Coupe vs. Convertible Performance Comparison

Some automakers sell certain two-door models as coupes and convertibles. California's weather makes convertible cars attractive for many drivers. However, there are several factors to contemplate when comparing these vehicles with coupes. For some motorists, one important consideration is performance. These two types of vehicles offer different benefits regarding acceleration, braking and handling.

Explanation

Most performance variations are mainly linked to weight differences. Convertibles normally weigh significantly more than coupes. This disparity often ranges from about 250 to 400 pounds. Many people believe that convertibles weigh less because they have lighter roofs. However, insulation and mechanisms add numerous pounds. Differences in aerodynamics also play a role.

These factors have a considerable impact on fuel economy. With the top up, a convertible may consume just as much or slightly less gas than a coupe. However, this changes significantly when a driver lowers the top. It can cut gas mileage by around 15 percent. Results may vary depending on a car's speed; faster driving tends to amplify the negative effect.

Acceleration

Coupes frequently reach 60 miles per hour sooner than convertibles. For instance, one well-known convertible takes 0.6 seconds longer than the coupe version of the same model. On the other hand, a major automotive magazine found that a high-performance German coupe accelerated to 60 mph in 4.7 seconds. Its convertible counterpart did so one-tenth of a second faster.

Braking

The effect on braking is usually marginal. In recent years, a top auto magazine measured the stopping distances of two American and German sports cars. It determined how far the vehicles traveled as their speeds decreased from 60 to zero mph. Surprisingly, the convertible versions of both models had stopping distances that were one foot shorter. This is only an improvement of about 1 percent.

Rigidity

A coupe has a fixed roof made of metal, so the structure of this vehicle is comparatively rigid. As a result, these cars deliver somewhat superior handling. Motorists don't often notice the difference in normal everyday driving. However, a rigid structure can make a big difference when people take part in racing competitions.

To sum it up, a coupe usually accelerates faster and handles better than a convertible. It generally consumes a bit less fuel as well. At the same time, convertibles' brakes bring them to a stop slightly faster. Drivers can find both kinds of vehicles when they shop for a new Kia Orange, California.
