STUTTGART: The Concept AMG GT XX recently broke a total of 25 long-distance records on the legendary high-speed test track in Nardò, Italy – a site where the world’s fastest cars have been put to the test for decades.
Among them was the record for the greatest distance ever covered by an electric vehicle within 24 hours.
The previous record was under 4,000 km (2,485 mi), which the Concept AMG GT XX has far surpassed.
The technology platform traveled 5,479 km (3,404 mi) in 24 hours – 1,518 km (943 mi) more or 38 percent further than the previous record.
But this was just one of many records that the Concept AMG GT XX secured with a commanding lead.
The technology pioneer’s extreme test lasted far longer than 24 hours.
The goal: to drive “around the world in eight days” – a mission to prove the superior long-distance performance of the AMG electric drivetrain.
The name of the challenge? A nod to Jules Verne’s “Around the World in 80 Days.”
The record run followed an exceptionally demanding schedule. The greatest strain on motors and battery occurs under high-load driving and high-speed charging cycles.
To simulate this scenario repeatedly, the Concept AMG GT XX was tasked with covering as long of a distance as possible in the shortest possible time.
Drivers maintained a constant speed of 300 kph (186 mph), stopping only to recharge at power levels averaging around 850 kW – far beyond what today’s charging infrastructure can provide.
After each charging stop, the vehicle accelerated back to 300 kph (186 mph) – over and over, day and night, for eight relentless days.
Featuring three axial-flux motors and a directly cooled high-performance battery, the concept vehicle promises a new dimension of power and endurance.
Mercedes-AMG has now proven this under extreme conditions – the ultimate test evoking the record runs of the past.
The test was not only a feat of technology, but also of teamwork.
From the pit crew handling charging and tire changes, to the round-the-clock provision of fire and rescue services to the remote support room in Affalterbach, which was permanently connected to Nardò via remote diagnostics.
External specialists – including tyre supplier Michelin and charging station specialist Alpitronic – rounded off the expert crew.
The revolutionary drive concept with three innovative axial flux motors and a high-performance battery developed from scratch enabled a new dimension of continuous electric power and ultra-fast charging.
The axial flux motors are considerably more compact and lighter but above all significantly more powerful than conventional electric motors.
The power density of axial flux motors is around three times higher.
This enables top-level driving performance that can be reproduced very frequently and repeatedly.
Three axial flux motors and a directly cooled battery concept
The Concept AMG GT XX generates a peak output of over 1,000 kW (over 1,341 hp).
The high-performance battery is a completely new development from Affalterbach, inspired by Formula 1.
The Concept AMG GT XX can charge extremely quickly - at over 850 kW across a wide range of the charging curve.
In just five minutes, it can recharge for a range of 400 km (WLTP).
