The Audi A4 is a compact car with a hint of luxury. The A4 was also produced in a convertible body and eventually replaced the old Audi 80 convertible, which was discontinued in 2000. The new A4 is built on the Volkswagen B6 (PL46) platform, and its design is clearly influenced by the existing Audi A6. The car has an electro-hydraulic roof system that can lower the roof in 30 seconds. The convertible differs from the regular version in body color with painted bumpers, a silver front strut, and a slightly different instrument panel. An all-wheel drive system with a 50:50 power distribution between the front and rear axles has also been produced again, but there is also the option of a 25:75 or 75:25 distribution. The Audi Tiptronic gearbox has been replaced by the new Multitronic, which is considered one of the best of its kind in the world. Drivers especially appreciate the quattro system, car comfort, beautiful design, quality interior, good handling. Among the disadvantages is the cramped rear seat.
