The 2018 Audi A5 and S5 Cabriolets are here just in time for winter

There are no big surprises with the 2018 A5 and S5 Cabriolet. As you'd expect, the convertibles share a design with their coupe counterparts, the A5 and S5 coupes, refreshed versions of which were unveiled earlier this year. Alongside the coupes and upcoming sportback models, the Cabriolets complete the A5 lineup. At least until another RS 5 comes along.

In Europe, the A5 will have five available engine options, including three TDI engines maxing out at a 286-horsepower 3.0-liter, and two TFSI gas engines, with the most powerful putting out 252 hp. There will also be a choice of three transmissions including a six-speed manual, a seven-speed S-Tronic dual-clutch gearbox, and as an eight-speed automatic.

For the US, though, the powertrains should be the same as the new coupe's, with a 2.0-liter turbocharged four-cylinder generating 252 hp and 273 lb-ft of torque in the A5, replacing the 220-hp turbo four in the previous model. An eight-speed automatic is a definite, although the existence of a manual A4 sedan for our market leaves some hope that a six-speed could be available in the A5 Cabriolet or at least the coupe. Audi also hasn't made final decisions on whether a front-drive model will be available here as it has been in the past.

The S5 Cabriolet, just like the two-door model, uses a new 3.0-liter turbocharged V6 engine that produces 354 hp and 369 lb-ft of torque, which is 21 more horsepower and 44 more pound-feet of torque than the old 3.0-liter supercharged V6 made. Despite the bump in power, the new S5 Cab hits 62 miles per hour in 5.1 seconds, just like the previous model. It is again electronically limited to 155 mph. And like the coupe, it will use an eight-speed automatic and get Quattro all-wheel drive standard.

The A5 Cabriolet loses roughly 88 pounds compared to the previous model. The cars use an updated five-link front suspension and Audi claims the chassis is 40 percent stiffer than before. The soft tops have more insulation to cancel out road noise, take 15 seconds to open, and 18 seconds to close. You can do either at speeds up to 31 mph.

The A5 Cabriolet will be available with Audi's latest array of driver assistance systems, including its navigation-linked adaptive cruise control and collision avoidance assist. A seven-inch display, seat belt microphones, Audi's Virtual Cockpit infotainment and gauge package, and a head-up display are available on the inside.

The new A5 and S5 Cabriolets will go on sale in Europe in the spring of 2017, with a US rollout shortly after. And while the 2016 LA Auto Show is just over a week away, Audi tells us these new convertibles won't be in display there.
