The Audi A8 60 TDI (D5, 2017+) is the thinking person's flagship limousine. Where the S8 prioritises performance, the 60 TDI prioritises effortless long-distance refinement — 286hp and 600Nm from a 3.0-litre diesel V6, a 48V mild hybrid system, and an active air suspension that reads the road 1,000 times per second. For chauffeur-driven and owner-driver buyers alike, the D5 platform offers access to the same ABT and Mansory programmes that dress the V8 models. This guide covers every meaningful upgrade available for the A8 60 TDI: body kits, wheels, engine remaps, interior refinements, and an honest assessment of where this car truly excels.
The D5 generation's clean, architectural lines reward restraint — and fortunately, the most respected tuning houses have designed programmes that enhance rather than overpower the A8's presence. Because the D5 platform is shared across all A8 variants, every major body kit fits the 60 TDI identically to the S8.
ABT Sportsline is Audi's closest partner in the aftermarket world, and their D5 programme is arguably the definitive choice for owners who want factory-adjacent quality with genuine visual improvement. The ABT A8 D5 aerokit comprises a reshaped front spoiler with integrated vertical fins, extended side skirts that visually lower the car, and a rear diffuser insert that replaces the stock lower bumper section. All components are manufactured from polyurethane with an OEM paint preparation — colour-matching is seamless. The fitment process takes under four hours at an authorised ABT dealer. Pricing runs from £4,500 for the front spoiler alone to approximately £8,000 for the complete three-piece set. ABT also offers a gloss carbon fibre mirror cap set and a boot lid spoiler as complementary additions.
Mansory's approach to the A8 D5 is more transformative: their carbon programme replaces entire exterior panels rather than adding over-the-top covers. The full Mansory D5 treatment includes a carbon fibre bonnet, front fascia with integrated LED accent strips, wide-body rear arch extensions, a multi-element rear diffuser, and a pronounced boot lid spoiler. The visual result is dramatic — the A8 reads as a bespoke creation rather than a modified production car. Mansory programmes are produced in very limited numbers and all work is carried out at the Mansory atelier in Brand, Germany. Pricing for the complete exterior programme starts at £25,000 and can reach £40,000 depending on the extent of carbon specification.
German coachbuilder Lumma Design developed the CLR 8S exclusively for the D5 generation A8. Their philosophy sits between ABT's precision and Mansory's drama: slightly wider arch shapes, a deep front spoiler with active-looking apertures, and a rear fascia that integrates the diffuser and exhaust surrounds into a cohesive unit. All CLR 8S components are produced in high-quality GRP or optional carbon fibre. Lumma's styling language is recognisably German — measured aggression rather than ostentation. European pricing ranges from €8,000 to €14,000 for the full kit depending on material choice.
Hofele Design operates from Börtlingen, Germany, and offers perhaps the most distinctive A8 D5 programme through their HF8 conversion. Hofele's signature is the wide-body option: extended wheel arches that add approximately 30mm per side, enabling genuinely wide wheel fitments without arch interference. The HF8 front fascia is a complete replacement unit with deeply sculpted lower intakes. Hofele work is bespoke by nature — pricing is available on request and every conversion is individually commissioned. Lead times run to six to eight weeks.
The A8 D5's air suspension operates through a wide range of ride heights, which places specific requirements on wheel and tyre fitment. Standard recommended sizes for the D5 platform are 21x9.5 ET25 at the 21-inch diameter, stepping to 22x10 ET20 for the maximum showroom-level statement. At 22 inches, the preferred tyre specification is 285/30 R22 — a low-profile choice that maintains correct speedometer calibration while filling the arches on standard ride height. On lowered sport suspension or with ABT spring inserts, a 275/30 R22 can provide additional clearance.
All three designs are air suspension compatible when fitted at the recommended offsets. Note that tyre pressure monitoring system (TPMS) sensors must be transferred or replaced — OEM TPMS sensors fit standard aftermarket wheels without adapters.
The 3.0 V6 diesel in the A8 60 TDI is a genuinely capable engine that leaves substantial headroom in the factory tune. Audi derates the 3.0 TDI across multiple models — the same engine architecture produces 231hp in the A6 entry tier and 286hp in the A8 60 TDI — meaning ECU recalibration can recover meaningful power without stressing the hardware.
A Stage 1 ECU remap is the most transformative single modification available for the A8 60 TDI. Reputable options include ABT's Power Upgrade, MTM's calibration, and several independent specialists. The target figures are consistent across providers: approximately 345hp and 780Nm — a 21% increase in power and 30% increase in torque. The result is a diesel torque transformation: the A8 60 TDI pulls with S8-class mid-range urgency while retaining the diesel character of effortless cruise. The 48V mild hybrid system is not involved in the main combustion tune and does not restrict remap work — the ISG unit operates independently and continues to function normally post-remap.
