FAB WHEELS DIGEST (F.W.D.): Bizzarrini 5300 SI Spyder (1967-68)

The 5300 SI Spyder was the prototype for an open top version of the Bizzarrini 5300 GT. The concept was one of the stars of the 1966 Geneva Motorshow. Under Bizzarrini's supervision, its all-alloy body was developed at Turin's Stile Italia (SI). Other unique features included retractable head lights, seats molded in the body and a multi function roof design. The alloy hardtop was fitted with separate roof panels, which allowed the Spyder to be a Coupe, Targa or full Convertible. Two more examples were produced in 1967 and 1968 by Stile Italia, both slightly different from the Geneva 'Prototipo'. The same collector also owns the other two 5300 Spyders.

The car was powered a 327ci (5.4L) Chevy small block V8 that was tweaked to produce 420hp. It featured an all aluminium alloy body with a tubular frame, which helped keep the weight to just 2535lbs. And was equipped with adjustable independent suspension, and magnesium, power assisted brakes, all cutting edge racing technology at the time. It offered truly astonishing performance for its day.

The concept prototype featured retractable head lights, seats molded in the body and a multi function roof design. The alloy hardtop was fitted with separate roof panels, which allowed the Spyder to be a Coupe, Targa or full Convertible.

When Bizzarini's company went out of business, the prototype went to his attorney, who stored it in an underground garage in Pisa, Italy. There it sat for 35 years until it was discovered, acquired, and restored by Plymouth, Michigan Bizzarini aficionado Mark Sassak. (conceptcarz.com)
