This trims straight-line performance, the new GT 53 accelerating from 0-62mph in a claimed 3.5sec compared with 2.4sec for its more powerful sibling. Top speed is electronically limited to 143mph as standard or 155mph with the optional AMG Driver's Package, whereas the GT 63 can be specified to reach a limited 186mph. The GT 53 utilises the same 800V electrical architecture and 106kWh liquid-cooled battery as the GT 63, but dropping one motor has boosted its official range from 424 miles to 503 miles. The GT 53 also shares the GT 63's air suspension with adaptive damping and torque vectoring. The GT 53 will form the new entry point to AMG's electric GT range ahead of additional models planned over the coming years.
