A concept of mine: NIO ETX. The Performance Technology Flagship

A hypothetical NIO halo sedan inspired by the EP9’s performance DNA, but engineered as a road-usable GT sedan rather than a track-only hypercar.

Built on a next-gen NT4.0 architecture with a realistic focus on efficiency, software, and battery swapping compatibility.

Key Concept Specs:

• Platform: NT4.0 performance chassis (aluminium + composite hybrid structure)
• Voltage system: 925V architecture
• Powertrain: Quad-motor AWD with full torque vectoring
• Output: \~1,000–1,200 hp
• 0–100 km/h: \~2.0–2.3s
• Top speed: \~310 km/h

Battery & Efficiency:

• 150–180 kWh next-gen pack (semi-solid state direction)
• Battery swap compatible (NIO ecosystem core feature)
• Ultra-fast charging capability (\~5C peak, hardware dependent)
• Real-world range target: 650–850km (depending on setup)

Chassis & Dynamics:

• Active air suspension (track + comfort adaptive modes)
• Rear-wheel steering
• Predictive damping via road scanning
• Performance-oriented aero with active front/rear elements
• Designed for stability at high speed rather than pure hypercar extremity

Design direction:

Still unmistakably NIO: clean surfacing, minimal lines, but lower, wider, and more aggressive than ET7/ET9. No excessive sci-fi elements — more “executive GT fighter jet” than concept fantasy.

Positioning idea:

ET9 = luxury executive flagship

ETX = performance flagship (road-going EP9 philosophy, but usable daily GT sedan)
