The Ferrari 275 GTB/4 NART Spider occupies a singular position in postwar automotive history. Enzo Ferrari had no interest in producing an open derivative of the 275 GTB/4, so Luigi Chinetti Sr.—Ferrari's exclusive US importer and founder of the North American Racing Team—commissioned Scaglietti to build a barchetta-style spider conversion. The result was a run of exactly ten cars, all completed in 1967, each with ten individual chassis numbers assigned by Ferrari and Scaglietti. KK Scale captures this landmark road car as a 1:18 die-cast replica finished in Rosso Corsa.
A Quad-Cam V12 in an Open Body
The 275 GTB/4 was already the most sophisticated Ferrari road car of its era when the NART Spider conversion was undertaken. Its 3286 cc Colombo V12 features four overhead camshafts—the first such arrangement on a Ferrari production road car—delivering 300 hp at 8000 rpm with dry-sump lubrication. The drivetrain layout is equally advanced: a rear-mounted transaxle provides near-perfect weight distribution, a configuration rarely seen on a road car of 1966–67. Scaglietti's open bodywork retains the fastback proportions of the berlinetta while adding a manually operated soft top.
Ten Cars, One Man's Persistence
All ten NART Spiders were produced at Scaglietti's Modena facility in 1967, with ten individual chassis numbers assigned by Ferrari and Scaglietti. Chinetti's insistence proved prescient: demand immediately outstripped supply, and the cars rapidly acquired legendary status. Despite being road-registered machines, NART Spiders appeared in period competition almost immediately—chassis 10453 finished second in class at the 1967 12 Hours of Sebring, driven by Denise McCluggage and Pinkie Rollo. Luigi Chinetti Jr. also campaigned examples in SCCA events during 1967–1968, cementing the model's dual road-and-race identity.
KK Scale Die-Cast at 1:18
KK Scale produces this replica in die-cast metal at 1:18, the format that rewards closest inspection in a display cabinet. The Rosso Corsa livery reflects the factory finish in which several NART Spiders were originally delivered, making it the most historically appropriate colour choice for this subject. KK Scale's 1:18 range is targeted at collectors who prioritise exterior accuracy and finish quality in a durable all-metal construction.
Placing It in a Collection
The NART Spider pairs naturally with the closed 275 GTB/4 Berlinetta—the donor car from which it was derived—as well as earlier open V12 Ferraris such as the 250 GT California Spider. For collectors drawn to Luigi Chinetti's racing legacy, it sits alongside NART-liveried competition Ferraris from the same period. The Rosso Corsa finish also makes it an anchor piece in any survey of 1960s Ferrari road cars, where its rarity of just ten produced sets it apart from more widely manufactured contemporaries.
Frequently asked questions
How many real Ferrari 275 GTB/4 NART Spiders were built?
Ten, all completed in 1967 by Scaglietti in Modena on the specific commission of Luigi Chinetti Sr., Ferrari's US importer.
Did the NART Spider ever race?
Yes. Chassis 10453 finished second in class at the 1967 12 Hours of Sebring, driven by Denise McCluggage and Pinkie Rollo. Luigi Chinetti Jr. also raced examples in SCCA events during 1967–1968.
What material is the KK Scale model made from?
The KK Scale replica is constructed in die-cast metal.
Why is the NART Spider finished in Rosso Corsa?
Rosso Corsa was among the factory finishes in which several of the ten real NART Spiders were originally delivered, making it the most historically grounded colour choice for this subject.
