Vittorio Viglietti has already celebrated victories at Vallelunga and Mugello in his first GT3 season in the Italian GT Championship (CIGT). Much of his preparation, however, happened before he ever climbed into a racing car. The Italian talks through how sim racing helped him get up to speed, what changed when he moved from Lamborghini to Audi, and where he hopes his next steps will take him.
Returning to Mugello for the season finale of Italian GT brings brought back a good memory for Viglietti. In July, he and Marco Cassarà took their #22 Tresor Attempto Racing Audi R8 LMS GT3 to victory in the Am class during the Sprint weekend. After finishing fourth in class in the opening race, the pair won the second, with Viglietti making up ground during the final stint.
“It was much hotter than now, really hot. But it was a good race. We did a good job,” the 22-year-old tells GT REPORT in Mugello. “It was a class win, but still, in Am we did a good job recovering a lot of positions. So it’s a good memory for me.”
Mugello was one of two particularly rewarding weekends in his first year with the Audi. The other came closer to home, when he and Cassarà won their class in the second Sprint race at Vallelunga: “The highlights, I would say, were the win with Marco in Vallelunga – it’s my home track, so it was really nice – and also here in Mugello.”
Finding his way through sim racing
Viglietti was already racing in karts from an early age. His early career was interrupted, though, and it was through sim racing that he later found a way to pursue motorsport more seriously. He began in 2021 and was competing in ACI Esport Italian championships the following year. At DSC Vallelunga, the simulation centre inside the circuit, he developed his skills and later became an instructor.
“I didn’t do a lot of karting. My background is mainly sim racing,” he explains. “I think the main advantage I had was how fast I could adapt. In sim racing, you have a lot of time to try things. Before the races, you can do as many hours as you want. So when you get into the car, you’re quite ready. Not a hundred percent, because the sim doesn’t give you the real feeling.”
For Viglietti, the benefit becomes obvious during those first laps in an unfamiliar car. Having worked through similar situations on a simulator gives him a starting point when track time is limited. “The difference between me and someone who hasn’t done sim racing is that I can maybe reach the same lap time in a shorter time. I think that’s one of the advantages,” he points out.
There is more to that preparation than learning a circuit. Experimenting with the technology also helped him understand what to look for when driving. “You can change the weather, the conditions, the grip, the setup. So you also learn how to work on the car, changing parameters,” he says.”
“I think it’s a good school for racing. If you do sim racing, it’s a whole ecosystem. You can do everything. You can develop a good feel.”
The Audi is ‘a whole different beast’
Viglietti returned to kart racing in 2024, taking a win and fourth in the IRK Promotion by TBkart championship. That year also brought an appearance in the FX Series at Vallelunga, where he claimed pole, a win and a second place in a Griiip G1. Testing with DL Racing then opened the way to a full Italian GT campaign in a Lamborghini Huracán Super Trofeo.
He finished 2025 as runner-up in the GT Cup Division 1 Pro-Am Sprint standings. “I found the Super Trofeo really fun. With my teammates last year, we achieved some good results,” he says. “It was my first year, so it was quite a surprise!” A welcome surprise nevertheless, and one that put his racing skills and intelligence further in a spotlight.
It resulted in a step his first GT3 season. Moving to the Audi run by Tresor Attempto Racing for 2026 brought another learning process. Although both cars – the Lamborghini and the Audi – are familiar sights in the Italian GT paddock, the change involved much more than getting comfortable with a different badge.
“I could feel the change because last year I was racing the Super Trofeo, which is a GT Cup car. It’s a completely different concept,” Viglietti explains. “It’s not a road car, but it’s closer to a road car. This one is completely the opposite. I think this car only keeps the Audi logo from the road version!”
The Audi R8, carrying one of the oldest GT3 platforms, required him to develop his understanding of how to use the car’s aerodynamics. “It’s a whole different beast. I needed to adapt to working with aerodynamics, the suspension, the brakes and everything else,” he continues. “But GT3 is GT3. Everybody knows it. It was good news to become part of this team and drive this car.”
The class victories at Vallelunga and Mugello gave him results to take from that first season, even if his programmes did not always run smoothly. “In the Endurance series, we didn’t have a lot of luck,” he says. “In Sprint, I missed one of the races, so I couldn’t really fight for the championship. But still, in the last race, we were almost there.”
Aiming for GT World Challenge
By the time of his conversation with GT REPORT at Mugello, Viglietti had not settled his plans for the following season. He does have a goal of where he would eventually like to race. After progressing from sim racing to GT Cup and then GT3, GT World Challenge Europe is the championship he hopes to reach. “The objective is to go to GT World Challenge one day,” Viglietti says. “Even more now than before, because it’s a really nice championship, with a lot of big names coming in. It would be cool.
“I don’t mind whether it’s Endurance or Sprint. I can do either! That would be really nice.”
