Polito tops seeding at SIGP in China

Sworkz’s Mattia Polito is the top seed at the SIGP Offroad Race in Xiamen, the Italian fastest in both Nitro and Electric Buggy on the return of China’s biggest annual offroad race after a 5-year break.  Over 3-consecutive laps of the challenging 3-Circles track, overnight repairs making for improved conditions for today’s two seeding rounds, Polito would go fastest in both ahead of Xray’s Bruno Coelho.  It was however the first round that was the fastest for the 21-year-old who had 1.6-seconds on Coelho.  With Coelho’s fastest time coming from CP2, the margin on that occasion was down to 2/10ths of a second as Polito’s best was 7/10ths slower than his earlier attempt.  Behind Davide Ronnefalk took his Xray to the 3rd fastest time with his CP1 time ahead of Davide Ongaro, the reigning World Champion improving by over a 1-second in CP2.  WIRC’s Gabriel Astorino and Mayako’s Joseph Quaqraine completed the Top 6.

With this his first visit to the SIGP, Polito was pleased with his performance in seeding describing it as ‘pretty good’.  The 2021 Italian National Champion is also liking the track layout if not the surface adding ‘it’s bumpy but the racing line I like.’   Switching to a different Matrix tyre for the second practice run, he said, ‘It was not fast like the previous one so we go back for the first quali’.   Having been Ongaro’s main title challenger in the Italian National Championship the last 3-seasons, looking towards qualifying he said he confident that he can transfer his seeding pace to a consistent 7-minute qualifier.

Summing up his seeding performance as ‘pretty good’, Coelho added, ‘we are still trying some tyres.  The car is working pretty good now so we are just trying to find out the tyres.  In the morning the track is a bit wet and during the day it starts to become drier and the compounds change completely the grip.  I was changing the tyres during the run and at the end I was able to run 3 pretty good laps’.  Using Hotrace’s Bangkok tyre, he said ‘from super soft to medium it works pretty ok depending on the time of the day so we need to find the best solutions for this.’  Having admitted yesterday that the track was challenging he feels, ‘today seems to be easier to drive than yesterday, I think they fixed some jumps which was the biggest trouble yesterday, this has made it was drivable and more, lets say more, racing that before.’

His first Nitro Buggy race since the World Championship in Redovan, Ronnefalk said, ‘I tried tyres in both rounds, the first round I came into pit and tried different compounds, I ended up liking the second one better which was the (Hotrace) Bangkok Super Soft.  Then for the last one I decided to try something else on the tyres, a different compound again just to see because we don’t have a lot of tyres between Bruno and myself.  We have to make sure we have enough for the whole race.  So I just checked how another one felt but in the 2nd seeding is was not really working well.  The car felt good and everything but I had no lap time speed cause I had not traction.  The car was been feeling good today after some changes this morning.’   Asked if he noticed the track repairs, the Swede said, ‘the first couple of runs in the morning has always been nicer than the last few, it seems the grip is a little higher in the morning when the track is a bit damp but as soon as it dries out those small little bumps get sharper again and its difficult towards the afternoon to drive.’   Looking to Q1, having taken the opening eBuggy qualifier, he explained, ‘I was able to TQ eBuggy and I am running the same set-up on both cars so it is just a matter of collecting data we have had so far from all our tyres tests because it looks like the tyre is making the most difference out there, of course the shock package and everything is important but the track gets kind of polished after lunch so then you have a lot less grip than in the morning.’

Without out his father as his pitman this weekend, former World Champion Adrien Bertin filling that role here, Ongaro said, ‘We struggled a little bit with the set-up compared to two days ago.  We started with a good base but then after one practice the car start to make strange things so we struggle a lot with the set-up.’   Second fastest in the opening eBuggy qualifier, he continued, ‘Now we change for the eBuggy and it seems like the car was really really better, I feel I can push so I will put the same setting on my nitro for Q1 and see if that makes he difference.  If yes we start from that point again.  I think now changing a few small things makes a huge difference, the consistency was much better than before.’

