The Nissan GT-R – and its Skyline-based predecessors – has always been an unashamedly Japanese sports car, but for nameplate’s 50th anniversary Nissan has decided to look to Italy to mark the occasion. This is the GT-50 by Italdesign, a special concept version of the Godzilla developed and built by design house Italdesign, which coincidentally is also celebrating its golden jubilee this year.

That explains why the GT-R50 is covered by a smattering of gold accents all around, complementing the Liquid Kinetic Grey paint. The gilt finish covers the grille surround that appears as a separate element, stretching almost the entire width of the vehicle. This is paired with slim LED headlights, vertical front cooling intakes and a more pronounced bonnet power bulge, complete with vents also lined with gold.

Lowered by 54 mm, the sweeping roof features a double-bubble design with a deep central channel, which together with the taut, beefy rear haunches give the car added muscle. The GT-R’s “samurai sword” air vents aft of the front wheels have been lengthened and are again embellished with gold inlays.

The rear end is the most outlandish part of the car, carved out to look like a modular piece – a design emphasised by, you guessed it, yet more gold. The rear windscreen has been reduced to a single slit that stretches longer and deeper than the standard GT-R, and the trademark quad round tail lights have become hollowed-out pods that sit on the rear deck. A large adjustable rear wing completes the look.

Inside, the gold theme continues with accents across the futuristic race-inspired dashboard, finished with a black Alcantara wrap and carbon fibre trim pieces. The flat-bottomed steering wheel is also covered in Alcantara, with the central hub and spokes made from carbon fibre as well. The bucket seats, meanwhile, have been upholstered in black Italian leather.

Based on the GT-R Nismo, the GT-R50 has been fettled by Nissan’s motorsport division, with the 3.8 litre twin-turbo V6 now producing an estimated 720 PS at 7,100 rpm and 780 Nm of torque from 3,600 to 5,600 rpm. That’s a significant 120 PS and 128 Nm jump over the donor car.

The increases come by way of larger GT3-spec turbochargers, bigger intercoolers, redeveloped internals, higher-flow fuel injectors and optimised ignition, intake and exhaust systems. All this is routed through a strengthened, rear-mounted six-speed dual-clutch transmission to the GT-R’s magical ATTESA E-TS all-wheel drive system, equipped with reinforced differentials and driveshafts.

The chassis has also been tweaked through the addition of the Bilstein DampTronic I continuously adjustable damping system, connected to Brembo disc brakes with red six-piston front and four-piston rear callipers. The 21-inch alloy wheels, uniquely designed for this car, are wrapped in Michelin Pilot Super Sport tyres measuring 255/35 R21 at the front and 285/30 R21 at the rear.

“Although this is not the next-generation GT-R, it is an exciting celebration of two anniversaries in a provocative and creative way – wrapping one of Nissan’s best engineering platforms and Japanese design with Italian coachbuilding,” said Nissan’s senior vice president for global design Alfonso Albaisa.
