Last updated August 4, 2026

About the 2020 Jeep Gladiator
JT generation, first model year
Jeep positioned the Gladiator as an outdoor-adventure midsize pickup that blends Wrangler-style off-road ability with useful truck hardware. Its identity centers on standard 4WD, low-range gearing, a five-passenger cabin, a 5-foot cargo bed, and stronger towing and payload capability than a Wrangler. The key difference from conventional midsize pickups is its combination of serious trail hardware, distinctive Jeep design, and an open-air body structure.
The range stretched from the straightforward Sport and more convenient Sport S to the comfort-focused Overland, which had a 7-inch touchscreen, Apple CarPlay, Android Auto, and dual-zone climate control. Rubicon focused on slow-speed rock crawling with front and rear locking differentials, while Mojave used specialized shocks, a reinforced frame, and a locking rear differential for faster travel over rough terrain. The limited Launch Edition paired Rubicon hardware with navigation, upgraded audio, LED lighting, and added driver-assistance features.

2020 Jeep Gladiator Reviews
What owners are saying about the 2020 Jeep Gladiator.
4.5
2020 Jeep Gladiator
(373 reviews)
“Love: Wrangler features like taking the doors and top off. Truck bed capacity. 8 speed auto transmission is smooth. Modern tech like big screen on dash, LED lights, backup cam. Hate: everything is digital and the dash layout is not intuitive.”
“It's a 3 in 1 vehicle that is practical and fits my needs and expectations, not too big, not too small, just right.”
