SU7: Hype vs Reality

This overview examines the gap between Xiaomi's marketing claims and the real-world performance of the SU7 electric sedan. While advertised with supercar specs—including 690 CV peak power, a 0–100 km/h acceleration of 2.78 seconds, and a theoretical CLTC range of 800 km—practical usage reveals key limitations. Real-world highway driving yields a range closer to 550 km (a 25–30% drop), along with physical ergonomic drawbacks like a slow-cooling onboard fridge and a fixed glass roof lacking an electric sunshade. However, long-term testing confirms that the core battery architecture remains remarkably durable, retaining 94.5% efficiency after 260,000 km.
