Sleek NASCAR NEXTEL Cup Race Cars Designed for Speed and Power
from: Maxx Sports GuidesThey started out racing strictly as stock cars. Eventually, the cars were customized and modified for the driver's safety and to give him an edge over his competition.
Today, the vehicles are classed as NASCAR NEXTEL Cup Race cars. The customizing of the cars follows NASCAR rules defining a NASCAR NEXTEL Cup Race car.
Basically, NASCAR NEXTEL Cup race cars are modified American-built sedans. They're required to have only three standard stock parts: the hood, the roof and the trunk lid. All the other parts are left to the teams assembling the race car.
A NASCAR NEXTEL Cup race car weighs about 3,400 pounds, with a wheelbase of 110 inches. Fuel should have a 110 octane rating. Fuel tank capacity is about 22 gallons. Top speed is about 200 miles per hour.
Unlike carburetors found on most cars today, NASCAR NEXTEL Cup race cars use carburetors with an electronic fuel injection system. The race cars also have an eight-cylinder, 750-horsepower engine.
Templates are used to build NASCAR NEXTEL Cup race cars and minimize any variation in size. As a result, the cars look similar. They're designed with a sleek, aerodynamic shape.
Less air friction means higher racing speeds. Making the car aerodynamically efficient gives the driver an edge over other car shapes and keeps them ahead of the competition.
Accurate dimensions and fine tolerances are required to ensure that all engines and components fit properly as designed. This enables drivers to get the most power out of their engine.
Cylinder head ports are reshaped to remove inherent flaws from the factory and increase engine efficiency and horsepower. Cylinder head ports are critical as these allow air and fuel to travel through the engine's cylinders.
Finally, a NASCAR NEXTEL Cup race car wouldn't be complete without safety devices. These include seatbelts, roof flaps, window nets, a safe windshield made from a polycarbonate material, a fuel tank with a hard plastic inner layer. All these devices and more should be integrated into the race car's design and assembly.
Improvements and modifications are expected to continue as car owners and teams pursue their quest for speed and supremacy on the track.
These high-end, powerful NASCAR NEXTEL Cup race cars are certain to provide a treat for NASCAR fans in each race they see.
