On August 23, GAC announced that the Hyptec brand’s Quark Electric Drive 2.0 rolled off the assembly line. The new EV motor claims to have the world’s highest speed of up to 30,000 rpm.

It should be noted that the Hyptec brand was formally known as Aion Hyper and is the performance EV marque for GAC. It recently changed its English name in preparation for exports. The brand currently produces three high-end performance EVs: the SSR, HT, and GT.

The Quark Electric Drive 2.0 has a motor power density of 13 kW/kg and a motor efficiency of 98.5%. These attributes, together with the 30,000 rpm, are meant to be world-beating. It uses a special material amorphous soft magnet, which is known as “liquid metal” because it has a permeability of 20-100 times that of an ordinary silicon steel sheet, and the thickness is only a quarter of that of an A4 sheet of paper. This gives the motor an overall efficiency of close to room temperature superconductivity which plays a vital role in improving the motor’s parameters.

What that all means in practice is that the motor can add up to 50 km of range for an EV without having to increase the battery size, or in the case of an EREV, it can increase range by 150 km. It’s also the equivalent of giving an all-wheel-drive car the same range as an existing two-wheel-drive car. GAC claims that the technology has the potential to save 90 billion kWh of electricity per year.

The Quark Electric Drive 2.0 will soon be installed on Hyptec models. Earlier this month, the brand launched a new generation of smart digital chassis. It has a minimum turning radius of 3.4 meters, which is a 40% reduction in minimum turn radius. The chassis has the industry’s first fusion electronic differential lock, which means that two wheels can easily get out of trouble when suspended.
