The GB3 Championship will have a new feel about it in 2025, with a brand-new car, a revised calendar, and plenty of other changes to look forward to.

The Tatuus MSV GB3-025 makes its race debut

Having completed a comprehensive development testing programme across circuits in Italy and Spain in the two months before Christmas, the
Tatuus MSV GB3-025 has already proven to be quicker than its predecessor and will be a hugely exciting addition to the GB3 Championship.

The F1-inspired new machine is built to meet latest FIA safety regulations but benefits from a big increase in downforce and an extra 30 horsepower.
In addition, the inclusion of DRS for the first time will add an extra spice to the racing, while wider Pirelli tyres add further grip for the drivers.

DRS adds to new car challenge

GB3 adds the Drag Reduction System to its new car for 2025, with attacking drivers now able to use the device to increase their overtaking chances.

Like in Formula One, drivers will have free use of the DRS in qualifying, when travelling through permitted DRS zones around the circuit. In races, drivers
must be within a second of the driver in front when passing through a detection point, to be able to open the rear wing through the DRS zone which follows.

The DRS will not be usable during the first lap of each race, immediately after a safety car period, or if Race Control deems conditions are not suitable
for its use (for example, in poor weather or visibility).

Monza joins the calendar

GB3’s continental appeal grows further in 2025, with the inclusion of Monza for the first time. Of GB3’s eight race weekends, six will be held on contemporary
F1 layouts, with Zandvoort, Spa-Francorchamps, Hungaroring, and the customary double Silverstone visit remaining a key part of the calendar. Monza has the
honour of hosing the GB3 season finale in 2025.

Revised race weekend format

Qualifying is now set to be a two-part session, with each segment forming individual grids. The first 15 minutes will determine the starting order for race one,
and the second, also of 15 minutes duration, will form the race two grid, while the race three grid format remains unchanged, again featuring a top 12 reversal
of the fastest qualifying times.

The race length has also been extended, with all three contest now 25 minutes long.
