The first generation IS came to Lexus by way of Toyota. While the RWD entry-level Lexus was quite competent, it was never quite as solid as its siblings. The new IS a purpose-built Lexus with the refinement, gadgetry and flawless execution to match. On paper, the new IS poses a credible threat to the standard-bearing 3-series. Two V6 models are offered: the 200hp IS250 and the 300hp IS350. The IS250 is offered in both RWD and AWD. All models feature six-speed transmissions, but only the RWD IS250 offers a stick.

The most notable new feature is a standard VDIM/VSC cut-off function.
