The 2015 Lexus IS runs up against a few very hearty competitors in the mid-size luxury segment, but it does so in a seriously competitive way.
The Cadillac CTS offers tons of technology, a comfortable ride, and a performance-oriented "V-Sport" model with more power than new IS currents offers.
The BMW 3-Series is softer than it has been in the past, but still drives well, and the all-new Mercedes-Benz C-Class feels a notch above the rest of the segment in terms of true luxury.
There's also the Audi A4, which feels like the most understated option in the bunch–but we enjoy its excellent interior, handsome exterior, and all-weather functionality.
