The 2018 Audi RS5 is all new. Starting with its massive air intakes, it’s clear the RS5 is no average beast. The meanest version of Audi’s sports coupe now has a 444-hp twin-turbocharged 2.9-liter V-6 instead of a naturally aspirated V-8. That’s six less horsepower than the outgoing V-8, but torque has increased dramatically to 443 lb-ft. The output routes through Audi’s rear-biased Quattro all-wheel-drive system via an eight-speed automatic. Find out if this a the highest performing RS5 ever!
