At Lexus, 'F' is their exclusive designation for high performance. Not that a fiery red advanced lightweight supercar, aggressive in stature and design, bore any clues in itself. The LF-A Roadster concept makes its European debut at Geneva this week, presenting showgoers with a re-interpretation in drop-top guise of the LF-A Coupe concept.

The F-Sports programme overhauls numerous technological components including powertrain, suspension and braking system to produce a concept car every bit as refined as it is exclusive. The result: a highly-polished driver-oriented vehicle highly capable in performance and handling precision.

Its design can be largely attributed to Lexus' L-Finesse philosophy and to the engineering requirements of a refined, lightweight performance vehicle. Based on the lightweight construction of the coupe, the roadster retains rigidity and structure strength by utilising lightweight but durable aluminium and carbon-fibre panels.

A low-profile stance and short overhangs contribute to an aggressive persona and also improve aerodynamic flows, while modified versions of the coupe concept's front and side profile air intakes, the latter based on single-seat racing cars, aid cooling. Large cooling duct grilles stylise the rear which incorporates a re-interpretation of the coupe's 'arrowhead' design.

Under the bonnet, a lightweight V10 unit, placed in what engineers call a 'front-mid' configuration, delivers 500 hp from less than 5.0-litres capacity and propels the LF-A Roadster to speeds in excess of 200 mph. Off-the-line sprints are as yet unpublished.

Maximising cabin space, functionality and further reducing weight, numerous components have been refined and condensed. Therefore inside, where exclusivity is key, a driver-focused environment reinforces space via a low-level console and support via sports seats and deep footwells. Stylish and exclusive touches include an F-Sports steering wheel, floor hinged alloy pedals and a unique instrument cluster.
