Details on the next A5 have been scarce, and spy shots haven't revealed much. Our most recent images come from June of last year and show a vehicle that more or less follows the current A5's theme – a two-door A4 with a few small visual tweaks to distinguish it from the sedan, including a wider stance. Expect an interior treatment very similar to the A4's as well.
The new coupe's mechanicals should mirror those of the four-door as well. The A5 will likely stick with a 2.0-liter, turbocharged four-cylinder (the A4's currently makes 252 hp) and ditch the current car's eight-speed automatic transmission for a new seven-speed dual-clutch. Unlike the sedan, the coupe is likely to continue offering a six-speed manual, as it is positioned as a sportier option even if it shares the A4's platform. Front-wheel drive will be standard, while Quattro all-wheel drive will be the one to buy.
The S5 should definitely offer a manual again, along with the S4's 354-hp turbo 3.0-liter V6 and standard all-wheel drive. A seven-speed dual-clutch will be an optional extra, again, just like on the S4.
Timing of the new A5's arrival appears to have shifted. A leaked product roadmap originally called out April 2016 for the A5 and S5 hardtop and May 2016 for the Cabriolet versions. Based on the June 2 debut, it looks like Audi pushed those dates back, so we'd expect the new convertibles to make their debut sometime in July. The new A5 is pegged to arrive as a 2018 model.
We'll have all the details on the new A5 Coupe when it debuts early next month.
