GX generations, and what changed
These boundaries are not copied from a brochure — they fall out of the measurements. Where the GX's length or wheelbase jumps between consecutive model years the platform changed: a facelift moves a bumper by centimetres, a new generation moves the whole car — for the GX that gives 4 distinct generations below.
| Generation | Length | Wheelbase | Weight | vs previous | Weight change |
|---|---|---|---|---|---|
| 2005-2008 | 480 cm | 280 cm | 2150 kg | - | - |
| 2011 | 481 cm | 279 cm | 2408 kg | +1 cm | +258 kg |
| 2014-2023 | 488 cm | 279 cm | 2350 kg | +7 cm | -58 kg |
| 2026 | 500 cm | 285 cm | 2570 kg | +12 cm | +220 kg |
Between 2005 and 2026 the GX gained 20 cm in length (+4.2%) and 420 kg in weight (+19.5%). Cars did not so much grow as thicken — crash structures, airbags and equipment weigh more than the metal they replaced, and on the GX that is 420 kg against 20 cm. Full dimensions by year →

Can a Lexus GX tow? Towing & payload
As an SUV, the Lexus GX is built to tow and haul. The exact maximum towing capacity and payload depend on the engine, drivetrain and whether it has the factory tow package.
What sets your GX's tow & payload rating:
- Engine — a larger or turbocharged engine tows more than the base unit.
- Drivetrain & axle — 4WD/AWD and the axle ratio shift the rating.
- Tow package — the factory towing package (hitch, wiring, transmission cooler) raises the max.
- Payload & GVWR — GVWR caps the combined load; more passengers and cargo lower how much you can tow.
Exact towing capacity, payload and GVWR are added per engine, drivetrain and trim — decode your VIN above, or check the driver's door-jamb and hitch labels. Curb weight from vehicle specifications.
