Xing Miss R - On and Offroad Supercar
The Xing Mobility Miss R is a 1,000 kW (1,341 hp) all-electric supercar engineered to perform at full capacity both on and off road. Built by Taiwanese startup Xing Mobility, the Miss R uses four 350V electric motors, magneto-rheological suspension, and a proprietary modular battery system cooled by 3M Novec immersion fluid. It accelerates from 0-100 km/h in 1.8 seconds and reaches 200 km/h in 5.1 seconds.
A Modular Battery System Built to Be Swapped in Five Minutes
The most technically significant part of the Miss R is not its power output but how its energy storage is designed. Xing developed Lego-like stackable battery modules, each containing 42 lithium-ion cells. The Miss R carries 98 of these modules for a total of 4,116 cells. All cells are submerged in 3M Novec 7200 engineered fluid, a dielectric coolant that is non-conductive, excellent at heat transfer, and fire-suppressing. A depleted pack can be swapped for a fully charged one in under five minutes, a critical feature for a vehicle intended as much for R&D validation as circuit performance.
On and Off Road: The Miss R's Dual-Purpose Design
The bodywork of the Miss R is deliberately open in structure, with externally located wheels and wide open panels that allow the suspension to articulate fully in off-road conditions without the bodywork limiting wheel travel. The chassis is a composite construction, and magneto-rheological dampers give the suspension system a wide range of adjustment for road and trail conditions. Xing tested the car at an undisclosed location to collect data on performance, handling, suspension response, and long-term durability. This testing data feeds directly into Xing's wider ambition: the same modular battery technology will appear in a 3.5-ton truck, and the company is developing applications for boats, construction equipment, public transport, and ride-sharing platforms.
Torque Vectoring and Powertrain Layout
Four individual 350V motors, one per wheel, give the Miss R full torque-vectoring capability. That setup allows each wheel to receive a different amount of power depending on surface conditions, which is fundamental to why the car can transition between tarmac and loose terrain without losing control. The total peak output of 1,000 kW (approximately 1,341 hp) is available across both axles simultaneously. Detailed technical analysis of the Miss R powertrain and battery architecture is available from E-Mobility Engineering. New Atlas covered the Miss R at its initial reveal, with full powertrain and design details.
