A plug-in hybrid powertrain with an electric-only range of 62 miles will follow next year.

Autocar understands the PPC can also support range-extender EV powertrains, but Audi doesn’t have plans to offer one in the A5.

The new platform also means the saloon has grown significantly, becoming 67mm longer (at 4.83m) and 13mm wider (at 1.86m). Its wheelbase is 68mm longer too (at 2.9m), Audi having prioritised interior space.

Visually, the A5 is clearly an evolution of the A4, with a smooth-edged design that borrows cues from the A6 E-tron saloon EV concept shown three years ago. Key to the look are flared wheel arches that the designers refer to as ‘Quattro muscle’.

The new OLED front and rear lights can display eight patterns apiece and have a Dynamic mode that continually changes what’s displayed.

The A4’s false exhaust tips have been ditched in response to customer feedback.

Inspired by the Q6 E-tron, the interior has a large curved display serving as the focal point on the dashboard. It’s split into an 11.9in digital instrument panel and a 14.5in infotainment touchscreen.

The latter hosts the climate controls and functions such as seat heating and ventilation.
