Looking to bring more excitement to its lineup, Lexus is reportedly planning a new coupe.

Lexus plans to expand its lineup with a new coupe model based off the sleek LF-CC concept that debuted at the Paris Motor Show, a new report indicates.

The two-door is intended to plug the gap in Lexus' lineup left by the discontinued SC 430, but will feature a sportier focus that's consistent with the Lexus' recent efforts to reposition itself as a more driver-oriented brand, according to an Autocar report.

A variation of the rear-wheel-drive platform shared by the GS and next-generation IS models is likely to underpin the coupe, complete with the shorter wheelbase of the IS and the wider track of the GS. A convertible model is also said to be in the works.

Likely candidates to fill the engine bay include the GS 450's hybrid powertrain and the 3.5-liter V6 used by the GS 350, although previous rumors have also suggested that a more potent mill could end up on the options list.

Development work on the production-spec LF-CC will reportedly begin in early 2013, and the coupe could hit the market as soon as 2015.
