When people think of heroes, names that come to mind are John Wayne, Superman or perhaps Gandhi. When Audi executives think of their heroes, the A4 certainly makes the short list.

The Audi A4 holds the distinction of single-handedly reviving the flatlining Audi after the brand's big sales slump some two decades ago. Launched in the mid '90s, the A4 quickly proved a favorite among luxury-car buyers thanks to a handsome, well-finished cabin and available Quattro all-wheel drive. Tight panel gaps, high-quality materials and firm, comfortable seating give the interior the proper European ambiance, while a supple ride, responsive handling and willing performance make the Audi A4 a great road trip choice.

Although those core characteristics have been part of the A4's personality since day one, this compact sport sedan has become increasingly polished with each successive generation. Three generations of the Audi A4 have been produced to date and have been typically available in convertible, sedan and wagon body styles. No matter what year of A4 you look at, know that this vehicle will provide athletic performance and a comfortable and inviting cabin. Add in the appeal of all-wheel drive (a serious asset for those who live in inclement parts of the country) and it's easy to see why the A4 is such a credible hero.
