Miss R electric supercar’s international debut

Electric vehicle start-up Xing Mobility presented its rally-inspired supercar Miss R to business leaders and industry analysts at Goldman Sachs’ TechNet Conference in Hong Kong this week.

The 1mW supercar was displayed above its 4116-cell, 98-module battery pack to expose what the company considers “the core of their electric powertrain systems”.

The car’s international debut at the conference follows Xing’s release of Miss R’s first on-road/off-road test footage last month.

This week, the company also launched its collaboration with Taiwanese artist Tong Yang-Tze by displaying the car with a modern black-and-white Chinese calligraphy livery.

At full potential, the supercar’s four 350V motors and 1mWcbattery pack is projected to reach performance levels of 0-100km/h in 1.8 seconds and 0-200km/h in 5.1 seconds.

The detached battery pack display also reveals fast battery swap technology that sees the entire battery enclosure exchanged within five minutes.

Orders for the car are expected to start this year and a complete prototype unveil is set for 2019.

“A considerable number of cells are needed to power electric vehicles,” Xing Mobility chief executive officer Royce YC Hong says. “The R&D and financial investment needed to develop, connect and package these cells often far exceed the budgets of small-medium sized vehicle manufacturers. It has taken established electric car manufacturers like Tesla and Nissan years to perfect efficient but complex battery packs which are highly tailored towards their specific vehicle types, and there are very few readily-available and reliable options for commercial and industrial vehicles.”

The company is working with vehicle makers from around the world to apply the battery and powertrain technology from Miss R in city buses, ride-sharing scooters, construction equipment and special-purpose boats.

Xing’s immersion-cooling, modularised battery system works by directly submerging batteries in 3M Novec, an engineered cooling fluid vastly improving heat transfer and cell uniformity, and allowing for market-leading power density.

Co-founder and chief technical officer Azizi Tucker says the battery pack’s Lego-like design caters to the wide variety of shapes, sizes and power requirements within commercial fleets.
