EC Only One (Italy) - AllCarIndex

E.C. OnlyOne was a boutique Italian marque created by former racing driver Enea Casoni in Ferrara. Its best-known car is the OnlyOne P8, presented in 2018: a road-legal, hand-built coupé on Ferrari F430 mechanicals (naturally aspirated 4.3-litre V8, six-speed manual), with gullwing doors and an emphasis on analogue driving; output was reported at about 600 hp. Period listings later offered the one-off for sale. Casoni also publicized the EC4 Metropolis in 2020, an analogue prototype featured in a maker video (with Valentino Balboni) claiming ~550 hp, manual gearbox and no ABS/traction control.
