Mercedes-Benz AMG GT vs Mercedes-AMG E63

What's the difference?

Once upon a time, people would dream about owning a Mercedes-Benz 450SLC – the C107 sports/luxury coupe flagship of the 1970s.

Sexy, stylish, secure and incredibly solid, it embodied the brand’s ‘Engineered Like No Other Car' mantra of the era.

Today’s all-new, second-generation, C192 AMG GT Coupe is something of an indirect descendant of this sort of thinking, changing tack from its supercar-esque 2014 C190 predecessor, with more space, more seats, more sensibility and, conversely, even more steak and sizzle from its glorious V8.

A modern-day SLC? The Porsche 911, Aston Martin DB12, Maserati GranTurismo and Bentley Continental GT’s worst nightmare? Or something else entirely?

These questions and more are answered below.

Feels like lately all the Mercedes-AMG buzz has been at the smaller end of the scale.

Most recently, the screaming GLA 45 S has arrived in Australia, pumping out more kilowatts and newton-metres than any compact SUV has a right to.

But here, we're doubling the cylinder count to eight, arranging them in a vee, and lighting the wick on AMG's powerhouse mid-size sedan, the recently upgraded E 63 S.

While the ferocious twin-turbo V8 and the rest of this beast's powertrain are unchanged, the car has been brought up to speed with some aero-focused styling tweaks, Merc's latest 'Widescreen' digital cockpit, as well as the MBUX multimedia system, and a tricky new multi-function sports steering wheel.
