The Audi A4's chief rivals are the BMW 3-Series and Mercedes-Benz C-Class.
The BMW 3-Series is perhaps the most popular, though in its current edition, it's become heavier and quite expensive, yet its turbocharged inline-six offers brilliant power.
The Mercedes C-Class has more capable handling than before, but rear-seat room is still cramped and its interior styling a little complex.
The Infiniti G37 sports BMW-like handling with a distinctly Japanese flair, while the Cadillac CTS is perhaps GM's best effort yet, with remarkable rear- or all-wheel-drive handling, ample V-6 power, and a world-class entertainment system.
