect anything from my side in how we approach this race.  In the end there are still very good drivers there and you need to beat them and to beat them you need to work properly before the race in your preparations and then work hard when you get to Chile.  I have a really good focus on the race so from this side it does not change anything if Infinity are there or not.’

Now 33-years old, on where he expects his main competition to come from, without hesitation he replied, ‘Toni (Gruber), Shoki (Takahata) and (Andrea) Catanzani, Catanzani is fast and someone to really watch.  Maybe there will be some other surprises, we will see, but I think these are the guys.’  Asked the difference between the Simon of then (Brazil, 2015) and the Simon of now he replied, ‘There is not a big difference I would say.  A lot of things are the same, of course my focus outside of racing is a bit more into work.  Back at that point of my life I was studying and also had a great time with Silvio Hachler, who is a really good friend.  We studied together and could manage to do as much racing as we wanted to and it was an amazing time that time which also boosted us for good results and everything.  That is the main difference.’  He added. ‘On the other hand my father is still there racing with me and supporting me a lot.  Alex (Kempe) was also there in Brazil as support for Shepherd and now he is directly helping my father so we are looking forward to defend the title of South America.’  While the same dream team that helped him secure the TQ honours at the last World Championship in Japan 2-year-old, and this year’s European Championships, bSimon said it’s not quite the ultimate dream team, his brother having partnered his dad in executing the many pit stops en-route to becoming the World No.1 in Brazil.

Asked if 1:8 Onroad and its high revving little 3.5cc engines have notably evolved since the last Worlds, the class having had almost 50 years to perfect the concept, he said, ‘I think the engines made a big step again the last two years.  The cars have developed a bit also.  I see the difference with my new Mugen but also the other manufacturers have worked to get more from their cars so it is for sure a bit faster.’  On engine and in particular his own program with Ielasi Tuned, owner Daniele Ielasi a rival in Brazil but now one Simon’s key sponsors along with Energy Fuel, who supplied the control fuel for both the 1:8 GT and now the 1:8 Onroad Worlds, he said, ‘reliability is now on a really really good level compared to what we had over the past 10-years in our sport.’  He added this is the result of ‘development but also hard work from Daniele.’

Showing that their is no doubts over his outright speed in terms of being one of the fastest drivers on the planet taking the TQ in Japan on Infinity’s home ground only for a wing issue and engine tuning to thwart his effort in the final, Simon said, ‘this year at the Euros I could manage to TQ against all the Infinity guys and everyone so the speed is there yes, for us it is important to have a clean final.  That is the main focus and it’s been the focus for the last weeks and months in preparation to have more consistency there.  Even though in the last ENS it was not the perfect final race practice but things that happen you learn from them and they are over’.  Suffering a flameout in the last fuel stop at the ENS finale, he explained this was the result of a ‘quick & messy pit stop and lets say a lot of fuel came out and the engine flame out was due to that.’

On going to Chile armed with the new Mugen Seriki MRX7, it three years to the month since he made the switch from then German brand Shepherd after a long stint to the Japanese manufacturer, Simon gave the upbeat reply, ‘Actually it was a great season for the new car.  I could use it since ENS Ettlingen so I have a lot of experience. Durability and everything is as Mugen always was.  I think we could make another step forward with the car in the last month before that I couldn’t spend too much time on the track practicing due to other reasons. We will also get so much practice in Chile I think we will improve the car even further.  There is a lot to discover still.’

Having not yet sampled the track (at the time of our chat), asked his thoughts from what he has seen he replied, ‘It looks like Fontana (2018 WC host track).  I think the grip level will be more suitable for me than it was in Fontana because that was super high grip.  The layout in Chile looks good, and fast, so I think it will make for a proper World Championship.’  On that note we can’t wait to follow how it all unfolds at the impressive CACH facility.

Red RC’s coverage from Chile, which is presented by Capricorn, Radbody, T-Works, and IFMAR, will start on Tuesday (Dec 2nd) with four rounds of seeding practice and continue through to Saturday’s title deciding 1-hour Main,.

