The Audi RS 5 features a high-revving 4.2-liter V8 with 450 horsepower and a seven-speed S tronic® transmission with launch control program. The 4.2 liter, naturally aspirated FSI® engine delivers 450 horsepower and 317 lb-ft of torque to propel the RS 5 from 0 to 60 in just 4.5 seconds and an electronically-governed top speed of 174 mph. The vehicle's dynamically elegant styling extends to the interior, where power-adjustable sport seats with pronounced side bolsters and integrated head restraints are finished in fine Nappa leather or optional leather / Alcantara®. Rock gray seat piping adds to the sporty look of the interior. An RS flat-bottom steering wheel is covered with perforated leather. The instruments have black gauges and white lettering with distinctive scaling. The driver information system integrates a lap timer for recording circuit times and an oil-temperature gauge. The interior is black, and the decorative dash inlays are made of carbon fiber. The pedals and the footrest, trimmed in aluminum, add to the performance elements of the RS 5. Aluminum inserts adorn the door sill trims, and RS 5 logos lend dynamic highlights to the interior in the instrument cluster, gear shifter, seats and on the Audi MMI® Navigation plus welcome screen.