Stage 2 calibration pairs the ECU remap with an upgraded intercooler and high-flow air intake, targeting approximately 380hp. At this level, the ZF 8-speed transmission is typically TCU-tuned simultaneously to handle the increased torque loading. Stage 2 conversions are recommended only with fresh injector tests and a recent DSG/ZF service.
MTM (Motoren Technik Mayer) from Wettstetten, Germany, offers a Bimoto biturbo conversion for the 3.0 TDI. By fitting a second turbocharger alongside upgraded injectors and a full ECU/TCU package, MTM achieves a verified 430hp. This is exceptional for a diesel executive saloon — the A8 60 TDI with the Bimoto package matches S8 acceleration figures while retaining diesel economy at motorway speeds. The conversion requires workshop time of approximately three days and is priced accordingly.
A frequently overlooked calibration option is the economy-first remap: 286hp to approximately 320hp, optimised for minimum fuel consumption at steady-state motorway loads. Operators and fleet managers report 8-12% reductions in real-world consumption on motorway cycles. For A8 60 TDI owners who cover 30,000+ miles per year, the economy tune delivers measurable running cost savings alongside a modest power improvement.
Let us be direct: the Audi A8 60 TDI is not a track car, and attempting to make it one is the wrong question. At 2,040kg with an air suspension calibrated for luxury isolation, the D5 60 TDI on a circuit reveals its compromises quickly. The active air suspension — extraordinary on the road — struggles to maintain consistent dynamics when the dampers heat over successive corners. The brakes, sized for comfort stops rather than repeated high-speed scrubbing, fade within three hard laps. The diesel's torque delivery, so magnificent on a motorway, feels blunt at the cornering speeds a circuit requires. This is not criticism — it is architecture.
With targeted upgrades, however, the A8 TDI becomes a genuinely exceptional motorway machine. A Brembo brake upgrade addresses the fade issue for spirited road use. ABT's spring pack (-20mm drop) noticeably sharpens body control on fast A-roads without compromising the primary ride. The Stage 1 remap brings 0-100 km/h down to approximately 5.3 seconds, and the 80-130 km/h mid-range punch — that diesel torque plateau — becomes genuinely rapid. Overtaking is effortless and decisive.
Long-distance daily use is where the A8 60 TDI peaks. The Stage 1 remap improves motorway economy by 8-12% by optimising diesel injection timing at steady-state loads. A set of ABT HR22 wheels transforms the visual presence without altering the refinement. The ABT front spoiler adds a purposeful lower stance. The complete transformation — ABT aerokit, ABT wheels, Stage 1 remap — delivers a vehicle that is visually striking, faster than it looks, more economical than standard, and more comfortable than any comparable performance car.
Verdict: The ideal A8 60 TDI build is not a track weapon — it is a perfectly sorted grand tourer. ABT tune, forged wheels, and a front aerokit represent the optimum package for 95% of owners.
Yes. ABT, Mansory, and Lumma kits fit both standard and long-wheelbase A8 D5 variants identically. The wheelbase difference between A8 and A8L is entirely in the rear door and floor section — the front bumper, side skirts at the front axle, and rear bumper lower section are dimensionally identical. The only exception is Lumma's CLR 8S side skirt insert, which has separate A8 and A8L part numbers due to the longer sill on the extended model.
The 60 TDI is the stronger choice for high-mileage grand touring. Running costs on diesel are substantially lower than the 3.0 TFSI, particularly at motorway cruise speeds where diesel efficiency is most pronounced. Refinement is equivalent — both use the same air suspension, same soundproofing package, and the same ZF 8-speed. The 60 TDI is marginally slower (5.9s vs 5.7s to 100 km/h), a difference that is imperceptible in real driving. For owners covering 20,000+ km annually, the 60 TDI's economy advantage is significant over a three-year period.
No. The 48V mild hybrid on the A8 D5 uses an integrated starter-generator (ISG) belt-driven from the crankshaft. It operates as a completely independent system from the combustion engine's ECU calibration. A Stage 1 or Stage 2 remap modifies the diesel injection, turbo boost, and EGR parameters — none of which interface with the ISG control unit. Post-remap, the mild hybrid continues to function normally: coasting energy recovery, start-stop assist, and the 48V torque fill at low engine speeds all operate as standard.
This requires clarification: ABT's spring pack for the A8 D5 replaces the air suspension units rather than fitting alongside them. The two systems are not compatible — air bladder suspension and coil spring suspension are mutually exclusive architectures. If you wish to lower the A8 D5, you are converting from air to coil, which means losing the variable ride height function and the predictive active suspension. For most owners, this trade-off is not worthwhile. An alternative is an air suspension recalibration at a lower default ride height, which retains all active functionality. Consult a specialist before ordering lowering components.
