The GT4 was a groundbreaking model for Ferrari in several ways: it was the first production Ferrari to feature the mid-engined V8 layout that would become the bulk of the company's business in the succeeding decades, and was the first production Ferrari with Bertone designed bodywork. The styling featured angular lines entirely different from its curvaceous 2-seater brother, the Dino 246, and was controversial at the time. Some journalists compared it to the Bertone-designed Lancia Stratos and Lamborghini Urraco, also penned by Marcello Gandini. From the cockpit the driver sees only the road. Enzo Ferrari himself took a major role in its design, even having a mock-up made where he could sit in the car to test different steering, pedals and cockpit seating positioning. The 3.0 L (2927 cc) V8 was mounted transversally integrally joined with the 5-speed transaxle gearbox. The engine had an aluminium alloy block and heads, 16-valves and dual overhead camshafts driven by toothed belts; it produced 255 hp (190 kW) in the European version and 240 hp (179 kW) in the American. The induction system used four Weber 40 DCNF carburetors.
