Land Rover has just completed a wildly ambitious, 10,472-mile journey from its Solihull, UK factory to the home of its parent company, Tata, in Mumbai, India with a trio Range Rover Diesel Hybrid prototypes. The epic journey, known as Silk Trail 2013, took a total of 53 days, and saw the team cross 13 countries along the way.

For a large portion of the journey, the team traveled along the historic Silk Road, a series of trading routes pioneered first by the Chinese, but known mainly to the western world thanks to the travels of Venetian trader Marco Polo. Somehow, we imagine the journey in the Range Rovers was faster and more comfortable than either the Chinese or Polo could have ever imagined.

But simply because the Silk Trail team was hurtling through the countryside in a very comfortable off-roader doesn't mean it was an easy trek. Between the three Range Rovers, there were 15 flat tires along the way, and the drivers and support staff spent a full week at altitudes of over 11,000 feet, going as far up as 17,648 feet.

Through it all, the team collected over 300 gigabytes of tech info on the performance of the three prototypes, and returned a reported 36 to 37 miles per gallon between the three Range Rovers (measured on the UK cycle, we imagine).

Jaguar Land Rover Director of Hybrids and Electrification, Peter Richings, said of the trek, "In developing the hybrid-powered Range Rover, our objective was to gain hybrid's fuel economy and carbon emissions advantages without compromising the Range Rover's go-anywhere capabilities, its cabin space or its refinement. The success of this remarkable expedition clearly demonstrates we have achieved that."

LAND ROVER COMPLETES WORLD'S FIRST HYBRID EXPEDITION ALONG SILK TRAIL FROM SOLIHULL TO MUMBAI

Three Range Rover Diesel Hybrid prototypes complete 10,472 miles along the Silk Trail from Solihull, home of Land Rover, to Mumbai, home of Jaguar Land Rover's owners, TATA
Journey covered 53 days, 13 countries and two continents putting the Range Rover Hybrid prototypes through their final extreme engineering sign-off test
Tested to the limits in temperatures from -10 degrees to 43 degrees Celsius at altitudes of 5500 metres and over every type of terrain
First foreign-registered cars to drive China's Xinjiang-Tibet highway


Land Rover's first ever production hybrid to go on sale in first quarter 2014 (selected markets only)
Mumbai, 14 October 2013. Three Range Rover Diesel Hybrid prototypes have completed the ultimate engineering sign-off test by traversing 13 countries over 53 days from Solihull, UK, to Mumbai, India. It is the world's first ever hybrid expedition along the Silk Trail and one of the boldest driving adventures ever pursued by Land Rover.

Hostile conditions on the route included asphalt roads riddled with vast and deep potholes, dusty desert trails in 43°C heat and numerous miles of mud and gravel tracks and cattle trails. In addition, river crossings, passes clinging to the edges of mountains partly blocked by rock falls, the thin air of extremely high altitudes and the dense and erratic traffic of Chinese and Indian roads all added to the test of man and machine.

The Silk Trail 2013 expedition was the final validation test for the Range Rover Hybrid before it is signed-off for production. From the home of the Legend in Solihull, UK, it blazed a trail through France, Belgium, Germany, Poland, Ukraine, Russia, Kazakhstan, Uzbekistan, Kyrgyzstan, China (including Tibet), Nepal and India. For much of this distance the expedition followed the legendary Silk Road trading routes that first connected Asia with Europe more than 2,500 years ago. Overnight halts were made in hotels, hostels and tents at many of the same staging posts visited all those years ago by Silk Road merchants, missionaries and mercenaries.

Where the north and south Silk Roads split, near the remote city of Kashgar in north-western China, the expedition pioneered a mountainous route never previously completed by a vehicle from outside the country and never previously seen in its entirety by any westerner – the Xinjiang-Tibet highway, which put the new Range Rover Hybrid through its paces at heights of over 5,300 metres above sea level.

Seven consecutive days were spent at altitudes between 11,000 and 17,648 feet (3,350 and 5,379 metres). At such great heights, oxygen content in the air is reduced from the 21 percent found at sea-level to as little as 10 percent, making movement more difficult for humans and internal combustion engines. The Range Rover convoy continued to make good progress, benefitting from the electric motor's instant torque at 0 rpm and despite being laden with heavy loads including luggage, camping gear, food, medical equipment, and aerodynamically-unfriendly roof-racks carrying spare wheels, tyres and jerry cans of fuel.

Negotiating tracks so sticky with mud that they were impassable to other types of vehicle, the Range Rover's hybrid engine combination – with a 35kW electric motor supporting the TDV6 3.0 litre turbo-diesel engine – returned excellent fuel consumption for a vehicle so spacious and powerful. Throughout the epic journey the Range Rover Hybrids typically returned 36 to 37 mpg.

Land Rover development engineers closely monitored data loggers fitted to each car, sending back more than 300 gigabytes of detailed technical records to their engineering team at Gaydon in the UK. The purpose of the expedition was not to test the reliability of mechanical components, which are already proven, but to fine-tune the calibration of engine and transmission software to ensure perfectly seamless performance in all terrains and extreme temperatures and altitudes. Technical setbacks reflected the roughness of the road surfaces: 15 punctures among the expedition's three Range Rover Hybrids and four support vehicles, four wheels damaged by deep potholes, and four windscreens cracked by stones thrown-up on loose surfaces.

Peter Richings, Jaguar Land Rover Hybrids and Electrification Director who took part in the final leg from Jaipur to Mumbai commented: "The world's first diesel hybrid expedition along the Silk Trail pioneered an ambitious route across Europe and Asia that would have been impassable to most other types of vehicle – but no matter how hostile the conditions, the Range Rover Hybrid prototypes took it all in their stride.

"In developing the hybrid-powered Range Rover, our objective was to gain hybrid's fuel economy and carbon emissions advantages without compromising the Range Rover's go-anywhere capabilities, its cabin space or its refinement. The success of this remarkable expedition clearly demonstrates we have achieved that."

      You mention a "UK cycle" when talking about fuel mileage in this story. You do know that an Imperial gallon is larger than a US gallon, right? This makes the numbers higher even if using the same test methods.

      Silk Road? I thought that place just got shut down by the Feds.

      I thought Land Rovers were to run people over.

      Why is it when I heard "Land Rover" and "Silk Road" together, I thought "another DeLorean-style drug bust"?

      Why not go turbo-diesel? It will be more practical.

      I couldn't believe they were making a Land Rover Hybrid. I'm still not quite sold on them.

      Honest Question: Why was an LR4 brought on the trip? You can see the interior in one shot and a small part of the exterior in the other. It is, obviously, played down as a participant, but why was it brought? I owned a RR and traded down to the LR4 and have enjoyed it much more. I'm curious why it was brought along, but not showcased.

      If India was "jewel in the crown" of the British Empire I think it's safe to say Land Rover/Jaguar is the jewel for the Indian automotive empire.
