Bizzarrini
5300 GT Strada

Why it matters

The 5300 GT Strada is the road version of Giotto Bizzarrini's own Grifo A3/C. It combines a Chevrolet Corvette V8, a fabricated platform chassis and a riveted semi-monocoque body, and it was built in very small numbers by an engineer more interested in racing than in series production. The A3/C-derived Bizzarrini-built Grifos won the GT class at Le Mans in 1964 and 1965.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Bizzarrini, who had developed the Ferrari 250 GTO and the Lamborghini V12, built the platform chassis for the Iso Rivolta GT and the shorter Grifo for Renzo Rivolta. At the 1963 Turin Motor Show two Giugiaro-designed Grifo variants appeared: the A3/L on the Bertone stand and the A3/C, built by Bizzarrini's own consultancy in Livorno, on Iso's stand.

Bizzarrini built the A3/C under agreement with Iso for about 18 months. When the two men fell out over racing versus production, a deal in 1965 let Iso use the Grifo name while Bizzarrini continued under his own name as the 5300 GT, in Strada road form and Corsa racing form. Production ended in 1969. A lack of a reliable body supplier and Bizzarrini's disinterest in series production are among the reasons given for the low output.

Identification guide

How to tell an original from a replica or later conversion.

RM Sotheby's describes early cars, such as chassis B0232, as sharing A3/C details: four taillights, deeper vertical vents, slim door handles, a more sporting dash and no bumpers, with a weight reportedly close to 200 kg below later cars. A 1967 alloy car has triple-vane wing vents. Gooding notes that the Strada's body was not built by Bertone and that the rear suspension is De Dion, not fully independent, so descriptions that say otherwise are wrong. Roughly 86 Stradas have aluminium coachwork, according to Gooding and RM Sotheby's.
