The 2013 Audi A4 gets a new hood and headlights, and inside, there's a new instrument cluster with simplified layout for the Multi Media Interface (MMI) electronics control. Electric power steering replaces the previous hydraulic boost. The A4 Avant wagon goes away with the arrival of the new Allroad.
Once offered in multiple body styles, the 2010 Audi S4 is available to U.S. consumers in sedan guise only. Mechanical upgrades include a new supercharged 3.0-liter V6 engine, an available seven-speed dual-clutch automatic transmission and a Sport Rear Differential system tied to standard quattro all-wheel drive.
Where other premium brands have the prerequisite parts to comprise a midsize luxury car, Audi's A4 and S4 for 2015 combine wood, leather, chrome and steel in a way that transcends mere transportation. The A4 sedan's powerful yet fuel-efficient turbocharged engine is an Audi hallmark, while the high-performance S4 meshes a supercharged V6 with the company's advanced quattro all-wheel drive (AWD) to create a sports sedan experience like no other. With other luxury sedans such as the BMW 3 Series, Cadillac CTS and Infiniti Q50 all vying for the same audience, Audi's A4 and S4 performance sedan duo face tough competition. Luckily for Audi, there is no substitute for what the quadruple ring emblem represents to some buyers.
