BMW’s GT3 contender is set for a mid-cycle refresh in a little over 12 months, with the German manufacturer employing its former DTM team RMG to assist with developing its Evo package.
Although a relatively new model that was officially introduced only at the beginning of 2022, BMW has already been working on updating the M4 GT3 to keep up to pace with the competition and future-proof the car for changes in the GT3 landscape.
Testing of the BMW GT3 Evo is already underway, with the updated car first seen in action at the Spa-Francorchamps circuit in August with factory drivers Augusto Farfus, Jens Klingmann and Bruno Spengler sharing the wheel.
But the purpose of the Evo package goes beyond performance upgrades, with BMW motorsport boss Andreas Roos explaining it is working on making improvements to the overall package.
"It's still in development at the moment, we're still testing,” Roos told Autosport’s sister title Motorsport-Total.com.
“You have to differentiate between pure development and durability testing, which means doing endurance runs.
“Because the M4 GT3 also does a lot of endurance racing, durability must be a given, but of course there are also the issues: do all the parts work, performance developments, etc?
“We were mainly concerned with improving this car, which we have now seen. It's not just about making the car faster, because at the end of the day it's a BoP championship. So it's always relative.
