What the figures mean
The GX 550 has one powertrain, so choosing a trim does not change its horsepower or torque on lexus.com's figures. Trims differ in equipment, seating, weight and towing capacity.
The Overtrail and Overtrail+ are the off-road focused trims: lexus.com lists an electronically controlled locking rear differential for them, seating for 5 instead of the 7 listed for the other trims, and 28/26/24-degree approach, breakover and departure angles.
Lexus.com lists towing capacities of up to 9,096 lb, the highest on the Overtrail.
