Overview

The Audi A6 allroad is a five-door estate built by Audi across seven documented generations spanning 2000 to the present, with the newest generation currently in production (facelift from 2023). The lineup has consistently used all-wheel drive (AWD) and offered a spread of diesel, petrol, and high-output engine options, from four-cylinder-class displacements up to a 4.2-litre V8. Body style has remained a 5-door estate throughout the model's history.

Generations

The 1st generation ran from February 2000 to December 2005 as a 5-door estate, with 8 documented versions covering 2.5, 2.7, and 4.2-litre engines in manual and automatic form.

The 2nd generation ran from May 2006 to August 2008, offered as a 5-door estate with 6 versions, spanning 2.7-litre and 3.0-litre diesels, a 3.1-litre naturally aspirated petrol, and the 4.2 AT flagship.

The 2nd generation, restyling ran from September 2008 to March 2012, a 5-door estate with 7 versions including 2.7 and 3.0-litre diesels in manual and automatic, a supercharged 3.0 AT petrol, and the 4.2 AT V8.

The 3rd generation ran from April 2012 to November 2014, a 5-door estate with 5 versions, including 3.0-litre diesel S-tronic variants at multiple power outputs and a 3.0 S-tronic petrol.

The 3rd generation, restyling ran from December 2014 to March 2019, a 5-door estate with 5 versions: four 3.0-litre diesel S-tronic tunes plus the 3.0 S-tronic petrol.

The 4th generation began in January 2019 and is a 5-door estate with 4 versions: three 3.0 AT diesel tunes and one 3.0 S-tronic petrol.

The 4th generation, restyling 1 began in June 2023 and continues today; no individual engine versions are documented in this dataset for this facelift.

Performance and Economy

The strongest 4th-generation diesel, the 349 hp 3.0 AT, is the quickest documented version overall at 5.2 s to 100 km/h, with combined consumption of 6.6 l/100 km and CO2 at 172 g/km. The 4th-generation 340 hp 3.0 S-tronic petrol reaches 100 km/h in 5.5 s but consumes more (7.6 l/100 km combined, 174 g/km CO2). Entry-level diesels are the most efficient: the 3rd-generation-restyling 218 hp 3.0 S-tronic returns 5.6 l/100 km combined with a 149 g/km CO2 rating. The heaviest petrol flagship, the 2nd-generation-restyling 350 hp 4.2 AT, is thirstiest at 10.8 l/100 km combined, though its 0-100 time (6.3 s) is not far off newer, smaller-engined versions. Top speed is electronically limited to 250 km/h on most later high-power versions; the entry 1st-generation 2.5 MT diesel and 2.5 AT diesel have no recorded 0-100 or top-speed figures — not measured. Several earlier CO2 figures (2nd generation, most of 1st generation) are also not measured in the data.

Dimensions and Weight

Kerb weight ranges from 1760 kg (1st-generation 3.1 MT) up to 2030 kg (3rd-generation-restyling 3.0 AT diesel), with gross weight from 2390 kg to 2695 kg across the range. Ground clearance is recorded for most 1st-, 2nd- and 3rd-generation versions, ranging from 135 mm (2nd-generation-restyling and 3rd-generation versions) to 210 mm (1st-generation 2.5 AT versions); ground clearance is not measured for the 4th generation and 3rd-generation restyling versions in this dataset. Fuel tank capacity grew from 70 litres in the 1st generation to 80 litres through the 2nd and 2nd-generation-restyling cars, then down to 65 litres for the 3rd generation and 63 litres for the 3rd-generation restyling and 4th generation. Wheel sizes are not measured across the dataset.

Which Version to Choose

For outright pace with reasonable economy, the 4th-generation 349 hp 3.0 AT diesel combines the quickest 0-100 time in the range (5.2 s) with mid-pack consumption (6.6 l/100 km combined) — a 1.5-second advantage over the entry 4th-generation 231 hp 3.0 AT (6.7 s) for only 0.3 l/100 km more fuel. Buyers prioritizing efficiency should look at the 3rd-generation-restyling 218 hp 3.0 S-tronic, whose 5.6 l/100 km combined figure undercuts the flagship 4.2 AT V8 (10.8 l/100 km) by roughly half. For maximum torque, the 4th-generation 349 hp diesel's 700 Nm exceeds every V8 petrol version in the lineup, including the 440 Nm 4.2 AT — a 260 Nm difference despite the V8's larger 4163 cc displacement versus the diesel's 2967 cc. Those wanting a petrol engine with the lowest recorded consumption should note the 3rd-generation-restyling 333 hp 3.0 S-tronic at 8.0 l/100 km combined, notably better than the 1st-generation 2.7 AT petrol's 13.2 l/100 km.