1:8 Onroad World Championship coverage presented by Capricorn, Radbody, T-Works, and IFMAR

Having hit a landmark of telling the story of how 50 World Championships unfolded when we reported on Marcus Kaerup’s 1:10 4WD Buggy World title win in Australia, Red RC is excited to be travelling to Chile to cover the 1:8 Onroad World Championship, our coverage presented by Capricorn, Radbody, T-Works, and IFMAR.  As we kick off the first of our next 50 World Championships, this one is special because it was IFMAR’s original World Championship category that was also the first World Championship to be covered here on Red RC back in 2007 in Argentina.  With a certain Lamberto Collari racking up the 8th of his 9 World titles, now 18-years later the championship is back in South America and having missed the last one Red RC are definitely going this time round for what in our opinion is the Formula 1 of RC Racing.  Unfortunately while Collari and all of his team-mates at reigning World Champion manufacturer Infinity won’t be making the trip to the amazing CACH facility in Santiago, we are still going to be in for the intensity that only a World Championship brings out in drivers and manufacturers.  While Japan 2023 winner Dario Balestri doesn’t appear on the entry list, it is led by three World Champions – Simon Kurzbuch (2016 World Champion, Brazil), Shoki Takahata (2019 World Champion, USA) and Toni Gruber (1:8 GT 2023 World Champion, Australia) – they will face the next generation of potential World Champions in the form of drivers like Andrea Catanzani who unlike the three World Champions has been to the track previously where he was the Top Qualifier at the IFMAR 1:8 GT World Championships back in September.

Our coverage is only possible thanks to the support of our sponsors and a specialist manufacturer born out of Nitro Onroad racing, Capricorn and its owner Patrizio Rossi have been staunch supporters of the category so we are honoured that they came onboard for this the 24th running of the 1:8 Onroad Worlds which was the founding category for World Championship RC racing when it crowned its first Champion in 1977!  A company that has been instrumental in Red RC’s World Championship coverage post Covid, US body producer Radbody, as fans of all things fast and aerodynamic, are the third of our sponsors making the fourth & final stop on the 2025 World Championship World tour possible.  Long time supporters of Red RC, aftermarket parts and accessories producer T-Works need no introduction and we are delighted to team up with them once again after they supported us last year in attending the 1:10 Nitro Touring Car WC at Huge RC in Thailand.  Having dealt with them at each and every one of the previous 50 Worlds we’ve covered, they are the ones responsible for the race that awards the greatest prize in racing after all, we are very grateful to the World governing body IFMAR for their assistance in ensuring the race with the longest history records will get an in-dept 2025 chapter update!  Red RC’s coverage will begin on Tuesday with Seeding Practice and the Opening Ceremony before we quickly get down to the serious business of qualifying with it all culminating with the crowning of a new World Champion on Saturday (December 6th).

MonTech New York Grand Prix Chassis Focus Index

Last weekend Red RC returned stateside for the 7th edition of the MonTech New York Grand Prix at the 360V2 indoor track in New Rochelle.  One of the highlights on the annual US onroad racing calendar and having attended the Donny Lia organised event for the first time in 2024, this year attracted a strong international entry but there was little they could do about top US driver Sam Isaacs.  The US Champion would complete the double, winning both Modified 1:12 and Modified Touring Car for Awesomatix.  While Isaacs was testing new parts on his 1:12, meaning we couldn’t photograph the car for a Chassis Focus, we did get to feature his winning A800RR Touring Car.  The NYGP would see the US debut of Xray’s all new X4’26 and with just two examples of the Slovakian manufacturer’s latest touring car in the country we got to photograph both of them, one being the Stock car of NYGP first timer Jan Ratheisky and the other being the Modified example of US Team Manager Drew Ellis.  In 1:12 we got to feature cars from three different manufacturers including 2024 Champion Kemp Anderson’s Awesomatix, the CRC of returning former NYGP Champion Ollie Payne who made the trip over from the United Kingdom, and the latest Excelerate Prodigy 12 from the car’s designer Josh Cyrul.  Additionally we got to include the 25.5 LMH winning Express of Charles Bruno and the FWD class Xray of Top Qualifier Andy Brooks to complete our latest Chassis Focus Index.

