Iconic auto brand Mini has announced the addition of a sixth model to its lineup, the Mini Roadster that will launch alongside the MINI Coupe hardtop in March.

The first open-topped two seater in Mini history, the Roadster is set to go on sale next spring to compete with the likes of the Mazda MX-5.

With a manually-opening soft-top roof, the model is designed to be more free-spirited than the four-seater Mini Convertible, with a sweeped look, lower profile and a steeped rear end, which holds a manually-operated roof.

MINI has revealed the first two-seater in its model range, promising the “ultimate in go-kart feeling.”

The MINI Coupé is the latest variant in the rapidly-expanding Mini range and daringly introduces some premium racing features into the brand’s familiar shell.

Most noticeable among these is the flattened roof form, which MINI says has improved the aerodynamics of the vehicle, and an active rear spoiler which extends automatically at speeds of over 80km/h.

Mini has celebrated its 50th anniversary at the Frankfurt Motor Show with the Coupe Concept and Roadster Concept.

BMW has already confirmed these two concepts are headed for production, expanding the Mini line-up to no less than six models.

The original hatch has been joined by a convertible and the Clubman extended wagon, and there’s a crossover utility version on its way.
