Marco Gramenzi and his Alfa Romeo 4C called “MG-AR 01 Furore” compete in Italian hillclimb. We first shared the race car in 2017 after it had swapped from a turbocharged 1.7 L inline-four to a naturally aspirated 3.0 L Zytek V8. At that time the V8 was producing 450 horsepower. HillClimb Monsters reports the car is now powered by a 4.0 L Judd V8 producing 670 hp at 10,500 rpm. Listen to the engine scream as Marco races in the E2-SH Class at Gubbio, Italy in 2023.
