Mercedes-AMG GT 63 4MATIC+ now a 2+2

The second iteration of the Mercedes-AMG GT Coupé is now on sale in New Zealand, the top model available to order for $349,900.

In its latest two-door configuration, it features enhanced dynamic ability (AWD, AWS) for an even better driving experience and added practicality.

Within the composite aluminium body structure is a coupe with expanded dimensions, permitting 2+2 seating for the first time. Passengers up to 1.5m tall will fit comfortably in the pair of rear seats.

The body structure, which also features magnesium and fibre composite materials, is both rigid and low weight. Not only is there additional seating but also a larger luggage compartment volume. This can be expanded by split-folding the rear seats. Access is via a powered tailgate operates under gesture control.

A long wheelbase, short overhangs and steeply raked screen set the styling scene. Beneath the aero optimised body is a fully-variable 4MATIC+ all-wheel drive system instead of the former rear-drive configuration. Torque shuffles front or rear, depending on conditions, optimising traction and stability.

The car continuously shifts from rear to all-wheel drive and back. This improves longitudinal dynamics, promoting optimum acceleration. An electronically controlled locking differential on the rear axle further improves dynamics by ensuring the best traction of the drive wheels and enhancing cornering speeds. There’s also rear-axle steering for more agile and stable driving behaviour. 

Instead of antiroll bars, the AMG GT uses active roll stabilisation (Active Ride Control). The suspension hydraulics also feed a front axle lift system that raises the suspension by 30 millimetres, resulting in extra clearance of 41 mm at the front bumper. Extensive active aerodynamic elements are fitted front and rear.

A two-part active air control system called Airpanel features vertical slats behind the lower air intake in the front apron. The  second part is sited behind the upper air intake with horizontal louvres. Usually all slats are closed, to reduce air resistance and direct air towards the underbody, where it further reduces front lift. As temperatures rise the slats open to allow cooling air to flow to the heat exchangers.

A new retractable rear spoiler integrates into the boot lid and can automatically assume five different angular positions to optimise driving stability or reduce air resistance. Hidden in the underbody in front of the engine, a carbon profile lowers by around 40 millimetres at 80km/h to create a Venturi effect. This sucks the car onto the road and reduces lift on the front axle, improving steering and directional stability.

A hand-assembled 4.0-litre biturbo V8 powers the AMG GT. In the GT 63 4MATIC+, it delivers 430kW and 800Nm while mean fuel use claim is 14.1L/100km. The stated 0 to 100km/h figure is 3.2sec while it evidently tops out at 315km/h.

The engine mates to an AMG Speedshift MCT 9G transmission with a wet start clutch instead of a torque converter. Slowing the show is a composite brake system, the discs made of cast steel and brake pots made of aluminium. 

There are six driving modes, comprising Slippery, Comfort, Sport, Sport +, Individual and Race. The AMG Dynamics system determines ESP, all-wheel drive and steering settings, along with suspension set-up. Track Pace software records relevant data for track use and training.

The cabin centrepiece is an 11.9-inch, portrait-shaped multimedia touchscreen for navigation and various control and comfort functions. MBUX infotainment offers extensive AMG-specific content in five display styles. The driver‘s head-up display projects relevant information in 3D.

Powered sports seats offer plenty of lateral support and are all-ways adjustable. They automatically provide extra support in Sport, Sport+ and Race driving programs. There’s also a massage programme. The AMG Performance steering wheel is a double-spoke design, heated, with a flattened bottom and finished in Nappa leather. Two AMG steering wheel buttons permit the driver to control certain functions with the minimum of distraction. Aluminium shift paddles permit manual gear changing.

Highlights of the standard equipment list include a Burmester surround sound system, smartphone integration and wireless charging, MBUX Navigation, ambient lighting and a fixed panoramic sunroof with a mechanical blind.

External features include flush-fitting door handles, 21-inch AMG forged alloys, and black-painted AMG brake calipers.

Several packages are available as cost options at launch including AMG Night Package ($9900), AMG Carbon Fibre Package ($12,900) and the AMG Performance Seat Package $2490). 

Moreover, there are six leather upholstery colours, 12 exterior paint finishes and six alloy wheel designs.
