GM first provided details on its Global B electronic architecture back in May. The new digital “nervous system”, as the automaker calls it, has much greater data processing power than GM’s outgoing electronic system and stronger connectivity.
The system will be commonplace going forward, as it will be necessary to support over-the-air updates, semi- and fully-autonomous driving functions and new advanced infotainment technologies. All future battery electric vehicles from GM will also be based around Global B.
“As the automotive industry and vehicles evolve in the next five to 10 years, more electrical bandwidth and connectivity will be needed to ensure that features like electric propulsion systems, the Super Cruise driver assistance feature and advanced active safety systems can all run in conjunction with each other,” Cadillac stated in a recent press release announcing the arrival of Global B.
The Cadillac CT4 is based around GM’s Alpha platform, which previously served in the Cadillac ATS and CTS, however it is still a much different vehicle thanks to its different smaller footprint, different exterior styling and more up-to-date powertrain offerings. Cadillac Society notes that now, with confirmation that the CT4 will also utilizes the Global B electric architecture, the CT4’s position as an all-new vehicle as opposed to a “re-skinned” ATS has been solidified even further.
The Cadillac CT4 follows in the footsteps of its larger sibling, the Cadillac CT5, in using Global B and is now the second Cadillac model to tap the new system. The 2020 Chevrolet Corvette C8 will also use the Global B architecture, as we reported previously, which is also why early, pre-production prototypes for the vehicle initially used a Cadillac key fob.
The 2020 Cadillac CT4 will go on sale later this year.
