With sales expected to top more than a million units worldwide within the next two to three years, Lexus is planning a host of new models to help keep the momentum going. First up is the replacement for the RX crossover, due early next year, but after this comes a host of new ‘F’ performance models including a production version of the LF-A supercar concept as well as a new entry-level model.

Lexus will expand its F range to include a performance version of the GS sedan and possibly the full-size LS limo, with the hope to establish the brand as a true rival to BMW’s M division and Mercedes AMG. The information comes from Lexus’ Australian chief John Roca, who spoke recently with The Australian.

In addition to the performance range, Roca confirmed Lexus will add a model below the IS to rival the BMW 1-series and Audi A3 models but stated that it was still a few years away. In the meantime, Roca explained that Lexus will concentrate on its hybrid technology and is planning to add a hybrid option on every model as well as debut a new dedicated hybrid concept at next year's Detroit Auto Show.

Next year will see the launch of the next-generation RX crossover, based on the LF-Xh concept (pictured) from last year’s Tokyo Motor Show, as well as a new coupe-cabrio version of the IS complete with a folding metal hardtop.

When asked about the LF-A supercar, Roca confirmed the car is destined for production and hinted at a 2011 launch date.
