Audi just dropped details on the revamped A5 and S5 cabriolets, rounding out the next-generation A5 lineup. The mid-size two-doors offer room for four passengers, plus a revamped exterior, larger cabin space, new technology, and refreshed powerplants.

Outside, it’s more or less the same recognizable Audi exterior design. For 2017, the Four Rings added a flatter rear window and a wider and flatter Singleframe grille. The exterior dimensions have increased, as the A5 is now extended by nearly two inches. Optional LED or Matrix LED headlights are up front, while LED taillights are in back.

The larger cabin now gets standard microphones mounted in the seatbelts, plus an 8.3-inch display and lots of driver assistance features. The one-touch automatic soft top can flip up or down at speeds up to 31 mph, with just 15 seconds required to open and 18 seconds required to close.

The 2017 model year brings three engines for the A5, including a 2.0-liter gas unit with 252 horsepower, a 2.0-liter diesel with 190 horsepower, and a 3.0-liter diesel with 218 horsepower. A 2.0-liter gas unit with 190 horsepower and a 3.0-liter diesel with 286 horsepower are expected to follow the initial market launch. Transmission options include a six-speed manual, seven-speed S tronic, and eight-speed tiptronic.

More speed can be had with the new S5, which makes 354 horsepower and 369 pound-feet of torque thanks to a turbo 3.0-liter V-6. Routed to the ground via standard quattro AWD, it’s enough to hit 62 mph in 5.1 seconds, while top speed is electronically limited at 155 mph.

The suspension is now a new five-link for the rear, supplanting the old trapezoidal-link set-up. Corner carvers can get the available adaptive dampers or available dynamic steering.

Look for the 2017 Audi A5 and S5 to make their public debut at the Los Angeles Auto Show later this month.
