This involved climbing an insane 999 steps, with around 99 turns to get to the top, becoming the first production auto to do so.
Land Rover needed a good driver for the challenge, so it chose Le Mans class-winner and Formula E Panasonic Jaguar Racing reserve and test driver Ho-Pin Tung.
Land Rover has taken the new Range Rover Sport Plug-in Hybrid (PHEV) for a run up China's Dragon Road, and scaling the heights of Heaven's Gate - the first time for an SUV.
The Range Rover Sport PHEV, for which United Kingdom order books are now open, is powered by a hybrid drivetrain consisting of a four-cylinder petrol engine and an 85kW electric motor.
Land Rover loves to take its SUVs to places few other vehicles have ever gone before, and the latest episode of that saga involves a Range Rover Sport PHEV and the staircase leading to China's Heaven's Gate on Tianmen Mountain.
The new PHEV powertrain gives the Range Rover Sport a zero-emission EV range of up to 50km when fully charged but Ho-Pin Tung used its advanced 300PS Ingenium petrol engine and 116PS electric motor to make short work of the road section of the challenge. The performance SUV then showed its uncompromised all-terrain credentials by climbing the steep staircase to the natural rock arch.
Phil Jones, Land Rover Experience expert, said: 'This was the hardest Range Rover Sport challenge I've ever been involved with because, until we reached the top, we couldn't categorically say we would succeed. But just because it's a plug-in hybrid doesn't mean it's not a true Land Rover with serious capabilities.
Previous exploits include a record-setting hill-climb at Pikes Peak, a record crossing of the "Empty Quarter" desert in the Arabian Peninsula and a 2,170m descent of the legendary Inferno downhill course in Mürren, Switzerland.
