XING Mobility announces rally-inspired supercar
Taipei-based electric powertrain startup XING Mobility announced a 1341-hp rally-inspired supercar. Miss R is described by the company as a vehicle designed for performance driving, utilizing four-wheel torque vectoring and capable of high speeds. Powered by four independent 350-V motors, XING’s prototype supercar has a projected performance of 0-100 km/h (0-62 mph) in 1.8 s, 0-200 km/h (0-124 mph) in 5.1 s, and a maximum speed of more than 270 km/h (168 mph).
XING Mobility’s co-founder and CEO, Royce YC Hong, said, “Miss R is the embodiment of the paradigm shift of EVs surpassing traditional combustion-engine cars in both performance and capability. The core idea behind the prototype is to achieve game-changing performance levels and driving experiences that are otherwise impossible to achieve in a gasoline-powered vehicle.”
A challenge that electric vehicle makers face with achieving maximum performance is that battery cells, such as the commonly used 18650 lithium-ion cells produced by most major battery suppliers, are at risk to overheat when rapidly charged and discharged. Although vehicles can be equipped with powerful motors, effective and safe methods of maximizing power density of these drivetrains is difficult with the current cooling and enclosure options on the market.
Miss R uses a patented immersion cooling technology, created by XING, for the battery system which consists of stackable, LEGO-like battery modules that house 42 lithium-ion cells that sit directly in 3M Novec 7200 engineered fluid.
Novec engineered fluids are a family of non-conductive fluids used for solvent cleaning, heat transfer applications, fire suppression, and supercomputer cooling. XING Mobility claims to be the first company to officially announce the use of Novec fluids for modularized battery cooling in electric vehicles, which XING says has unlocked the ability to achieve continuous high-discharge power output, increased stability, and a high level of predictability due.
“The use of Novec engineered fluids to immersion cool EV batteries is a breakthrough application, addressing the critical performance needs of the market in a new and disruptive way. 3M is delighted to work with cutting-edge companies like XING Mobility to leverage the unique properties of Novec Engineered Fluids, in their innovative designs, to deliver such extraordinary performance gains to the industry,” said Michael Garceau, who leads 3M’s market development effort for EV battery immersion cooling.
Miss R has undergone a series of initial tests, including one with the full drive-train exposed, the footage of which the startup has released in a teaser video. The next step will be high-speed testing of the vehicle at full power, with a view of revealing the completed prototype in late 2018. The company will build just 20 of the limited-production cars, which it intends to make available for purchase in 2019 with a price starting at $1 million.
