A sporty variant of the A4 Cabriolet, the compact four-passenger 2009 Audi S4 Cabriolet comes equipped, with a short-throw six-speed manual transmission with a synchronized reverse gear, or a six-speed Tiptronic automatic transmission. With the quattro all-wheel drive as standard, the S4 is propelled by a 4.2L V8 engine that generates 340 hp and 302 lb-ft of torque. Other performance-oriented features include a sport-tuned suspension, 18-inch wheels with high-performance tires and powerful brakes. As can be seen in Audi S4 photos, subtle styling accents and badges distinguish the S4 exterior from the regular A4. EPA-estimated fuel economy is good for 14 mpg city/21 mpg hwy. Safety equipment for the Audi S4 features brake assist, a central locking system, an electronic stabilization program, four-wheel ABS, front and rear head restraints and a full complement of airbags.
