The T1 platform is brand new and engineered from the ground up to underpin full-size pickup trucks and SUVs.
It has been rumored that GM intended to utilize the T1 platform to underpin both its midsize and full-size body-on-frame pickup trucks and SUVs. However, the effort to underpin the mid-size models was scrapped. As such, the platform is now believed to be capable of supporting full-size body-on-frame models.
T1 support a wide range of GM’s four-, six-, and eight-cylinder GM engines and transmissions.
Applications of the T1 platform include:
- Fourth-generation 2019 Chevrolet Silverado and newer
- Fifth-gen 2021 Chevrolet Tahoe and newer
- Twelfth-gen 2021 Chevrolet Suburban and newer
- Fifth-gen 2021 Cadillac Escalade / 2021 Cadillac Escalade ESV and newer
GM is believed to be working on a version of the T1 platform capable of supporting Battery Electric Vehicles (BEVs). That version of the architecture is referred to internally as BT1, short for Battery T1.
