I was watching a lucky fellow at the weekend, driving his Ferrari around town along some cobbled streets.
The tyres were making quite a noise as they fought for grip on the polished, uneven surface.
Today’s invention is for ultra high-performance vehicles (including dragsters and motorcycles).
Each wheel is fitted with a hub-mounted set of rocket motors. These are free to maintain their orientation as the wheel itself rotates.
When a burst of intense acceleration is demanded of the engine, so the rockets fire upwards briefly, forcing the tyres into very high-pressure contact with the road surface.