Isaacs does the double at Montech NYGP

Having won 1:12 Modified, Awesomatix’s Sam Isaacs has gone on to complete the double at the 7th edition of the Montech NYGP by also winning Mod Touring Car at 360v2 in New Rochelle today.  Securing the TQ for the Speedzone Modified Touring Car class ahead of team-mates Kemp Anderson and first time NYGP visitor Lucas Urbain, the previous two time winner was the class of the field setting the fastest lap of the single 5-minute A-Main to win by just of 2-seconds from Anderson.  A further 1.3-seconds back Lucas Urbain made it another podium lock out for Awesomatix.  With Xray taking the win last year thanks to Keven Hebert, it was NYGP debutant Jan Ratheisky armed with the all new X4’26 who led their challenge this year finishing P4.  Also racing in the Jaco 21.5 Super Stock Touring class, the German would go one better finishing third, Craig Xavier’s Awesomatix taking the TQ & win ahead of the last year’s winner Eric Anderson.

Reacting to his win, Isaacs said, ‘It was a good race. I was able to keep it clean and the car felt pretty good maybe a little bit pushier than qualifying but a pretty safe race car so it worked out.’  With the win bring his NYGP wins tally to 6, the United State’s leading electric onroad racer said, ‘I felt like I was driving pretty well this weekend so I’ll try to keep it going especially into the Paved US National next week.’  On making the transition from NYGP carpet to the asphalt for the ROAR National Championships, the 31-year-old said, ‘It’s little difficult and it may take a practice run or two but that surface is complete different, a sealed lower to medium asphalt track, so it will definitely be an adjustment and then going from a climate controlled environment to something hot outdoors it will be tough too.  But this is definitely a nice win to have going into it.’

Coming out of the blocks looking very racy, Anderson said, ‘The car started off good and then just lost a bunch of grip so I didn’t have the pace to keep up with Sam.’  The 23-year-old, who also finished P2 in Touring Car last year, continued, ‘after that I just tried to circulate around and try and stay ahead of Lucas.’

Asked to sum up his first NYGP, Urbain said, ‘The main went alright, I guess according to plan. These two in front are quicker and I was quicker than Jan. I thought at some point I could make a bit of an impression on Kemp, he had a few bobbles here & there but I was never close enough.’  With the race marking his first ever US race on carpet, the Frenchman continued, ‘So yeah it was pretty much how it’s been the whole time, same gap, maybe a little bit close now I closed the gap very slightly.  I guess it unfinished business and we need to come back next year and do better I guess.’

Giving his reaction after the final, Ratheisky said, ‘The final was very good. I was happy to be able to follow Lucas for like two & a half minutes but it took too much risk to follow him so I decided to back off a little bit to finish 4th instead of sending my car to the wall again. I feel like our set-up work was going in the correct direction unfortunately the race is over right now but it’s a good start with the new car for sure.’  On his Super Stock podium, he said, ‘People who know me know I am a final driver and I was able to overtake EA but then unfortunately I hit a curb and made a light roll and I was not able to recover to be able to attack again so I secured the third instead of maybe throwing it away.’  A regular visitor to US races, asked his thoughts on his first NYGP, he replied, ‘Amazing. It is also the most exhausting race also because you have almost unlimited practice runs which is great but very very challenging on the body.  I don’t remember the last time I went to bed that I wasn’t able to think about anything as I immediately feel asleep.  I would love to come back, it’s a really good race.’

Class Winners Round Up

With a total of 9 class wins up for grabs at the MonTech NYGP, in 1:12 Stock by CRC it was British visitor Morgan Williams and his CRC who took the win as the Top Qualifier.  Behind him Jeff Dayger and Fabio Evangelista completed the podium.  In 25.5 Stock Touring by Snag RC the win went to pole sitter Andy Brooks while the 21.5 LMH12R by TQ Wire victor was Joe Wright.   The 1up Racing sponsored FWD class saw Michael Skeen take the win from 3rd on the grid with Top Qualifier Andy Brooks second and Esse Castro third.  From the pole Charles Bruno won the 25.5 LMH by Interstate Hobby Sport from Charles Edwards and Dan Arnold.

