as an even distance between firing pulses per cylinder bank. Thus the engine was as smoothly running as a conventional 60-degree V6, but had greatly enhanced potential for the design of harmonically balanced exhaust manifolds, giving much better performance. Although the Dino V6 was discontinued with the introduction of the V8, the 65° design continues to this day: It reappeared on Ferrari's 1992 456 V12. The engine used in the 246 S produced with dual overhead camshafts pushing two valves per cylinder. The rear mid-engine, rear-wheel-drive layout 1961 Ferrari 246 SP used this same engine, as did the 246 P F1. A bigger displacement engine () with was used for the 1959 Dino 296 S. The 65° Dino V6 continued in racing after 1962, and made its way to the street as well. The 60° unit was no longer being developed after the SP-series. Ferrari needed to have the engine in 500 production vehicles to homologate it for racing use. The company worked with Fiat to develop a sports car to house it, and the front-engine, rear-wheel-drive layout Fiat Dino project was born. In competition, the 1965 Dino 166 P used a tiny version of the 65° unit. Both bore and stroke were different from the earlier engine at and output was impressive at . Bore was up to for the version found that same year in the Dino 206 SP as well as the 1966 Dino 206 S. In 1968, Ferrari debuted its own Dino 206 GT, the company's first mid-engined road car. It used the 2.0 L engine from the 206 S transversely-mounted between the rear wheels. In compared with racing 206 S version the engine of road 206 GT was detuned to . After producing just 152 cars, Ferrari bumped the bore and stroke up from to for . This increased power to at 7600 rpm and at 5500 rpm, but the engine block was now made of cast iron rather than aluminium. The same V6 engine was handed off to Lancia for use in its WRC-champ Stratos in the early 1970s, but Ferrari's Dino had moved on to 8 cylinders.
