The Houghton Mifflin definition of the two-seat rule seems out-of-date. Many sports cars today offer small back seats (sometimes referred to as 2+2 seating) and there is a current movement underway to increase the seating room in models long considered sports cars by most automotive experts.
Insurance companies use their formula in classifying automobiles and often the presence of two doors automatically makes any car a sports car in their eyes. This perspective, of course, is as overly simplistic as the standard dictionary approach to defining a sports car. One can certainly think of any number of two-door vehicles that fall far short of being an actual sports car. Economy cars and even larger two-door vehicles that are not built with power and performance in mind should not qualify as true sports cars.
Some car buffs will refer to high-performance muscle cars and other larger vehicles as sports cars. Others, however, distinguish these vehicles and true sports cars. These individuals will claim that a car can be a sporting car or simply sporty but still fall short of being a true sports car. Thus, regular cars may be outfitted with a sports package and/or accessories to make the car sportier, but may not fit a strict definition of a sports car.
Not all automotive enthusiasts, however, embrace this restrictive view of sports cars. In many circles, a sports car is any car offering greater performance or power than more standard offerings. This school of thought will consider muscle cars and other larger vehicles designed with performance in mind as sports cars.
Others will maintain that the distinction between a sports car and any other type of car lies in how the car’s suspension and handling are addressed. Technical debates rage over whether various suspension packages qualify as belonging to true sports cars.
Some will argue that a sports car can be defined by its intentions. If the car is designed for performance more so than for utility, they say, it is a sports car. This intent-based definition, however, provides little guidance in determining whether a car is a sports car or not. Particularly in the modern era, the notion of designing a car of any sort without significant consideration of its feasibility and utility seems unlikely. Any commercially viable vehicle, regardless of its performance, must retain significant utility.
Road and Track, a leading automotive publication, summarizes the sports card definition debate with a simple observation: Ask five people the exact definition of a sports car, and you’ll likely get five different answers.
There is no clear-cut definition of what is a sports car. The restrictive definitions of the past seem ill-suited to categorize today’s diverse automotive offerings and common usage of the term runs contrary to most long-held definitions.
There is, however, a common thought that seems to run through almost all of the outlooks on the meaning of sports cars. If a car is designed with high performance or race-like capabilities in mind, it can probably be safely termed a sports car. Some purists may balk at such a liberal perspective, but alternative definitions fall far short of accurately distinguishing sports cars from regular production models.
