Audi e-tron GT & RS e-tron GT Tuning Guide 2026 — Body Kits, Wheels & Upgrades

The Audi e-tron GT (2021+) is a different kind of performance car — silent, instantly quick, with the proportions of a grand tourer and the battery of a serious EV. The RS e-tron GT with 646hp reaches 100 km/h in 3.3 seconds. Unlike many electric vehicles, the e-tron GT has attracted serious tuner attention from ABT, Mansory and Keyvany. This guide covers every meaningful upgrade for Audi's electric flagship.

Body Kits

The e-tron GT has a low, wide stance that rewards aerodynamic upgrades. Four serious programmes are available in 2026:

ABT e-tron GT Aerokit

ABT Sportsline — Audi's long-standing factory-adjacent tuner — offers the most refined aerokit for the e-tron GT and RS e-tron GT. The programme includes a front splitter with carbon accent trim, side skirts that extend the car's shoulder line, and a rear diffuser finished in carbon. The approach is purposeful rather than theatrical: the car reads as sporting at a glance but does not sacrifice the grand tourer balance that makes the e-tron GT distinctive. ABT also developed the HR22 forged wheel specifically for the J1 platform. Full kit price: €8,000–12,000. Fitting at an ABT-authorised workshop adds €1,500–2,500.

Mansory e-tron GT

Mansory's programme for the e-tron GT is more aggressive. The carbon fibre front bumper insert deepens the front fascia, bonnet vents add visual drama, side add-ons widen the car's profile, and the rear diffuser is a full carbon replacement. Combined, the upgrades add visible mass to the car's flanks and front end. The Mansory treatment works particularly well in solid colours — black, white, and deep red — where the carbon details contrast cleanly. Full programme price: €20,000–30,000 depending on finish and specification.

Keyvany Keystone Edition

Keyvany, based in Dubai, built its reputation on bold carbon fibre work and the e-tron GT Keystone Edition is among their strongest statements. The full programme covers bonnet with vented insert, revised front fascia, extended side skirts, rear diffuser, and a rear spoiler. Every panel is dry carbon fibre — not wrapped but manufactured. The Keystone Edition is sold on a limited and bespoke basis, making it the most exclusive e-tron GT body package available. Pricing is on application; the programme is particularly popular across the GCC and UAE market.

Prior Design PD e-tron

Prior Design offers the accessible entry point into e-tron GT body styling. The PD kit comprises a front lip spoiler, side skirts, and rear diffuser in high-flex polyurethane — a material that survives low-speed contact better than carbon. The Prior Design approach suits owners who want presence without track-focused rigidity. Pricing: £3,500–6,000 for the full kit before fitting.

Wheels

Stock e-tron GT wheels run 20–21 inch across the range. The car's staggered setup — fronts narrower than rears — is carried over from the Porsche Taycan and is a critical detail when specifying replacements.

Target fitment (tuning sizes):

• Front: 21×9.0 ET20 / 265/35 R21
• Rear: 22×9.5 ET15 / 255/30 R22

Recommended wheels for e-tron GT:

• ABT HR22 — 22-inch forged, designed specifically for the J1 platform. Correct offsets confirmed for e-tron GT and Taycan. ABT's lightest e-tron GT option.
• HRE P101 — 21-inch one-piece forged. American manufacture, available in a wide range of custom finishes. Verified J1 fitment available.
• Vossen HF-5 — multi-piece, 22-inch. Flow-formed centre with forged outer barrel. High visual complexity, strong on dark and white car colours.

Tyre note: low rolling resistance matters on an EV — tyre choice affects real-world range by 5–10%. Continental SportContact 7 and Pirelli P Zero E are the leading choices for performance + range balance. Avoid high-performance summer tyres without EV load ratings.

Performance Upgrades

The e-tron GT runs on a locked ECU, and Audi's software architecture is deliberately resistant to third-party intervention. Software tuning options are limited compared with ICE vehicles, but targeted hardware upgrades remain viable.

ECU / Power: ABT offers a power upgrade for RS e-tron GT on select early production builds: 646 hp → 700 hp. This is hardware-assisted rather than a pure remap. Not universally available across all model years — verify with ABT directly before ordering. Most other tuners focus entirely on non-powertrain work.

Suspension: ABT lowering springs drop ride height by 20 mm, sharpening turn-in and improving visual stance. The e-tron GT's adaptive air suspension means spring rates need to be chosen with care — ABT's kit is calibrated for the stock air system. Aftermarket coilovers for J1 are limited.

Brakes: Brembo GT6 caliper kit for improved heat management and pedal feel during track use. The factory brakes on the RS e-tron GT are capable for road use; GT6 is primarily for owners who take the car to circuit days.

