The dramatic Lexus LF-CC coupé, which made its debut at the Paris show last September, is expected to morph into a showroom model by 2015.

Autocar understands that a senior Lexus engineer has been assigned to the project and serious work will start on production engineering this month. A Lexus source said the company wanted to build a car that was “exciting and emotional” and reflected Lexus’s intended future image as ‘sporting’ brand.

The new model is likely to come in both cabrio and fixed-head forms. It is thought to be based on the same rear-drive platform as the new IS and GS models, probably using the IS’s shorter wheelbase but the GS’s wider tracks. The styling is believed to be close to the LF-CC concept car’s. The interior of the concept will be carried over and it will also be seen in the new IS.

The production version will be a hybrid, most likely using a tweaked version of the GS350h’s drivetrain, which currently offers 300bhp.

Lexus sources said the company wanted to slot the new model into the space vacated by the old SC coupé-convertible, which was discontinued in 2010. Lexus’s first SC coupé, a fixed-head model, was launched in 1991.
