The fuel consumption rate of a V8 Supercar can vary depending on several factors, including the engine size, driving conditions, and the driver's technique. However, to provide a general estimate, a V8 Supercar typically consumes around 80 to 100 litres (approximately 21.1 to 26.4 gallons) of fuel per 100 kilometres (62.14 miles). This means that a V8 Supercar can cover approximately 1.25 to 1.5 kilometres (0.77 to 0.93 miles) for every litre of fuel consumed.
V8 Supercars are high-performance vehicles with potent engines that require substantial amounts of fuel to generate the necessary power. Moreover, they are often raced in circuits requiring rapid acceleration and deceleration, which further contributes to higher fuel consumption.
