If the name doesn’t immediately ring a bell, the cars he has designed certainly would – Ken Okuyama was responsible for the likes of the Ferrari Enzo, Ferrari P4/5, Maserati Quattroporte and more. Okuyama now runs his own design firm, and has introduced the Kode57 Enji to the Quail Motorsports Gathering which preceded the Pebble Beach Concours d’Elegance at the Monterey Car Week in California.

Given Okuyama’s chequered past with Ferrari, the 6.0 litre V12 engine that resides in the front of the Enji, which produces 611 hp and 607 Nm of torque, is most likely from the Ferrari 599 GTB Fiorano. The Ferrari connection doesn’t end there, surely.

Peering into the cabin, more 599 GTB cues are seen, with the previous-generation Ferrari steering wheel making an appearance, as does a lightly tweaked Ferrari instrument cluster which now resides in the centre of the dashboard, along with a selection of Ferrari switchgear.

A staggered wheel diameter setup of 21 inches in front and 22 inches at the back make up the rolling stock of the one-off concept car, while its carbon-fibre construction helps peg the car’s weight at 1,634 kg. That’s not all with the Ken Okuyama-designed concept; there’s even a tuning pack courtesy of Italian car specialists Novitec that will bring the 6.0 V12’s outputs to 692 hp and 641 Nm of torque.

Potent as the number are, the Enji is currently a one-off design concept, although Okuyama says he would love to have a small production run of the two-seater speedster.
