The Trailboss trim integrates the off-road equipment of the Z71 package as well as a 2-inch suspension lift. Unlike aftermarket lift kits, the Trailboss suspension is fully tested, validated and warrantied by Chevrolet.
As for powertrains, GM currently offers three engine options — a 4.3-liter V-6, 5.3-liter V-8 and 6.2-liter V-8 — compared with Ford's five offerings, including three turbocharged engines. GM is expected to increase its engine offerings, however, it has not released details.
"GM is going all-in, putting all their chips in, on engine technology," Sullivan said.
The next-generation pickups are expected to use braking-by-wire to reduce mechanical parts and have a new 10-speed automatic transmission that GM co-developed with Ford, which already is using the technology on the F-150.
The pickups also will feature new axles. In January, GM announced it was bringing axle production in-house for its next-generation full-size pickups — likely signaling significant advancements in those parts.
