When Renault’s training shoe-loving design boss Laurens van den Acker joined the company in 2009, he set to work on implementing a new design philosophy based around the petals of a flower.

Although it might sound pretentious to some, it was actually remarkably easy to understand, and as van den Acker industriously reinvented Renault’s entire model range, the strategy paid off, providing the French manufacturer with a line-up of vibrant and desirable designs.

Now van den Acker and his team are starting that design process again, kicking things off with the stunning Renault Trezor coupé that has been unveiled at the Paris motor show, just as 2010’s DeZir concept signalled the start of the first design cycle.

While the Trezor is a no-limits concept that won’t be turned into a production car (although some elements of its interior and technological capabilities will feature in future Renaults), van den Acker has promised that the next car in the design process will be “a more responsible” creation more closely previewing a production model.

During a design evening ahead of the Paris motor show, Anthony Lo, Renault’s exterior design boss, shed light on how van den Acker’s impact has helped to change the mentality within the company.
