2017 Audi A5/S5 Review – Video
While the German press materials mention both gas and diesel engines, we expect the A5 to carry on in the US with petrol power only. Like the current A5, a 2.0-liter, turbocharged four-cylinder will serve as the base engine, but will probably get a similar power bump as the A4 – Audi hasn’t released official figures yet. The four-door had its base output bumped from 220 horsepower and 258 pound-feet of torque to 252 hp and 273 lb-ft of torque.
The original S5 featured a 4.2-liter, naturally aspirated V8. A few years back, that was replaced by a supercharged 3.0-liter V6, which in turn has been supplanted in the 2017 S5 by a turbocharged 3.0-liter V6. The turbo, a twin-scroll unit nestled between the cylinder banks, helps the direct-injection engine make a healthy 354 horsepower and 369 pound-feet of torque. That power, 21 hp and 44 lb-ft more than its predecessor, is channelled through Quattro all-wheel drive.