Isaacs claims third NYGP 1:12 Mod win

From a grid that was lead out by the past three 1:12 Modified Champions of the Montech New York Grand Prix, it was the high profile East Coast race’s most successful driver Sam Isaacs who took the big win at the 7th edition of the 360v2 hosted event.  Starting P2 on the grid behind 2021 Champion Donny Lia, and in front of defending Champion Kemp Anderson, while Isaacs mounted a number of charges on Lia over the 8-minutes it was a backmarker that ultimately decided the race.  Running as an impressive high speed train for over 6-minutes, CRC’s Ollie Payne also in the mix, Lia’s efforts would come undone when he collected a back marker who was out of shape having just launched his car off the curbing.  With Isaacs and Anderson going through, Lia would set about a charge getting back by Anderson but running out of time to deny Isaacs his 3rd win in the AbsoluteHobbyz 1:12 Modified class, the final gap 0.885.  Anderson would complete the podium in New Rochelle with 2019 Champion Payne claiming fourth on his NYGP return while Excelerate’s Josh Cyrul round of the Top 5.

Reacting this his win, the NYGP one of favourites events, Isaacs said ‘It was a pretty cool 4 car freight train for a while and I think Donny was just getting used to his car and then the pace started to pick. I had a couple of spots at the beginning where I though maybe I could get by him but it probably wasn’t worth trying it if it wasn’t going to be for sure clean.’  The 31-year-old, who won his latest National title here earlier in the year, continued, ‘The last minute & a half we were going around about the same distance we were but unfortunately he got caught up in traffic and I was just able to go a round that. It would have been nice to race to the end, I feel bad that that happened for him but unfortunately that’s how it goes sometimes in 1:12 Mod racing.’

‘It’s part of racing, shit happens, what are you going to do’, was how Lia summed up the unfortunate incident.  The man responsible for putting on the NYGP, he continued, ‘I had good race and I am glad everyone is here and that really all that matters. If I do well at this race every race that’s just a little bit of a bonus.’  On his race up to the incident, Lia said, ‘I was just maintaining the gap, kind of cruising and maintaining the gap to second and then when that happened it was a little too late in the race to really make up any time.’  Asked about the charges from Isaacs, the two World Championship finalist said, ‘that’s kind of 12th scale Mod racing.  It’s so hard to push hard all the time but you can make runs. When you are leading it’s hard to push hard so when you are leading you just want to maintain. Sam was going to push hard and put pressure on me to try and make a mistake and he was trying and I did clip a couple of curbs. We raced well and clean just wish we could have raced it out you know. I had a little left in the tank, there was no need to push too hard. Every time Sam made a run and put pressure on me I would respond. I guess shit happens. What happened was with a good friend of mine, he is more upset than I am, it is what it is, I don’t care.’  Starting P2 in the Excelerate RC 1:12 Super Stock class as the defending Champion, unfortunately Lia’s day didn’t get any better as a mistake led to multiple impacts and a body that needed to be popped back into shape and he finished 6th.

Asked about his final,  Anderson said, ‘It was a really good race, Top 4 nose to tall most of the race, my car was pretty good and I was having to lift a little bit. At the end Donny got collected by some traffic and I made one mistake after that that let him get back by.’  On his podium result, the World Championship Top Qualifier said, ‘3rd is not too bad, I’m happy. A podium lock out again for Awesomatix so it’s pretty good.’

On his 4th place finish in 1:12 Mod, Payne said, ‘the car was a little but pushy so I couldn’t quite stay on the pace of the front guys but the car was pretty consistent I was just missing a little bit of steering’.  Also competing in the Excelerate RC 1:12 Super Stock class, the British driver would dominate proceedings.  Taking the TQ he would win the final by a comfortable 2.5-seconds over 1:12 Spec World Champion Max Mächler and Jeff Dayger completing the podium.  On his performance the European & British Spec Champion said, ‘It’s been pretty much perfect the whole way through, there is nothing much I would change about it if I was to do it again.  In the Main obviously Donny had that issue and as soon as that happened I just settled down and just gave myself a foot everywhere to just finish.  It couldn’t have been much better.’
