rFactor 2 GT3 BOP Release

GT3 BOP Updates

Endurance and GT racing has been brought up on the ethos of converging differing Grand Touring Car designs and shapes into an even playing field of competition. Nowhere else in the world of motorsport can you find such an eclectic mix of different cars, brands and design concepts coming together and competing on the same track, with similar chances of challenging at the very front of the grid.

As GT3 specification competition has continued to grow in popularity around the world, much of the success of the category has to be laid firmly at the door of the less than glamorous world of Balance of Performance, or BOP as it is more commonly known.

Always the subject of many off track debates amongst teams and drivers, BOP is a method employed by many championships to ensure cars of differing shapes and sizes can race together fairly within a common set of regulations, preventing the potential for runaway championship leaders and ensuring a fair shot of success is open to all brands within a series.

As in the real world, our virtual counterparts in rFactor 2 are also subject to these BOP restrictions, as unlike the real world counterpart, should a car prove to be consistently superior to its class rivals, it is rather easier for the sim racer looking to gain an advantage and select the fastest car than it is for a real world team to find hundreds of thousands of dollars to swap machines for the season ahead.

As such, here at Studio 397 we have been working incredibly hard to bring a realistic and fair Balance of Performance to the enviable list of GT3 cars currently in the simulation. Our development team and testers have pounded round the circuit for endless hours tweaking and refining the cars to ensure they retain their individual characters, their inherent strengths and weaknesses and their real world performance levels, whilst still providing an even set of ultimate speed in comparison to each other – just like in the real world!
