Where do these Audi S5 figures come from?

They're worked out from current used-Audi S5 listings in Singapore — asking prices, mileage and registration years — not past transaction prices. We refresh them regularly, and we flag thin data rather than guess.

Tap any dot on the chart to see its scores.

Brand reliability: Consumer-survey composite — JD Power · WhatCar · Consumer Reports. Same score for every variant of a given make.
Resale strength: 100 − 3× annualised tangible-decay (COE-stripped). Fitted from each variant's asking-price-by-age regression then averaged at model level.
Peer set: Every same-segment model with ≥5 active PARF listings whose variants fit a depreciation curve. Practicality isn't plotted — it's a body-shape constant within the segment, so it would be the same for every dot.
Quadrants: The crosshair marks the segment median on each axis. Top-right (Safe Bets) is strong on both; top-left (Hidden Gems) holds value above what the brand reputation suggests; bottom-right (Bargain Buys) is well-built but depreciates fast — buy cheap; bottom-left (High Risk) is soft on both.

Verdict

Cult-buy performance trim of the A5 8T — V8 4.2L (BNS/CFSA) on pre-2012 cars, then 3.0 TFSI EA837 supercharged V6 (post-2012). The V8 4.2L is the bulletproof cult engine (one of Audi's last great NA V8s — same family as RS4 B7). 3.0 TFSI EA837 introduces water pump + supercharger oil leak patterns. 7-speed DSG (DL501 wet 7-speed) on EA837 cars is well-regarded. S5 chassis durability is good when serviced; aged-car items dominate at 9-18 years now.

What's good

Pre-2012 V8 4.2L (BNS/CFSA) with documented service — one of Audi's last great NA V8s (same family as RS4 B7). Bulletproof when serviced; the cult-buy V8 era of the S5. SG penalty: higher fuel + road tax.
Post-2012 3.0 TFSI EA837 with documented supercharger + water pump receipts — the supercharger oil leak + water pump failures are documented; receipts for both convert the recurring concerns to non-issues. Same DSG (DL501) discipline as broader Audi family.

What to watch

3.0 TFSI (EA837) leaking supercharger oil or losing coolant — documented supercharger seal + water pump failure patterns. S$3-5k for proper repair; budget if undocumented.
V8 4.2L with a history of rod-bearing knock or low oil pressure — same scheduled-maintenance item as the broader V8 lineage. Catastrophic when bearings fail; full rebuild well into 5 figures. Walk unless heavily discounted with paperwork.
