Pegaso was an established company noted for its trucks and motor coaches, but also produced sports cars for seven years. Pegaso chief technical manager by then was Wifredo Ricart, former designer of the Alfa Romeo 512, and fellow rival of Enzo Ferrari, who at the time had also worked for Alfa Romeo. [edit]Design

The Z-102 employed racing-car technology in its chassis and alloy body. Everything was produced in-house at Barcelona, where the Pegaso cars factory was, with the exception of the external coachworking, either by Carrozzeria Touring, Serra or Saoutchik (although early Z-102 units carry Pegaso-made bodies). A four-cam all-alloy V8 engine, dry-sump lubrication, and a 5-speed non-syncronmesh gearbox mounted with the differential as a unit were within a pressed steel chassis.

The Z-102 started life as two prototypes in 1951 as a coupe and a drophead. The coupe and convertible had dumpy steel bodies, and weight was an issue to the extent that Pegaso made the decision to revert to alloy for the coachwork. Coachbuilder Touring then 'beautified' the design, replacing the grille with a two-piece cross, lowering the car, repositioning the foglights, and simplifying various details to give it a clean profile, similar to the contemporary Aston Martin DB2 and the Lancia Aurelia, that was the most memorable and numerous of all Z-102 bodies. The Z102 entered production with a 2.5 (2472cc) litre engine as used in the prototypes, though later there were variants with 2.8 (2816cc), and 3.2 (3178cc) litre DOHC desmodromic 32-valve V8 360 hp (270 kW) engines with multiple carburetors or optional supercharger. Horsepower ranged from 175 to 360, and, transferred through a five-speed gearbox and gear-driven camshaft, the fastest could reach 160 mph, (256 km/h), exceeding Ferrari autos, thus making it the world's fastest production car at the time.[citation needed] The base car had an 120 mph (192 km/h) top speed.

The main beams of the car's frame had large lightening holes, and the wheel wells under the body were used as stressed members. This rear-wheel-drive car had its transmission in the rear, connected to the differential (making it a transaxle). But it was unusually located behind the differential within a reverse A-frame whose apex was at the rear of the chassis. A fuel tank was situated on each side of the transmission. The rear suspension was of the De Dion type, with the unusual feature that, to restrain the tube from side-to-side movement, its tube had a small wheel at its midpoint that rolled in a vertical channel on the front of the differential (which in a De Dion system is bolted to the chassis) instead of using a Watts linkage or a Panhard rod.

However, the cars were heavy and brutish to drive and competition success was virtually nonexistent. Because the cars were built on a cost-no-object basis, this caused financial difficulty in the company. A simplified and cheaper version, the Z-103 with 3.9, 4.5 and 4.7 litre engines, was put into production, but to no avail, and the Z-102 was discontinued after 1958. Just 86 cars were produced, and out of these, only a handful of cabriolets were built. [edit]Racing and elegance contests

The Pegasos raced in several competitions, but with no real success. In the 1953 Le Mans trials, driver Jose Jover was seriously injured after crashing at more than 200 km/h. They competed also in the 1954 Carrera Panamericana, driven by Joaquin Palacio, with increasingly promising results in the first stages, but again an accident prevented an excellent final position. Furthermore, in September 25, 1953, in Jabbeke (Belgium), a Z-102 Touring BS/2.8 (the old Barchetta used at Le Mans, 2.8 litre single supercharger), driven by Celso Fernández, broke four official R.A.C.B. (Royal Automobile Club de Belgique) worldwide records (fastest of them, 243.079 Km/h (= 151.042 mph) average in the flying-start kilometer), previously owned by a Jaguar XK120. The original Z-102 BSS/2.5 Bisiluro Especial Competición (2.5 litre twin supercharged) meant to take on the records couldn't be used because of a blown engine.

Pegasos achieved much better results in several Concours d'Elegance contests. A Pegaso Z-102 coupé by Saoutchick, owned by Baron Thyssen-Bornemisza, was in this respect the epitome of coachwork sophistication, as it had seats upholstered with leopard skin and controls in gold, and in such a finish it won the 1953 Enghien-les-Bains (France) Grand Prix d'Elegance.