Sahashi title defence back on in Thailand

Tadahiko Sahashi’s 1:10 Nitro World Championship title defence is back on with the Infinity driver booking his place in final at Huge RC Circuit after finishing second to team-mate Dario Balestri in the second of the two Semi Finals.  Having topped seeding, Sahashi then struggled throughout qualifying and found himself scrapping his way onto the back of a direct spot in the Semis.  In the early stages of the final it looked like the Japanese driver’s quest to become the first back to back Champion of the class was over, however by the 10-minute he was up to third, helped in part by 2012 Champion Meen Vejrak and Takaaki Shimo both running out of fuel.  Up front a flip by pole sitter Balestri allowed Chavit Saligupta to lead but shortly after third way distance his car came to a permanent stop ending his hopes of repeating his 2022 final appearance.  Looking like he was safely into the final as he lapped in 3rd position there was a heartbreak for Australian Jessie Davis.  With three minutes to go and having just exited pit lane his car came to a stop and with his engine refusing to restart his Worlds was done.  Capricorn’s Thilo Diekman would finish 3rd to book the German’s first World Final start.  In the other Semi, Naoto Matsukura looked like he was out for a Sunday drive, the 2018 World Champion lapping the entire field with a flawless drive that has the Infinity driver highly motivated for the final.  Having started on pole, Capricorn’s Toni Gruber came home 2nd as he continues to challenge the might of Infinity here in Bangkok but the 1:8 GT World Champion admitted himself that his Semi performance was not a Title contending performance and they need to improve for the final.  On the road it would be Viktor Wilck that would complete the Top 3 but his car would be deemed to be too wide in post race technical inspection and Charlee Phutiyothin was promoted to the final.  The final two places on the grid would be decided on fastest times which went to Milan Holthuis and Sinnosuke Yokoyama.

Reacting to his Semi Final, finishing 2.6 seconds behind Balestri, Sahashi said, ‘I am happy.  Qualifying was not good but now I am back.’  One of only two drivers to hold nitro onroad titles in both 1:8 and 1:10, asked about tyre wear he replied, ‘After 30-minute there was nothing left so the car had understeer and no traction in the rear so w must make one change in the final.’  On making changes to his car for the title decider, for which he will start P5, he plans to change the rear wing saying he feels a little less wing will give him a better car.

Summing up his race, reigning European Champion Balestri said, ‘It was super safe with the set-up, engine, carburetion set-up so we try to make something more for the final.  It all went to planned, maybe a little too safe, but the point was to arrive at end and get into the final.’  A driver capable of becoming the first reigning 1:8 Onroad World Champion to also hold the 1:10 Title, the Italian said, ‘everything is on the limit here so we need to have an easy set-up on the car and engine set-up for a long final.’

‘I just drove around and did my own race.  Today my car is very nice, I am so excited for the final’, was Matsukura’s reaction to his dominant Semi performance which as the fastest of the two encounters will see him line-up P3 behind Top Qualifier Teemu Leino and Super Pole winner Jilles Groskamp.  Describing himself as ‘relaxed driving’ in the Semi, the only driver to be both a nitro and electric Touring Car World Champion said, ‘I hope I can do the same in the final and carry that momentum.’  Planning no changes for the final, on tyre wear he said, ‘I think the tyre is still OK (after 30-minutes) for me and my car was driving OK at the end but we need to check for the final.’  Impressed by his diver’s performance, master of World Championship winning pit crews Masayuki Miura described Matsukura as driving the Semi like it ‘was just a practice run.’

Asked about his Semi performance, Gruber said, ‘In the beginning we lacked a bit of steering because of the fresh tyres, in then in the middle of race the tyre was there but then it was critical to flip and I flipped one time.  After that I took it a little easier to not flip again but overall the feeling of the car today is not so good, also the engine was a little too rich and that effected the shifting in the infield.  Sometimes it change gear, sometimes it didn’t and that effected my driving and my confidence’.  Asked about changes for the final, the German said, ‘We will change some very small things built not much, 1-hour is a completely new and different race.’
