Kurzbuch cruises back into contention in Chile with Semi win

Having missed out on a Top 4 direct to final qualifying position as he ended P5 at the end of the 6-rounds, Mugen Seiki’s Simon Kurzbuch has put himself back in contention for a second IFMAR 1:8 Onroad World Championship title by cruising to victory in his Semi final this morning in Chile.  Winner of the World title in Brazil in 2015, a decade on the Swiss racer returned to South America as one of the pre-race favourites but on arriving at the CACH track in Santiago he struggled to find his true form.  Leading away the second of the half hour Semis, Kurzbuch drove a calculated race with his crew executing a swift tyre change en-route to him winning by over a lap from the similar car of Britian’s Alex Thurston who together with third placed finisher Christope Louis progresses to their first World Championship final.  The 24th running of IFMAR’s original World Championship, the first of the Semi Finals woulds see 15-year-old German driver Leon Fuhrmann head a Capricorn 1-2 from team-mate Thilo Diekmann, the separation 4.7-seconds at the finish.  In third, a driver who needed the Last Chance Qualifier race to make Main here at the 1:8 GT Worlds back in September, Brazil’s Flavio Elias booked himself another 1:8 Onroad Worlds final appearance after recovering from a plug change during one of his pit stops to overtake leading Shepherd driver Tim Wood for the bump up position.  Wood however would take the win in a very close finish to the 15-minute LCQ, 2/10ths of a second ahead of a Ricardo Hofmeijer, to become the 11th car on the grid and make it five different manufacturers in the final.

Giving his eeaction to his Semi Final performance, Kurzbuch said, ‘The car was feeling good and everything went to plan and we are in the final, we are happy about this but there are still a few things to figure out to be more competitive.’  Asked how the track is today, yesterday a day off for the top drivers, the 33-year-old said, ‘It was good.  I like the cool conditions as it is more suitable for my car.’  Changing all four tyres in the Semi asked his opinion on tyre wear he replied while laughing, ‘I don’t tell you know’ before continuing, ‘but we were able to find out what we wanted to know in race pace.  It will be interesting.’

A driver whose focus this season has been on 1:10 Nitro Touring, finishing 5th overall in the ENS, but now making the full time switch to 1:8, summing him his Semi win a very pleased Fuhrmann said, ‘At the beginning it was not so good but from the middle of the race the tyres had more grip and then I had more steering.  The car was good and could hold (position) with my team-mate Thilo Diekmann.’  A driver who opted not to change tyres over the 30-minutes, and setting the fastest lap of the race with Kurzbuch the only other driver to better that time, asked his thoughts on what will be his first World Final and first time racing for 1-hour, he replied, ‘I think 1-hour will be very difficult so I will just go out and drive my own race and try to make no mistakes.’

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.
