Cars
During the 1960s, the cars developed from stock road cars into specially built cars with fabricated chassis and race-tuned V8 engines. While NASCAR also races specially-built race cars, they retain the appearance of a road car, unlike the BriSCA F1 which now bears no resemblance to a road car.
A modern BriSCA F1 is a race car with front engine, rear-wheel drive, and open-wheeled with the driver located centrally. Cars make use of an aerofoil mounted on top of the roof that is similar to those found on American Sprint cars. A BriSCA F1 Stock Car is constructed of a race engineering steel chassis with aluminium sheet body panelling and aerofoils (wings) with a robust roll-over/safety cage. They must weigh 1350–1500 kg and use a heavily modified Ford Transit rear axle with a 'Doug Nash' style gearbox with two forward gears (one for racing) and one reverse. The most common engine used, due to its reliability and availability, are race-tuned American Chevrolet V8 engine in both small block (350 ci) 5.7 L and big block (454 ci) 7.4 L varieties, producing upwards of 740 bhp with approx 640 ft·lbs of torque. There is no limit in engine capacity or number of cylinders but engines must be naturally aspirated (no fuel injection, no supercharging or turbocharging permitted). Cars can reach speeds of 80–90 mph around a quarter-mile oval so they use large roof aerofoils to create downforce on the corners to provide some extra cornering grip.
Many drivers use two separate cars; one will be set up primarily for use on shale or dirt ovals, while the other car will be set up for tarmac or asphalt ovals; however a few drivers with limited budgets may optimise just one car for both surface types, changing various components for each different track and surface.
