The Electric Supercar XING Mobility Redefines Raw Power

A while back, we wrote about a Taiwanese company called XING Mobility working on two prototypes. Today, the testing of the electric supercar XING Mobility is about to redefine raw power and thumb its nose at laggards.

The Electric Supercar XING MobilityA while back, we wrote about a Taiwanese company called XING Mobility working on two prototypes. Today, the testing of the electric supercar XING Mobility is about to redefine raw power and thumb its nose at laggards.

Sometimes the hyperbole never ends and sometimes it is justified. XING Mobility is starting to test its 1,341 hp rally-inspired electric supercar, the Miss R. And if spec numbers alone are anything to get excited about, racing is about to become a whole lot more spectacular.

The Electric Supercar XING Mobility

Hailed as the world’s first electric supercar with onroad and offroad capabilities, the “Miss R” is the company’s electric vehicle (EV) designed for serious performance driving. Harnessing a four-wheel torque vectoring system capable of launching it at roughly 168 MPH (270 km/h), 4 independent electric motors rated at 350V each will give the Miss R the edge over Tesla’s future Roadster 2.0 (base version). The 0–60 MPH will be covered in 1.8 seconds and the 0–124 MPH (200 km/h) in a blistering 5.1 seconds.

What makes the Electric Supercar XING Mobility Miss R different from other high-end performance EVs is that it is designed to reach that performance on almost any road surface. On-road, on-track, and off-road is the leitmotiv of the company that wants to offer a versatile driving experience no matter what the pavement.

According to XING Mobility’s Co-founder and CEO, Royce YC Hong: “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.” Indeed, XING Mobility is out to prove once and for all that the electric drivetrain is far superior to its contemporary internal combustion engine (ICE) cousin.

Although we won’t call it another Tesla killer — we have too many claimants that can’t deliver these days — the company wants to offer its powertrain to commercial and industrial vehicle manufacturers. Instead of just fighting on the personal transportation end of the spectrum or heavy duty and the public sector, XING Mobility is developing something that can be used by all. We’ve often hoped Tesla would open its drivetrain to other OEMs and converters. Perhaps this will entice the company to do so.

The idea of using a supercar as a proof of concept is not new. The trick is in finding the maximum performance battery cells can offer. The common 18650 lithium-ion cell format from most major battery suppliers can overheat and degrade. Maximizing power density while keeping thermal runaway under control is difficult. This is how XING Mobility plans to keep it under control.

Electric Supercar XING Mobility Miss R Keeps It Cool

The Electric Supercar XING MobilityXING Mobility finally disclosed the use of a patented immersion cooling technology called the XING Battery System. This system consists of stackable, LEGO-like battery modules which house 42 lithium-ion cells. They bathe in a special liquid from 3M called the  Novec™ 7200 Engineered Fluid. You’ve heard of overclocking a computer by dipping the motherboard in a cooled oil solution? That’s more or less it.

Essentially, the Novec Engineered Fluids is a family of non-conductive fluids used as solvent cleaning, for heat transfer applications, fire suppression, and supercomputer cooling. 3M calls it a smart, safe, and sustainable solution practical enough to find a use in keeping the battery cool.

The Electric Supercar XING Mobility is the first company to use the Novec fluids modularized its ingenious battery cooling system. The company says it helped it unlock the ability to achieve a continuous high-discharge power output, increased stability, and a high level of predictability with its heat transfer, non-flammable, and non-toxic properties.

The Electric Supercar XING MobilityAs to 3M, Michael Garceau, 3M Market Development for EV Battery Immersion Cooling, said: “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.”

Another added benefit of using Novec’s system is the ability to achieve this performance with fewer cells than in a normal situation. The Miss R’s battery pack can produce up to 1 MW of power using only 98 modules consisting of 4,116 cells. That is 30% to 50% fewer batteries than other electric supercars currently being produced. We can’t wait to see what Tesla and Rimac will have to say about that.

Where XING Mobility is also taking a different approach to range from other EV maker is that it will have swapping batteries. So far, the prototype can swap them in about 5 minutes.

Testing The XING Mobility Miss R

This will be followed by high-speed tests at full power. The complete prototype will be revealed late 2018.

So far, the company says it will build just 20 of the limited-production cars. They will be made available for purchase in 2019 with a price starting at $1 million.  Yes, now our favorite roadsters range from $200,000 to $1,000,000, Rimac Concept_One included.

The company says its XING Battery System’ will also work on city buses, ridesharing scooters, construction vehicles, and even sea vessels.

I don’t know about you, but this certainly spells the closing of an old combustion chapter. The electric drivetrain proves yet again that it’s here to stay and its performance makes gasoline-powered cars quaint.

You can follow XING Mobility on Twitter, Facebook, and Instagram.

So, XING, when can we try the Miss R? We can fly to Taiwan and test drive it if needed. 😉

Sadly, that is not Nicolas test driving the Miss R… at least, not yet!
