Nissan and Italdesign Create the 710-HP Nissan GT-R50 - Gallery

Inside, however, the GT-R50 no longer appears as minimalist or handcrafted.

Parts-bin switchgear and conventional instrumentation replace the all-digital cluster and metal toggle switches.

An infotainment system protrudes from the dash while the corner air vents shed their elaborate, layered construction.

Nissan likely deemed it too expensive to homologate such custom parts.

The Nissan GT-R is still running strong, if a little long, in its 10-year-old body. But this slick gold-on-silver rendering is our closest peek at the next Godzilla, and, we hope, the future of Nissan design.

The GT-R50 by Italdesign is a one-off prototype built by the famous Italian design studio.

It has been 50 years since Giorgetto Giugiaro opened his Turin shop in 1968, and also a half-century since the GT-R first appeared as a ferocious version of the defunct Prince Motor Company's new Skyline.

It matters not that Italdesign has been sketching continuously since then, while Nissan GT-R production was on hiatus from 1974 to 1988.

Just look at what the two companies have done together now. This Japanese-Italian fusion borders on beautiful—no easy accomplishment for the brutish GT-R.

Yet despite Italdesign's history of gorgeous concepts, the exterior and interior design credits go to Nissan's European and American studios. The GT-R50 is a street-ready version of the 2020 Vision Gran Turismo, a video-game car created by the same Nissan team in London.

Underneath, the GT-R50 is based on a real 2018 GT-R NISMO. The steeply sloped roof, lowered by 2.1 inches, melts into rakish C-pillars surrounding a V-shaped rear window.

The effect, combined with protruding round taillights and a rear wing that juts out from chiseled quarter-panels, is that of a mid-engined Ferrari.

Much of this newfound grace comes from stretching the body 3.7 inches and widening it another 3.8 inches. From behind, sharp vertical and horizontal creases blend into a large contoured fascia with small exhaust tips set within a simple venturi splitter.

Riding on 21-inch wheels, the GT-R50 retains just enough of the regular GT-R's stocky styling cues while trimming its visual bulk.

Up front, Nissan's chromed, V-mouthed grille is gone. The flat hood takes a steep dip to a wide, octagonal opening flanked by thin headlights.

The entire car manages to be square and smooth all at once, with neither aspect overpowering the other.

Fittingly, Nissan has not neglected the engine room. The twin-turbo 3.8-liter V-6 now makes a Hellcat-worthy 710 horsepower and 585 lb-ft of torque, a massive leap from the GT-R NISMO's 600 ponies and 481 lb-ft. Larger turbochargers, lifted from the GT-R GT3 race car, work with bigger intercoolers and high-flow fuel injectors and oil jets.

The crankshaft, pistons, connecting rods, bearings, and camshafts wear new part numbers, while the differentials, driveshafts, and six-speed dual-clutch transmission have been beefed up.
