Senna’s ‘private kart mechanic’ Tche reveals the secret to his speed


Posted on

In March 2009 I advised a friend in Sydney that my wife and I would be in the city and surrounds ahead of travelling to Melbourne for the grand prix. Not only would we be most welcome to visit, said my mate Patrick Wedes, but would I be interested in interviewing Lucio Pascual Gascon, aka Tche, Ayrton Senna’s karting mechanic?

I let Patrick sweat for a micro-second before taking up his unexpected offer. It turned out one of the late driver’s staff members was marrying a Perth-based mate of Patrick’s, and she had asked Tche to do honours at the wedding. Patrick asked her whether he would be prepared to do an interview, with her acting as Portuguese/English translator – to which both kindly agreed.

The only mutually convenient time for all was early on the Sunday morning, when we’d be in a bed-and-breakfast in the Blue Mountains area. This meant conducting the interview over a flaky dial-up modem connection.

Nonetheless it yielded the most emotional yet insightful interview I’ve ever conducted – and likely ever will – despite major linguistic and technical challenges. These included the connection repeatedly dropping out, and every question being posed in English, translated into Portuguese, with the response following the reverse process. In addition, due to the language barrier, various questions or answers needed additional clarification.

We’d originally scheduled 20 minutes, but ultimately the process ran to 90, with Tche taking numerous breaks to compose himself. At one stage I apologised for posing searching questions that clearly delved into areas of deep and raw emotional pain. All credit to Tche: Where he could so easily have ducked out, he went the full distance despite the obvious distress.

So special was the end result that I decided to hold back for a special occasion, rather than publishing it randomly. The 25th anniversary of Ayrton’s untimely and tragic death provides that moment.

Ayrton Senna
Senna didn’t appreciate Tche’s advice to begin with
Lucio Pascual Gascon has never forgotten the day a young teenage karter named Ayrton Senna da Silva arrived at his Sao Paulo workshop.

Gascon, known to everyone in the local karting scene as Tche, mentored upcoming racers on driving technique and car engineering. But that day tragedy had struck: One of his student had been killed in a road car accident.

A decade earlier, Emerson Fittipaldi had turned to Tche to prepare his karts in his first steps towards two world championships. Fittipaldi’s success had put the nearby Interlagos circuit on the world championship calendar.

Senna would go on to outstrip Fittipaldi’s achievements and become, in the eyes of many, the world’s greatest Formula 1 driver. But his relationship with Tche became a point of conflict with Senna’s family. Following his death in the 1994 San Marino Grand Prix, 25 years ago today, some in the Senna family wanted Tche barred from his funeral.

Speaking in an exclusive interview for this website Tche, who mentored Senna throughout his karting career, gave rare insight into the formative years of the sport’s most revered driver. Starting with the day Senna turned up in his garage carrying a broken kart engine.

“He brought the engine in,” Tche explains through a translator. “It was broken, and I fixed the engine. It was [done] very fast and very cheap. “But I had an argument with Mr Milton, Ayrton’s father, because it was so cheap – and usually what is too cheap is not good.”

Tche was held in high regard by the local karting community, but this first encounter with the Senna family got their relationship gave a hint of the troubles to come between them. “It caused a little problem between us,” he admits.

Among the other drivers, Tche’s services were in high demand. “I was a mechanic for 15 years before I met Ayrton. All the drivers wanted me to do their engine with him so he had to find a specific hour to receive Ayrton.”

In addition to repairing and fine-tuning their engines, Tche helped the young drivers fine-tune their racecraft. “I used to teach the boys how to drive correctly. The fathers didn’t like a lot of this kind of advice or teaching or guidance.”

This wasn’t only true of Senna’s father. The young champion also initially resisted Tche’s teaching. “When we went to the track – me, Senna and his father – I started correcting the way he used to drive, giving him some tips how to drive better and how the engine worked. Ayrton himself didn’t like much and his father even less.”

However Senna was persuaded of the value of Tche’s input the first time he put it into practice. At the Interlagos go-kart track which is now named after him, Senna claimed his first major victory.

