The predecessor types were fitted with narrow-V four-cylinder and four-cylinder boxer engine. These constructions were considered as too old and too expensive for the new model - hence unsuitable. Lancia was under time pressure. So, Lancia took a very sensible decision, by adapting the Fiat 124 engine to the new model Beta. This engine was fitted with two camshafts controled by a rubber toothbelt rather than a timing - chain and represented the highest technical state at the end of the Sixties. But the Lancia engineers were ambitious and didnīt transfer that engine without any modifications. Essential parts, like manifolds, camshafts and carburettors were revised. The result: more power and torque throughout the rev range . The maximum value of torque was now reached at 3000 rpm. In comparison the original construction by Fiat needed 4000 rpm. This character of torque is nowadays the thrill of driving a Beta. You donīt really need to change the gears so often.
