Here’s Nissan’s GT-R50 concept car at Spa. That sentence should make sense to most of you, but if not, a little context.

First off, the Nissan GT-R isn’t exactly underpowered. It doesn’t suffer from a deficit of horsepower nor torque, and yet this has prevented precisely zero humans from modifying the iconic Japanese sports coupe.

Nissan itself had a go last month, turning out the spectacular concept car: a collaboration between itself and Italdesign celebrating 50 years of both the GT-R name, and Italdesign’s.

The GT-R50 pumps out 711bhp via competition-spec turbos, bigger intercoolers, a heavy-duty crank, stronger pistons, rods and bearings, a new exhaust and better cooling and oil systems. All good, solid engineering.

More so, the 3.8-litre twin-turbo V6 also managed 575lb ft. There’s no word on speed figures but we suspect it’ll start with ‘very’.

Nissan even announced that, should the humans of this world deem the GT-R50 interesting enough for purchase, it would build up to 50, worldwide, tailored to each individual buyer and with a starting price of somewhere around €900k (RM4.2m).

Now for the Spa bit. It’s one of the world’s best circuits, is really quite scary in places, tricky, and fast. Ahead of the Spa 24hrs, Nissan took out the one-off concept for a run.

And you must listen to it. So, here’s Nissan’s GT-R50 concept car at Spa.
