We’ve seen all sorts of obscure supercars with General Motors LS V8 engines over the years, but the new Giocattolo Marcella takes things to a new level – combining two 7.0L LS7 V8 engines together to create a massive 14L W16 engine good for roughly 1,400 horsepower.
Many North American readers probably haven’t heard of Giocattolo, but our friends down in Australia and New Zealand may be familiar with this rather infamous manufacturer. Giocattolo was founded in the mid-1980s by Australian entrepreneur Paul Halstead. According to CarAdvice.com.au, Halstead made a fortune in the computer business in the 1980s before he “blew it” developing the Giocattolo Group B – a modified Alfa Romeo Sprint with bespoke suspension and a mid-mounted V8 engine. Just fifteen Giacattolo Group B cars were constructed before the company went belly up, forcing Halstead to sell his family home to avoid going bankrupt.
Halstead told his then-wife Marcella that he would bounce back from the hardship and one day have enough money to produce a new supercar that he’d name after her. Halstead went on to found a major recruitment firm and now, at age 74, is ready to once again re-enter the difficult world of low-volume supercar manufacturing with this wild roofless two-seater that he refers to as a “Hyperod.” The heart of the Giocattolo Marcella is the 14L W16 powerplant, which was made by sticking two LS7 V8s 250mm apart at a 45-degree angle. While this arrangement may seem a bit absurd (especially given the fact that it displaces a ridiculous 14L) this arrangement allows the Marcella to easily produce 1,400 horsepower with full emissions compliance.
Making all this possible is a custom billet alloy bridge that runs between the two engines, which was designed engineered by Albins, along with a custom Albins transfer case and six-speed sequential gearbox. The suspension was designed and engineered by ex-McLaren engineer Barry Lock.
Halstead calls the LS7 powered Marcella a “Hyperod” due to its exterior styling, which takes inspiration from classic American cars as well as modern supercars and hypercars. The rear end, for example, features two dramatic tailfins that were inspired by a 1959 Cadillac.
Halstead hopes to show the finished Giacattolo Marcella at the Pebble Beach Concours d’Elegance in July 2022. Until then, he’ll be busy trying to make this ambitious idea for a custom supercar a reality.
