The 2003 Sbarro Independent Wheel Drive is a groundbreaking concept showcased by Frank Sbarro, featuring a remarkable wheel design that integrates multiple automotive components into a single unit. This innovative wheel boasts a 22-inch seat diameter and contains a 160-horsepower engine, gearbox, cooling system, oil cooler, exhaust system, battery, suspension, brakes, and a small gas tank, all cleverly housed within its structure.
Sbarro highlighted the increasing size of wheels in modern vehicles, noting a 30-50% increase in space within them. He pointed out that as the diameter of wheels continues to grow, it allows for the installation of more effective braking systems. However, Sbarro's approach raises questions about increasing unsprung masses, as he boldly integrates essential components into the wheel itself.
The Independent Wheel Drive was demonstrated on various vehicles, including a single-track low-frame monotrace, a three-wheeled rear-wheel drive scooter, and a model of a four-seater hatchback. The latter application illustrated how this innovative design could extend the cabin length to an impressive three meters, showcasing the potential for increased passenger space and versatility in vehicle design. This concept reflects Sbarro's forward-thinking approach to automotive engineering, emphasizing the integration of technology and design to redefine traditional vehicle architecture.
