Mercedes-AMG GT Black Series revealed with 537kW V8

Mercedes-AMG has unleashed its GT Black Series with 537kW and 800Nm of track belting grunt.

The long-awaited Black Series version of Mercedes-AMG’s GT sports car packs the most powerful series-production V8 engine that AMG has yet made.

The GT Black Series’ twin-turbocharged 4.0-litre V8 puts out 537kW and 800Nm of torque. That’s 107kW and 100Nm more than the next-fastest variant, the GT R Pro. The Black Series’ V8 has been modified so extensively from the existing unit that it has been given its own engine code.

The new engine features a racing-spec flat-plane crankshaft, unlike the regular versions. Its altered cylinder firing order is said to improve throttle response and power output. A distinctive engine sound has been heard in an official video. New camshafts, bigger turbos mounted on anti-friction bearings, a beefier intercooler and an uprated exhaust system all reap the benefits of the new layout.

The result is a claimed 0-100km/h time of 3.2sec, 0-200km/h in 9.0sec and a top speed of 325km/h. Power is put through the rear wheels only via a seven-speed dual-clutch automatic gearbox, itself modified for better shift response and with altered ratios. It combines with a revised Race Start function, promising even more impressive launches.

The motorsport theme is apparent in the exterior appearance of the GT Black Series, which looks much like one of Mercedes’ GT3 or GT4 racing cars. At the front, a larger air intake combines with airflow-optimising ‘flics’, a two-stage manually adjustable carbonfibre splitter and a carbonfibre bonnet with downforce-boosting exhaust air openings and cooling slats.

Wider sill panels contain brake cooling ducts, while a large rear diffuser and two-piece spoiler feature along with adjustable aerofoil flaps, which can reduce air resistance or improve stability depending on the driving situation. Combined with an almost fully flat underbody, the aero measures give the car claimed downforce of 400kg at 250km/h.

Weight reduction comes courtesy of extensive use of carbonfibre. As well as the bonnet, roof and tailgate, details such as the transmission mount, new body stiffening structures and even the driveshaft are carbonfibre.

Lightweight forged wheels hide standard-fit ceramic brakes with Black Series-specific components. Even the front and rear glass is thinner. However, no weight figure has been quoted yet.

The GT Black Series follows the GT R in using adjustable coilover suspension combined with an adaptive damping system. Aluminium components reduce unsprung weight and solid rear wishbone bearings taken straight from AMG’s motorsport programme are said to improve steering sharpness and feedback.

Among the multiple driving mode settings (which also include a nine-mode traction control system) is a new function in Sport Plus that can detect the race track surface and set the car up accordingly. The camber is also manually adjustable, while AMG has worked with Michelin to develop a specific Pilot Sport Cup 2 tyre with soft and hard compound options.

Inside, the GT Black Series gains a unique interior spec that mixes leather and microfibre with black and orange stitching and matt black carbonfibre trim. Weight-saving door panels with loop pull handles also feature. Options include carbonfibre bucket seats and the AMG Track Package, which adds titanium rollover protection, four-point belts and a fire extinguisher.

Automotive Daily understands the GT Black Series will be priced at the equivalent of AUD$600,000 in Europe – more than three times the cost of the base GT and $150,000 more than the current range-topping GT R Pro. It will be available in Australia next year, with pricing to be announced closer to its arrival.
