The development of the Lamborghini Countach was initiated by Ferruccio Lamborghini with the goal of creating a successor to the Lamborghini Miura.The Countach was designed around the existing Lamborghini V12 engine in a rear mid-engine, rear-wheel-drive layout. Named to honour the company's twenty-fifth anniversary in 1988, the 25th Anniversary Countach, although mechanically very similar to the 5000QV, sported considerable restyling done by Horacio Pagani. Notably, enlargement and extension of the rear 'air-box' intake-ducts was among other refinements undertaken.
