BMW M3 CS Touring
This is officially the fastest production station wagon around the Nürburgring Nordschleife: it clocked 7:29.490 minutes.

Engine & specs: 3.0‑litre twin‑turbo inline‑6, about 543–551 hp and AWD (M xDrive). 0‑100 km/h in ~3.5 s. Top speed limited ~300 km/h.
What it means: you get “supercar‑like” performance with a practical wagon body — rare among modern estates.

Audi RS6 Avant GT (2024–2025 special edition)

Performance: 4.0 L twin‑turbo V8 producing about 621 hp, AWD, 0‑100 km/h in ≈ 3.6 s (≈ 3.3–3.4 s 0‑62 mph). Top speed (with optional extras) up to ~313 km/h (≈195 mph).

Estate usability: five‑door wagon body, cargo/cabin practicality + extreme speed — a hallmark “super‑estate.”

Why in 2025 list: It remains one of the very fastest and most balanced “performance wagons” you can buy today.

BMW M5 Touring (2025 plug‑in hybrid estate)
Powertrain: Combines a 4.4 L twin‑turbo V8 + electric motor (plug‑in hybrid), for a total output around 717 hp. AWD.

Performance: 0‑60 mph (≈0‑97 km/h) in ~3.1 s; quarter‑mile ~11.0 s at 129 mph. With optional package, top speed ~190 mph (≈306 km/h).

Usability: Despite being hyper‑fast, it remains a wagon with rear seats, cargo space — a serious “do‑it‑all” estate for those who want supercar performance + family‑car practicality.

Porsche Taycan GTS Sport Turismo (2025 electric estate)
Fully electric estate with supercar-level performance; in a recent “fastest‑estates” ranking it’s listed among the quickest estates globally.

According to data: 0–62 mph (≈0–100 km/h) as low as 2.4–3.3 s depending on version — making it not just fast, but possibly the fastest estate in straight‑line acceleration.

Why it counts: For those wanting electric power + estate practicality + near‑supercar performance, this is arguably the top “modern‑wagon” choice today.

🧠 How They Compare — Strengths & Trade‑Offs

Wagon / Model Strength / What It Offers Considerations / Trade‑offs

BMW M3 CS Touring
Record‑breaking estate track performance + usable everyday wagon
Very expensive, likely lower fuel efficiency, might be overkill for casual driving

Audi RS6 Avant GT
Massive power & speed, AWD, spacious / practical estate body
Heavy, thirsty engine, running costs (fuel / insurance) will be high

BMW M5 Touring
Hybrid performance + estate practicality — high power but some efficiency/hybrid benefits Very heavy, complexity (hybrid system), likely expensive maintenance

Porsche Taycan GTS Sport Turismo
EV — instant torque, supercar‑like acceleration + estate practicality & zero tailpipe emissions
Electric—range & charging constraints; high purchase price

🎯 Who’s Each Wagon Best For (in 2025 context)

Need max performance, but want estate practicality?
→ BMW M3 CS Touring or Audi RS6 Avant GT.

Want a “usable everyday super‑estate” (power + practicality + some efficiency)?
→ BMW M5 Touring.

Prefer modern electric drive + top acceleration + estate lifestyle?
→ Porsche Taycan GTS Sport Turismo.

Value flexibility — long trips, cargo, comfort, but with a touch of speed?
→ M5 Touring or RS6 Avant GT (or even slightly detuned variants).

🔎 Observations — What 2025 Tells Us About Wagons

The “estate” or “wagon/avant/touring” format is very much alive — and manufacturers still produce some of the fastest, most powerful cars in this body style.

Thanks to hybrid and electric powertrains (like in M5 Touring or Taycan Sport Turismo), you can now get performance + eco‑consciousness (compared to older pure‑gas super‑wagons).

For many buyers — especially those who want a mix of performance, utility, and versatility (family, cargo, road trips) — 2025 gives a surprisingly wide and exciting palette of choices.
