A NEW 90 m.p.h. SPORTS FIAT.
IMPORTANT MODIFICATIONS TO THE SPORTS TOURER RESULT IN GREATLY ENHANCED PERFORMANCE FOR 1933.
LAST year the Fiat Company re-entered the sports car market with an extremely smart sports tourer on the 20-60 chassis. As a result of experience gained during the year, the engine and chassis have been modified for 1933, with a consequent increase in power and road-holding ability.
The basic design of the engine remains unaltered, and employs six cylinders of 72 ram. bore and 103 mm. stroke, giving a capacity of 2,516 c.c. Side-by-side valves are used with the sparking plugs accessible in the centre of the head. Ignition is by coil and the distributor is mounted vertically on top of the engine. Advance and retard is automatic, with a further movement controllable by hand.
The single vertical 35 rum. Solex carburettor has been replaced by two horizontal instruments of the same size bolted on to short pipes leading to the induction ports, a balance pipe joining the two. Petrol is drawn from a 12 gallon rear tank by an A.C. pump driven off the camshaft. The gearbox is mounted in unit with the engine, and power is transmitted by a single dry-plate clutch. The gearbox embodies a silent third gear, followed by a free-wheel, the first we can recall fitted
to a production sports car. The roller and inclined plane principle is used, a sleeve on the gearbox primary shaft which is provided with cams forcing the rollers into contact with a drum on the propellor shaft when not required. An open transmission shaft is used, fitted with metal universal joints at each end, and power is conveyed to the road
wheels through a spiral bevel back axle.
The Super-Sports Fiat is available with a short four-seater body by Viotti of Turin and has the graceful lines one associates with the continental sports car. The windscreen folds down and is fitted with dual wipers. For 1933 a pillarless saloon is also listed, overcoming the usual defect of difficulty of entry which is so often met with on sports saloons. We look forward to publishing a road-test
of this interesting car in the near future. The price of the sports tourer is £585, and the saloon sells at £645.
