There is a new king of electric cars.

Mercedes-Benz’s Concept AMG GT XX prototype has demolished no less than 25 world records.

Mercedes-Benz said the prototype electric car concept “obliterated” the 24 hour driving record by more than 1500km after travelling 5479km in a single day.

It didn’t stop there, but kept the good times rolling for seven days, 13 hours, 24 minutes and 07 seconds to travel the equivalent of the earth’s circumference at the equator or 40,075km

It effectively travelled around the world in less than eight days and demolished the 25 records at various markers along the way.

The Concept AMG GT XX averaged about 5300km a day with an average speed of 300km/h.

Drivers had to stop to recharge the car, which Mercedes-Benz said achieved max charging speeds of about 850kW.

That’s an astonishing charging speed that puts it amongst the fastest charging cars on the planet. Only BYD has speedy replenishing EVs that can absorb about 1000kW or 1MW.

Currently the fastest charging vehicles on sale in Australia can take on 350kW of juice, but chargers capable of delivering that speed are far and few between. 

The record breaking test wasn’t completed on public roads, but at the high speed test track in Nardo, Italy.

Nardo’s test track is a high speed ring at about 12km long and has been a regular spot for ultra-fast speed tests for carmakers.

Mercedes-Benz used a team of 17 drivers — including its Formula One driver George Russell — to achieve the multiple world record setting test.

The test acted as a torture test to Merc’s new 'AMG.EA' EV platform, pushing the motors and charging infrastructure to the limit repeatedly for almost eight days.

The Mercedes-Benz Concept AMG GT XX gives a preview of the brand’s new flagship performance model and will be the most powerful AMG yet.

This puts it on a collision course with new Chinese rivals such as the Denza Z9 and Xiaomi SU7.

It uses three electric motors — which are coolly called axial-flux motors — to make a whopping 1000kW-plus. Mercedes claims these motors are about three times as powerful as conventional electric motors.

Its 114kWh battery can accept up to 850kW of charge. The battery chemistry is NCMA (Nickel-Cobalt-Manganese-Aluminium), which is an evolution of the high-capacity NMC batteries found in many long-legged EVs.
