Pegaso Z-207
The Pegaso Z-207 was a truck model produced in Spain by Enasa from 1955 to 1959. It featured a V6 engine and a distinctive cab design. It was nicknamed Barajas, for the location, close to Madrid, where a new Pegaso plant was built to produce the Z-207. The Z-207 was advanced for its time; its 7.5 L V6 engine had an aluminum block with cast iron cylinder liners, balance shaft, and a direct fuel injection system. The engine had two interchangeable cylinder heads, one for each group of three cylinders. It produced initially 110 and later 120 horsepower , enough for the vehicle to reach a top speed of 90 km/h with its maximum weight of 11,320 kg. The engine was mated to a three-speed gearbox divided by a splitter-type system into three low and three high, combined with a two-speed rear axle producing a total of twelve speeds. The splitter control was mechanical, by means of a lever situated under the steering column. Another characteristic of the Z-207 was the independent front suspension with two superimposed trapezoids with helicoidal springs, each with a corresponding shock absorber offering a greater degree of comfort than a  typical industrial vehicle of the era. The "Barajas" range also included the Z-702, an articulated truck tractor for semi-trailers suitable for a payload of ten tons, and the Z-407, a rear-engined coach that never went into mass production. There was also a four-wheel-drive prototype, coded Z-213. The Z-207 was expensive to build and to maintain, and was gradually replaced by the more conventional but better-selling Pegaso Comet, which included some Leyland components. Total production of the Z-207 range was 5,737 units.