Sound: The RS Sound Package (factory Audi option) uses resonators to generate an interior and exterior acoustic signature. Aftermarket resonator upgrades are available for RS owners who find the factory sound insufficient. There is no exhaust system to replace — the car produces no combustion exhaust.

Note: for maximum return on investment, the priority order for e-tron GT upgrades should be: aero → wheels → interior → suspension → power. Power tuning on the e-tron GT delivers the smallest marginal gain relative to cost.

Interior

The e-tron GT's interior is already one of the better cabin environments in the performance segment — well-built, tech-focused, with quality materials. Upgrades tend to amplify what's already there rather than correct deficiencies.

• Alcantara headlining — replaces the standard cloth headliner. Reduces cabin noise perception and adds tactile quality. Available factory on RS Vorsprung spec; aftermarket otherwise.
• Nappa leather RS Sport seats — the RS Sport seat is the most lateral-support-focused factory option. Aftermarket Recaro or Sparco seats are available for track owners.
• Carbon trim package — available factory on RS Vorsprung and as Audi Exclusive options. Aftermarket carbon dash inserts and door panel trim available from Mansory and independent suppliers.
• Mansory full interior refit — bespoke Alcantara and leather combination throughout, embroidered headrests, custom Alcantara steering wheel. Priced on application.
• MMI touchscreen upgrades — Android Auto wireless adapters, screen protectors. Limited aftermarket modification possible given OTA update architecture.

What Actually Changes After Tuning

Honest before/after assessment for the e-tron GT after ABT Aerokit + 22-inch wheels + lowering springs (approximately €16,000 all-in at time of writing):

Appearance: the stock e-tron GT is elegant but genuinely understated — many people mistake it for a large Audi A7. With the ABT front splitter, side skirts, and 22-inch HR22 wheels, the car reads as a supercar at a distance. People stop to photograph it in car parks. The standard car is admired up close; the ABT version is noticed from 50 metres. This is the most significant practical change in the programme.

Sound: the e-tron GT is near-silent at low speed — this does not change with wheel or aero upgrades. The RS Sound Package creates a generated acoustic signature inside and outside the car. It adds character without replicating an ICE note. There is no exhaust note to upgrade; owners who need a combustion soundtrack should consider this before purchase rather than after.

Driving feel: ABT's 20 mm lowering sharpens initial turn-in noticeably. The stock e-tron GT handles well on its adaptive air suspension — the springs add a degree of precision rather than transforming the character. Ride comfort changes minimally in comfort mode; the reduction is more noticeable in dynamic mode on rough surfaces.

Social response: the electric GT aesthetic divides opinion in different markets. Mansory and Keyvany kits are received enthusiastically in the UAE and Gulf region; reactions in Germany and the UK are more varied. ABT's understated aerokit is universally respected across markets.

Practical considerations: 22-inch wheels add a marginal increase in road noise at motorway speeds. Tyre replacement costs increase significantly — budget €2,000–3,000 per axle for premium EV-rated rubber. Range is unaffected by wheel and aero changes in normal driving.

Frequently Asked Questions

Does the e-tron GT share wheels with the Porsche Taycan?

Yes — both use the J1 platform and many wheels manufactured for the Taycan will physically fit the e-tron GT. However, wheel offset and load ratings vary between model years and trim levels. Always verify offset specifications with the wheel manufacturer before ordering, particularly for staggered fitments.

Can e-tron GT software be tuned to increase power?

Options are limited. ABT offers an increase of approximately 54 hp on the RS e-tron GT (646 → 700 hp) on select early production vehicles via a hardware-assisted upgrade. For standard e-tron GT models and later RS builds, no verified power software upgrade is available from a mainstream tuner. The ECU architecture is locked and Audi's OTA update system monitors for modification. Most tuners direct e-tron GT clients toward aero, wheels, and interior work.

What is ABT's aerokit price all-in including fitting?

The ABT e-tron GT Aerokit is priced at €8,000–12,000 for components, depending on carbon versus standard finish options. Fitting at an ABT-authorised workshop typically adds €1,500–2,500 depending on location and workshop rates. Total budget: €9,500–14,500 all-in. Import duties and shipping apply for customers outside Germany/EU.

Is the e-tron GT a good track day car?

The e-tron GT is capable on a circuit — the chassis is well-sorted, brakes are strong, and the performance is immediate. The constraint is range: at track pace, usable range drops to approximately 150–200 km depending on ambient temperature and circuit layout. Repeated heavy braking can saturate the regeneration system. For occasional circuit visits the e-tron GT performs well; for regular track use, plan charging logistics carefully and consider the Brembo GT6 brake upgrade.