“Senna decided to follow my guidance. He won the race, the first race. So although he didn’t like what I taught, Ayrton realised that he should follow my advice, as he won the race.”

The relationship between the two was vital to Senna’s early development as a racing driver. He began to call Tche his ‘private mechanic’. Other times they referred to each other as ‘Tche and 42’, in reference to Senna’s kart number.

But Tche’s services were in demand from other drivers as well, who became suspicious that Tche was supplying Senna with superior engines.

Senna’s rivals wrongly suspected he had superior engines
“Many people used to challenge me and Ayrton because they thought that I was always protecting him somehow. Many times I said it’s not only the engine – I had to repeat this many times – it’s also the driver.

“So what we had to do many times is disassemble Ayrton’s engine and lend it to someone so they could test. Because they thought if they had Ayrton’s engine they would win the race. And they proved it was not true because whenever they lent the engine, many times they failed and they lost the race.”

Another of Tche’s ruses was to give drivers the impression they had in fact been given a ‘Senna special’.

“[I would] get the engine the engine – not Ayrton’s but the other boy’s – and just change one piece and put Ayrton’s name on it and give the same engine back to the driver.

“But they were the same engines. It was not Ayrton’s. Just because it had ‘Ayrton Senna’ on the engine it made a huge difference because they thought they were driving the engine that Ayrton had driven before. Then the boys who were driving what they thought was his engine said ‘this engine is much better’. In fact was their own engines just with a different name.”

In Tche’s eyes what set Senna apart from his rivals was not special hardware, nor innate natural talent, but a fearsome work ethic.

“It was not just a gift,” he states. “It was training, training, training and training again.

“The difference between Ayrton and the other pilots is that he just trained. All his life he was there, training. And the others, they were not as focused.

“He was a boy at that time. And while the others were flirting, or going to a shopping centre, or whatever they used to drive a kart just as a hobby, Ayrton was there in his workshop with me assembling and disassembling the engines and training, training, training. He was one hundred percent focused.”

And when Senna tasted defeat, he redoubled his efforts. Tche tells the story of how Senna reacted to losing a race in the rain – the very kind of conditions he later became known for his mastery of.

“He had a very important race in Sao Paulo. it was raining that day and he lost the race [to] a friend of his. He [spun] the kart three times, looping three times.

“His friend who won the race came to him and he was joking about he’d lost. And Ayrton got really pissed off.

“Then what he did was Ayrton just stopped going to school and he started training even more. He said that it would never happen again. So he trained instead of eight hours he started doing 15, 16 hours a day in any weather: wet, raining. That’s why he developed his ability to [drive] in the wet.

“As he trained a lot he learned how to drive in wet, dry, hot, cold, whatever it was. Even under a storm. He was not lazy at all.”

Tche was increasingly bankrolling Senna’s karting career. “He used four engines a day. He used the first for an hour and take it off, put another one. He never broke engines, it was just using for an hour, taking it out, putting the other one. So four engines a day like that.”

As Senna pounded around the track, he wore his way through three sets of tyres a day, another bill Tche picked up.

But as Senna lifted his sights higher and prepared for the move to Europe which would put him on course to become Brazil’s third world champion, the rift between Tche and the Senna family only grew. Tche believes Milton grew jealous of the closeness of their relationship, that Senna came to regard him as a kind of ‘second father’.

“I have four sons. Ayrton was like a son to me, I always said that I had five sons. When Ayrton started winning a lot of races we got closer and closer.”

But that “caused many problems with the family”, said Tche. “Especially with Mr Milton.”

Following his crash on May 1st, 1994, Senna’s body was returned to Brazil. Three days of national mourning were declared.

Tche went to the funeral, on May 4th, but was met with an unwelcoming response.

“I he had to fight, to argue to get in,” he said, “because they didn’t want me to be inside.”

