Lexus has revealed a convertible version of its LF-A super car concept at the 2008 Detroit Motor Show - dubbed the LF-A Roadster. The LF-A Roadster is based on the sturdy yet lightweight carbon-fibre and aluminum body used for the LF-A coupe, which helps maintain the structure's strength and rigidity even without a top. Like its coupe counterpart, the LF-A Roadster is powered by a high-revving V10 engine that approaches 5.0 litres in displacement. Styling of the LF-A Roadster draws from the Lexus L-Finesse design philosophy, with a compact, low-profile, aerodynamic front end.
