2026 Audi RS5 price and specs

Audi’s new BMW M3 and Mercedes-AMG C63 rival is heading to Australia, with a price tag that undercuts its fellow Germans.

The new Audi RS5 sedan and wagon range, which replaces the old RS4 sedan, RS4 Avant and RS5 Sportback, is due in Australian showrooms in the second half of 2026.

The RS5 Sedan is priced at $179,900 before on-road costs, while the RS5 Avant costs $182,900 plus on-roads.

That makes the RS5 cheaper than the Mercedes-AMG C63 ($195,300 plus on-roads) which is also a plug-in hybrid (PHEV) sedan but with two fewer cylinders, and sees it narrowly undercut the most affordable automatic BMW M3 sedan ($186,900 plus on-roads), which also has a six-cylinder engine but no PHEV system.

Like its predecessor, it uses a twin-turbocharged 2.9-litre petrol V6. However, this engine has been overhauled and is now mated with a PHEV system, and total outputs are up by 139kW and 225Nm to 470kW/825Nm.

Weight is up, too. The RS5 Sedan, which is actually a five-door liftback, weighs 2355kg and the Avant weighs an extra 15kg. In contrast, the old RS5 Sportback weighed 1835kg and the RS4 Avant 1895kg.

The RS5 is easily distinguished from lesser A5 and S5 models, only sharing its roof, front doors, and tailgate with its more affordable siblings.
