The B9 S5, launched in 2017, uses the 3.0 TFSI twin-turbo V6 producing 354bhp. This delivers more power than the supercharged B8, with broader torque delivery and improved efficiency. It is the most complete S5 yet as an everyday performance car.
The Car
The EA839 3.0 TFSI produces 354bhp and 500Nm through an eight-speed torque converter automatic and quattro. Available as Coupé, Sportback, and, in limited markets, Cabriolet. The S5 TDI was added to the range: a 3.0 TDI producing 347bhp, mirroring the approach taken with the S4 B9 TDI. 0–62mph in 4.7 seconds in Sportback form.
Buying
The Sportback is the most popular and practical. The S5 TDI offers the same compelling efficiency argument as the S4 TDI; real-world 35mpg+ with near-supercar straight-line pace. The Audi 3.0 TFSI is a well-proven unit shared with Porsche applications. Strong used values relative to the standard A5.
