Test Day Brno 2026 – GT & Formula at the Automotodrom Brno before the Masaryk Racing Days

Automotodrom Brno, Czech Republic · 27 August 2026 · GT and formula groups, max. 28 cars each

The plan is set

On 27 August 2026 we return to the Automotodrom Brno — and this time we're bringing two groups at once. Two weeks before the race weekend of the Masaryk Racing Days, we open the pit lane at the Masaryk Circuit in Brno to GT race cars and formula cars. Separate sessions, separate groups, one track — and all on asphalt that was completely resurfaced in 2025.

Whether you still want to fine-tune a setup, explore the track limits or simply need to rack up kilometres: this day is made for it. Open track. Maximum testing time. No race pressure.

Fresh asphalt. Open track. If you love speed, you'll feel right at home here.

TWENTYSEVEN Trackdays

GT & formula under one roof

We organise the day as two separate groups — one for GT race cars, one for formula cars. Both groups run with a strict Open Pitlane concept and are each limited to a maximum of 28 cars. More cars mean more traffic and less testing time. We want neither.

GT group

For TCR up to GT3 — including all cup and trophy cars from the major brands.

• GT3 / GT4
• TCR
• Porsche Cup / Challenge
• Ferrari Challenge
• Lamborghini Supertrofeo
• & more

Formula group

For formula race cars from all currently active series — also ideal for F4 CEZ teams racing at the same venue two weeks later.

• Formula 4 / F4 CEZ
• Formula D2
• Formula Renault
• Formula 3
• & more

What you need to know

The mandatory briefing for all drivers takes place on 27 August at 08:30. If you want to arrive early: pit setup is already possible on Wednesday, 26 August from 19:00 — for everyone who would rather head straight into the cockpit on Thursday than start by setting up camp.

• Mandatory briefing: 27 August, 08:30
• Arrival & pit setup: possible from Wednesday, 26 August, 19:00
• Fuel station in the paddock: 98 and 100 octane, card payment

• Event photography: included
• Format: Open Pitlane, max. 28 cars per group

The track

The Automotodrom Brno — known in German as Brünn — is one of the most storied race tracks in Central Europe. Fast, technical and yet fair enough that you immediately feel at home as a driver. Long full-throttle sections alternate with tight, rhythmic passages. The asphalt, completely renewed in 2025, makes it all the more interesting. If you're not smiling here, your helmet strap is too tight.

And: two weeks before the race weekend of the Masaryk Racing Days — with the F4 CEZ as one of the highlights of the support programme — our test day at the Masaryk Circuit is the best opportunity to understand the track before things get serious.

What sets TWENTYSEVEN apart

We deliberately limit the number of participants. Not because we have to, but because we want you to test — not wait. Our aim is to create the setting in which you and your team get the most out of every kilometre.

Brno is no unfamiliar territory for us. We know the track, we know how it operates, we know the requirements. Everything else — engine noise, the smell of tyres, the stopwatch — you bring along.

27 August. Masaryk Circuit. Secure your spot.

Both groups are strictly limited. Those who come too late will be testing elsewhere.
