Deja vu! Catanzani is Top Qualifier in Chile again

It was a case of Deja Vu at the IFMAR 1:8 Onroad World Championship in Chile today as Serpent’s Andrea Cantanzani claimed his second overall Worlds TQ of 2025 in the sixth & final round of qualifying, the super quick Italian having pulled off the same feat 11 weeks ago to the day when he was Top Qualifier at the 1:8 GT Worlds.  With Catanzani equalling Maxine Ripoll with a second TQ run of the event in Q5, this set the stage for a thrilling duel between the two young guns.  The highly anticipate battle however wouldn’t go the full distance.  Steeling time from his rivals with his super quick fuel stops to TQ Rounds 3 & 4, unfortunately this time round Ripoll would have issues in pit lane, his engine flaming out during refuelling.  This ended what has been a super impressive and entertaining to follow challenge from the 19-year-old for the top spot on grid.  With Ripoll out, Catanzani would TQ the round ahead of Capricorn’s Toni Gruber and Mugen Seiki’s Shoki Takahata to secure the overall TQ, the first in a long long time for 1:8 Onroad pioneering manufacturer Serpent.  For Gruber and Takahata the result will see them go directly to the final as Top 4 qualifiers.  One of the favourites ahead of championship, Simon Kurzbuch would end quali with a P4 which wouldn’t be enough and now the 2015 World Champion has a Semi final between him and lining up to try and claim a second World title.

One his Q6 run Catanani said, ‘it was really good but difficult with the wind, the final 4-5 laps the wind came really hard and it was difficult to drive but I managed it well so I am really happy.’  He continued, ‘I’m sorry for Maxime that he flamed out because I think it would have been very close in the quali but yes I am very happy get the TQ.’  On his second Worlds TQ in one year, unfortunately the 1:8 GT Worlds Final not going way after an early engine flame out, the 20-year-old said, ‘I hope that now it will be good for the race,’  Asked what he felt would be the biggest factor for Saturday’s 1-hour final he said, ‘we have to check all the tyre wear on the old sets that we have and then we will make a strategy but I think the most important thing for a 1-hour final is to be consistent and no errors.  It will be hard but I hope that we will do a good job.’  On car set-up he said in general there is no need to change the car for the longer run however he said they may try something in the Top 4 practice session but emphasised it would not be something to different to what they already have.  He concluded, ‘I think the car is really fast and really good and also really easy to drive and in these conditions this is the most important thing.’

Clearly disappointed at missing out on the TQ, on the final qualifier Ripoll said, ‘I had a mistake just before the refuelling and when we make the refuelling the engine stop and so it was finished.  Still P2, and for the final it is good and I will fight for the win.  It is a long race 1-hour so anything can happen even the guy who starts in 10th can win.’  Having never raced a 1-hour final before, the European Championships a 45-minute main, asked if he has thought about his strategy for the final yet he said, ‘We will have tomorrow the whole day to prepare the car and prepare the strategy.’  Putting it to him that he was obviously disappoint to miss the TQ having been right in the hunt but that he is still in his first World final, Ripoll replied, ‘yes I know but when you almost get the TQ and you lose it at the end its a bit disappointing but in 1-hour it will be OK and I will be happy but for the moment it’s tough.’

‘The overall of the TQ was gone so then it was to make Top 4 so the final qualifier was perfect in that way.  It’s good’, that was how Gruber summed up the final qualifier.  Asked his thoughts on the upcoming final, the 2023 runner-up said, ‘I heard that maybe it is a rain day on Saturday, maybe then the grip and track will change completely after the rain.  If it doesn’t rain the track is pretty consistent, if it’s windy, if it’s hot we know how our car works but I think we might have to make something little on the set-up because when the wind was strong it was overall too loose.’  On tyre wear and the number of changes he expects to make, the German replied, ‘I think for everybody it has to be two times full.  Other strategies with tyres makes no sense.  It is strange because in both sides the wear is almost the same.  Of course the left is more tyre wear because of the big right corner but you also have a lot of tyre wear in the front right because of the left corner in the middle.  So it makes no sense to make half (change) because in the end the tyre gets too small and also that makes the car completely difficult and even more with the strong wind, you cannot drive like this.’  With tomorrow (Friday) a car prep day he will use the down time to consider his game plan for the final.

The fourth & final driver securing a direct spot in the final just ahead of his team Kurzbuch, Takahata said his car had ‘no pace’ in the final qualifying round, something that is a little concerning giving it ran at a similar time of day to when the final is scheduled.  Making changes to the car after improving it for Q5, he said the latest change didn’t work.  Asked it his thoughts on the final, the 2019 World Champion’s response was very clear, ‘I want more speed.’  Asked if going back to his Q5 set-up would make him more competitive, he said they need to find something more.  A driver who was in regular contention yesterday but hampered by driver errors, he said today that speed has just disappeared.  The 31-year-old hopes they can come up with some ideas to test in Top 4 practice session.

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,.
