Land Rover has confirmed that it will launch a convertible version of the Range Rover Evoque in 2016, and did so by releasing a film shot in the Crossrail tunnels.

The film shows a disguised prototype of the Evoque Convertible being lowered 40 metres beneath the streets of London, before driving through the network of 6.2-metre wide tunnels.

Crossrail is a series of tunnels, 26 miles in length, that will connect the City of London, Canary Wharf, the West End and Heathrow Airport to the capital’s prime commuter areas.

The project began in 2009 and has so far seen 4.5 million tonnes of material excavated from underneath the busy city, making it the biggest and most expensive construction project currently under way in Europe.

Land Rover has released only minimal details about the new Evoque Convertible, although it did say it would be built at the company’s Halewood plant in the UK, alongside the existing Range Rover Evoque models.

More details will be released later in the year, with the Evoque Convertible expected to go on sale in the UK in 2016.
