Audi SQ8

Audi SQ8: which version to buy and why

The Audi SQ8 in this catalogue is a five-door SUV with one generation on record, produced from 2019-01-01, and a restyling of that same generation from 2023-09-01 that is still listed without a stop date. The buying choice is not “which generation number,” because restyling 1 sits inside generation 1.

The Audi SQ8 in this catalogue is a five-door SUV with one generation on record, produced from 2019-01-01, and a restyling of that same generation from 2023-09-01 that is still listed without a stop date. The buying choice is not “which generation number,” because restyling 1 sits inside generation 1. The choice is which 4.0 AT (or the restyled 4.0 TFSI AT) matches the job: peak horsepower, diesel torque, or the later 507 hp gasoline layout.

There are four catalogue versions. Three share the name 4.0 AT and must be told apart by power: 4.0 AT 435 hp (Diesel), 4.0 AT 600 hp (Gasoline), and 4.0 AT 507 hp (Gasoline). The restyling uses a different exact name: 4.0 TFSI AT 507 hp (Gasoline). All four are Automatic, 8 gears, AWD, Turbo, V-shaped 8 cylinders, 4 valves per cylinder, front longitudinal engine, Euro 6, top speed 250. Body type is SUV 5-doors throughout.

Generations (and the restyling inside generation 1)

1 generation (2019-01-01 to 2024-01-31), SUV 5-doors, 3 versions. This is the only generation that offers a Diesel option. 4.0 AT 435 hp runs the full window 2019-01-01–2024-01-31. Both Gasoline 4.0 AT versions (600 hp and 507 hp) start later, 2020-01-01–2024-01-31. Front suspension is Independent, spring; rear is Independent, pneumatic. Brakes are Ventilated disc front and Disc ventilated rear.

1 generation, restyling 1 (from 2023-09-01, stop not measured), SUV 5-doors, 1 version. This is not a second model family. It is the same generation with one listed powertrain: 4.0 TFSI AT 507 hp. Displacement moves from 3956 to 3998. Fuel system is listed here as Direct injection (direct); the three pre-restyle versions have fuel system not measured. Rear suspension changes from Independent, pneumatic to Independent, spring. Front stays Independent, spring. Peak torque drops from 800 Nm on both Gasoline 4.0 AT versions to 770 Nm. 0–100 is measured at 4.1; kerb weight, gross weight, tank, CO2, city/highway/mixed consumption, compression, and bore × stroke are not measured.

Overlap: restyling 1 starts 2023-09-01 while generation 1’s stop is 2024-01-31, so both the 3956 4.0 AT set and the 3998 4.0 TFSI AT exist in the same late window in this dataset.

Engine specs: four versions, two names

Engine size in the first generation is the same 3956 for Diesel and Gasoline. Restyling 1 is 42 larger at 3998 (3998 − 3956). Cylinder count and V-shaped layout do not change.

Power per litre (hp ÷ displacement in litres): 4.0 AT 435 hp = 435 ÷ 3.956 ≈ 110.0 hp/L. 4.0 AT 507 hp = 507 ÷ 3.956 ≈ 128.2 hp/L. 4.0 AT 600 hp = 600 ÷ 3.956 ≈ 151.7 hp/L. 4.0 TFSI AT 507 hp = 507 ÷ 3.998 ≈ 126.8 hp/L — slightly less specific output than the pre-restyle 507 hp 4.0 AT because displacement is 42 larger at the same 507 hp.

Horsepower gaps: 600 − 435 = 165 hp (and 441 − 320 = 121 kW) between the Diesel 4.0 AT and the strongest Gasoline 4.0 AT. 600 − 507 = 93 hp (441 − 372 = 69 kW) between the two Gasoline 4.0 AT versions. The restyled 4.0 TFSI AT matches the 507 hp / 372 kW of the weaker Gasoline 4.0 AT, not the 600.

Torque is the Diesel argument: 4.0 AT 435 hp has 900 Nm, which is 100 Nm more than the 800 Nm of both Gasoline 4.0 AT versions (900 − 800). Restyling 1’s 4.0 TFSI AT is 770 Nm, 30 Nm below those 800 Nm Gasoline 4.0 AT figures (800 − 770) and 130 Nm below the Diesel (900 − 770). The Diesel also delivers that 900 Nm across 1250–3250, while Gasoline 4.0 AT torque is listed at a single 2200 point. Compression: Diesel 4.0 AT 16 versus Gasoline 4.0 AT 10 (difference 6). Bore × stroke: Diesel 83 × 91.4 versus Gasoline 4.0 AT 86 × 86; restyle bore × stroke not measured.

Searches for “Audi SQ8 e-tron” do not map to any version in this dataset: fuel is Diesel or Gasoline 95 only.

Performance, mpg-style consumption, 0–100

Measured 0–100: 4.0 AT 600 hp 3.8; restyled 4.0 TFSI AT 507 hp 4.1; 4.0 AT 435 hp Diesel 4.8. 4.0 AT 507 hp 0–100 is not measured. Arithmetic on the measured three: the 600 hp 4.0 AT is 1.0 s quicker to 100 than the Diesel (4.8 − 3.8) and 0.3 s quicker than restyling 1 (4.1 − 3.8). Restyling 1 is 0.7 s quicker than the Diesel (4.8 − 4.1). Top speed is 250 on every version; extra horsepower does not raise the listed ceiling.

Consumption is only fully measured on the Diesel 4.0 AT: city 8.6, highway 7.3, mixed 7.8. The 600 hp 4.0 AT has mixed 12.1; city and highway not measured. Mixed gap: 12.1 − 7.8 = 4.3 more on the 600 hp Gasoline 4.0 AT than on the Diesel 4.0 AT. 4.0 AT 507 hp and 4.0 TFSI AT consumption (city, highway, mixed) are not measured. CO2 is 205 on all three generation-1 4.0 AT versions; restyling 1 CO2 is not measured.

