Renault says the Nepta's design is inspired by classic grand tourers, although the details and technology are thoroughly modern. The proportions and stance are very stately, with a long, tapered rear end containing a sizeable overhang. The Nepta features wave-shaped panels to create a sense of fluidity, while the car has a two-tone effect thanks to the aluminium lower body section.
The wheels measure 23 inches in diameter, and their massive size is in keeping with the Nepta's barge-like dimensions. It measures almost 5m-long, and is wider (though lower) than Bentley's forthcoming GTC cabrio.
