The XFINITY Series car flexes its muscle

January 05, 2015,

The NASCAR XFINITY Series car has an extra dose of muscle-car cool.

The current-generation XFINITY car -- which made its race debut in July 2010, just months before its first full season of competition -- features a different look with the "pony car" body style. The Ford Mustang and a sportier version of the Toyota Camry compete with the Chevrolet Camaro.

The design, which came after three years of research and development, features some interchangeable parts with Sprint Cup cars as a cost-saving measure. The car also made a change to a wider, taller body on a longer wheelbase -- all to help move the driver to a safer position near the center of the vehicle.
