Take a tour of the Mercedes-AMG GT63S and GT53 in photos

  • 1 / 22

    The Mercedes-AMG GT63S is the four-door version of the company’s beastly two-door¬†coupes.

    It gets a 4-litre (3,982cc for those bean counters) twin-turbo V8, and at $751,888 with COE, it’s meant to go up against the Porsche Panamera Turbo, which costs $721,688 (without COE).

    For outright power alone, the GT63S four-door handily beats the Panamera Turbo with 639hp and 900Nm to the Turbo’s 542hp and 770Nm.

    The four-door Mercedes-AMG is quicker too, hitting 100km/h in 3.2 seconds versus the Turbo’s 3.8 seconds.

    The Merc gets a wet-clutch AMG Speedshift MCT nine-speed transmission and has a top speed of 315km/h. Not that it matters in Singapore, but the Porsche Panamera Turbo can “only” hit 306km/h flat out.

    Mercedes is confident of beating pretty much every other four-door supercar: it claims the GT63S is the “fastest four-seater production car” to lap the Nordschleife, taking just 7 mins 25.41s.

    Mercedes calls the front of the GT63S a “shark nose” and we’re inclined to agree with them.

    It looks suitably aggressive and muscular with the Multibeam LED headlamps with carbon-fibre elements and AMG-specific radiator trim and front apron.

    The whole car is based on a hybrid construction principle that mixes steel, aluminium and carbon fibre.

    The bonnet and wings are made of aluminium, while the rear wall and boot cavity are made from carbon fibre.

    Steel, meanwhile, forms the ‘highly-rigid’ passenger cell.

    The long bonnet gets heavily contoured powerdomes that hint at the power lurking beneath, while the Airpanel radiator blind is position in front of the central radiator air inlet and improves the vehicle’s aerodynamic efficiency.

    V8 Biturbo badges on both wings mark out this particular variant of the four-door as the hottest one yet.

    However, rumours abound that an even-hotter version, the GT73 with 800hp, is set to break cover next year.

    From the rear three-quarters, the GT63S is suitably menacing, and we particularly dig those rear lights.

    All variants get frameless windows, as befits a four-door coupe.

    The tapered side line and broad shoulders, meanwhile, emphasise the vehicle’s sporting credentials and also leave interior space unnmolested.

    The broad rear falls in step with Mercedes-AMG’s other models, the GT and GT S.

    One interesting tidbit: while waiting at a red light, the brightness of the LED brake light is dimmed so the driver behind doesn’t get blinded.

    With the introduction of the Mercedes-AMG GT63S and GT53, the GT lineup now swells to six models.

    For reference, the GT, GT S, GT C Roadster and GT R are all still offered.

    The active rear spoiler is just one part of the GT63S’ active aerodynamics.

    It raises or lowers itself depending on the driving characteristics: it takes into account vehicle speed and lateral acceleration, as well as the position of the AMG Dynamic Select switch.

    The spoiler will deploy at speeds above 80km/h and can extend to its maximum of 182mm depending on the situation at hand.

    That maximum extension will only be activated at speeds of 120km/h and above when the car detects “highly dynamic” driving.

    The familiar 4-litre V8 found under the bonnet in multiple AMG models makes an appearance in the Mercedes-AMG GT63S.

    It’s now tuned for 639hp and 900Nm of torque, which is available from 2500-4500rpm.

    The GT63S can accelerate to 100km/h in just 3.2 seconds and tops out at 315km/h.

    The twin turbos are squeezed inside the Vee of the engine. That shortens the exhaust path and makes them more responsive as a result.

    But it’s not all fun and no clever work, to paraphrase: the engine also gets cylinder deactivation for better efficiency.

    In ‘Comfort’ mode, cylinders shut off from 1000-3250rpm to save fuel.

    To be exact, cylinders two, three, five and eight are deactivated, turning the engine into a four-cylinder while cruising.

    The GT63S also gets dynamic engine mounts for better handling.

    Every AMG product from Affalterbach follows the “one man, one engine” rule for absolute quality.

    Can you guess how many screens are there in the Mercedes-AMG GT63S?

    If you counted 13, you’re right. That number includes the two 12.3-inch Widescreen Cockpit displays, as well as the tiny little TFT LCD colour screens that make up the centre console and steering wheel buttons.

    They display the car’s current suspension, transmission and exhaust system setup, among other things.

    The AMG GT four-door range gets the sporty three-spoke AMG Performance steering wheel with a flat bottom and aluminium shift paddles.

    Seatbelts in the Mercedes-AMG GT63S are yellow.

    Aside from the standard three-seat, 40:20:40 split-fold rear bench, customers can spec a two-seater bench with electronics integrated into the console between the seats.

    The speedometer on the Mercedes-AMG GT63S goes all the way up to 360km/h. The question is: do you dare to?

    The GT63S gets composite discs front and rear as standard, clamped by six-pot callipers in front and a single-piston floating calliper at the rear.

    As an option, you can spec the bronze-colour AMG high-performance ceramic composition brake system.

    That improves brake fade under heavy braking and lightens the car’s unsprung weight.

    Boot space of 456 litres not enough? Fold down the rear bench to get 1324 litres.

    As an option, the tailgate can be opened and closed with the Handsfree Access feature which requires you to do some foot-jiggling underneath the rear bumper.

    As standard, the GT63S gets a lockable rear diff for maximum driftiness and a steerable rear axle for enhanced agility.

    Up to 100km/h, the rear wheels point in the opposite direction to the fronts, driven by two electric motors.

    That decreases the car’s effective turning circle and also improves turn-in.

    Above 100km/h, the system turns the rear wheels the same direction as the fronts.

    The active rear axle can be specced on the GT53 as well.

    No less impressive is the GT53, powered by a 3-litre, six-cylinder engine developing 435hp and 520Nm of torque.

    It gets the GT53 from 0-100km/h in 4.5 seconds and onto a top speed of 285km/h.

    It gets Mercedes’ 48V EQ Boost system that makes an additional 22hp and 250Nm of torque.

    It combines a starter motor and alternator in a single electric motor that’s integrated between the engine and the transmission.

    The EQ Boost system powers the lights, cockpit, infotainment and control units.
