The A4 sedan remains embroiled in a longstanding rivalry with the Mercedes-Benz C-Class and BMW 3-Series.
The C-Class gets some extensive changes for 2012, including a new base turbocharged four-cylinder engine, in the C250, so it's now pretty much up to snuff with the A4's more fuel-efficient sensibilities.
The BMW 3-Series is still the most popular with the traditional crowd of driving enthusiasts, though the latest 3-Series has become heavier and quite a bit more expensive; its turbocharged inline-six offers brilliant power, however.
The Infiniti G37 is an interesting alternative, sporting BMW-like handling and matching it with Japanese design flair; but the G can feel a bit coarser with respect to road noise and powertrain refinement.
The Cadillac CTS is perhaps GM's best effort yet, with remarkable handling and top-notch entertainment and trims.
And the Acura TL is worth considering, too, for its somewhat roomier backseat, composed ride, and surprisingly good handling, especially in all-wheel-drive versions.