This final recollection proves too much. Tche’s voice falters and trails off. Our translator interjects: “Can you please just give him a minute, because he’s a bit emotional…”

    Lovely story, thank you. Anyone who was watching this day 25 years ago remembers where they were. At the time with news bulletins being once or twice a day and of course no internet, although there was great sadness, especially in his native Brazil, outside the motor racing community and i include fans in that, it seemed to quickly fade. Of course the mind plays tricks on you over 25 years but he is perhaps more talked about now then ever before.

    I saw every race he entered in F1 and although my brother was a huge fan of his, and therefore I wasn’t (kids are stupid), I’m probably more sad today that he is gone than i was then.

  2. WOW. Work ethic of a champion.

  3. Aryton Senna. He replicate what Napoleon Hill said in his book “Think and Grow rich”.

    “Whatever the mind of man can conceive and believe, it can achieve.”
    “Strength and growth come only through continuous effort and struggle.”
    – Napoleon Hill

    Everyone can do it. Everyone can develop their own gift if they continuously improving himself beyond what people can imagine. Michael Jordan practice and fail daily to become a successful basketball player of all time.

    Aryton Senna fail many times when he was young. He practice everyday. He practice more than anyone. That’s why he is the GOAT.

    My father was lucky enough to be the dedicated engineer to look after Senna’s NSX in Brazil, the black one.

    Recently my dad was preping for a helicopter flight when he heard on the radio that an Agusta was coming to the heliport. As soon as he laid eyes on the Helicopter he said that’s Senna’s family’s Helicopter and a few minutes later his dad walked out and by chance their eyes met. Mr. Milton didn’t think twice, he came over to us greeted my father and said that the car was still there but needed a new clutch. My dad is already retired but he said no worries, let’s order the parts and get someone over there.

    It was just surreal.

  5. These kind of stories are the greatest inspiration. Talent is nothing with the utmost dedication and work ethic. Nobody gets successful in anything with just the talent.

    Thank you Dieter, great stuff!

    RIP Ayrton

  6. This is a great piece. And it makes total sense of course. Training a skill to the peaks of a Senna requires an obsessive dedication, hours of trial and error, and a lot of personal sacrifice, but eventually becomes so instilled in the person that it appears second nature. Thanks for sharing the interview.

    1. *Tens of thousands of hours!

  7. That’s alot of hours.

  8. “But Tche’s services were in demand from other drivers as well, who became suspicious that Tche was supplying Senna with superior engines.”

    Haven’t we heard that from someone else😁😁😁😁

    Great article, thanks!

    1. The more things change, the more they stay the same.

      Honda should’ve used that trick and put a “Senna” sticker on Prost’s engine.

  9. Great an very insightful article Dieter! I remember when Senna started to practice at Interlagos karting circuit his times weren’t great, and when he focused on improving his times, the results were inconsistent, as whereas we got right in a corner, he missed the best line in another and therefore he was inconsistent on his lap times. With the advice from Tchê, he changed his way of practicing on the track. He mentally divided the track in 4 sectors, and he spent a whole morning focusing on first sector, and not paying attention on the other 3 Sectors, until he nailed the first one. On the afternoon he did the same process, this time focusing on sector 2 only. And he repeated this process, until the best lines were fully memorized in his brain. That way he improved massively on times and became a master of this circuit. Also, as said by Tchê, his neighbours joked between them every time it started to rain at Interlagos; they knew that once the first raindrops would start falling , they would see Senna running to get to the track and practice driving on wet conditions. That shows his enormous commitment in self improvement. This is what made him a great champion.

    1. @mmertens: Thank You, very inspiring to read about. Whatever Your profession in life is, You can learn from this: Focus on learning step by step, always training to become better.

      1. You’re welcome, and your totally right about it. Focus and dedication is everything.

  10. Dieter it’s Patrick Wedes you write really well as you do.

    We miss Tche, the time in our home in Sydney for two weeks and the appearance in The Motorsport Shop was epic.

    The story of when he restored one of Ayrton’s Kart engines is another for another day.

    Ayrton will never be forgotten.
