A sports car does not require a large, powerful engine, though many do have them. Some classic British sports cars lacked powerful engines, but were known for exceptional handling due to light weight, a well-engineered, balanced chassis, and modern suspension. On tight, twisting roads, such an automobile performs more effectively than a heavier, more powerful luxury car with less maneuverability.
Due to North American safety regulations, many sports cars are unavailable for sale or use in the United States and Canada. In the United Kingdom, Europe, and the Middle Eastern market (e.g. UAE), a flexible attitude towards small-volume specialist manufacturers has allowed companies such as TVR, Noble, and Pagani to succeed.
