Used Audi RSQ5 Buying Guide
A quick word on the badge first: Audi has never sold a factory RS Q5 in the UK. Cars advertised as an “RSQ5” are almost always the SQ5 — the genuine performance flagship of the Q5 range — or a standard Q5 fitted with RS-style styling parts such as a black-optic grille and RS-look bumpers. That’s worth knowing before you view anything, because it affects both what you should pay and what you’re actually getting. Treated as a guide to the hot Q5, though, there’s plenty to like: the SQ5 blends serious pace with quattro four-wheel drive and everyday family-SUV usability.
Engines and trims
The first-generation SQ5 (2013–2017) was unusual in being diesel-powered in the UK: a 3.0-litre BiTDI V6 with muscular mid-range shove and surprisingly reasonable economy for the performance. The second-generation car launched in 2017 with a 3.0-litre TFSI turbo petrol V6, then switched back to a 3.0 TDI V6 with mild-hybrid assistance from around 2019, before petrol returned on the latest generation. All use automatic gearboxes and quattro drive.
Which to pick depends on use: the petrol TFSI is the sweeter, freer-revving engine, while the TDI versions suit high-mileage drivers who want long-legged pace with better fuel economy. Equipment is generous on all SQ5s, with Vorsprung and Black Edition versions adding items such as matrix LED lights, upgraded audio and larger wheels. Air suspension and adaptive dampers appear on many cars — desirable, but budget for their upkeep. If a car is genuinely advertised as an RS Q5, ask the seller exactly what has been modified and by whom.
What to check before buying
Provenance matters more than usual here. Verify the exact model on the V5C, and if RS-style parts are fitted, check the quality of the conversion and whether insurers have been told. On any performance Q5, a full service history — ideally with evidence of frequent oil changes — is essential, as these are complex, heavily stressed drivetrains.
On BiTDI diesels, listen for smooth running from cold and check the DPF and AdBlue systems behave on cars that have lived in town. On air-suspended cars, look for one corner sitting low after being parked overnight and listen for compressor noise. Big brakes and 20-inch-plus wheels are costly consumables, so inspect disc lips, pad wear and tyre condition — mismatched budget tyres on a 350-plus-horsepower SUV are a red flag. Check for uneven tyre wear that might indicate alignment or suspension arm wear, a known consideration on heavier fast Audis as miles climb.
Running costs
Expect proper performance-car running costs in an SUV wrapper. The petrol V6 will be the thirstiest in everyday use, while the diesels are noticeably more frugal on a motorway run, though neither is cheap to fuel. Insurance sits in the upper groups, servicing at specialist or main-dealer rates is dearer than a standard Q5, and consumables — tyres, brakes, suspension components — wear faster and cost more. Road tax can also be significant on cars first registered with a high list price. Budget realistically rather than stretching to the purchase price alone.
Verdict
There’s no factory RS Q5, so shop for a good SQ5 and be sceptical of RS badging. Buy on history and condition rather than spec sheet, favour cars with evidence of caring ownership, and the SQ5 rewards with a rapid, refined and usable family SUV.
