Our review of the Audi RS e-tron GT
The RS e-tron GT is the high-performance version of the e-tron GT — and the most powerful production car Audi has ever built. In overboost mode it puts out 856 hp and dispatches 0-100 km/h in 2.8 seconds. DC charging peaks at 320 kW: 10 to 80% in 15 minutes on an Ionity HPC. The real-world range figure is 455 km. At €165,000 this is a very targeted proposition: a top-tier electric grand tourer for a driver whose car budget isn't the main constraint.
Driving & comfort
On the E40 motorway at 130 km/h the RS e-tron GT is quiet, stable, with a remarkably effective adaptive air suspension. In Comfort mode it's a relaxed grand tourer that handles Brussels–Zurich without fatigue. Switch to Sport or RS and the steering firms up, the chassis tightens, and the 856 hp comes on with controlled progression — nothing abrupt, but clearly physical. The AWD setup guarantees maximum traction in all conditions. The artificial sound in Sport mode is subtle but present — the one slightly artificial element of the experience.
Daily charging
800V architecture with a 320 kW DC maximum — the highest in the Audi range. On a 350 kW Ionity HPC (E40 Loncin, E411 Daussoulx, E42 Verlaine), the RS e-tron GT peaks at 320 kW, meaning 10 to 80% in about 15 minutes. In 10 minutes you recover roughly 130 km of real range. On an 11 kW home wallbox, a full charge of the 105 kWh battery takes about 10 hours. The charging curve is one of the flattest on the market — power holds up well to 75–80% state of charge.
Total cost of ownership
€165,000: the highest entry price in Audi's EV range. For a Belgian company, the 100% deductibility in 2026 applies in full — a substantial tax advantage on this kind of sum. The benefit-in-kind (ATN) is calculated on the catalogue value, which means a non-trivial annual cost for the beneficiary. The direct comparison with the Porsche Taycan Turbo is fair: the two share the same platform and the same performance, with the Porsche priced slightly higher.
- 320 kW DC: the fastest charging in the Audi range — 10→80% in 15 min, 130 km recovered in 10 min on Ionity
- 856 hp in overboost, 0-100 in 2.8 s: supercar performance with the range and comfort of a grand tourer
- Porsche Taycan platform: benchmark electronic reliability and road behaviour in the segment
- 800V architecture: keeps charging performance stable from 5 to 80% state of charge
- €165,000: realistically within reach only via company leasing or structured financing for the vast majority of Belgian buyers
- 2,470 kg: very high tyre wear when driven hard — a set of tyres every 20,000–25,000 km in dynamic use
- 405-litre boot: not suited to regular family use
- High consumption in Sport mode: 28–35 kWh/100 km cuts range to ~300 km when driven dynamically
Our verdictThe RS e-tron GT is Audi's answer to the question: what does a versatile electric supercar look like? Its 320 kW charging, 856 hp and 455 km of real range make it, alongside the Porsche Taycan Turbo, the most complete electric grand tourer on the market. If your priority is pure performance combined with long-distance practicality, this is the top of the range. For 90% of use cases, the e-tron GT at €113,000 does the same job for €52,000 less.
A driving enthusiast with a substantial company budget, regular long European trips, drawn to performance and exclusivity. The 2026 Belgian tax case (100% deductibility) is especially favourable at this price point.
A family after a spacious SUV, a private buyer without a favourable tax structure, or a driver whose main use is urban or suburban.

Audi RS e-tron GT in Belgium — what you need to know
Typical Belgian trips
With 455 real km, the RS e-tron GT covers Brussels–Ardennes (≈ 260 km return) without charging, Brussels–Coast (≈ 220 km return) without charging.
Tax benefit
For self-employed and companies, this model is 100% tax-deductible in 2026 (last year at this rate). No direct purchase grant for individuals. Road tax is greatly reduced for this EV.
Home charging
With 11 kW AC, a full charge from 20% takes approximately 8 hours on an 11 kW wallbox. On a 230V plug (2.3 kW): about 37 hours. Overnight charging easily covers the average 50–80 km/day.
Frequently asked questions — Audi RS e-tron GT
What's the real-world range of the RS e-tron GT?
The RS e-tron GT is rated at 592 km WLTP. In real Belgian conditions — motorway at 120 km/h, moderately sporty driving — expect between 400 and 455 km. Driven hard (130+ km/h, Sport mode active), it drops to 320–360 km. In 10 minutes on a 350 kW Ionity charger you recover about 130 km of real range. The range is comparable to the standard e-tron GT — the RS difference is in available power, not in how far it goes.
How fast does the RS e-tron GT charge?
The RS e-tron GT accepts up to 320 kW on DC, the most capable 800V architecture in the Audi range. On a 350 kW Ionity charger (available on the E40, E411 and E42 in Belgium) it charges at 320 kW — meaning 10 to 80% in about 15 minutes. The charging curve is one of the steadiest on the market: power stays well above 250 kW up to ~75% state of charge. That's 5 minutes less than the e-tron GT (270 kW, 18 min) over the same cycle.
RS e-tron GT or Porsche Taycan Turbo: which should you choose?
Both share the same J1 platform, the same 105 kWh batteries, the same 800V architecture and very similar performance. The Taycan Turbo has slightly more power and a sportier suspension tune. The RS e-tron GT is generally 10 to 15% cheaper than the equivalent Taycan Turbo. On image, the Porsche remains the reference for pure enthusiasts. On performance-per-euro, the Audi is objectively better. The Porsche network is slightly more present in Belgium.
What's the difference between the e-tron GT and the RS e-tron GT?
The e-tron GT (€113,000) makes 476 kW (647 hp) on boost, does 0-100 in 3.4 s and charges at 270 kW DC. The RS e-tron GT (€165,000) makes 630 kW (856 hp) on boost, 0-100 in 2.8 s and charges at 320 kW DC (15 min vs 18 min). The real-world range difference is marginal (~5 km). The RS only justifies its €52,000 premium if maximum power and slightly faster charging are decisive criteria for you. For 90% of trips, the e-tron GT does exactly the same job.
Is the RS e-tron GT 100% tax-deductible for a Belgian company?
Yes. In 2026, all fully electric vehicles are 100% deductible for Belgian companies, with no price cap. On €165,000, the tax advantage is structural. The benefit-in-kind (ATN) for the beneficiary is calculated on the full catalogue value — which generates a non-trivial personal income tax. For company directors on a high salary, the net benefit depends on the marginal tax rate. Talk to your accountant to optimise the financing (operating lease, equity financing).
Is the RS e-tron GT suitable for everyday Belgian use?
In theory yes: 455 km real range, 320 kW charging, grand-touring comfort. In practice, a few things to consider: the 2,470 kg wears tyres very fast when driven hard (budget for an annual tyre bill), the 405 L boot is too small for four people's luggage, and consumption climbs to 28–35 kWh/100 km if you exploit the performance. For mixed daily use around Brussels plus long European trips, it's perfectly usable. It's not a car for the Saturday grocery run with two kids.
