LAGONDA - the revived luxury car brand now owned by Aston Martin - has unveiled its possible design for an all-electric vehicle that could go on sale in 2021.

The Lagonda Vision Concept at the Geneva Motor Show is shorter and lower than traditional limousines that have to make room for a conventional engine and gearbox.

The Vision Concept would simply have to place its batteries beneath the floor - where they would provide a range between charges of up to 400 miles, or between London and Edinburgh or Los Angeles and San Francisco.

The Lagonda Vision Concept also anticipates a world with a high level of autonomy.

Its design is commensurate with level four autonomous driving, meaning the car is capable of driving itself in all routine circumstances and on all recognisable roads.

As a result, the steering wheel can not only move from left to right hand drive according to need, in autonomous mode it can also retract entirely allowing front seat passengers to rotate through 180 degrees to engage in face to face conversation with those in the back.

The interior has been influenced by leading British luxury craftsman David Linley and Savile Row tailors Henry Poole and features silk carpets and handwoven wool.