If the buying criterion is the shortest measured 0–100, the answer is 4.0 AT 600 hp at 3.8. If the criterion is the lowest measured mixed figure, the answer is 4.0 AT 435 hp at 7.8. If the criterion is restyling hardware with a measured 0–100, the only option is 4.0 TFSI AT at 4.1 — not the 600 hp 4.0 AT, which stops 2024-01-31 and is not listed in restyling 1.

Dimensions, weight, tank, clearance

Wheel sizes: not measured on all four versions. Ground clearance: not measured on all four. Tank: 85 on all three 4.0 AT versions; 4.0 TFSI AT tank not measured.

Measured kerb / gross: Diesel 4.0 AT 2365 / 3100. Gasoline 4.0 AT 600 hp 2315 / 3015. 4.0 AT 507 hp and 4.0 TFSI AT: kerb and gross not measured.

Weight arithmetic where both sides exist: the Diesel 4.0 AT is 50 kg heavier at kerb (2365 − 2315) and 85 kg heavier at gross (3100 − 3015) than the 600 hp 4.0 AT. Kg per horsepower: Diesel 2365 ÷ 435 ≈ 5.44 kg/hp; 600 hp 4.0 AT 2315 ÷ 600 ≈ 3.86 kg/hp. The 600 hp version carries 1.58 kg less per horsepower (5.44 − 3.86). Payload-style spread (gross − kerb): Diesel 3100 − 2365 = 735 kg; 600 hp 4.0 AT 3015 − 2315 = 700 kg — Diesel has 35 kg more on that difference.

Without measured kerb on 4.0 AT 507 hp and 4.0 TFSI AT, weight-per-horsepower cannot be computed for those two; it is not measured, not “the same as 600.”

Which version to choose

Choose 4.0 AT 435 hp (Diesel, 2019–2024) when the numbers that matter are torque and measured economy. It is the only Diesel, the only version with 900 Nm, the only version with city 8.6 / highway 7.3 / mixed 7.8, and the only one with 0–100 measured among the 2019 starters. You give up 165 hp versus 4.0 AT 600 hp, 1.0 s on 0–100 (4.8 versus 3.8), and you carry 50 kg more kerb. Specific output is the lowest at ~110.0 hp/L. Peak power arrives earlier (3750–4750) than the Gasoline 4.0 AT peak at 6000. It is also the only version whose production window includes all of 2019 in this file.

Choose 4.0 AT 600 hp (Gasoline, 2020–2024) when the numbers that matter are horsepower, specific output, and the shortest 0–100. 600 hp / 441 kW, ~151.7 hp/L, 3.8 to 100, lightest measured kerb at 2315, lowest measured kg/hp at ~3.86. Versus the Diesel you pay 4.3 on mixed (12.1 versus 7.8) and lose 100 Nm (800 versus 900). Versus 4.0 AT 507 hp you gain 93 hp at the same 800 Nm, same 3956, same 95 fuel, same 8-speed Automatic AWD; 0–100 for the 507 hp twin is not measured, so you cannot claim a seconds gap there from this file. This version does not appear in restyling 1.

Choose 4.0 AT 507 hp (Gasoline, 2020–2024) only with eyes open about what is not measured: 0–100, all consumption, kerb, gross. On paper it sits between the other two 4.0 AT names: 507 hp is 72 hp above the Diesel (507 − 435) and 93 hp below the 600 (600 − 507), with Gasoline 800 Nm like the 600, not Diesel 900. Compression 10 and 86 × 86 match the 600 hp 4.0 AT, not the Diesel. If a listing uses the bare name 4.0 AT, confirm 507 versus 600 versus 435 by horsepower — the name alone does not identify it.

Choose 4.0 TFSI AT 507 hp (restyling 1, from 2023-09-01) when the restyling package is the point: 3998 instead of 3956, Direct injection (direct) listed, rear Independent, spring instead of Independent, pneumatic, and a measured 4.1 0–100. You do not get the 600 hp figure; restyling 1 lists 507 hp / 372 kW and 770 Nm, 30 Nm below both Gasoline 4.0 AT versions. Versus pre-restyle 4.0 AT 507 hp, power matches (507 / 372) while torque is 30 Nm lower and displacement is 42 higher, so specific output falls from ~128.2 to ~126.8 hp/L. Tank, CO2, consumption, and mass are not measured — do not treat them as equal to 85 / 205 / 12.1 / 2315.

What the “extra” buys, in numbers only (no prices in this dataset). Extra 165 hp from Diesel 4.0 AT to 4.0 AT 600 hp buys 1.0 s on 0–100, 50 kg less kerb, ~41.7 hp/L more specific output (151.7 − 110.0), and costs 100 Nm and 4.3 mixed. Extra 93 hp from 4.0 AT 507 hp to 4.0 AT 600 hp buys peak power and a measured 3.8; torque stays 800. Moving from any 4.0 AT to 4.0 TFSI AT buys the restyle name, 3998 cc, listed direct injection, spring rear axle, and 4.1 0–100; it does not buy 600 hp or 900 Nm.

Reliability / problems / engine oil / engine code / dimensions (length/width) / 2025–2026 hp: not measured in this file. Used versus new is not a spec here — only production windows. For sale and price are not in the data.

Short rule: three 4.0 AT badges — pick 435 for 900 Nm and 7.8 mixed, 600 for 3.8 and 600 hp, 507 only if you accept 0–100 and weight not measured. One restyle badge — 4.0 TFSI AT — pick it for 3998 / 4.1 / restyling 1, not for more power than 507.
