Underneath this test mule purporting to be a convertible Lexus IS-F is actually the next-generation version of the firm’s new IS, due on sale next year.
Lexus has confirmed that an IS-F cabrio is not in the current product plan, and the car was acting as a test mule for another model.
US media who saw the mule up close at its test session at the Nürburgring last week report that there were a number of clues that gave away its identity. Chief among these were the aluminium lower control arms of the test car’s rear suspension. The current IS and IS-F use steel. The new GS, on which the next-gen IS will be substantially based, uses aluminium for the multi-link rear suspension and has the option of rear-wheel steer.
