L'Alfa Romeo<\/a> The 4C, 12 years after its launch, continues to arouse the passion of Alfisti. It's the Biscione's last production coup\u00e9 sports car to date. And if it didn't have the honor of an official GTA version, others did! It doesn't have the record of Pogea Racing's 4C Nemesis, which exceeded 400 hp, but the Horus SC73 is far from ridiculous! With a name like that of an Egyptian divinity, it's bound to go straight to the top.<\/p>\n\n\n\n

A transfigured engine<\/h2>\n\n\n\n

SC73 is the name of the tuner in question, Scara 73. To guarantee the best possible performance, the engine and gearbox mapping were specifically developed. Further modifications were made to the oversized intercooler, which keeps the temperatures generated by increased performance under control. The intercooler was developed with a motorsport radiator core, CNC lower plate and carbon upper plate, smooth on the inside for excellent fluid dynamics and unrivalled thermal efficiency.\u00a0<\/p>\n\n\n\n

The 1.7L turbo engine now delivers 335 hp and 515 Nm of torque, compared with 240 hp and 350 Nm for the original Alfa Romeo 4C. Performance? According to Scara73, the 0 to 100 km\/h time is 3.05 seconds, the 0 to 200 km\/h time 7.05 seconds, for a top speed of 306 km\/h. The raucous roar of the engine is enhanced by a 3-tailpipe titanium exhaust system, while the chassis is equipped with \u00f6hlins racing-style, bi-directional suspension with separate compression and rebound damping.<\/p>\n\n\n\n

An enormous slimming cure!<\/h2>\n\n\n\n

To achieve such a result, the greatest effort went into lightening the car, in the pure \"GTA\" (alleggerita) spirit of the Bertone GT coup\u00e9 of the 60s. Using autoclaved carbon fiber, the gains are impressive. The 17- and 18-inch forged wheels, in Quadrifoglio gold finish, reduce the weight from 39.6 kg to 27 kg. Carbon and alcantara bucket seats reduce seat weight from 18.3 kg to 5 kg. <\/p>\n\n\n\n

The magic of carbon reduces the weight of the doors from 46.2 kg to 17 kg. The end result? The 4C Horus weighs in at 769 kilos unladen, almost 200 kilos less than the base 4C, which in itself was very light for a modern car, being under a ton unladen! Horus promises to \"feel the difference in every bend\", and we'd like to believe it!<\/p>\n\n\n\n

Inside, carbon is also king, notably on the center console and even the steering wheel paddles, but the most notable visual change is the steering wheel. The original one isn't necessarily very popular with Alfists, who will find here a 3-spoke Racing-type steering wheel, with an on-axis wheel position indicator.
