New car review: Mercedes-AMG GT 63 S 4MATIC 4-Door Coupe
Stunning performance comes with a high price.
No one really needs a $350,000 car with four-door practicality and Ferrari-rivalling performance.
But then no one really needs a sprawling five-bedroom, six-bathroom, multi-million-dollar mansion in Kangaroo Point.
These things are nice-to-haves for elites with the wherewithal to indulge their every desire. And if someone can afford a style-statement house like that, they can almost certainly afford a car like the Mercedes-AMG GT 63 S 4-Door.
These days it’s hard to find a category in Benz’s sprawling 20-model, 100-plus variant range that doesn’t have an AMG version.
Hence why no one should be surprised that the Affalterbach outfit were tasked with creating a rival for four-door sports coupes like the Porsche Panamera and BMW 8-Series Grand Coupe.
And when you have a drivetrain in the ultra-high-performance AMG GT coupe that leaves the outputs of these and other rivals in its dust, it’s possible to understand how the plan evolved to reboot the ballistic twin-turbocharged V8 in a more practical body style.
The GT 4-door’s monstrous 470kW/900Nm outputs and Porsche GT3 RS-rivalling pace (0-100km/h in 3.2 secs) are currently unrivalled in the Mercedes range, despite its price sitting several rungs below the S650L Maybach and a handful of S63 AMG models.
While its gaping grille mimics the AMG GT coupe and roadster, the GT 4-Door is a distinct model that’s loosely based on the E-Class, using the all-wheel drive system from the AMG E63 S.
It’s longer, wider, lower and more aggressive than the E-Class, with a coupe-like roofline that sweeps back over frameless doors to flared haunches, where a lift-back hatch reveals a useful 395-litre boot.
Rear seat accommodation is also surprisingly sensible with decent legroom and a comfortable seating position, although the plunging roofline, small windows, and dark headlining make it a tad sombre.
Up front, the driver grips a thick, suede-covered steering wheel, while nestled into body-hugging sports seats.
A tiny AMG gear selector sits atop the wide and high central console bisecting the cabin, with a bank of switches either side for features like the deployable rear wing and active exhaust system.
Other performance features include drift mode, rear wheel steering, and an active rear differential.
But the headline act remains the epic engine, which that idles so sweetly in traffic, yet attacks its 7000rpm redline with ravenous gusto when unleashed.
Despite its limousine-like abilities and substantial 2045kg kerb weight, the GT 4-Door changes direction with real dexterity, the steering impressively sharp and precise, the handling instantly responsive, the braking and grip levels insanely high.
Yet when wanting to cruise, the standard three-setting air suspension offers a wafting comfort mode, marking this as a surprisingly versatile, if eye-wateringly expensive, sports car cum grand tourer.
MLP: $349,900 (plus on-road costs)
