The Audi A4 faces stiff competition from the likes of the BMW 3-Series, the former benchmark for sport sedans, and the Mercedes-Benz C-Class, which introduces a new level of luxury to this segment.
A recent redesign of the Lexus IS has made these cars more competitive, and the new Cadillac ATS has surpassed the BMW for dynamic capability.
We're also intrigued how the new Audi will stack up against the Infiniti Q50, a sedan we like immensely when it's not fitted with the brand's squirrely steer-by-wire system.
