Giocattolo Marcella Is Hybrid of Hot Rod and Hypercar

The premiere of the car with a W16 engine will take place in 2022.

Australian Paul Halstead, known for his Giocattolo Group B with a five-liter Holden V8 installed behind the seats, has announced a new project called the Giocattolo Marcella. In the author's view, this is a cross between a hot rod and a hypercar: it doesn’t have a roof and doors, but the car is necessarily equipped with a W16 engine assembled from two Chevrolet V8s.

According to Halsted's plan, the new model will fall into the fictional hyperod segment and will rest on a carbon-fiber chassis. The car will have the same wheelbase as that of the Lamborghini Aventador (2,700 mm). External panels will be made of composite, in particular Kevlar. Resemblance to hot rods will be provided by an exposed engine, suspension components with push rods and horizontally mounted shock absorbers, as well as the pedal assembly, which will be visible through the low windshield. The Giocattolo Marcella will also have wide wheels (355/25 R21 tires will be installed at the back) and a minimum ground clearance.

Halsted's most famous work is the Giocattolo Group B with a modified Alfa Romeo Sprint body, a 5.0-liter 335-hp V8 developed for the Group A racing series, and a five-speed ZF transmission. This car accelerates to 100 km/h faster than the Ferrari 348 and reaches impressive 260 km/h. In total, 15 copies were built, but 13 of them were preserved.

The “core” of the Marcella and also the pride of Halsted is a W16 engine. It is assembled from two 45-degree angle-mounted 7.0-liter LS7 V8 Chevrolet supplemented by drive superchargers. The engine's crankshafts are connected to the center shaft via a custom-made distributor, and thrust is transmitted to the rear axle using a six-speed Albins ST6 racing sequencer and a high-friction differential.The unit will produce about 1,400 hp, but the safety margin of the transmission will be enough for all 2,000. The 1,250-pound hypercar will feature AP Racing brakes with six-piston calipers.

Despite the fact that the car has been built for a year and a half, the official premiere will have to wait a long time: a public debut of the Giocattolo Marcella will take place at the Pebble Beach Concours d'Elegance in July 2022. It is planned to assemble the model at a factory in the suburbs of Melbourne, as well as at a new enterprise that Halsted is going to open in the United States.
