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.
