Ranked #132 car in the UK · Estate · 3,410 units sold last year

Audi A6 Avant

The C8 Audi A6 Avant (2018 on) is the polished executive estate - a long, low and beautifully-built load-lugger that pairs A8 levels of cabin tech with a genuinely useful boot. UK cars are mild-hybrid petrols and a 50 TFSI e plug-in hybrid, all with quattro. It trades the sharper handling of a 5 Series Touring for outright comfort, refinement and one of the quietest cabins in the class - a classy, quietly capable motorway estate that holds its money on badge strength.

Petrol, diesel, hybrid or EV?

How the available versions compare on price, running cost, and the headaches each tends to develop.

Petrol

The default choice: lowest purchase price and easy upkeep, at the cost of higher fuel bills than a hybrid.

New price: £45,900
Annual fuel / energy: £1,445
3-yr depreciation: 51%

Watch for

·Carbon build-up on direct-injection engines
·Ignition coils and spark plugs with age
·Cam or wet-belt service where fitted

Diesel

Makes sense for high motorway mileage; less so for short urban hops, where the DPF struggles.

New price: £49,100
Annual fuel / energy: £1,428
3-yr depreciation: 54%

Watch for

·DPF clogging on mostly-short journeys
·EGR valve and turbo wear with mileage
·AdBlue system upkeep on newer engines

Reliability

70/ 100

Good

Composite of MOT pass rate, defect prevalence and cohort survival from 212 tests — low confidence.

MOT outlook

Insufficient MOT history at this car's reference age — too few tests to compute a reliable percentile.

Things owners say

01The mild-hybrid petrols suit those who can't charge; the 50 TFSI e PHEV adds low-BIK electric miles.
02A square, usefully large boot and a hushed cabin are the estate's strong cards.
03The dual-touchscreen MMI looks smart but is fiddlier on the move than physical controls; check DSG fluid history.

Safety recalls

Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Audi A6 Avant, or your exact vehicle, has any outstanding recalls on the official DVSA service.

Check on GOV.UK

Opens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.

Theft risk

A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.

Whole-car theft

Higher

Higher-value cars like this are relay-theft targets — keyless entry can be exploited from the driveway in under a minute.

Parts theft

Higher

Hybrid versions are a catalytic-converter target — a hybrid cat is rich in precious metals and can be cut out in about a minute.

Worth doing

Keep keys in a Faraday pouch and away from the front door to block relay attacks.
A catalytic-converter guard or forensic marking makes a hybrid far less appealing to cut.
A visible steering lock is a cheap, strong deterrent on a frequently-targeted car.

Clean-air zones

Whether driving a Audi A6 Avant into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.

Charging zones for cars

City	Area	Daily charge	Likely outcome
London	All of Greater London (within the M25)	£12.50	Likely exempt Hybrid petrol engines from 2006 meet Euro 4.
Birmingham	Inside the A4540 Middleway	£8.00	Likely exempt Hybrid petrol engines from 2006 meet Euro 4.
Bristol	City centre and part of the Portway	£9.00	Likely exempt Hybrid petrol engines from 2006 meet Euro 4.
Glasgow	City centre	—	Likely exempt Hybrid petrol engines from 2006 meet Euro 4.
Edinburgh	City centre	—	Likely exempt Hybrid petrol engines from 2006 meet Euro 4.
Aberdeen	City centre	—	Likely exempt Hybrid petrol engines from 2006 meet Euro 4.
Dundee	City centre	—	Likely exempt Hybrid petrol engines from 2006 meet Euro 4.

Zones that don't charge private cars

Bath — City centre (Private cars and motorbikes are not charged).
Bradford — Outer ring road and the Aire Valley (Private cars are not charged).
Sheffield — Inside the A61 inner ring road (Private cars are not charged).
Newcastle & Gateshead — City centres and the Tyne, Swing, High Level and Redheugh bridges (Private cars are not charged).
