2025 Audi A6 Avant Unveiled as Brand’s New ICE-Powered Estate

The all-new 2025 Audi A6 Avant breaks cover as the brand’s next-gen flagship estate, featuring both petrol & diesel engines.

Audi has not given up entirely on its combustion-powered lineup, as the brand reveals its next-gen ICE-powered flagship estate, the 2025 Audi A6 Avant. Available in both petrol and diesel forms, the new A6 Avant is also one of the remaining few diesel-powered wagons left on the market.

Not to be confused with the recently launched A6 e-tron Avant, the new A6 Avant is born from the German marque’s decision to revert its split ICE and BEV model naming scheme. While both models boast no mechanical similarities, these models share the same duty of being the brand’s new flagship estate models, offering consumers a choice of either an ICE powertrain or a fully electric one.

Back to the new A6 Avant, this sleek wagon gets a whole design makeover for its next-gen iteration, featuring a fiercer look compared to its all-electric twin, while growing 60 MM longer than its predecessor. Some key design features include sharp LED digital headlights and taillights with multiple light signatures, a larger front grille and lower bumper intakes, and a sleeker bodystyle with flushed door handles, to name a few.

Its sleek silhouette and larger air intakes aren’t just for show, as Audi claims they helped the new A6 Avant to be more slippery. Combined with other aerodynamic bits like the rear diffusers and underbody covers, the new A6 Avant boasts a low drag coefficient rate of only 0.25 Cd, thus making it the brand’s most aerodynamic ICE-powered estate.

However, the title for the most slippery Audi wagon still goes to its BEV twin, which gets a more impressive drag coefficient of only 0.24 Cd.

Jump inside the new A6 Avant, and you’ll find a pretty posh and well-equipped cabin, so much so that Audi even promises it will deliver “first-class travel like no other vehicle in its class.”

Some key tech amenities primed here include Audi’s signature MMI display setup featuring a third display for the front passenger, power-adjustable sporty front seats, a multi-colour ambient lighting system, a four-zone climate control with dedicated rear vents, an adjustable panoramic glass roof, a premium Bang & Olufsen audio system, and many more.

But what really sells us on the “first-class travel experience” Audi promises is the fact that the new A6 Avant is offered with an optional adaptive air suspension system that combines sportiness with comfort. Audi engineers have also increased the front camber of this estate, while the all-wheel steering system and its Premium Platform Combustion (PPC) architecture underpinning all ensure that the new A6 Avant is still magical to drive.

Moving on to the powertrain options, the new A6 Avant will be initially offered in three engine options, featuring both petrol and diesel versions for customers to choose from. The petrol lineup starts with the baseline 2.0-litre 4-cyl TFSI engine rated at 201 HP that is now mated to a 48-volt mild hybrid (MHEV) system, adding an extra 23 HP and 230 Nm of twist, as well as a regenerative braking function to this estate.

Meanwhile, the top-spec petrol variant gets a peppier 3.0-litre straight-six TFSI engine rated at 362 HP, which is also benefiting from said MHEV setup. Despite sharing the same power plant as the new S5, this variant of the A6 Avant does not carry the S badge, so we can expect more peppier variants to arrive in the future.

The sole diesel-powered option, on the other hand, uses a 2.0-litre 4-cyl TDI lump that produces 201 HP before the electrification assist. Given that Audi has yet to launch a plug-in hybrid (PHEV) variant for the estate (for now), the TDI model is easily the best choice for frugal owners.

Besides the three variants, Audi’s new A6 Avant lineup is about to grow bigger in the near future, as the automaker already confirmed that both the rugged A6 Allroad and performance-focused RS6 variants will arrive soon, but at least not before its sedan twin arrives.

Interestingly, despite all the aforementioned improvements, the new Audi A6 Avant is actually cheaper than its predecessor, with prices starting from €58,000 (RM273,804) in Germany for the baseline TFSI petrol variant. Deliveries for the new A6 Avant are scheduled to begin later in May this year, although we’re uncertain on whether this sleek estate will be available beyond the Old Continent’s border.
