The 2015 Audi RS3 Sportback boasts the most powerful five-cylinder engine that the German automaker has ever built. The turbocharged 2.5-liter inline engine packs 362 horsepower and 343 lb-ft of torque, delivering a 0 to 60 mph sprint time of 4.3 seconds. Power is channeled to all four wheels through a seven-speed S-tronic dual-clutch automatic transmission with torque vectoring. Additional performance details include a sport-tuned suspension, wider track and an Audi drive select adaptive dynamics system. Optional carbon ceramic brakes and an adaptive damper system are also available. Exterior styling features large air intakes and a Quattro-branded grille, with the sporty styling extending to the rear, which features a new bumper and a gloss black diffuser. A dual exhaust system and 19-inch alloy wheels complete the look. European deliveries of the RS3 Sportback begin in the summer.
