Xiaomi's SU7 Ultra is set to receive a significant update in China, featuring a massive rear wing that promises to challenge the Porsche Taycan Turbo GT's lap record on the Nürburgring-Nordschleife. This development comes as the electric sports car aims to boost Xiaomi's brand reputation and sales performance, with a recent dip in sales figures. The update includes a wider rear wing for increased downforce, similar to the Porsche 911 GT3 RS, and carbon fiber side-view mirrors, LiDAR sensors, and large yellow brake calipers. The SU7 Ultra's performance specifications include a 0-100 km/h acceleration time of 2.1 seconds and a range of 630 km under CLTC conditions, powered by a 93.7 kWh battery pack and three electric motors generating up to 1,138 kW (1,526 hp). However, the SU7 Ultra faces competition from the Denza Z performance coupe, which boasts an even more powerful 1,180 kW (1,582 hp) and a maximum speed of 350 km/h, while being 140 kg lighter, potentially giving it an edge in cornering speeds. This development raises questions about the future of electric sports car competitions and the strategies of automotive brands in the rapidly evolving electric vehicle market.
