Audi A6 Review 2025

Barely a month after the latest generation of estate-bodied Audi A6 Avant was revealed, its more traditionally shaped sibling has been unveiled in the form of the all-new Audi A6 Saloon.

Reflecting the greater importance for Audi of estate car sales compared with those of the four-door saloon A6, their appearance in that order is contrary to the approach of the brand’s two key rivals — both the BMW 5 Series and Mercedes E-Class were released the opposite way around.

Further alternatives to the Audi A6 are smaller in number than they were even just a few years ago as other manufacturers have either abandoned the upmarket saloon market altogether or, such as Volvo, have gone electric-only with their offerings.

Small numbers of the petrol-fuelled Genesis G80 remain available, while the self-charging hybrid-powered Lexus ES is expected to be replaced by an all-new design within the next year.

Talking of electric models, this new Audi A6 Saloon — powered by both petrol and diesel engines, with varying levels of hybridisation — isn’t to be confused with its EV sibling, the Audi A6 Sportback e-tron. Originally, that overlap wouldn’t have happened as the combustion-engined cars were set to be badged A7 until a last-moment change of plan.

As with the estate version, two engines will be available from the get-go in the Audi A6 Saloon. Both have 2.0-litre capacities producing 204PS and are equipped as standard with seven-speed S Tronic dual-clutch automatic gearboxes.

With maximum torque of 340Nm, the front-wheel drive TFSI petrol version sprints from 0-62mph in 8.2 seconds, continuing on to a maximum of 151mph. More buyers are expected to be tempted by the TDI diesel, complete with MHEV Plus mild hybrid assistance and enhanced traction thanks to its Quattro four-wheel drive system. Thanks to 400Nm of torque, this A6 reduces the 0-62mph yardstick to 6.9 seconds, although top speed drops ever so slightly to 150mph.

Towards the end of 2025 or early 2026, the range of drive systems will increase with the introduction of TFSI e-labelled plug-in hybrids as well as a replacement for the punchier Audi S6 models.

Audi’s familiar triumvirate of trim levels are present and correct with the latest A6 Saloon from launch, with both engine choices available with Sport, S Line and Edition 1 grades. It’s the sportier-than-Sport S Line that’s expected to prove the most popular.

It’s no surprise that the latest Audi A6 Saloon shares the Avant’s passenger compartment, including the Softwrap dashboard and door panel design, the former incorporated up to three display screens. The third is for the front seat passenger and is standard on Edition 1 versions, optional on the less expensive trims.

Saloons are inherently less practical than estate versions of the same design, so Audi’s given the A6 a 40:20:40 split-folding rear seatback and an electrically operated boot lid to maximise its flexibility potential.

Audi quotes the A6 Saloon’s boot capacity at a maximum of 492 litres, a figure that’s just 11 litres shy of the Avant’s available space when loaded to the luggage cover. We suspect that’s for the TFSI petrol version, though — the TDI’s MHEV Plus system and driven rear wheels mechanicals nibble a further 47 litres away from the A6 Avant’s luggage volume, so expect a similar reduction for the Saloon.

Compared with its core rivals, the A6 Saloon lags behind. Mild and plug-in hybrid-equipped BMW 5 Series Saloons have 520-litre boot while the Mercedes E-Class Saloon’s capacity is quoted at 540 litres for mild hybrids and 370 litres when PHEV-propelled.

Order books for the new Audi A6 Saloon open on 15 May 2025 with prices starting at £50,560 for the Sport TFSI 204PS S Tronic peaking at £62,530 for the Edition 1 TDI Quattro 204PS S Tronic. First customer deliveries are expected in July.
