What Changed

GM's full-sized trucks are all-new for 2014. Although the trucks have been restyled they are in large part the same size as their predecessors. Extended cab models now feature four front-hinged doors and crew cab models have a much larger interior. Powertrain choices include a 4.3l V6, 5.3l V8, and a 6.2l V8. Trim levels are largely unchanged, with base, SLE, and SLT trim levels. The high-end Denali trim level is available on Crew Cab models only.
