The first F-inagled Lexus to make its debut will be a hotted-up version of the IS sedan, equipped with a 5-liter V8. What was originally assumed to be called the IS500, the newly dubbed IS-F will come with a revised version of the V8 that resides in the LS600h L and will produce upwards of 425 HP. Pricing is expected to come in around $50k, and is aimed squarely at the upcoming M3.
