Dubbed the type '33', the new Alfa Romeo was an altogether more ambitious machine as it was intended to run in the small displacement prototype class where Porsches reigned supreme. Very few existing parts could be used on this project so it took over two years before the first car was actually raced.In order to keep pace with the competition, Chiti's men designed Alfa Romeo's second ever mid-engined chassis. Unlike the TZ, which used a multi-tubular 'spaceframe' design, the 33 featured a simpler chassis built around three large diameter tubes constructed from riveted sheet aluminium. Two were used as side-members with the third connecting the two in the middle to create an 'H' shape. On both ends more conventional magnesium cross-members were also used to add further rigidity. The two side-members also housed the rubber fuel tanks.The 33's suspension was more conventional with double wishbones at the front and lower wishbones, top links and twin trailing-arms at the rear. Ventilated discs were used on all four corners, with the pair the back mounted in-board. A six-speed gearbox was also developed specifically for the 33.While the chassis was submitted to rigorous tests, the Autodelta engineers put the final touches on the all-new V8. Chiti had learned valuable lessons developing the ATS V8s, so much was expected from the new Alfa Romeo engine. Constructed from light alloys, it featured a twin-cam head with two valves and two spark plugs per cylinder. The earliest examples still sported Weber carburettors but by the time of its debut a more modern fuel-injection system was fitted. Despite its modest displacement of just 1995 cc, the high revving V8 produced a hefty 270 bhp at 9600 rpm. This was about the same as Porsche's similarly sized flat-8.Completed late in 1966, the first Alfa Romeo 33 was not shown to the media until March of the following year. The car sported a 'Spider' body with a periscopic engine intake that earned it the nick-name 'Periscopica'. The new car made a victorious debut at the Fleron hill climb in Belgium. Despite the long gestation period, the new 33 still proved fragile and failed to impress in international events that year. Additional victories were scored in hill climbs and also in a minor race at Vallelunga. Meanwhile development continued at Autodelta, focusing mostly on reliability and a more efficient body design. At Mugello a differently styled Spider was used but this remained a unique machine.
