The current "entry level" model for the Lexus sedan line, the IS consists of the IS 250 in rear-drive or all-wheel-drive variations and the more potent rear-drive IS 350 – as well as the high-performance version, the IS-F (reviewed separately). Visually reminiscent of the larger GS, the IS melds sporty looks, enthusiast flair, a generous roster of standard equipment and legendary Lexus quality into a premium four-door sedan specifically intended to steal buyers away from the gold standard of this segment, the BMW 3 Series. Other competitors include Acura TSX and Audi A4, both of which are marginally more spacious inside.
